FRONT PANEL FEATURES
BALANCED DIRECT RECORD OUT
The Balanced XLR output is a true balanced output. No front panel controls affect its signal. The tone and
output level are controlled only by the instrument plugged into one of the input jacks. To use this feature,
run an XLR (Cannon) cable from the Balanced D.I. to the input of a tape machine, mixing console, etc.
This output is also suitable for sending a signal to a house mixer in live situations.
Wiring for the XLR connector is as follows: Pin 1 = ground, Pin 2 = +, Pin 3 = –. (American standard)
TO TUNER
The To Tuner send jack allows the user to connect their instrument tuner to the Workingman’s 12 with-
out having to unplug and go back and forth from amp to tuner to amp. Like the Balanced D.I.
output, this feature is isolated from the rest of the circuitry and no other controls other than your instru-
ment have an affect on this feature. Being on an isolated sidechain also avoids loading down of the
instrument, which can cause a loss in dynamic range.
To use this feature, plug in a shielded patch cord from this jack to the INPUT of your tuning device. Turn
the amp on and you're ready to go. If you don’t want to monitor your sound while tuning, turn down the
Master Volume control or position the selector switch on the back panel to the “headphones” (middle)
position.
INPUT JACKS
Two separate and independent input jacks are provided so that the best signal-to-noise ratio can be
obtained without overloading the preamp section. The Passive input has over twice the gain than that of
the Active input. Both inputs can be used simultaneously without affecting the volume or tone of the
other. One use of these inputs would be to plug your bass into the Passive input and practice along with
a drum machine by plugging it into the Active input. A more detailed explanation of these inputs follows.
Passive Input
This input can and should be used if your instrument has passive electronics (no built-in preamp). Some
pickups employ batteries for operation and will work perfectly using this input. Technically speaking, this
input should be used if your instrument has an output voltage of 1 volt RMS or LESS. Consult the owner’s
manual that came with your instrument or ask the manufacturer if you are unsure.
NOTE: Generally speaking, you should try the Passive input jack first. If you hear a small amount of
distortion and the Preamp Clip LED is not activated, try using the Active input jack. Some passive
