EFFECTS LOOP (for outboard effects devices)
As mentioned previously in the "Effects Blend Control" section of the manual, the Effects Blend circuit in your Workingman's 2x10C is
similar to that used on recording consoles, with the effects loop on a "side chain" to the normal circuit. Unless the Effects Blend con-
trol is set to the full "wet" position, you will always get the full sound of your instrument AND get the diversity an outboard effects unit
offers. Use of the effects loop will reduce the noise generated by outboard effects units (as compared to using the effect between
your instrument and the input jack, though many people use it in this fashion anyway). This is because the loop is after the preamp
gain stages.
The Effects Loop is compatible with most individual or multi-effect outboard effects devices. Many effects devices on the market
have input level adjustments. For instance, some units have a switch that you can set for either -20 dB or +4 dB. In all cases, these
should be set for 0 dB (if available) or +4 dB. The level going to your effect is controlled by the Gain control on the front panel.
NOTE: The Effects Loop is used in conjunction with the Effects Blend control on the front panel. When the Effects Blend Control is
in the full counter-clockwise ("DRY") position, no effects will be heard. This is normal.
CONNECTING AN OUTBOARD EFFECTS DEVICE TO THE WORKINGMAN'S 2X10C EFFECTS LOOP
Obtain two high-quality shielded patch cables, preferably as short as possible. Route them in the most direct way possible. (Running
patch cables over the top of the Workingman's 2x10C
− as with any amplifier − can induce hum in the cables and is not recommend-
ed.) Take one cable and connect it from the Effects Send jack on the Workingman's 2x10C to the input of your outboard effects
device. Take the second cable and connect it from the output of your outboard effects device to the Effects Return jack on your
Workingman's 2x10C. To set levels, follow the instructions as previously listed in the "Effects Blend Control" heading under "Front
Panel Features."
EFFECTS SEND
This jack's primary function is to send a post-EQ signal to an outboard effects device for use in the Workingman's 2x10C Effects
Loop. However, it can also be used as:
1. A line level output for use in conjunction with an additional (slave) power amp − such as SWR's Power 750.
2. An unbalanced output suitable for recording or live mixing board purposes.
The output impedance of the Effects Send jack is 100 Ohms.
EFFECTS RECEIVE
This jack's primary function is to complete the Effects Loop circuit by routing the post-outboard-effects device signal back into the
power amp of the Workingman's 2x10C, where it can be blended back in with the original signal by using the Effects Blend control on
the front panel. However, it can also be used as:
1. A power amp input jack. If, for some reason, you wished to bypass the entire front end and use the Workingman's 2x10C strict-
ly as a powered monitor, you could take the output of whatever line-level audio source you wished and connect it to this jack. Then,
set the Effects Blend control to the full clockwise ("WET") position. Use the Master control to set the overall level, and your
Workingman's 2x10C is now a powered speaker cabinet.
2. An input for pre-recorded music, for playing along and practicing purposes. To accomplish this, insert a CD player or other
sound source into the Effects Receive jack. (It must be a MONO 1/4" plug that goes into this input, so you'll have to use a
stereo-to-mono cable adapter of some kind.) You can adjust the level of recorded music versus the "live" sound of your instrument
by using both the Effects Blend control (the more clockwise the control, the more pre-recorded music signal you'll hear) and the
volume control of your CD (or other) audio source. The mixed sound will be heard through your speaker(s). Besides pre- recorded
music, this is also an excellent way to practice along with a drum machine.
Input impedance of the Receive jack is 27k Ohms minimum.
