SUPER REDHEAD OWNER’S MANUAL INTRODUCTION Congratulations on your purchase of an SWR Super Redhead professional bass amp combo. By choosing an SWR bass amplification system you have made a sound decision that could very well be the best of your life! Just a little humor there, but true nonetheless.

SIGNAL-TO-NOISE RATIO: –72 dB (<10 millivolts typical) EQUIVALENT INPUT NOISE: 9 microvolts POWER HANDLING: 350 watts RMS continuous program CROSSOVER (located in the Super Redhead’s chassis): Third order, 6dB roll off, 18dB Butterworth high pass, 4kHz turnover SPL: 105 dB (–3dB @ 45Hz and 15kHz)
Players who roll off their high end starting at about 2 or 3kHz may find this input more to their liking. If you hear distortion when using an active instrument in the Active Input jack, check your battery! Also, make sure that none of the clip indicators are lit. SUPER REDHEAD OWNER’S MANUAL • 3...

30Hz (low “B” on a 5-string bass). Since some of these notes can be felt more than heard, it is especially important to keep an eye on the preamp and power amp clip LEDs. Constant clipping of these frequencies can diminish the life of Super Redhead’s internal speakers or cause them to fail.

“out” position, the shelving point is changed to 4kHz, which essentially allows you to control the output of the tweeter (as the Super Redhead’s internal speaker complement is crossed over at 4kHz). The end result should be a clearer, more “transparent” sound.
When using the Balanced XLR out, this feature may help in eliminating ground loops between your Super Redhead and an external mixing board. Normal setting for this switch is in the “Ground” posi- tion. When switched to “Lift,” the ground (Pin 1 as noted above) is lifted. In some cases, this will eliminate unwanted hum.
SEND To use an effect in the Effects Loop of your Super Redhead, connect a shielded patch cable from the Send jack to the input of your effects unit. The output impedance of the Send jack is 100 ohms. This jack may also be used as a line level output for use in conjunction with an external “slave”...

When using an external speaker, make sure the total impedance of any external speaker enclosure(s) is no less than 4 ohms (the Super Redhead is designed to drive a minimum impedance of no less than 2 ohms). In most cases, we recommend the use of a single 8 ohm extension speaker.
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.
SPRING-LOADED RUBBER-GRIP HANDLES The handles on either side of the Super Redhead were chosen for their “rattle free” properties and the extra-thick rubber padded grips. The handle placement allows for near perfect balance (meaning the unit should not tilt forward or backward when carried).
