The 622 is a dual channel Logic Assisted expander/gate. It incorporates new, proprietary detection circuitry that provides the most reliable, accurate and stable operation of any gate. The unit has the ability to increase dynamic range, along with lowering the noise floor of any equipment, and uses the highest quality VCA's to assure that there will never be a click in the audio material during gate operation.

The 622 offers a high quality audio path, flexible high-Q key filters, key headphone outputs on the front panel, and remote controlled bypass relays. These features make the 622 the unit of choice for controlling audio leakage in stage and studio applications, manipulating external audio programs for voice-overs and automatic level changes, or reshaping any sound envelope.

The 622 will also help keep vocals clean, bass sounds tight and fat, or help in controlling feedback.
