IGS Audio 576 Blue Stripe
IGS Audio 576 Blue Stripe The 576 Blue Stripe compressor is inspired by the legendary FET-based compression technology first introduced in the iconic 1176, particularly Revision A, which became a staple in the 1970s for its fast response and distinctive character. At the heart of the 576 Blue Stripe is the same high-quality input transformer that gives the original its warm, harmonically rich tone, complemented by a pure Class A output stage for pristine sound quality. This compressor also features modern upgrades, including a relay-controlled bypass, a versatile 2:1 Ratio setting for more subtle compression, and a powerful Slam Mode for aggressive limiting, reminiscent of the revered 'all-buttons-in’ mode. The 576 Blue Stripe offers a perfect balance of vintage sound and contemporary functionality, ideal for both classic and modern audio applications. What it does The standout feature of the 576 Blue Stripe is its ultra-fast attack time of just 20 µS, making it ideal for precise transient control and shaping even the most dynamic audio sources. The 576 Blue Stripe offers versatile compression with its Ratio buttons, providing a range of six distinct modes of operation to suit different compression needs: 2:1 Ratio: Soft, transparent compression for subtle dynamics control. 4:1 Ratio: Moderate compression, adding more control without sacrificing naturalness. 8:1 Ratio: Severe compression for when you need firm dynamic shaping. 12:1 Ratio: Mild limiting, providing strong control while preserving detail. 20:1 Ratio: Hard limiting for maximum peak control. S (SLAM): Engages the infamous 'All Buttons In’ mode, delivering aggressive, punchy compression that adds unique harmonic saturation. With this flexible range of ratios, the 576 Blue Stripe is capable of handling everything from delicate vocal smoothing to aggressive drum bus compression, making it a versatile tool in any studio environment.
IGS Audio ONE LA 500
IGS Audio ONE LA 500 The IGS ONE LA 500 is an opto-compressor built for the 500 series format. This is the first high voltage vacuum tube 500 series module that is offered by IGS. It is powered with 250V DC from an on-board voltage converter, so it can be plugged into any 500 series rack equipped with a standard power supply. Every single ONE LA is hand made with high quality, matched components (1% metal film resistors, Wima caps). It is equipped with JJ tubes and individually calibrated to give you the unique and unspoiled experience of one of the best opto-compressors in the history – the Teletronix ’68 LA-2A. We have spent hundreds of hours designing the ONE LA, to make sure that it is as simple to use as it is versatile. Not only for harmonically rich vocals and strings, but also for huge and beefy drums and bass instruments. There is something else Three audio transformers (IGS Custom in an audio path and OEP in sidechain) have been used to provide excellent performance and with only two knobs and a single compressor/limiter switch, there is nothing that could go wrong. Additionally, you can replace the photocell easily (special version available)
IGS Audio Rubber Bands 500 Mastering EQ
IGS Audio Rubber Bands 500 Mastering EQ RB500ME is a stereo passive equalizer packed into a double 500-series module. This beast is equipped with transformer balanced inputs and outputs (IGS Custom) as well as a class-A driver circuit. Of course, the entire filtering section is passive and it mirrors analog equalizers from the 60s. There is a separate frequency selector for low cut and boost sections. Top quality potentiometers and ELMA switches were used to achieve outstanding performance. The first ever Stereo Pulteq-style EQ in 500 format The Rubber Bands is a wonderful tool that can add multiple levels of color to any track or mix. The best thing about, it is that you can set it up in various ways, all sounding clearly distinctive and great at the same. This is the device that gives the studio engineer an opportunity to add their own personality to the music.
IGS Audio Tubecore
IGS Audio Tubecore The TUBECORE is a fully symmetric transformer balanced stereo mastering compressor. The structure is based on the typical vari-mu solution. Apart from the classic INPUT, THRESHOLD and OUTPUT controls it introduces a switchable high pass filter in the sidechain, parallel compression (MIX knob), independent ATTACK and RELEASE switches, and user replaceable tubes accessible from the back of the unit. Comfort of use The Tubecore was designed as a studio mastering compressor. It is built using the 3U enclosure, which improves front panel clarity and makes it easier to replace tubes located at the back. The compressor allows you to work either in dual mono or mid/side mode (M/S). The Mode switch has two bypass positions – they both do the same, but we added the second one for your comfort and quick A/B comparing. The tubes The design of the Tubecore is based on the possibility to replace the tubes. As a user, you can choose between a few types: 6N1P-EW (6N3P-EW) – standard set of tubes, “standard” IGS compression, 6BC8/6BZ8 – tight, transparent, punchy compression, 6386 – legendary compression, by famous twin triode, 5670 – deep and dark tube compression. The User’s Manual describes in detail how to replace tubes, so it is quick and straightforward. The quality Every single TUBECORE is hand made with high quality, matched components (1% metal film resistors, Wima caps). It is equipped with 6N1P-EW (6N3P-EW) NOS tubes and individually calibrated to give you the unique and unspoiled experience of one of the best vari-mu compressors in history. It is equipped with IGS Custom Made audio transformers.
