26: POWER CORD: Firmly plug the supplied, heavy-duty grounded power cord into this receptacle. When in use,
be sure this cord is properly plugged into a safely-wired, grounded 120 volt, 60 cycle AC power outlet. DO NOT
attempt to defeat the ground connection on this cable!
If your GT-80D was purchased outside of the United States, see the unit's rear panel for its power rating and
follow the above guidelines.
27: FUSE: This protects the amplifier against damages caused from a faulty AC power source or other problems.
If the fuse blows, replace it ONLY with the same size and type use. If the fuse blows repeatedly check the AC
source: if it's okay, contact your Crate dealer for service information.
28: EXTERNAL SPEAKER: Allows you to connect the output of the GT-80D to an external speaker, placing it in
series with the 12" speaker inside the amplifier. Since this is a series connection, there is no chance of damaging
the amplifier with too low an impedance load.
29: CHANNEL SELECT FOOTSWITCH: A dual footswitch can be plugged in here to give you remote control for
the selection of the Overdrive/Clean channels AND the Tube/Solid State preamp sections. When connected, the
footswitch overrides the front panel switches for these functions.
NOTE: This is a STEREO 1/4" jack: "ring" controls the preamp sections, "tip" controls channel selection, "sleeve"
is ground for both. Use only a stereo-plug equipped footswitch (such as the Crate CFP-2), or a three-way foot-
switch (such as the Crate CFP-3) to control Reverb as well - see #30.
30: REVERB FOOTSWITCH: A single footswitch can be plugged in here to give you remote control for the Digital
Sound Processing Mode for all channels. The footswitch offers you a choice of two Mode settings per channel:
presetting one of the choices to "bypass" gives you the traditional "on/off" control. For additional information please
see "Using the Mode control" on page 8.
31: EFFECTS LOOP LINE IN: Connecting an external signal processor, such as digital delay or echo, can be
accomplished through the Line In and Line Out jacks. Connect the OUTPUT of the external device to the Line In
jack using a shielded cable with mono 1/4" phone plugs. This sends the line-level signal IN to the GT-80D's inter-
nal power amplifier. The Line In jack is Post-Master EQ and Post-Master Level.
32: EFFECTS LOOP LINE OUT: This carries a pre-amplified, post-EQ signal to an external effects device, ampli-
fier, mixing console or recorder. Connect the Line Out jack to the INPUT of the device using a shielded cable with
mono 1/4" phone plugs. This sends a line-level signal OUT from the GT-80D. The Line Out jack is Post-Master EQ
and Post-Master Level, therefore its tone and output level are governed by the settings of the amplifiers controls.
The Line Out jack is an unbalanced mono 1/4" type.
