500 Series EQs – Shaping Frequencies in a Modular Workflow
Equalizers are among the most essential tools in audio production. In the 500 Series format, they combine precise tone shaping with the flexibility of a modular system, allowing engineers and producers to tailor their signal path to specific requirements. Control, tone shaping, and flexibility are at the heart of their role.
Whether during recording, mixing, or mastering, 500 Series EQs help structure signals, create space within a mix, and turn sonic decisions into deliberate actions directly within the analog signal path.
The question is rarely which equalizer is objectively “the best.” What matters is which module best suits the source material, workflow, musical style, and desired sonic outcome.
Today, the 500 Series format offers an enormous variety of equalizer designs. From classic API-inspired circuits and inductor-based designs to modern parametric solutions, there are specialized tools available for virtually every application in the signal chain.
At the same time, 500 Series EQs differ significantly in character, workflow, and intended use. Some modules are designed for maximum precision and transparency, while others intentionally introduce color, saturation, or the distinctive character associated with classic console designs.
One of the greatest advantages of modular systems is the ability to combine different sonic philosophies within a single rack. This allows signal paths to be tailored specifically for recording, mixing, or mastering applications.
In practice, the number of frequency bands or available features is rarely what matters most. What matters is whether an equalizer supports musical decision-making and integrates naturally into an existing workflow.
That is why you will not find a random collection of 500 Series EQs at Peakhouse Audio. Our selection is based on hands-on studio experience, direct comparisons, and modules that have proven themselves in professional recording, mixing, and mastering environments.
If you are unsure which 500 Series EQ best suits your setup, we are happy to help with equipment selection, integration, and signal-flow planning.
Less focus on frequency curves—and more focus on modules that make sonic decisions faster, more musical, and more repeatable.

Cranborne Audio 500 Series Bundle
Cranborne Audio 500 Series Bundle The Cranborne Audio 500 Series Bundle combines three of Cranborne Audio's most distinctive analogue 500 Series modules to create a complete recording and mixing channel strip: the ultra-transparent Camden 500 microphone preamp, innovative Carnaby 500 Harmonic EQ, and highly versatile Brick Lane 500 Compressor. Together they cover the three fundamental stages of professional analogue signal processing – preamplification and saturation, tonal shaping, and dynamics control. What makes this combination particularly interesting is Cranborne's approach to analogue design. Rather than simply recreating established vintage circuits, all three modules employ original modern topologies. Camden 500 combines exceptionally clean amplification with switchable Mojo saturation, Carnaby 500 uses Cranborne's proprietary Harmonic EQ® technology instead of conventional EQ processing, and Brick Lane 500 completes the chain with a highly flexible Modal PWM compressor offering six distinct compression personalities. The resulting channel strip can therefore move seamlessly from almost completely transparent processing to pronounced analogue character. Sound Character The Camden 500 provides the foundation of the signal chain. In Clean mode it is exceptionally neutral, fast and quiet, offering up to 68 dB of gain. Microphones and instruments can therefore be amplified without automatically imposing a pronounced vintage signature. When more character is desirable during recording, the Mojo circuit provides two different analogue saturation flavours. Thump introduces additional harmonic energy into the low-frequency region, giving bass, kick drums and vocals additional perceived weight. Cream generates more complex harmonic saturation and transient shaping, evoking some of the characteristics associated with classic valve and transformer stages. The Carnaby 500 takes a fundamentally different approach from conventional parametric equalisation. Its three bands use Cranborne's proprietary Harmonic EQ® technology, generating frequency-dependent harmonic saturation as part of the equalisation process. Carnaby therefore changes not only the level of a frequency region but also its harmonic structure. The result can provide organic, musical enhancement at subtle settings or far more pronounced creative tone shaping when pushed harder. The Brick Lane 500 completes the chain with comprehensive dynamics processing. Its Modal PWM architecture provides six distinct compression personalities, covering an unusually wide range of behaviours – from smooth level control to fast, punchy compression and deliberately characterful dynamics processing. Precision detented controls also make settings easy to recall. Together, the three modules form an exceptionally versatile analogue chain for tracking, mixing and sound design – pristine and neutral when fidelity is paramount, or increasingly dense, harmonically rich and characterful when creative processing is required.

Cranborne Audio Carnaby 500
Cranborne Audio Carnaby 500 The Cranborne Audio Carnaby 500 is a revolutionary 3-band HarmonicEQ® for the 500 Series format and the world's first analogue equalizer to shape frequencies using harmonic saturation rather than conventional boost and cut circuits. Instead of simply altering frequency response, the Carnaby 500 generates carefully controlled harmonic content that naturally enhances the source while maintaining the familiar workflow of a traditional analogue EQ. Each of its three fully analogue EQ bands features a dedicated HarmonicEQ® circuit with harmonics specifically tailored for its frequency range. Parametric low and high shelving bands are complemented by a wide-ranging fixed-Q mid band, allowing everything from subtle enhancement to bold analogue coloration. With ±20 dB input and output trim, stepped controls, True Bypass and Cranborne's innovative OptoSync™ technology, two Carnaby 500 modules can be wirelessly linked into a perfectly matched stereo pair, while automatic calibration ensures identical tracking between channels. Sound Character The Carnaby 500 sounds unlike any conventional analogue EQ. Rather than merely boosting or cutting frequencies, every adjustment introduces carefully controlled harmonic enhancement that makes sources feel larger, richer and more three-dimensional. High frequencies become airy and open without harshness, the midrange gains presence and depth, while the low end becomes fuller and more authoritative without sacrificing definition. A defining characteristic is its dynamic response: as the input signal is driven harder, both harmonic saturation and the EQ effect increase naturally. This allows the Carnaby 500 to range from subtle analogue sweetening to bold harmonic coloration. Whether used on vocals, drums, guitars, synthesizers or stereo buses, it delivers a uniquely musical character that traditional equalizers simply cannot replicate.

Mäag Audio EQ4-500
Mäag Audio EQ4-500The Mäag Audio EQ4-500 is a professional single-channel 6-band equalizer for the 500 Series format, bringing the fundamental design philosophy of the larger EQ4M into a compact module. Combining five broad musical EQ bands with Mäag's signature AIR BAND®, the EQ4-500 is designed less as a surgical correction tool and more as a musical tone shaper for recording and mixing. The current version complements the established circuit design with a refreshed front panel, improved spacing between controls and a true hardwire bypass.The five main bands operate at fixed frequencies of 10 Hz (SUB), 40 Hz, 160 Hz, 650 Hz and 2.5 kHz. The first four sections use broad bell-shaped curves, while the 2.5 kHz band operates as a shelving EQ. All five bands provide an unusually asymmetrical adjustment range of up to +15 dB boost and -4.5 dB cut. Centre detents at 0 dB make settings quick to establish and easy to recall.In addition, the EQ4-500 incorporates Mäag's renowned AIR BAND®, an exceptionally broad high-frequency shelving filter. The current EQ4-500 provides selectable frequencies of 2.5, 5, 10, 15, 20 and 40 kHz, plus an Off position, while the dedicated Air Gain control provides up to +20 dB of boost. Due to its broad transitional slope, frequencies below the selected point are also affected, allowing presence, openness and perceived detail to be shaped differently from a conventional high-frequency EQ.Sound CharacterSonically, the EQ4-500 follows the classic Mäag philosophy: open, transparent and musical with very low phase shift. Its individual filters are intentionally broad and interact with each other. Rather than creating isolated surgical changes, adjustments reshape the overall tonal balance in a fluid and musical way. Small combinations of boost and cut can therefore produce surprisingly significant results.The AIR BAND® is the defining sonic feature of the EQ4-500. It can add openness and presence to the upper frequencies without necessarily introducing the hardness or aggression associated with conventional presence EQ. It is particularly effective on vocals, acoustic instruments, overheads and stereo buses, where it can enhance air and perceived detail. The 20 and 40 kHz settings provide particularly broad and subtle enhancement, while the lower settings reach more noticeably into the audible presence range.The 10 Hz SUB band is equally distinctive. Although its centre frequency lies below the fundamental range of most musical material, its broad curve extends into the audible bass region and can add weight and foundation. The 40, 160 and 650 Hz bands provide control over low-end punch, warmth, body and lower-midrange balance, while the 2.5 kHz shelf shapes presence and articulation. The result is an equalizer particularly well suited to broad musical tone shaping and sweetening.Highlights✔ professional single-channel 6-band equalizer✔ compact 500 Series module✔ based on the design philosophy of the Mäag Audio EQ4M✔ fully analogue signal path✔ 6 EQ sections✔ four broad bell-shaped filters✔ additional 2.5 kHz shelving filter✔ legendary Mäag AIR BAND®✔ selectable AIR BAND® frequency✔ AIR BAND® frequencies: Off / 2.5 / 5 / 10 / 15 / 20 / 40 kHz✔ dedicated AIR GAIN control✔ AIR GAIN provides up to +20 dB boost✔ 10 Hz SUB band✔ 40 Hz band✔ 160 Hz band✔ 650 Hz band✔ 2.5 kHz shelving band✔ main bands provide up to +15 dB boost / -4.5 dB cut✔ centre detents at 0 dB✔ broad, musical filter curves✔ minimal phase shift✔ interactive EQ-band behaviour✔ particularly suitable for recording and mixing✔ excellent for vocal sweetening✔ suitable for individual tracks and stereo buses✔ current model with redesigned front panel✔ increased spacing between frequency controls✔ improved visibility and ergonomics✔ true hardwire In/Out bypass✔ bypass circuit derived from the EQ4M✔ green signal-present LED✔ signal indication from -20 dBu✔ red peak LED✔ peak indication at +23 dBu✔ high analogue headroom of +25 dBu✔ THD + Noise below 0.005%✔ extended frequency response to 75 kHz✔ occupies only one 500 Series slot✔ compatible with 500VPR systemsTypical Applications✔ vocal recording✔ vocal sweetening✔ lead vocals✔ backing vocals✔ acoustic guitars✔ electric guitars✔ bass✔ piano✔ strings✔ synthesizers✔ drum machines✔ snare drum✔ kick drum✔ overheads✔ drum rooms✔ percussion✔ drum bus✔ instrument buses✔ stereo keyboards✔ electronic music✔ individual track processing during recording✔ EQ processing during mixing✔ AIR BAND® for open and airy top end✔ adding presence without aggressive high-frequency character✔ low-frequency shaping with the 10 Hz SUB band✔ adding foundation to bass and kick✔ adding warmth and body around 160 Hz✔ midrange shaping at 650 Hz✔ presence control with the 2.5 kHz shelf✔ broad musical tone shaping✔ subtle sonic enhancement✔ analogue hybrid studios✔ professional 500 Series racks✔ recording chains following microphone preamps✔ mix-bus applications✔ creative tone shapingTechnical Specifications✔ model: EQ4-500✔ manufacturer: Mäag Audio✔ product type: single-channel 6-band equalizer✔ format: 500 Series✔ channels: 1✔ slots required: 1✔ EQ bands: 6✔ SUB band: 10 Hz✔ low band: 40 Hz✔ low-mid band: 160 Hz✔ mid band: 650 Hz✔ high band: 2.5 kHz shelf✔ AIR BAND®: Off / 2.5 / 5 / 10 / 15 / 20 / 40 kHz✔ SUB / 40 Hz / 160 Hz / 650 Hz: bell filters✔ 2.5 kHz: shelving filter✔ AIR BAND®: high-frequency shelving filter✔ main band boost: up to +15 dB✔ main band cut: down to -4.5 dB✔ AIR GAIN: up to +20 dB✔ main band zero position: centre detent✔ bypass: true hardwire In/Out bypass✔ signal LED: from -20 dBu✔ peak LED: at +23 dBu✔ frequency response: -2 dB points at 10 Hz and 75 kHz✔ nominal input impedance: 48 kΩ balanced✔ nominal output impedance: 50 Ω balanced✔ headroom: +25 dBu✔ THD + Noise: < 0.005%✔ power: supplied by compatible 500 Series rack✔ rack compatibility: 500VPR / API-compatible 500 Series systems
Mäag Audio EQ4-500-BK
Mäag Audio EQ4-500-BKThe Mäag Audio EQ4-500-BK is a professional single-channel 6-band equalizer for the 500 Series format and the black version of the current EQ4-500. Based on the design philosophy of the larger EQ4M, this compact module combines five broad musical EQ bands with Mäag's signature AIR BAND®. Rather than functioning as a surgical correction EQ, the EQ4-500-BK is designed as a musical tone-shaping tool for recording and mixing, allowing broad tonal changes with minimal phase shift. Its black faceplate provides a discreet alternative to Mäag's traditional blue design.The five main bands operate at fixed frequencies of 10 Hz (SUB), 40 Hz, 160 Hz, 650 Hz and 2.5 kHz. The first four sections use broad bell-shaped curves, while the 2.5 kHz band operates as a shelving EQ. All five bands provide up to +15 dB of boost and -4.5 dB of cut, with centre detents at 0 dB. Their broad filter shapes are deliberately designed for musical processing, allowing fast tonal shaping while preserving the fundamental character of the source.In addition, the legendary AIR BAND® provides an exceptionally broad high-frequency shelving filter. Its operating frequency can be selected at 2.5, 5, 10, 15, 20 or 40 kHz, or switched completely off, while the dedicated AIR GAIN control provides up to +20 dB of boost. The updated BK version also features a redesigned front panel with increased spacing between the frequency controls and a true hardwire In/Out bypass, using the same bypass circuit found in the EQ4M.Sound CharacterSonically, the EQ4-500-BK represents the classic Mäag philosophy: open, transparent and highly musical. Its broad filters are particularly effective for large-scale tonal adjustments and sweetening. Rather than surgically isolating individual frequencies, they reshape the overall tonal balance naturally while largely preserving the original structure of the source.The defining sonic feature is the AIR BAND®. Due to its exceptionally broad shelving characteristic, it does not affect only frequencies above the selected point; its transitional slope also reaches into lower frequencies. This can make vocals, overheads, acoustic instruments and complete mixes sound more open and detailed without necessarily introducing the hardness associated with a conventional presence boost.The unusually low-frequency bands are equally important to the Mäag concept. The 10 Hz SUB band extends into the audible bass range due to its broad curve and can add weight and foundation to a source. The 40 Hz band shapes low-end depth and punch, while 160 and 650 Hz affect warmth, body and midrange structure. Finally, the 2.5 kHz shelf controls presence and articulation. Combined with the AIR BAND®, these sections create an equalizer where relatively small control movements can produce clearly audible yet musically broad tonal changes.Highlights✔ professional single-channel 6-band equalizer✔ black BK version of the Mäag Audio EQ4-500✔ sleek black faceplate✔ compact 500 Series module✔ based on the design philosophy of the Mäag Audio EQ4M✔ fully analogue signal path✔ 6 EQ sections✔ four broad bell-shaped filters✔ additional 2.5 kHz shelving filter✔ legendary Mäag AIR BAND®✔ selectable AIR BAND® operating frequency✔ AIR BAND® frequencies: Off / 2.5 / 5 / 10 / 15 / 20 / 40 kHz✔ dedicated AIR GAIN control✔ AIR GAIN provides up to +20 dB boost✔ 10 Hz SUB band✔ 40 Hz band✔ 160 Hz band✔ 650 Hz band✔ 2.5 kHz shelving band✔ main bands provide up to +15 dB boost / -4.5 dB cut✔ centre detents at 0 dB✔ broad, musical filter curves✔ minimal phase shift✔ particularly suitable for recording and mixing✔ excellent for vocal sweetening✔ suitable for individual tracks and complete mixes✔ updated front panel with new labeling✔ increased spacing between frequency controls✔ improved ergonomics and visibility✔ true hardwire In/Out bypass✔ hardwire bypass circuit derived from the EQ4M✔ green signal-present LED✔ signal indication from -20 dBu✔ red peak LED✔ peak indication at +23 dBu✔ high analogue headroom of +25 dBu✔ THD + Noise < 0.005%✔ extended frequency response to 75 kHz✔ occupies only one 500 Series slot✔ compatible with 500VPR systemsTypical Applications✔ vocal recording✔ vocal sweetening✔ lead vocals✔ backing vocals✔ acoustic guitars✔ electric guitars✔ bass✔ piano✔ strings✔ synthesizers✔ drum machines✔ snare drum✔ kick drum✔ overheads✔ drum rooms✔ percussion✔ drum bus✔ instrument buses✔ stereo keyboards✔ electronic music✔ individual track processing during recording✔ EQ processing during mixing✔ AIR BAND® for open and airy top end✔ adding presence without aggressive high-frequency character✔ low-frequency shaping with the 10 Hz SUB band✔ adding foundation to bass and kick✔ adding warmth and body around 160 Hz✔ midrange shaping at 650 Hz✔ presence control with the 2.5 kHz shelf✔ broad musical tone shaping✔ subtle sonic enhancement✔ analogue hybrid studios✔ professional 500 Series racks✔ recording chains following microphone preamps✔ mix-bus applications✔ creative tone shapingTechnical Specifications✔ model: EQ4-500-BK✔ manufacturer: Mäag Audio✔ product type: single-channel 6-band equalizer✔ version: black faceplate✔ format: 500 Series✔ channels: 1✔ slots required: 1✔ EQ bands: 6✔ SUB band: 10 Hz✔ low band: 40 Hz✔ low-mid band: 160 Hz✔ mid band: 650 Hz✔ high band: 2.5 kHz shelf✔ AIR BAND®: Off / 2.5 / 5 / 10 / 15 / 20 / 40 kHz✔ SUB / 40 Hz / 160 Hz / 650 Hz: bell filters✔ 2.5 kHz: shelving filter✔ AIR BAND®: high-frequency shelving filter✔ main band boost: up to +15 dB✔ main band cut: down to -4.5 dB✔ AIR GAIN: up to +20 dB✔ main band zero position: centre detent✔ bypass: true hardwire In/Out bypass✔ signal LED: from -20 dBu✔ peak LED: at +23 dBu✔ frequency response: -2 dB points at 10 Hz and 75 kHz✔ nominal input impedance: 48 kΩ balanced✔ nominal output impedance: 50 Ω balanced✔ headroom: +25 dBu✔ THD + Noise: < 0.005%✔ power: supplied by compatible 500 Series rack✔ rack compatibility: 500VPR / API-compatible 500 Series systems
Mother Audio VIVID
Mother Audio VIVID VIVID, 3 band inductor based eq for 500 series, represents our attempt to reformulate the well-known classic British design, increase its spatial and sonic qualities and make it more usable for demanding tasks such as mastering applications or processing groups of acoustic instruments. In fact, any source that contains a lot of spatial details which should be preserved and not damaged, can benefit from the quality that Vivid offers. The module was designed and manufactured in Serbia, by a small group of dedicated people, including hand-wound transformers, which we are particularly proud of. The eq module contains a specially designed input transformer, wound on an unusually large core(similar to one that can be find in the bv08 , legendary U47 transformer). The result is increased headroom and a very relaxed, lush and focused sound. The entire circuit is discrete class A, and contains two custom inductors, which are also manually produced in-house. After countless tests, we decided to use tantalum capacitors for all couplings and in other critical places (9 of them actually), similar to what can be seen on old Siemens devices, and this really made an audible contribution to the overall sound impression. How does it sound?The sound is big, open, never aggressive.Vivid is extremely musical, and it is very easy to find a setting that suits any material. What can it be used on?From vocals, acoustic instruments, equalization of ambient microphones, to stereo material processing.You can use it on “djent” low tuned guitars or a live recorded choral music,doesn't matter , it will always sound great and be a useful tool.

Mother Audio WAI 2950
Mother Audio WAI 2950 WAI (wire and iron) 2950, is a 3 band, completely discrete class A inductor based, 500 series eq. In a way, we recreated the legendary w295, an eq famous for its magically beautiful “high shelf” and real vintage vibe, the secret weapon of many producers over the past decades. Input and output are balanced by our custom high class transformers. A special challenge was the output transformer, which, with the integrated LPF at 20khz is a really critical element to not lose the well-known sonic character, and the choice ultimately fell on the 50%Nickl core. Also, the impedance of the input transformer, (which in the genuine unit was relatively low) was increased to today's standards and all this resulted in an extended low freq response and a slightly “excited” sound, if we compare it with the Siemens module. The pcb board is full of NOS bsx46 Phillips transistors, and as much as possible Siemens NOS film capacitors. How does it sound?Completely magical, huge, but still focused low end and incredibly sweet highs, creamy mid range, very characteristic for an inductor based circuit.What can it be used on?Anywhere where you actually want character and sweetness.

Pulse Techniques EQP-500X
Pulse Techniques EQP-500XThe Pulse Techniques EQP-500X is a premium passive program equalizer in the API 500 Series format, combining the legendary sound of original Pultec equalizers with a discrete solid-state amplification stage. Based on the classic EQP-1A3-SS and EQP-1S3-SS concepts, EQP-500X combines the characteristic passive Pultec filter circuitry with a genuine API 2520 operational amplifier and a high-quality Triad output transformer.The origins of this design date back to the early 1970s, when Pulse Techniques first condensed the classic tube-based EQP-1A into the more compact EQP-1A3 format and subsequently developed a solid-state version. While retaining the original input transformer and passive equalizer circuitry, the tube amplification stage was replaced by a discrete solid-state design.The result is an equalizer that combines the unmistakably musical character of classic Pultec filters with direct response, excellent dynamics and a tight, controlled low end. Particularly on kick drums, bass guitars and other transient-rich sources, the solid-state version is frequently appreciated for its punchy and defined sonic character.With independent low-frequency Boost and Attenuation controls together with flexible high-frequency filters, EQP-500X provides the characteristic Pultec EQ curves. Low frequencies can be boosted and attenuated simultaneously, creating tonal contours that extend far beyond the capabilities of a conventional shelving equalizer.Sound CharacterThe EQP-500X combines the musical smoothness and natural response of passive Pultec filters with the immediacy and transient response of a premium solid-state amplification stage. Compared with the classic tube versions, the solid-state design is often described as slightly punchier, faster and particularly controlled in the low-frequency range.The Low-Frequency section is one of the EQP-500X's defining strengths. By combining Boost and Attenuation simultaneously, characteristic frequency contours can be created that add depth and weight to the low end without making it sound uncontrolled or excessively dominant. On kick drums and bass guitars in particular, this allows an effective combination of foundation, punch and definition.The High-Frequency section provides both broad tonal enhancement and more focused shaping. Nine selectable Peak Boost frequencies from 1 to 16 kHz allow presence, articulation and openness to be adjusted with considerable flexibility. Two additional High-Shelf Boost frequencies and three High-Shelf Attenuation frequencies further expand the available tonal options.Combining the different filter sections makes it possible to create complex, musical EQ curves. Vocals can gain presence, acoustic instruments can sound more open and complete mixes can benefit from additional depth and clarity. Throughout the process, the passive filter architecture retains the smooth and intuitive working character of a genuine Pultec equalizer.Highlights✔ genuine Pulse Techniques Pultec Program Equalizer✔ premium passive equalizer in the API 500 Series format✔ based on classic EQP-1A3-SS and EQP-1S3-SS concepts✔ authentic passive Pultec filter architecture✔ discrete solid-state amplification stage✔ genuine API 2520 operational amplifier✔ premium Triad output transformer✔ transformer-coupled audio signal path✔ characteristic Pultec sound with direct transient response✔ tight, controlled and punchy low-frequency performance✔ independent Low-Frequency Boost and Attenuation controls✔ simultaneous boosting and attenuation of low frequencies✔ classic Pultec Low-End Trick✔ four selectable low-frequency positions✔ Low-Frequency Boost up to +13.5 dB✔ Low-Frequency Attenuation up to 17.5 dB✔ nine selectable High-Frequency Peak Boost frequencies✔ Peak Boost from 1 to 16 kHz✔ High-Frequency Peak Boost up to +18 dB✔ additional High-Frequency Shelf Boost function✔ High-Shelf Boost at 5 and 10 kHz✔ High-Frequency Shelf Attenuation✔ High-Shelf Attenuation at 5, 10 and 20 kHz✔ independent Boost and Attenuation adjustment✔ musical, broad tonal shaping✔ particularly effective on kick drums, bass, vocals and mix bus✔ high maximum output level of +21 dBm✔ compact 500 Series format✔ handcrafted in Fort Collins, Colorado, USATypical Applications✔ kick drum processing✔ bass guitar and synth bass✔ vocal recording and mixing✔ acoustic guitars✔ electric guitars✔ synthesizers and keyboards✔ drum bus processing✔ stereo mix-bus equalization with two modules✔ analogue tone enhancement✔ characteristic Pultec bass processing✔ simultaneous low-frequency boost and attenuation✔ targeted presence enhancement✔ musical high-frequency shaping✔ air and brilliance enhancement✔ individual instrument processing✔ stem processing✔ hybrid mixing✔ analogue summing and mixing chains✔ professional recording and mixing studios✔ premium 500 Series outboard systemsTechnical Specifications✔ manufacturer: Pulse Techniques✔ model: EQP-500X✔ product type: passive program equalizer with solid-state gain stage✔ format: API 500 Series✔ channels: 1 / mono✔ filter architecture: passive✔ amplification stage: genuine API 2520 operational amplifier✔ output transformer: Triad✔ input stage: transformer-coupledLow-Frequency Boost✔ filter type: Low-Frequency Shelf Boost✔ frequencies: 30 / 40 / 70 / 100 Hz✔ boost range: 0 to +13.5 dB✔ frequency positions: 4Low-Frequency Attenuation✔ filter type: Low-Frequency Shelf Attenuation✔ frequencies: 30 / 40 / 70 / 100 Hz✔ attenuation range: 0 to 17.5 dB✔ frequency positions: 4✔ simultaneous Boost and Attenuation supportedHigh-Frequency Peak Boost✔ filter type: High-Frequency Peak Boost✔ frequencies: 1 / 2 / 3 / 4 / 5 / 8 / 10 / 12 / 16 kHz✔ boost range: 0 to +18 dB✔ frequency positions: 9High-Frequency Shelf Boost✔ filter type: High-Frequency Shelf Boost✔ frequencies: 5 / 10 kHz✔ boost range: 0 to +14 dBHigh-Frequency Shelf Attenuation✔ filter type: High-Frequency Shelf Attenuation✔ frequencies: 5 / 10 / 20 kHz✔ attenuation range: 0 to 16 dBAudio Specifications✔ input impedance: approximately 600 Ω✔ output impedance: approximately 50 Ω✔ noise: below -80 dBm✔ distortion: ≤ 0.15% at +10 dBm into 600 Ω✔ amplifier frequency response including input and output transformers: 20 Hz–20 kHz, +0/-1 dB, 1 kHz reference✔ maximum output level: +21 dBm✔ power: supplied by a compatible 500 Series rack✔ manufacturing: handcrafted in the USAThe Pulse Techniques EQP-500X brings the authentic sound of an original Pultec Program Equalizer into the compact 500 Series format. Its combination of passive filters, genuine API 2520 operational amplifier and Triad output transformer delivers classic Pultec tonal shaping with the direct, punchy and controlled character of a solid-state design.The unique ability to boost and attenuate low frequencies simultaneously makes EQP-500X particularly effective on kick drums, bass guitars and complete mixes. At the same time, its extensive high-frequency filtering options provide a musical way to shape presence, openness and brilliance.For professional recording and mixing studios, the EQP-500X is an excellent choice when the unmistakable character of a genuine Pultec equalizer is required together with the flexibility and compact footprint of a modern 500 Series system.
Pulse Techniques MEQ-500
Pulse Techniques MEQ-500The Pulse Techniques MEQ-500 is a premium passive midrange equalizer in the API 500 Series format, combining the legendary tonal character of the Pultec MEQ-5 with a modern solid-state amplification stage. Developed as the Jack Douglas Edition, the classic filter design has been expanded in collaboration with renowned producer and engineer Jack Douglas to provide greater flexibility for contemporary recording and mixing applications.At its core is the musical shaping of the so-called power region between approximately 300 Hz and 5 kHz. This frequency range plays a fundamental role in the perception of body, character, presence and definition in recorded sound. With three independently adjustable filter sections, MEQ-500 makes it possible to create complex tonal contours that would often require several combined filters on a conventional parametric equalizer.The passive EQ circuitry is complemented by a solid-state gain stage based on the API 2520 operational amplifier. A high-quality Triad output transformer completes the analogue signal path. This combination brings together the characteristic Pultec filter curves with a direct, punchy and controlled sonic response.Compared with the original MEQ-5, the available frequency selections have been expanded. Additional positions at 1.2 and 1.5 kHz in the low-mid band and 1.2 and 8 kHz in the high-mid band provide greater tonal flexibility. The Q characteristics of selected high-mid settings have also been refined.Sound CharacterThe MEQ-500 delivers musical, full-bodied and precise midrange shaping. Its passive filters create natural-sounding tonal changes, while the solid-state amplification stage provides direct response and controlled reproduction.The Low-Mid Boost section is particularly useful for adding body and substance to vocals, guitars and other instruments. The High-Mid Boost section can enhance articulation, attack and presence, while the independent Dip section allows unwanted midrange energy to be reduced simultaneously.One of its defining strengths is the ability to combine all three filter sections. By overlapping boost and attenuation curves, MEQ-500 produces characteristic Pultec EQ contours that can make guitars sound fuller and more present, vocals more open or snare drums more defined and powerful.The additional frequency selections developed with Jack Douglas further extend its versatility. The new positions between 1 and 1.5 kHz are especially useful for detailed shaping of guitars, vocals and keyboards, while the 8 kHz setting offers additional possibilities for presence and upper-frequency definition.Highlights✔ premium passive midrange equalizer in the 500 Series format✔ Jack Douglas Edition with expanded frequency selections✔ based on the legendary Pultec MEQ-5✔ classic passive Pultec filter architecture✔ solid-state gain stage based on the API 2520✔ premium Triad output transformer✔ three independently adjustable EQ sections✔ Low-Mid Peak Boost✔ High-Mid Peak Boost✔ dedicated Midrange Dip/Attenuation section✔ simultaneous boosting and attenuation of different midrange frequencies✔ Low-Mid Boost with 7 selectable frequencies✔ High-Mid Boost with 7 selectable frequencies✔ Dip section with 11 selectable frequencies✔ additional Low-Mid frequencies at 1.2 and 1.5 kHz✔ additional High-Mid frequencies at 1.2 and 8 kHz✔ refined Q characteristics for selected high-mid settings✔ Low-Mid Boost up to +10 dB✔ High-Mid Boost up to +8 dB✔ Midrange Attenuation up to 10 dB✔ musical and distinctive Pultec EQ curves✔ particularly effective on guitars, vocals, bass and keyboards✔ versatile processing of critical presence and midrange frequencies✔ high maximum output level of +21 dBm✔ compact API 500 Series format✔ designed and manufactured by Pulse Techniques in the USATypical Applications✔ vocal recording and mixing✔ lead vocal tone shaping✔ electric guitars✔ acoustic guitars✔ bass guitars✔ synthesizers and keyboards✔ snare drum processing✔ toms and percussion✔ brass and strings✔ musical midrange correction✔ targeted presence enhancement✔ reduction of unwanted midrange resonances✔ improved articulation and definition✔ combined midrange boosting and attenuation✔ characterful analogue tone shaping✔ recording and mixing chains✔ hybrid mixing✔ professional studios using 500 Series outboardTechnical Specifications✔ manufacturer: Pulse Techniques✔ model: MEQ-500 / Jack Douglas Edition✔ product type: passive midrange equalizer with solid-state gain stage✔ format: API 500 Series✔ channels: 1 / mono✔ filter architecture: passive✔ amplifier: API 2520-based solid-state circuit✔ output transformer: Triad✔ EQ sections: 3 independently adjustable filter sectionsLow-Mid Peak Boost✔ filter type: Peak Boost✔ frequencies: 200 / 300 / 500 / 700 / 1,000 / 1,200 / 1,500 Hz✔ gain range: 0 to +10 dB✔ frequency positions: 7High-Mid Peak Boost✔ filter type: Peak Boost✔ frequencies: 1.2 / 1.5 / 2 / 3 / 4 / 5 / 8 kHz✔ gain range: 0 to +8 dB✔ frequency positions: 7Midrange Dip / Attenuation✔ filter type: Midrange Dip✔ frequencies: 200 / 300 / 500 / 700 Hz✔ additional frequencies: 1 / 1.5 / 2 / 3 / 4 / 5 / 7 kHz✔ gain range: 0 to -10 dB✔ frequency positions: 11Audio Specifications✔ input impedance: approximately 600 Ω✔ output impedance: approximately 50 Ω✔ noise: below -80 dBm✔ distortion: ≤ 0.15% at +10 dBm into 600 Ω✔ amplifier frequency response including transformers: 20 Hz–20 kHz, +0/-1 dB, 1 kHz reference✔ maximum output level: +21 dBm✔ power: supplied by a compatible 500 Series rackThe Pulse Techniques MEQ-500 combines the unmistakable character of classic Pultec midrange equalizers with the dynamics and immediacy of a premium solid-state circuit.
