1: INPUT: Use this jack to connect your guitar to
the amplifier by means of a shielded instrument
cable.
SOLO CHANNEL: A high gain channel giving you
sounds from a slight edge to serious overdrive.
2: GAIN: Use this control to adjust the amount of
distortion for the Solo channel.
3: LEVEL: Use this control to adjust the output
level of the Solo channel.
4: SOLO/CLEAN: Use this switch to select the
Solo or Clean channel. With the switch in the out
position, the Clean channel is selected. When the
switch is depressed, the Solo channel is selected.
CLEAN CHANNEL: A normal gain channel
designed to give you crystal clear sounds to medi-
um distortion.
5: VOL: Use this control to adjust the output level
of the Clean channel.
6: LOW: Use this control to adjust the low fre-
quency level of the amplifier.
7: MID: Use this control to adjust the midrange fre-
quency level of the amplifier.
8: HIGH: Use this control to adjust the high fre-
quency level of the amplifier.
9. DSP: Use this control to select one of the 16
built-in digital effects. The effects are discribed in
the table to the right.
10: CD INPUT: Use these RCA jacks to connect
the output from a CD player or tape deck to the
amplifier. The signal at these jacks is combined
into a mono signal which is sent to the internal
power amp circuit. Use the CD or tape player's
output level control to adjust the signal for the
proper mix with your guitar.
11: HEADPHONES: Use this jack to connect
headphones to the amplifier. The internal speaker
is disconnected when headphones are used.
CAUTION: To avoid possible damage to your hear-
ing, do not use headphones for extended periods
of time at extremely loud levels.
12: SPEAKER: Use this jack to connect the
amplifier to an external speaker. The internal
speaker is disconnected when this jack is used.
The impedance of the external speaker must be 4
ohms or greater.
WARNING: Do not attempt to use headphones in
the Speaker jack! Permanent hearing damage
could result!
13: POWER: Use this switch to turn the amplifier
on (top of the switch depressed) and off (bottom of
the switch depressed). The switch illuminates
when the amplifier is turned on.
14: POWER CORD (rear panel, not shown):
The grounded power cord should only be plugged
into a grounded power outlet that meets all appli-
cable electrical codes and is compatible with the
voltage, power, and frequency requirements stat-
ed on the rear panel. Do not attempt to defeat
the safety ground connection.
