8 • WORKINGMAN’S 8004 T/O/P
Effects Blend Control
The Effects Blend control “blends” the signal sent from your instrument with the signal coming from your
effects unit when used in the Effects Loop of the Workingman’s 8004. With the Effects Blend fully
counter-clockwise (“DRY”), no signal from your external effects unit will be heard. As you turn this control
clockwise, more of the effect can be heard in the overall sound. When the Effects Blend control is set fully
clockwise (“WET”), no true or unaffected signal is heard other than what your external effects unit pro-
vides. If your external effects unit has a similar control, adjust it to the fully clockwise (“Wet”) position.
This will avoid any possible phasing problems.
The Effects Blend circuit is similar to that used on recording consoles with the effects loop on a “side
chain” to the normal circuit. Unless the control is set to the full wet position, you will always get the full
sound of your instrument AND get the diversity an effects unit offers. This circuit is also effective in reduc-
ing noise generated by effects units because it is located after the gain stages in the preamp.
The Effects Blend control functions only when the Effects Loop is being used. It is activated when a 1/4"
phone plug is inser ted into the Effects Receive jack. (For more information, please see the heading titled
“Effects Loop” in the “Rear Panel Features” section later in this guide.)
Master (Volume) Control
The Master (meaning “Master Volume”) control adjusts the level being sent to the power amplifier in your
Workingman’s 8004—it controls the overall volume of the unit. Turning the control counter-clockwise
reduces the overall level, while turning the control clockwise boosts the overall level.
Note:
In most cases, the Master control does not affect the level present at the various output
jacks on the rear panel—it only affects the level being sent to the power amplifier, and subsequent-
ly, your speaker outputs only. There is one exception, however: the Preamp Out jack will be affect-
ed by the Master control. Also, losses caused by external effects units can be recovered by
increasing the Master control.
Speaker On/Off Switch
Setting the Speaker On/Off switch up to the “On” position allows the signal from the amplifier to be heard
through any speaker enclosure(s) connected to the Speaker Output section of the Workingman’s 8004.
Setting the Speaker On/Off switch down to the “Off” position disables the speaker output section. This
feature allows you to:
1. Use the Balanced (XLR) Output without using the internal speakers. This is especially useful in
recording when you are “miking” the speakers and only a direct signal is required for the moment.
2. Tune up without making sound onstage (and inter fering with other band members) while using the
Tuner Out feature.
3. Defeat the “pop” you sometimes get when changing and/or unplugging instruments from the unit
(especially if you sometimes forget to disconnect your instrument cable from the amplifier before discon-
necting it from your bass, something that’s always a good idea).
4. Defeat the “pop” present upon powering up the unit (though it causes no harm to the unit and/or
your speakers).
Note:
If you do not hear any sound when you plug in and your system is properly connected, check
the position of this switch!
Power On/Off Switch
This switch turns the complete unit on or off. Setting the switch upwards to the “On” position turns on the
unit, and the switch itself will illuminate in red. Setting the switch downward to the “Power” position will
turn the unit off, and the red light inside the power switch will turn off as well.
