REAR PANEL:
22: AC LINE IN: This heavy-duty, grounded, three-wire
power cord is to be plugged into ONLY a safely-wired,
grounded 120 volt, 60 cycle AC power outlet. DO NOT
attempt to defeat the ground connection of this cable! If
your GX-60C was purchased outside of the United States,
see the unit’s rear panel for its power rating and follow the
above guidelines.
23,24: EXT. SPEAKERS: You may connect the outputs of
the GX-60C to your external speakers using these jacks.
When connecting speakers use a matched pair; that is,
two speakers with the same impedance to insure optimum
performance from the amplifier. Since these are series
connections to the internal speakers there is no chance of
damaging the amplifier with too small of an impedance
load. The left speaker jack (#24) carries the chorus signal
(when the chorus is on) while the right jack (#23) is “dry”
(without the chorus effect).
25: STEREO HEADPHONES: Plug a pair of stereo head-
phones here for private listening. When this jack is used
the internal speakers and the external speaker jacks are
disconnected.
26,27: STEREO EFFECTS LOOP: Connect the Send
jack (#27) to the input of your stereo effects device to send
a post-EQ, pre-chorus, pre-amplified signal for processing.
Connect the outputs of the effects device to the effects
Return jack (#26) to return the processed signal to the
amplifier. These jacks are stereo 1/4” phone jacks, wired
as follows:
Ring = right channel
Tip = left channel
Sleeve = ground
If your effects device has stereo input and output jacks,
use a pair of three-conductor stereo patch cords to con-
nect to it. If the device has separate left and right jacks, use
a pair of one-stereo-male to two-mono-female Y-adapters
to make the connections, as shown to the right.
28: CHORUS FOOTSWITCH: Plug a single footswitch
(such as the Crate CFP-1 or the “mono” plug of the Crate
CFP-3) here to control the Chorus/Expander. The
footswitch overrides the front panel on/off switch (#16);
selection between the Chorus and the Expander is still
controlled by the front panel selector switch (#17).
29: CHANNEL/SHAPE FOOTSWITCH: Plug a dual
footswitch (such as the Crate CFP-2 or the “stereo” plug of
the Crate CFP-3) here to control Channel Selection and
the Shape Active button. The footswitch overrides the front
panel switches (#4 and 8) and is wired as follows:
Ring = Shape
Tip = Channels
Sleeve = ground
Connecting to the Insert jack:
The Insert jack (#15) lets you patch external effects into the
amplifier just prior to its power amp stage. Use Crate’s
CYC6MS stereo-to-mono Y-cord or an adapter such as
Crate’s CA11Y and 2 1/4” mono signal cables to connect
to the effect as shown below.
WARNING: DO NOT attempt to use headphones in the
Speaker jacks! Permanent hearing damage could result!
