The TCS is a two-channel high performance compression system which features two types of compression per channel utilizing ART’s Dual Topology technology. On one hand you can choose from optical compression, like that in our Pro VLA, for that smooth transparent compression. On the other hand you might want to use a VCA based compression scheme for hard limiting. Both of these compression methods are underneath the hood of this single space rack unit. Taking it even one step further the TCS offers the breakthrough feature of stacking the VCA and the opto isolator for when you want that over the top compression, or a hard VCA limiter on your optical compressed channels. Going beyond the idea of just a two-channel compressor, ART decided to spice up the TCS with our famous V3™ technology. The TCS also offers the ability for the user to twist the V3 knob to a variety of settings that take some of the hassle out of compression, yet still allowing each setting to be tweaked to the material’s needs. The TCS has a long list of impressive features, including a Toroidal Transformer, XLR & 1/4” Inputs, front panel instrument input, Optical and VCA compression capabilities, side chain inserts, channel linking for when you are working on a stereo track, attack, release, threshold, and ratio knobs, de-essing, an expander/gate per channel, V3 control per channel, twin VU meters for measuring compression, twin LED input/output meter for ultra-precise level metering, and the ability to place a tube in the signal path to add some warmth to your signal.
