Solid state stereo line stage.

Direct coupled solid-state design. No capacitors in the signal path. 6 inputs + 1 tape loop. Each input consists of 1 set of balanced XLR + 1 set of single-ended RCA. Either the XLR or the RCA set can be active, but not both at the same time. 2 main outputs. Each output consists 1 set of balanced XLR + 1 set of single-ended RCA. All of them can be used simultaneously. Unity gain mode for integration with a surround sound preamp. This allows you to pass surround sound through the 2 main channels.
