The IGS Photon 500-Series Compressor 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 an homage to these legendary products, IGS packed this technology in a 500-series module for compressing instruments such as guitars, bass, synths and more.

The IGS Photon 500-Series Compressor uses an opto-coupler, which introduces negative feedback in the audio path, taking care of gain reduction, being the basics of all compression. The Photon has an electronically balanced input with 2520 compatible op-amp in the gain stage. The output is balanced by a Carnhill transformer.
