Yamaha GC2020B II Stereo Compressor / Limiter, 1U rackmount, vintage analogue- made in japan stereo outboard compressor by yamaha from the 80s. Really great sounding compressor. Much better than a plugin. Analog mojo for lifeless digital recordings. Works with audio interfaces into the daw. Can saturate if input knob is driven. Awesome unit made in japan by yamaha in their prime. In absolute perfect working order. Works flawlessly. Will be packaged very safely. Great as well for running a mix through it for analog mixing glue.- This dual channel unit from Yamaha offers all the facilities that you might expect from a fully professional unit including a low level expander gate. ***Technical=The 2020 has balanced inputs via XLR and jacks and balanced output via XLR and separate unbalanced outputs via jack. Levels are switchable, per channel, between -20 and +4 dBm to allow matching with your chosen operating levels. The detector circuit is routed via in/out jacks on the rear panel. These are normally linked with a shorting loop but external devices can be patched here to EQ the sidechain or to create ducking effects. This is quite a rare feature on compressors in this price range. *Condition=In excellent used condition. All knobs & switches are original and in good order. There are a few minor scratches on the case, and a couple of tiny marks at the mounting holes, but overall it's exceptionally clean for a vintage device
