Rear Panel Features

Standard IEC Receptacle. The
1) AC Receptacle:
power cord plugs in here.
2) 500W Amp Only:
¼" speaker output jacks. Im-
pedances Lower than 4 Ohms should not be used.
Higher impedances such as 8 Ohms, 16 Ohms, or
No Load are acceptable. One 4 Ohm, or 8 Ohm, or
two 8 Ohm cabinets are okay. One 4 Ohm and one 8
Ohm together is not recommended. No damage will
result from operating the amplifi er with the speakers
disconnected.
3) Footswitch: ¼" jack for standard 2-pole latching
footswitch. Switches between Channels and activates
the Mute.
4) Tuner Out: Comes directly off of the input stage.
Unaffected by the Mute button or any of the preamp
functions.
5) Effects Return: Returns the Effects Loop signal
to the signal path in series with the preamp signal.
The preamp signal will be interrupted when the Return
jack is used.
6) Effects Send: Provides access to the preamp signal
for putting effects into the signal path. May also be used
to drive other amplifi ers. The signal to the power amp
is not interrupted when the send jack is used.

7) Ground/Lift:
connecting to equipment that is running on a
different ground system.
8) Balanced Direct Out:
low impedance output to run directly to the PA system
via a 3-pin XLR cable.
Takes the Direct Out signal from
9) Pre/Post EQ:
before or after the EQ section.
10) Direct Out Level:
the Direct Out signal.
11) Speakon Outputs:
Speakon output connectors. Pins 1+ and 1- send a
fullrange signal from the Main (Woofer) amplifi er.
Pins 2+ and 2- send a signal 5kHz and above from the
Horn amplifi er. Use a four-conductor Speakon cable
when connected to a GK Horn Bi-Amp compatible
speaker cabinet. Use a standard two-conductor
Speakon cable when connected to a non-GK cabinet
or if you're using a Speakon to ¼" adapter.
