effected signal is sent out the left bay output jack.

INDEPENDENT EQ: In this mode, the EQ section is available as a completely independent 
module. The corresponding rear/right side XLR connectors are now active allowing you to use 
the EQ on any external souse while the preamp remains available on the left bay. In this mode,
