WORKINGMAN’S 8004 T/O/P – GETTING STARTED
Connecting Your Speaker Cabinets
The Workingman’s 8004 is a mono amplifier, which makes things fairly simple. Locate the “Speaker
Outputs” section on the rear of the amp. You will notice that there are four different speaker output jacks:
two 1/4" type and two Speakon type jacks. The Speakon jacks are preferable if your speaker cabinet is
equipped with Speakons as well; however, you can use any of the four available jacks to connect your
speaker(s) to the Workingman’s 8004.
Using One Speaker Cabinet
Using a speaker cable of 18 gauge or heavier (the heavier the cable, the lower the gauge), simply connect
any one of the Workingman’s 8004’s Speaker Output jacks to the input jacks of your speaker cabinet. If
your cabinet is a 4 ohm enclosure, the Workingman’s 8004 will deliver 750 watts into it. If your cabinet is
an 8 ohm enclosure, it will deliver 450 watts into it. This is a loud amplifier. Be sure to check the power
handling capabilities of your speaker cabinet before connection and operation.
Using Two Speaker Cabinets
Using a speaker cable of 18 gauge or heavier (the heavier the cable, the lower the gauge), simply connect
any of the Workingman’s 8004’s Speaker Output jacks to the input jacks of your two speaker cabinets.
(You can use one 1/4" and one Speakon Output jack each if you wish; however, it is always best to use
speaker cables with similar type ends.) If the cabinets are the same impedance, the same amount of
power will be sent to each enclosure. If the cabinets are different impedances, more power will flow to the
cabinet with the lower impedance. Since the Workingman’s 8004 is a mono amplifier and individual cabi-
net levels cannot be adjusted, it is recommended that you use cabinets of the same impedance when
using more than one cabinet. If you use two 8 ohm cabinets—the two-cabinet setup recommended by
SWR—the resulting “total” impedance will be 4 ohms, and the Workingman’s 8004 will deliver 750 watts
spread across both cabinets. Needless to say, in all cases, be sure to check the power handling capabili-
ties and impedance of your speaker cabinet(s) before connection and operation.
Note: The minimum total impedance when operating the Workingman’s 8004 is 4 ohms. This means
you can safely use:
1) A single 8 ohm cabinet
2) A single 4 ohm cabinet
3) Two 8 ohm cabinets (total: 4 ohms)
More details are available in the “Speaker Outputs” section of this guide, and we strongly recommend that
you read the entire guide. However, this should be enough information to get you star ted.
