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.

  • tubes powered by 250V DC,
  • JJ 12AX7 input and RFT 12AU7 output tubes,
  • Sowter input transformer,
  • Edcor output transformer,
  • OEP sidechain transformer,
  • T4B replaceable photocell,
  • Power consumption: max 180mA per slot,
  • Input impedance: 10k Ohm,
  • Maximum output: +21dBU,
  • Amplification: 36dB,
  • Gain reduction: 36dB,
  • Frequency response: 20Hz – 20kHz, +/-0.1 dB,
  • Potentiometers manipulators,
  • Hard wire bypass,
  • Compressor/Limiter mode,
  • Large VU meter,
  • 3 years warranty,
  • Shipping weight: 3kg.

Price: 725 EUR/$994 USD



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.

SPECIFICATIONS:



  • 500-series module, 
  • Input impedance: 10kOhm, 
  • Max input level: +24 dBu,
  • Output impedance: 600Ω by Carnhill,
  • Maximum Output Level: +32 dBu,
  • Total Harmonic Distortion: max 0.5%,
  • Frequency response: +/- 0.2 dB 8Hz to 20kHz,
  • Gain: 30dB,
  • HPF: Off, 60Hz, 120Hz,
  • Signal to noise ratio: more than 99 dB,
  • Power supply: +/- 16V,
  • Power consumption: 110mA,
  • Dimensions: 133x37x180mm,
  • Weight: 700g,
  • 3 year warranty.
