Mäag Audio EQ4-500 The Mäag Audio EQ4-500 is a single channel 6-band equalizer module that fits into a single slot of the popular 500VPR series racks. Like the EQ2, many features and the design philosophies of the Mäag Audio EQ4M standalone equalizer are incorporated into the EQ4-500 Series equalizer.   Like the 1U standalone Mäag Audio EQ4M stereo mastering equalizer, the EQ4-500 has six EQ band sections divided into four, fixed frequency bell-shaped peaking equalizer sections, a 2.5 kHz shelving equalizer section, and the Air Band shelf equalizer with a choice of: off, 2.5, 5, 10, 15, 20, and 40 kHz frequencies. The five frequency bands in the main section are: Sub or 10 Hz, 40 Hz, 160 Hz, 650 Hz, and the 2.5 kHz shelf EQ. The Air Gain allows for up to +20 dB boost for the Air Band shelving equalizer.   The five EQs in the main section have a boost/cut range of +15 dB and -4.5 dB with center position detent at 0 db. The EQ4-500 has both a green signal present LED at -20 dBu and a red peak LED that flashes with +23 dBu peaks. There is also an In/Out bypass switch for the entire module.   The Mäag Audio EQ4-500 Series 6-Band Equalizer is the ultimate equalizer for any 500VPR rack owner that, along with the access to the Air Band, will become your first “go to” tool for both recording and mixing duties.

Mäag Audio EQ4M In 1993, Cliff Maag first introduced the AIR BAND to the audio world in the NTI EQ3. The EQ3 was a dual channel 6-band EQ powered in a 19 inch rack and to this day is hailed as one of the most musical equalizers ever made. Over two decades later, Maag Audio is Back in Rack! Introducing the Maag Audio EQ4M, a 6-band Dual Channel Mastering EQ. More Power The EQ4M rides on extremely clean +-18v rails without the need of any supporting chassis or power source. Just plug it in and make music. More Headroom More power, means more headroom. The EQ4M's extra 3v power boosts headroom to +29 dBu. More Control The EQ4M offers more control with its true in/out bypass, a very transparent INPUT ATTN (attenuator), and an extra 15 kHz selection on the AIR BAND.  All controls are stepped (detented). The frequency bands are the same as the EQ4-500 with the exception of the extra 15kHz for the AIR BAND.

Mäag Audio PREQ4-500 THE PREQ4 IS AN “ALL IN ONE” CHANNEL STRIP THAT UPDATES THE PREQ3 MODULE AND FITS INTO THE STANDARD 500VPR RACK. UP TO 65 DB OF EXTREMELY CLEAN GAIN IS AVAILABLE TO HANDLE LOW OUTPUT RIBBON MICS AND/OR VERY QUIET SOUND RECORDINGS FOR FOLEY/FILM APPLICATIONS THAT REQUIRE HIGH GAIN WITH A LOW NOISE FLOOR.   THE PREQ4 FRONT PANEL STARTS WITH SEPARATE +48-VOLT PHANTOM POWER ON/OFF SWITCH AND PHASE REVERSE (POLARITY) SWITCHES. NEXT IS A SWITCHABLE -20 DB ATTENUATOR PAD THAT IS PLACED IN THE CIRCUIT JUST BEFORE THE INPUT TRANSFORMER TO AVOID SATURATION UNNECESSARILY WITH AN EXCESSIVELY, “HOT” MICROPHONE SIGNAL. ADJACENT TO THE PAD SWITCH IS THE HIGH PASS FILTER IN/OUT SWITCH. THE HIGH PASS FILTER HAS A VERY GENTLE SLOPE STARTING AT 160 HZ AND IS -3 DB DOWN AT 70 HZ. ALL FOUR OF THESE SWITCHES—THE 48-VOLT PHANTOM, PHASE REVERSE, -20 DB PAD AND HIGH PASS FILTER ALL HAVE LEDS TO CONFIRM THEIR STATUS.   JUST ABOVE IS THE GAIN +20 DB RANGE SWITCH THAT CHANGES THE NOMINAL THROUGHPUT GAIN RANGE FROM EITHER 25 TO 45 DB OVER TO 45 TO 65 DB OF GAIN. THE AIR BAND IN/OUT SWITCH IS NEXT AND THESE TWO SWITCHES ALSO HAVE LED STATUS INDICATORS. WITHIN A DIMLY LIT RECORDING STUDIO, THESE LEDS ARE VITAL TO PROVIDE AN EXTRA LEVEL OF CONFIDENCE AND CONFIRMATION OF THE PEQ4’S CORRECT SETUP AND OPERATION.   NEXT IS THE GAIN CONTROL WITH A GREEN LED TO INDICATE SIGNAL PRESENCE AT -20 DBU AND A RED LED TO INDICATE WHEN THE OUTPUT IS NEAR CLIP AT +23 DBU. ABOVE GAIN IS THE AIR BAND GAIN CONTROL FOR UP TO +12 DB OF BOOST IN THE VARI AIR BAND SECTION. THERE IS A 6-POSITION SWITCH FOR SELECTING THE STARTING FREQUENCY OF THIS SHELVING EQUALIZER OF: 2.5, 5, 10, 20, AND 40 KHZ.   THE PREQ4 IS AN EXCELLENT TRACKING MICROPHONE PREAMPLIFIER WHEN YOU DESIRE A PRISTINE AND UNCOLORED SOUNDING RECORDING. IT PROVIDES A CHOICE OF EXTENDING THE HIGH FREQUENCIES IN A CLEAR AND MUSICAL WAY WITHOUT HARSHNESS.
