REAR PANEL FUNCTIONS
1. A/C INPUT- Connects the amplifier to A/C power via the power cord
supplied. Unless otherwise specified, your amplifier is designed to operate
on 120 volts A/C, 60 cycles.
2. FUSE- 3 AG Type, slow blow fuse. Refer to the legend below the fuse holder
for the proper fuse rating for your amplifier. (50 watt-2.5 amp /100 watt-
3.5 amp)
3. GROUND SWITCH- Normally left in the center (Off) position. If you
encounter excessive A/C hum or ground loop noise, try the switch in the
other 2 positions.
4. POWER SWITCH- Turns the power on.
5. SPEAKER OUTPUT JACKS- There are 3 speaker output jacks- 4,8 and 16 ohm.
NEVER OPERATE YOUR AMPLIFIER WITHOUT A PROPER SPEAKER
LOAD CONNECTED. Be sure to match the impedance of your cabinet with
the impedance (output) of the amplifier.
6 FOOTSWITCH JACK- Connect the foot switch assembly here to enable
remote switching of the lead/rhythm and bypass functions.
7. EFFECTS SEND- Use this jack to send the amplifiers signal to outboard effects.
8. EFFECTS RETURN- Use this jack to connect the output of your effects to the
amplifier.
9. EFFECTS LEVEL- Adjusts the return signal level. It also acts as a master
volume control. Do not set fully counter-clockwise, as this will shut off signal
to the output section, resulting in no output level. Normally this control
should be set at the 12 o'clock position.
10. LEAD/RHYTHM SWITCH- Selects either the clean or lead channel when
footswitch is not in use. This switch must be left in the "down" (rhythm)
position to enable footswitch function.
11
. "SOLO" OR "BOOST" LEVEL- Adjusts the amount of boost for either
channel when the boost function is selected from the footswitch.
This feature allows 2 seperate levels for each channel, allowing the user to
dial in just the right amount of volume increase for soloing, etc.
