28.Footswitch Jack: Use this jack to
connect the BVFS4 four-button footswitch to
the amplifier. This allows you to switch
channels and turn the effects loop on and
off - by remote foot control. Connect one
end of the supplied footswitch cable* to
this jack, the other end to the footswitch.
29.Speaker Output Jacks: Use these
jacks to connect your speaker cabinet(s) to
the amplifier. The wiring for the Speakon
®
jacks is Pin 1+ = hot, Pin 1– = ground.
All six Speaker Output jacks are wired in
parallel, which lets you connect the amp to
a bunch of cabinets.
The minimum gauge of the wiring used for
these connecting cables should be 16GA!
30.Impedance Switch: Use this switch to
match the amplifier to the total impedance
of your speaker cabinets. Use the following

capable of potentially damaging certain
equipment. Make sure the Slave Out Level
control is all the way down before connect-
ing anything to the Slave Out jack. Then
slowly increase the Level control!
Never use the Slave Out if the
amplifier is not connected to a
speaker cabinet!
