WORKINGMAN'S 2X10C - FRONT PANEL FEATURES
BALANCED D.I. (XLR) OUTPUT
The Balanced XLR output is a true balanced output. No front panel controls affect its signal. The tone and output levels are controlled
only by the instrument plugged into one of the input jacks. To use this feature, run an XLR cable from the Balanced D.I. Output 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 American standard (as follows):
Pin 1 = ground, Pin 2 = +, Pin 3 = -
TUNER OUT
The Tuner Out function allows the user to plug their instrument tuner into this jack and "tune up" without having to unplug and go back
and forth from amp to tuner. This feature is totally isolated from the rest of the preamp and will function regardless of the settings on
the front panel. Being isolated on a side chain avoids loading down of the instrument, which can cause a loss in dynamic range.
To use this feature, connect a shielded patch cord from the Tuner Out jack on your Workingman's 2x10C to the input jack on your
tuner. Turn the amplifier on and you're ready to go. If you do not wish to monitor your sound during the tuning process, you may either
turn down the Master Volume, or set the Speakers On/Off switch to the down position.
INPUT JACKS
Both input jacks accept a standard 1/4" phone plug and both inputs can be used at the same time. Since the two inputs are totally
independent, no loss in volume or tone will occur by using two instruments simultaneously. However, the main applicational use for the
two separate input jacks is their difference in level, as the Passive/Active input has five times more gain than the Active input. In other
words, it's not necessarily intended as a "submixer" for two instruments, but no harm will come from having two instruments plugged
in at once. Please read below for more details.
PASSIVE/ACTIVE INPUT JACK
This input jack is designed to accommodate both "passive" instruments and most "active" instruments. A passive instrument has no
built-in preamp and does not use a battery, while an active bass utilizes a battery-operated preamp for gain, tone controls, or both.
The Passive/Active Input will work with all instruments having a maximum output of less than 1 volt RMS. Some active pickups such
as EMG, Bartolini, etc., use batteries for operation and will work perfectly using this input. Instruments made by MTD, Sadowsky,
Modulus, etc., have active electronics that are suited for use in the Passive/Active input.
Generally speaking, try this input first. If you hear a small amount of distortion and the preamp clip LED is not activated, try using the
Active input jack. If the Active input does not correct any audible distortion, check the battery in your bass.
ACTIVE INPUT JACK
The Active input jack should be used with instruments having a built-in (on board) preamp or other sound sources that will produce
output levels greater than 1 volt RMS. The number of bass manufacturers has increased significantly over the years, and it's impossi-
ble to try and keep track of them all. Generally, if you have very "hot" pickups and/or tone controls installed in your instrument, and
you use them to boost the level of your bass signal 10 dB or more, you may find the Active input more compatible. The best judge is
your own ears.
If you're using a keyboard or bass pedal with the Workingman's 2x10C, we have found the best choice to be the Active input.
NOTE: Using the Active input with passive basses (active instruments will always employ a battery) may result in a loss of high end
transients. Players who roll off their high end starting at about 2kHz, or prefer a "darker" sound, may find this input more to their lik-
ing.
If you hear some distortion with your active bass and are using the Active Input, make sure the preamp clip LED indicator is not
lighting. If the preamp stage is not being driven into clipping, replace the battery in your instrument.
