SWR Sound 2X10C - Manual (Page 13)

WORKINGMAN’S 2X10C • 13
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 speak-
ers 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 oscil-
late 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 clip-
ping. 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 inter-
nal speaker system. But since either one can defeat the internal speaker system, they can override each other when set to the bot-
tom position. Make sure that both switches are in the "On" position if you want to hear sound from your internal speaker system.
NOTE: One last time − if the volume on your instrument is up, and your Gain and Master Volume controls are up, and especially if
you're seeing the Preamp Clip and Limiter Active LED's illuminate while you're playing…and you can't understand why you're not get-
ting any audible output from the Workingman's 2x10C, check the position of this switch!
