ONE LA 500

Classic LA2A in your 500 series rack!

 

Two knobs of happiness

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.

Using two ONE LA 500 as a stereo pair will allow you to use it as an excellent bus compressor!

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)

"No compromise device - all tubes are powered by 250V DC!"
