REAR PANEL FEATURES (continued)
Please Note:
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
SPEAKER JACKS
Use an unshielded 2-conductor cable (NOT A GUITAR CORD!) to connect any speakers to your
Workingman's 4004. 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:
RECOMMENDED SPEAKER ENCLOSURES FROM SWR INCLUDE:
Workingman's 4X10T, Workingman's 1X15T, Goliath III, Son Of Bertha, and the Big Ben Subwoofer
(you can use any two of these as they are all 8 ohms).
You may use one of the following:
Big Bertha, Goliath Senior, Henry 8x8, Triad I (these are all 4 ohm enclosures, therefore, only one can be
used).
SPEAKER FUSE
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, 8AMP FAST BLO. Do not defeat
the purpose of this feature by using a higher rated fuse.
A/C LINE FUSE
A/C LINE FUSE
The line fuse can open (blow) due to power surges or high powerline transients. This fuse will also open in
the event of an electronics failure inside your amplifier.
Correct size and rating of the Line (Mains) fuse: 3AG, 5 amp slo-blow for 120V operation,
and 1 1/2 amp slo-blo for 240V operation. DO NOT REPLACE THIS FUSE WITH ONE OF A HIGHER RATING.
IT MAY VOID YOUR WARRANTY AND DAMAGE YOUR AMPLIFIERS ELECTRONICS.
A/C LINE CORD RECEPTACLE
A/C LINE CORD RECEPTACLE
Accepts a standard A/C power cable (supplied with the Workingman's 4004 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 instrument case, accessory case, etc. If it does become
misplaced, replacement will be easy at almost any appliance store, super market or the like.
Please Note:
Please Note:
the rating for this cable is 3-conductor, 10 amperes. This is a rating of the current capacity
of the cable, designated 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.
