Speaker Cable - SWR Super Redhead Operating Instructions Manual

INTERNAL SPEAKER CABLE
If you intend to use the Super Redhead's internal speakers, make sure the speaker cable from the chassis to the input jack is
properly connected. Switching the internal speakers off via the Speaker On/Off switch on the front panel will not harm the
amplifier in any way.
EXTENSION SPEAKER JACK
The Extension Speaker jack is provided for connecting an external speaker enclosure. Adding an external speaker cabinet will
increase the overall volume of your system and give you a "fuller" sound. When using an external speaker, make sure the total
impedance of any external speaker enclosure is 8 ohms (the Super Redhead is designed to drive a minimum impedance of no
less than 2.6 ohms).
Recommended SWR extension speakers for the Super Redhead include the following models:
• SWR Goliath III (4x10) (8 ohm version)
• SWR Goliath Junior III (2x10) (8 ohm version)
• SWR Son of Bertha (1X15)
• SWR Big Ben Subwoofer (1x18)
• SWR Workingman's 4X10T
• SWR Workingman's 2X10T
• SWR Workingman's 1X15T
Note: The Speaker On/Off switch does not affect the Extension Speaker jack.

SPEAKER CABLE

For all speaker connections, we recommend the use of high quality speaker cable that is at least 18 gauge or heavier (the
lower the gauge, the heavier the cable).
Note: Do not use shielded instrument cable to connect an external speaker enclosure. Doing so can result in intermit-
tent power loss, cause your amplifier to oscillate and damage itself (and/or your speakers), and render the cable use-
less for any purpose.
SPEAKER AND HORN FUSES
These fuses are provided for protection of the Super Redhead's internal speakers and horn/tweeter in the unlikely event of a
power amp failure (or vice-versa). The fuses can also blow due to improper connections, shorted speaker cable, or playing
while connecting or disconnecting speaker cabinets.
Correct size and rating of the speaker fuse is 3AG, 10 amp, fast-blo.
Correct size and rating of the horn fuse is 3AG, 3 amp, fast-blo.
Note: Do not defeat the purpose of this feature by using a fuse with a higher rating.
LINE FUSE
The Line Fuse will open (blow) if an internal problem exists with the electronics or in the event of a power surge or high power
line transients.
Correct US size and rating: 3AG, 7 amp, slo-blo (for 120 volt operation).
Correct European size and rating: 20mm x 5mm, 4 amp, slo-blo (for 220/240 volt operation).
Note: Do not defeat the purpose of this feature by using a fuse with a higher rating.
