IGS Audio ONE LA 500 is an opto-compressor, built for the 500 series format. 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).

ONE LA 500 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. It is not only for harmonically rich vocals and strings, but also for huge and beefy drums and bass instruments.

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.

Not the piece of gear you’re looking for?
