Two 500 series LA-2A style compressors from IGS Audio.

IGS Audio has announced their One LA 500 compressor for the 500 series market. The unit is a dual slot mono module with the original Teletronix audio path with tubes on both input and output. It's a simple but impressive looking unit with easily read and operated controls. The large VU meter is a definite plus. Anyone familiar with the LA-2A will be  right at home with this unit.

The Photon 500 is their other LA-2A based unit;

From the website:

"The PHOTON 500 is an optical compressor, based on technology from the 60's, first used in the UREI LA-2A limiter and later in the LA4. As homage to these legendary products, we packed this technology into a 500-series module. The PHOTON 500 uses an opto-coupler, which introduces negative feedback in the audio path, taking care of gain reduction. It also has an electronically balanced input with 2520 compatible op-amp in the gain stage and a Carnhill transformer balanced output."

 FEATURES:

• Peak Reduction: controls the gain of the side-chain circuit,
• Hard wire Bypass,
• Ratio: 2:1, 4:1, 12:1,
• Sidechain Hi-Pass filter: Flat, 60, 120Hz,
• London/New York: Advanced compression curve modeling, like SLAM.
• Output: 12-pole stepped makeup gain.
