Stereo Vacuum Tube Optical Compressor. Made in USA. Very awesome!
* missing 5 knobs*. But recently serviced and all working sweet! True bypass for each channel using mechanical relays. Swedish Luhndal transformers at both the input and output of both channels. Switchable electroluminescent, LED or incandescent lamps for distinct and unique compressions. Dual mono or stereo with the ability to assign different compressions on each channel. Link mode to bridge channels 1 and 2. Each channel fully independent when Link mode set to off. Input and output gain controls. High quality detented potentiometers to ease recall of settings. Switchable squash mode for additional high frequency compression in EL mode. Switchable attack mode for slower attack in incandescent mode.
