Better sound quality for cleaner recordings

Stereo pairs A and B each have dedicated level controls with signal indication and possible clipping warnings for the line input you are sending to.
Channel A is equipped with 6.3mm (¼”) balanced jack outputs to minimize noise and ensure maximum quality when delivering to the sound system.
Channel B outputs through a 3.5mm (⅛”) stereo jack, which can also serve as an additional headphone output.
The dedicated headphone output provides high output power and includes a selection switch for listening to either A or B channels.

Smart signal distribution

The normalization of inputs makes it easier to distribute signals to some or all of the outputs.
The MIX switch can blend Channel B into Channel A in stereo, opening up the module for several useful performance scenarios, such as pre-listening or simple stereo mixing.
