SPEAKER ON/OFF SWITCH
The top position labeled "ON" completes the circuit from your power amplifier to the speaker jacks located on the back panel. In
other words, in turns your speakers on (provided they are hooked up). The bottom position labeled "Speaker" (down) interrupts
this path and turns your speakers off. The "Speaker" (down) position allows you to: tune up silently; use headphones "only" with
speakers still plugged in; change or add speaker cabinets with the unit still on; silent turn-on or turn-off transients.
If no sound is coming from your speakers, check the position of this switch. If the switch is in the “ON” position, check the speaker
fuse, cables, etc.
Please Note: This switch does NOT affect the Headphone jack.
STEREO HEADPHONES JACK
By inserting a set of stereo headphones into this jack you will be able to monitor your sound or practice without disturbing your
neighbors. The headphone volume level is adjusted by the Master Volume. We suggest you begin with the Master Volume full off
(counter-clockwise), then slowly bring up the volume to the desired level. If you hear some distortion in your headphones that is not
present with the speakers on, turn down the volume as you are probably overdriving your headphones and could ruin them.
Any impedance headphones will work. However, optimum impedance is 75 ohms.
WARNING: DO NOT USE MONO HEADPHONES. USE STEREO HEADPHONES ONLY!
POWER SWITCH
Pressing the Power Switch to the ON position activates the Workingman's electronics as indicated by the switch itself illuminating
in red.
Please Note: Because of the tight regulation in the power supply, a transient (pop) may occur when turning the unit on or off .
This is normal and will not harm you speaker. If you wish to avoid this condition, turn the Speaker Switch to the "Stand By" position
before turning the unit on or off.
REAR PANEL FEATURES
EFFECTS LOOP
The Effects Loop is located POST EQ and PRE Master Volume in the signal path. The level appearing at the Send jack is controlled
by the Gain control on the front panel. If you are getting too hot a signal to the input of your effect, reduce the level of the Gain con-
trol and raise the level of your Master Volume control to retain similar overall volume levels. By using the Gain, Master Volume and
Effects Blend controls, optimum performance should be easily obtainable with any effects device.
The Effects Loop is designed as a "sidechain" (parallel) function similar to those found on mixing consoles. Use of the Effects
Loop should greatly reduce noise generated by effects devices (as compared to in-line effects loops). Additional features of this
type of loop can be found below under the Receive jack section.
SEND JACK
Run a shielded patch cable from the Send jack to the input of your effects device. This jack may be used as an additional line level
output, in which case its level is determined by the setting of the Gain control.
RETURN JACK
Run a shielded patch cable from the output of your effects device to the Return jack.
