24. FUSE: The fuse protects the amplifier
from damage caused by a faulty AC power
source or other problems. If the fuse opens,
replace it with the same size and type. If
fuses continue to fail, check the AC source. If
the source is okay, refer to page 12 or con-
tact your Crate dealer for service information.
25. EXTENSION SPEAKER: Use this jack
to connect the amplifier to an external speak-
er cabinet. This jack is wired in series with
the internal speaker, which remains active
when an extension speaker is connected.
26. DSP FOOTSWITCH:
Use this jack to connect one of the footswitch
cables to the three-button footswitch (sup-
plied). This allows you to select between two
DSP presets for each of the three channels.
Additional information about the operation
of the footswitch is on
page 8.
27. CHANNEL
FOOTSWITCH: Use this
jack to connect one of
the footswitch cables
to the three-button foot-
switch (supplied). This
allows you to remotely
switch between the
Clean, High Gain, and
Overdrive channels.
Additional information
about the operation of
the footswitch is on
page 8. 28. INSERT: Use this jack to connect an
external signal processor to the amplifier. Use
Crate’s STP201, STP202, or STP203 stereo-
to-mono Y-cord or an adapter such as Crate’s
YPP117 and two 1/4" mono signal cables to
connect to the effect, as shown below.
29. POWER CORD (not shown): This
grounded power cord is to be plugged into
a grounded power outlet, wired to current
electrical codes and compatible with the
voltage, power, and frequency requirements
stated on the rear panel. Do not attempt to
defeat the safety ground connection!
30. ELECTRONIC TUNER (cabinet top)
The electronic tuner is active whenever the
amplifier is turned on, providing constant
“real-time” tuning. The row of red LEDs on
the left indicates which note is being tuned.
When a single LED is lit,
it represents the note
that appears just below
the LED. When two LEDs
are lit, it represents
the note that appears
between them in the
bottom row. The left
green LED indicates the
note is flat, and the right
green LED indicates the
note is sharp. The note
is properly tuned when
both LEDs are lit at the
same time.
