This is the first high voltage vacuum tube 500 Series module that is offered by IGS. It is powered with 250 V DC from an on-board voltage converter, so it can be plugged into any 500 Series rack equipped with a standard power supply.\u003c\/p\u003e  \u003cp\u003eEvery 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 TneA, 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.\u003c\/p\u003e  \u003cp\u003eThree audio transformers (Sowter and Edcor in 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.
