AC Receptacle: The detachable power cord plugs in here.
Speaker: Power amp output to speaker cabinet. Delivers 500w into 4 Ohm loads. Lower
impedances such as 8 Ohms or 16 Ohms and no l
oad are acceptable. One 4 Ohm speaker and
one 8 Ohm speaker is not recommended. This unique speaker output allows you to use a ¼”
plug or the high current, twist-lock Speakon conn
ector.
Foot switch Input:
A foot switch is provided to engage Boost and Master B modes.
Tuner Output: This output comes directly off of the input stage and can be patched to a tuner
using a shielded patch cord. This output is unaffected by the Tuning Mute Feature.
Return: This input allows the signal from outboard effects devices to be inserted before the boost
section.
Send: This output allows signal from the preamp
to be fed to outboard effects devices from a point
after the EQ section.
Ground Lift: This switch disconnects the ground
of the balanced, XLR output to eliminate hum
and buzz when connecting to equipment that is running on a different ground system.
Pre/Post EQ Button: This button switches the direct out signal to be before or after the EQ.

Balanced Direct Out: This electronically balanced output allows a direct connection to a P.A.
system.
Headphone/Line out: When switched, this output allows the user to send a direct (unbalanced) line
out to devices with unbalanced inputs such as personal multitrack recorders. This connection requires
a shielded patch cord. Unswitched, this headphone jack can be used to monitor your playing with
headphones.
Headphone/Line out switch: This switch toggles the output from headphone to line out.
