The GT-80DSP Rear Panel:
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-80DSP was purchased outside ot the United States, see the unit's rear panel for its power rat¬
ing and follow the above guidelines.
27: FUSE: This protects the amplifier against damages caused from a faulty AC power source or other problems.
It the fuse blows, replace it ONLY with the same size and type 2.5A 120V sb-blow fuse. If the fuse blows repeat¬
edly check the AC source if rt's okay, contact your Crate dealer for service information.
28: EXTERNAL SPEAKER: Allows you to connect the output of the GT-80DSP to an external speaker, placing
it in series with tho 12' speaker inside Ihe amplifier. Since this is a series connection, there is no chance of dam¬
aging the amplifier wilh too small of an impedance load. However, keep in mind that by adding speakers you
raise the total impedance, which reduces the efficiency of the amplifier, thus bringing down the overall volume
level.
29: CHANNEL SELECT FOOTSWITCH: A dual footswitch can be plugged in here to give you remote control for
the selection of the Lead,Rhythm 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 FS-60), or a three-way toot-
switch (such as the Crate FS-80) 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 Digi¬
tal Sound Processing Mode tor all channels. The footswitch offers you a choice of Iv/o Mode settings per chan¬
nel: presetting cne of the choices to "bypass" gives you the traditbnal "crVoff" 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-80DSP's
internal power amplifier. Ihe 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, am¬
plifier. mixing console or recorder. Connect the Line Out jack to ihe INPUT of the device using a shielded cable
with mono 1/4" phone plugs. This sends a line-level signal OUT from the GT-80DSP. The Line Out jack is Post-
Master EO and Post-Master Level, therefore its tone and output level are governed by the settings of the amplifi¬
ers controls. The Line Out jack is an unbalanced mono 1/4' type.
