DBX retailer 563X the silencer

Product Name: DBX retailer 563X the silencer
In good condition & working. The DBX 563x silencer is a great problem solver. It was made to reduce tape hiss for analog tape. It's a single ended noise reduction. The great thing retailer is, It has an instrument input, a line level input, a line level output marked as "High" and an instrument level output marked a "Low". It also has a bypass, a slider for noise reduction, instrument input volume, and a stereo input and switch for combining two units. It has an internal power supply and is half rack. The bypass is not hard wire. It cuts off the noise reduction if set.
