LIMITER CIRCUIT
The Workingman’s 12 Limiter Circuit is a soft knee type limiter that prevents distortion of attack transients or peaks. The
Limiter can be used as an effect and is also helpful in preventing speaker damage. The circuit is located after (post) the mas-
ter volume and before (pre) the power amplifier; it is driven by the Master Volume control. Its threshold (starting point) is preset
by the factory so that the user can get maximum overall apparent volume without unduly overdriving the power amplifier.
LIMITER LED
The Limiter LED lights when your signal has reached the Limiter threshold, letting you know that the Limiter circuit has been
activated.
NOTE: No harm is being done to your amplifier when this LED lights or stays lit.
POWER SWITCH
Pressing the Power Switch to the ON position activates the Workingman's electronics as indicated by the red LED above the
switch.
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 con-
trolled 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 control 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.
Receive Jack
Run a shielded patch cable from the output of your effects device to the Receive jack.
One unique feature of the Receive jack is the ability to practice along with pre-recorded music. Insert a sound source into the
Receive jack (make sure it is a mono source). Use the Effects Blend control to mix the level of the recorded music with your
instrument’s level. The combined signal will be heard through the internal speakers or your headphones. The send jack is not
used.
NOTE: Inserting a plug into the Receive jack activates the Effects Blend control by receiving a “command” through the
ground created. Therefore, only a mono (2-conductor) phone plug should be used. If you have a stereo (3-conductor)
plug only, tie the ring and the sleeve (ground) together.
If you are not getting any “effect” through the speakers, check the position of the Effects Blend control.
