WORKINGMAN’S 2004 • 7
One unique feature of the Return Jack is the ability to practice along with pre-recorded music. Insert a sound source into the
Return jack (make sure it is a mono source). Use the Effects Blend control to mix the level of the recorded music with your instru-
ment's level. The combined signal will be heard through your speakers, headphones, or both. The send jack is not used.
Please Note: Inserting a plug into the Return 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.
SPEAKER JACKS
Use an unshielded 2-conductor cable (NOT A GUITAR CORD!) to connect any speakers to your Workingman's . Use a high quality,
heavy gauge cable of at least 18 gauge (the lower the gauge, the heavier the cable). The total impedance of the speakers should
be 4 Ohms or greater. This means you can use one 4 ohm cabinet, two 8 ohm cabinets or four 16 ohm cabinets.
RECOMMENDED SPEAKER ENCLOSURES FROM SWR INCLUDE:
Any two of the following 8 ohm enclosures:
Workingman's 2x10T, Workingman's 4x10T, Workingman's 1x15T, Goliath III, Son Of Bertha, Big Ben Subwoofer and Goliath Jr. III (8
ohm version).
Any one of the following 4 ohm enclosures:
Big Bertha, Goliath Senior, Henry 8x8, Triad I or Goliath Jr. III (4 ohm version).
SPEAKER FUSE
The speaker fuse is provided to protect the power amplifier from a fault in the speaker cable or the speakers themselves. It can
also open (blow) if an impedance less than 4 ohms is used or in the unlikely event of a power amp failure. Size and rating of the
fuse is 3AG, 6 AMP FAST BLO. Do not defeat the purpose of this feature by using a higher rated fuse.
A/C LINE FUSE
This fuse is provided to protect the internal electronics against power surges, etc. It also protects the unit against
itself should one of the internal components fail. If this fuse should open, replace it with the same type of fuse
and rating. Do not defeat the purpose of this feature by using a higher rated fuse as it can void your warranty.
Proper rating of the fuse is as follows:
United States (120V): 3AG 4 amp, slo-blo
Europe (230V-240V): 3AG 2 amp slo-blo
A/C LINE CORD RECEPTACLE
Accepts a standard A/C power cable (supplied with the Workingman's in the United States), used with almost all current musical,
professional and household electronic devices. We recommend taking great care when packing up. Put the cable in your instru-
ment case, accessory case, etc. If it does become misplaced, replacement will be easy at almost any appliance store, super mar-
ket or the like.
Please Note: the rating for this cable is 3-conductor, 10 amperes. This is a rating of the current capacity of the cable, desig-
nated for higher power-drawing devices like amplifiers. If replacement is necessary, or if you wish to buy a longer cable, look for
the rating on the cable and be sure it is at least 10 amps.
