NOTE
: The frequency response of the Workingman's 2x10C is far greater than usually found in musical
instrument amplifiers (20 Hz to 40K Hz). This was engineered in order to give the bass player the same
punch and clarity on stage as found in the studio or concert P.A. systems. Therefore, it is doubly important
that you are aware of the impedance and power rating of the extension speakers that you intend to use,
and that they are compatible with the Workingman's 2x10C. Speakers that have been overdriven are easy
to detect and generally do not fall under a manufacturer's warranty.
EXTENSION SPEAKER OUTPUT JACKS
One 1/4" phone jack is provided for connection of an extension speaker to the Workingman's 2x10C. Only
SPEAKER CABLE of 18 gauge or heavier (the heavier the cable, the lower the gauge) should be used to
connect an extension speaker to your Workingman's 2x10C. Do not use shielded instrument cable in this
application, as this can result in intermittent power loss, cause your amp to oscillate and damage itself
and/or your speakers, and render the cable useless for any purpose.
Recommended SWR Speaker enclosures for use as an extension cabinet with the Workingman's 2x10C
include:
Workingman's 2x10T
Workingman's 1x15T
Workingman's 4x10T
Big Ben (1x18 sub)
SPEAKER FUSE
The speaker fuse is provided to protect your speakers in the unlikely event of a power amp failure or to
protect your power amplifier from incorrect speaker impedances or hookups. Size and rating of the fuse is
3AG, 10 amp, fast-blo. Do not defeat the purpose of this feature by using a higher rated fuse as it can
damage your amplifier and void your warranty.
The fuse can open as a result of a fault in the speaker cable, the speakers themselves, or the power amp
being sent well into clipping. With this in mind, it is wise to carry extra fuses at all times.
INTERNAL SPEAKER MODE SWITCH
Located on the small panel on the rear of the Workingman's 2x10C's speaker cabinet, this two-position switch
controls the signal sent from the power amplifier to the
internal speaker cabinet only
. When set to the
On
(top) position (default setting from the factory), the Workingman's 2x10C will operate normally and the sound
of your amplified bass will be heard from the internal speaker cabinet. When set to the
Off
(bottom) position,
the internal cabinet's signal will be defeated,
but any extension speaker connected will still be audible
. This
could be extremely useful if you wish to use the amplifier in your 2x10C in a head-only configuration, at which
point you could connect any speaker cabinets to the amplifier just so long as the resulting total impedance
was no lower than 4 ohms. This can also be useful for silent practicing (in conjunction with the Headphones
Jack, listed previously), or for defeating the audio while you re-patch cables or plug and unplug your
instrument. This switch will not affect the signal present at the various audio outputs (XLR Out, Effects Send,
Tuner Out).
In some ways, this switch is similar to the Speakers On/Off Switch on the front panel, but remember: the
Speakers On/Off Switch on the front panel will defeat
all
speakers connected to the amplifier, while the
Internal Speaker On/Off Switch will only defeat the
internal
speaker system. But since either one can defeat
the internal speaker system, they can override each other when set to the bottom position. Make sure that
both switches are in the "On" position if you want to hear sound from your internal speaker system.
