CONNECTING T
O THE INSERT JACK:
The Insert jack (#16) allows you
to patch an external effects
device into the amplifier prior to
its power amp stage. 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 the effect as shown in
the adjacent illustration.
16: INSERT: Use this jack to connect an external effects device to the amplifier. Use a stereo 1/4” male Y con-
nector: ring = send, tip = return, sleeve = ground. (Refer to the illustration at the bottom of page 5.)
17: EXTERNAL SPEAKER: Use this jack to connect an external speaker to the amplifier. This jack is wired in
series with the internal speaker(s) which remain active when an external speaker is connected.
18: POWER: Use this switch to turn the amplifier on (top of the switch depressed) and off (bottom of the
switch depressed). The switch is illuminated when the amplifier is on.
19: AC LINE CORD (rear panel, 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 require-
ments stated on the rear panel. Do not attempt to defeat the safety ground connection.
20: FUSE (rear panel, not shown): The fuse protects the amplifier from damages caused by a faulty AC
power source and/or other problems. If the fuse opens, replace it ONLY with the same size and type. If fuses
continue to fail, check the AC source – if the source is okay, contact your Crate dealer for service information.
21: CHANNEL SELECT / GAIN FOOTSWITCH JACK (rear panel, not shown): Use this jack to connect the 1/4”
stereo plug on the footswitch cable to the three-button footswitch (supplied). This allows you to remotely switch
between the Clean and Rhythm/Solo channels and between Rhythm Gain 1 and Solo Gain 2 of the Rhythm/Solo
channel.
22: REVERB FOOTSWITCH JACK (rear panel, not shown): Use this jack to connect the 1/4” mono plug on the
footswitch cable to the three-button footswitch (supplied). This allows you to remotely turn the DSP function on and
off.
