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. For over 15 years, we here at SWR have been putting  
everything we know about bass into the SWR product line. We’ve earned a reputation for designing  
and manufacturing gear that has changed the way bassists hear themselves. That’s why you’ll find  
our bass amps, cabinets and combos on stages and in recording studios all over the world, and why  
you’ll hear SWR on countless recordings, spanning all genres of music.  
Originally introduced in 1988, the SWR Redhead was immediately recognized by discerning bassists  
as the premier bass combo amplifier for small gig/recording studio use. As the Redhead was the first  
of its kind (i.e., small and powerful with features geared toward the professional musician), it has  
inspired many imitations. In 1996, the Redhead was upgraded to include a host of additional fea-  
tures and renamed the Super Redhead. Upgrades included increased power output and power han-  
dling, the addition of an internal cooling fan, redesigned front and rear panels, a mute switch for the  
XLR Output, and a front ported speaker section.  
Inside this User Guide you’ll find specifications, features, and usage suggestions for your Super  
Redhead. New SWR user and seasoned user alike will benefit from reading through this brief but  
informative manual.  
Thanks for choosing the SWR Super Redhead.  
Sincerely,  
SWR

FRONT PANEL FEATURES  
TUNER INPUT  
The Tuner Input jack allows you to connect an instrument tuner and tune up without having to unplug  
and go back and forth from amp to tuner. This feature is totally isolated from the rest of the preamp  
and will function regardless of the settings on the front panel. Being isolated on a side chain avoids  
loading down of the instrument, which can result in a loss in dynamic range.  
To use this feature, connect a shielded patch cable from the Tuner Input jack to the input on your  
instrument tuner. Turn the amplifier on and you’re ready to go. If you do not want to monitor your  
sound during tuning, either turn down the Master Volume completely or turn the Speaker On/Off  
switch to the “Off” position.  
PASSIVE/ACTIVE INPUT JACK  
This input can and should be used if your instrument contains passive electronics (i.e., no built-in  
preamp). Some instrument pickups use batteries for operation and will work perfectly using the  
Passive/Active input. Generally speaking, this input should be used if your instrument puts out a  
maximum of 1 volt RMS or less. Consult the owners manual for the instrument or ask the manufac-  
turer if you are unsure.  
Note: If you hear a small amount of distortion and neither the Preamp Clip LED nor the Power  
Amp Clip LED are activated, try using the Active Input jack.  
If you would like to overdrive the first tube stage, this can be accomplished by using a preamp  
between your instrument and the Passive/Active input. To obtain optimum sound when trying this,  
make sure the Preamp clip LED is not activated. If this occurs, turn down your Gain control. The first  
preamp stage is not monitored by the Preamp clip circuit for this reason.  
ACTIVE INPUT  
The Active Input jack should be used with instruments that contain a built-in (on-board) preamp that  
put out a signal over 1 Volt RMS. Some really "hot" pickups installed in your instrument may find the  
Active input more compatible. Let your ears be the judge.  
Note: The input impedance of the Active Input jack is 82kohms. Using the Active Input with pas-  
sive instruments (active instruments will always employ a battery) may result in a loss of high-  
end transients. 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  
 
PREAMP CLIP LED  
The Preamp Clip LED will light whenever the preamp, tone section, or output buffer reach clipping  
(run out of headroom). This function does NOT monitor the first tube stage of the Passive/Active  
Input jack (see “Passive/Active Input” for more information). Since the Preamp Clip LED also moni-  
tors the tone section, radically boosting any of the tone controls can cause the LED to activate. If this  
occurs, turn down the Gain control.  
Note: Constant clipping will not harm the electronics in the Super Redhead, however, damage  
may result to the loudspeakers due to near-DC content present in a clipped waveform.  
GAIN CONTROL  
The Gain control adjusts the volume of the preamp section. After the tone controls, Aural Enhancer,  
etc., have been adjusted to your liking, the Gain control should be set to where the Preamp Clip LED  
barely flashes upon striking your loudest note; then adjust the Master Volume control to the desired  
volume level. Since the Gain control is similar to a “Pad,” a small amount of signal will be heard  
when the Gain control is rotated fully counter-clockwise. Utilizing these controls in this manner  
assures the user of maximum signal-to-noise ratio without distortion caused by the preamp circuits  
clipping.  
AURAL ENHANCER  
SWR’s Aural Enhancer was developed to bring out the fundamental low notes of the bass guitar,  
reduce certain frequencies that help mask the fundamentals, and enhance the high end transients.  
The resulting frequency response should be similar to that used for recording the bass in the studio.  
This effect becomes more radical as the control is turned to maximum. The result is a more “trans-  
parent” sound and is especially noticeable when using the thumb style technique (“slapping”) on the  
bass guitar.  
The Aural Enhancer can basically be described as a tone-shaping control, as it is a passive R/C net-  
work that alters the frequency response throughout the bass spectrum. This pre-shaping is “blended”  
into the original signal via the Aural Enhancer control. Exact frequencies affected are dependent on  
the characteristics of the instrument used.  
BASS CONTROL  
The Bass control employs a shelving-type circuit and boosts or cuts the bass response 15dB.  
Starting at mid-position (“center click”), turning the control counter-clockwise cuts the bass response;  
turning the control clockwise boosts the bass response.  
PULL TURBO FUNCTION  
Pulling the Bass control to the “out” position widens the bandwidth of the Bass Control to include fre-  
quencies down to 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.  
MID RANGE SECTION  
LEVEL CONTROL  
The Level control cuts or boosts the frequency set by the Frequency control a maximum of 15dB.  
Starting at mid-position (“center click”), turning the Level control counter-clockwise cuts the frequency  
set by the Frequency control; turning the Level control clockwise boosts the frequency. When the  
Level control is set at mid-position, turning the Frequency control will have no affect on the sound.  
4 • SUPER REDHEAD OWNER’S MANUAL  
 
To find the midrange area you are looking for:  
1. Set the Level control to the full boost or cut position.  
2. Rotate the Frequency control until the area you wish to boost or cut is found.  
3. Adjust the Level control to the amount of cut or boost desired.  
FREQUENCY CONTROL  
The Frequency control sets the area that is to be cut or boosted by the Level control. If the Level con-  
trol is set at mid-position, turning the Frequency control will have no affect.  
TIPS FOR USING THE MID RANGE CONTROLS  
If you need to “cut through” the band a little more, try boosting 200 to 400Hz. If you like a more  
transparent sound, try cutting 800Hz. The Midrange controls are especially useful in controlling fret-  
less basses and their inherent qualities.  
TREBLE CONTROL  
The Treble control is a shelving-type tone control that cuts or boosts the high frequencies. Starting  
from mid-position, turning the Treble control counter-clockwise cuts the high frequencies; turning the  
control clockwise boosts the high frequencies.  
PULL TRANSPARENCY FUNCTION  
In the normal (in) position, the shelving point of the Treble control is approximately 2kHz. By pulling  
the control to the “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.  
MASTER VOLUME CONTROL  
The Master Volume control adjusts the signal level going to the power amplifier, the Effects Send  
jack, and the Record Out section when set in the “Line” mode. The Master Volume does not control  
the level of the Record Out section when set in the “Direct” mode. If the Power Amp Clip LED lights,  
turn down the Master Volume to correct the overload condition.  
POWER AMP CLIP LED  
The Power Amp Clip LED will light when the internal power amp reaches clipping (runs out of head-  
room). Although this will not harm the electronics in the Super Redhead, continual clipping of the  
power amp section will shorten the life of the internal speakers and may damage them. Turn down  
the Master Volume to correct the situation. Speaker damage due to continuous clipping of the power  
amp section is not covered under warranty.  
RECORD/LINE OUTS  
Unbalanced Output  
The Unbalanced Out can be patched into any unbalanced input on tape decks, mixing consoles, etc.  
The signal at the Unbalanced Out corresponds to the position of the Line/Direct switch. In the Line  
position, the level is adjusted by the XLR Pad and all front panel controls are functional (i.e., affect  
the sound and level). In the “Direct” position, the level is adjusted by the XLR Pad and the front  
panel controls do not affect the signal. Output impedance of the Unbalanced Out is 1.5kohms.  
Balanced XLR Output  
The Balanced XLR Out is a true balanced output and its level is set by the XLR Pad. The signal  
appearing at the XLR out is determined by the position of the Line/Direct switch. In the “Line” posi-  
SUPER REDHEAD OWNER’S MANUAL • 5  
 
tion, all front panel controls are functional and the signal is essentially the same as that being sent  
to the internal power amplifier. If you are using an effect, this will also appear mixed in the signal  
when you are in the “Line” mode. In the “Direct” position, the Balanced Out becomes an active tube  
direct box. No front panel controls are functional and once again, the level is adjusted by the XLR  
Pad.  
When using the Balanced Out for recording, optimum results can be achieved by driving the tape  
deck direct. If this is not possible, any matching level can be achieved via the XLR Pad.  
A ground lift is built into the XLR Pad control. To lift the ground, pull the knob outward until it clicks.  
If a persistent hum exists after lifting the ground, there may be a problem with the AC wiring or possi-  
bly a dirty AC line. If this is the case, we suggest using an isolation transformer between the Super  
Redhead and the wall socket.  
Wiring for the XLR connector is as follows:  
Pin 1 = ground, Pin 2 = +, Pin 3 = – (American Standard)  
XLR PAD  
To pad or adjust the level of both the Balanced XLR and Unbalanced Outs, use the XLR Pad. Rotating  
the control clockwise raises these levels. If you are in the “Line” position and change the Gain level,  
this will also affect the output level of the record outputs. You may readjust the record level if neces-  
sary with the XLR Pad without affecting any other function.  
GROUND/LIFT SWITCH  
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.  
LINE/DIRECT SWITCH  
The Line/Direct switch gives the user the option of either a line signal (preamp out) or direct signal  
from the instrument. The direct signal is active and generally hotter than most active direct boxes.  
Both the line or direct signal can be adjusted with the XLR Pad.  
To use the Line/Direct switch, position the switch ito either “Line” or “Direct.” Make sure the switch  
is all the way to the left or right to avoid an intermittent signal.  
MUTE/LIVE SWITCH  
The Mute/Live switch affects both the balanced and unbalanced outputs of your Super Redhead.  
Normal setting for this switch is “Live,” so signal will be present at both outputs. In the “Mute” posi-  
tion, the signal is muted to both outputs. This is useful when changing instruments, as no “thud” will  
be heard [out of the outputs].  
Note: Turn-off transients appear at the balanced and unbalanced outs when turning off the  
amplifier. Therefore, it is recommended that the Mute/Live switch be set to “Mute” prior to pow-  
ering down your Super Readhead.  
EFFECTS BLEND CONTROL  
The Effects Blend control allows the user to mix the dry signal with the signal coming from an effect  
patched through the Effects Loop on the rear panel. The Effects Blend control functions only when  
the Effects Loop is being used. It is activated when a 1/4" phone plug is inserted into the Effects  
Receive jack.  
6 • SUPER REDHEAD OWNER’S MANUAL  
 
HEADPHONE JACK  
The Headphone jack allows the user to monitor the sound via the use of stereo headphones. To prac-  
tice without sound coming through the Super Redhead’s speakers, turn the Speaker On/Off switch to  
the “Off” position and connect headphones to the Headphone jack. Stereo headphones must be  
used in this jack, as mono headphones will short out one side.  
Since the headphone “amp” is actually a reduced signal from the power amp, the Headphone volume  
is controlled by the Master Volume control.  
SPEAKER ON/OFF SWITCH  
Setting the Speaker On/Off switch to the “On” position allows the speakers to function as normal.  
Turning the switch to the “Off” position cuts the signal off to the Super Redhead’s internal speakers.  
This feature does not affect the external speaker output jack.  
The Speaker On/Off switch allows the user to:  
1. Use the record out system without using the internal speakers. This is especially useful when  
only a direct signal is required.  
2. Practice in a quiet environment without disturbing your neighbors by using the Headphone  
jack.  
3. Tune up without interfering with other band members when using the Tuner Input jack.  
POWER ON/OFF SWITCH  
Setting the switch to the “On” position activates the electronics in the Super Redhead as indicated  
by the Power LED lighting.  
REAR PANEL FEATURES  
EFFECTS LOOP  
The Effects Loop accepts any line level effects unit. Many high quality effects on the market have  
input level adjustments, usually a switch that can be set for either –10dB or +4dB. In all cases,  
these should be set for either 0dB or +4dB. The level going to your effect is controlled by the Gain  
control. The Effects Loop is designed as a “side chain” and functions similarly to recording studio  
mixing consoles.  
Because the Effects Loop is after the preamp gain stages in the signal chain, use of the Effect Loop  
should greatly reduce any residual noise generated by your effects unit (as compared to using an  
effect “in line” between your instrument and the input to the Super Redhead).  
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” power amp.  
RECEIVE  
After connecting the send jack as described above, connect a shielded patch cable from the Receive  
jack to the output jack of your effects unit. The input impedance of the Receive jack is 27kohms mini-  
mum.  
A unique feature of the Receive jack is that you can practice along with pre-recorded music. To do  
this, insert a tape recorder or other sound source into the Receive jack (make sure it is a mono  
source). Using the Effects Blend control on the Super Redhead’s front panel, adjust the level of the  
outside source so that a good blend is achieved with the sound level of your instrument. The blended  
SUPER REDHEAD OWNER’S MANUAL • 7  
 
signal can be heard through the internal speakers or through the Headphone jack. This same proce-  
dure can be used for playing along with a drum machine, sequencer, etc.  
Note: Inserting a plug into the Receive jack activates the Effects Blend control. The Effects  
Blend control “receives” this command through the ground created when inserting a 1/4" plug  
into the Receive jack. Therefore, best results will only be obtained by using a mono phone plug.  
If you must use a stereo plug, connect it by pushing in to the first “click” only.  
If you are not hearing any effect through your speakers, check the position of the Effects Blend con-  
trol on the front panel.  
FAN ON/OFF SWITCH  
In the “On” position, the Fan On/Off switch activates the internal cooling fan when the internal  
heatsink reaches approximately 55 degrees C. The fan will shut off when the heatsink has cooled  
down to about 45 degrees C. This action is controlled by an internal thermal switch located on the  
heatsink.  
The “Off” (or Defeat) position prevents the cooling fan from being operational. SWR recommends that  
this position be used ONLY in situations where normal fan noise might be audible and therefore prob-  
lematic—such as when miking the internal speakers in a recording situation. If you decide to defeat  
the fan for extended periods of time, we recommend that you turn it back on and allow it to run  
between songs, sets, etc. This way, the fan will be doing its job and will extend the life of the internal  
components. Double check the position of this switch each time you use your Super Redhead.  
Continuous use of the Super Redhead at loud volumes without use of the fan can cause the power  
amp to overheat and possibly fail.  
Note: If you hear the fan operating after use, we recommend that you allow the fan to run until  
it turns itself off, prior to turning off the Power switch.  
HIGH FREQUENCY ATTENUATOR  
The High Frequency Attenuator adjusts the amount of high frequency heard through the horn/tweeter.  
Turning the Attenuator control clockwise increases the signal; turning the Attenuator control counter-  
clockwise decreases the signal. In the full counter-clockwise position, no signal will be heard through  
the horn/tweeter. Recommended position for the High Frequency Attenuator is anywhere between  
9:00 and 12:00 depending on your taste.  
Note: Any clipping or unwanted distortion will be accentuated through the horn/tweeter. We have  
found that players using an especially “hard” technique to strike the strings can cause the  
strings to come in contact with the bass’s pickup and result in sharp spikes. If the clip indicators  
are not lit and you hear distortion coming from the horn/tweeter, try playing a little “softer.” Also,  
if using a bass with active electronics, check the battery.  
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 exter-  
nal 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(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.  
8 • SUPER REDHEAD OWNER’S MANUAL  
 
Recommended SWR extension speakers for the Super Redhead include the following models:  
• SWR Goliath III (4x10)  
• 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 intermittent power loss, cause your amplifier to oscillate and damage itself (and/or  
your speakers), and render the cable useless 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: 3AG, 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.  
AC CONVENIENCE OUTLET  
Any electronic device that operates on 120 volts, 60Hz and draws less than 3 amps or 360 watts  
may be plugged into the convenience outlet. This outlet is especially useful for powering units housed  
in the internal rack space such as multi-effects or rack tuners.  
It should be noted that some appliances such as fluorescent lights can cause interferenceor noise to  
be induced in the Super Redhead.

SPECIAL FEATURES  
FRONT COVER/ANGLE STAND  
The Super Redhead's front cover was designed to serve two main purposes: to protect the electron-  
ics and speakers during transport, and to double as a stand. To use the cover as an angled stand,  
remove the cover and place it in the desired location (carpet side up). Next, remove the caster  
wheels from the bottom of the unit and place it carefully on the cover/angle stand. You now have an  
angled amplification system that still couples the low end to the floor. Since all things have their lim-  
its, we do not suggest using the cover/angle stand as a ramp.  
BUILT-IN RACK SPACE  
The single rack space directly below the Super Redhead’s chassis is included for your convenience  
and is designed to accept any standard single rack space unit (19" wide x 1.75" high).  
REMOVABLE CASTERS  
The Super Redhead comes with removable caster wheels for easy transportation. To remove the cast-  
er wheels, simply turn the unit on its side and pull them out from the caster sockets. This will be  
necessary if you plan to use the cover/angle stand during practice or performance.  
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).  
THE TOP  
Almost every musician we talked to told us that at some time or another they were going to end up  
sitting on the amp. With this in mind, we would like you to know that we spent a great deal of time  
and effort to remove all mounting screws, vents and other obstacles from the top of the combo and  
covered it with carpet just to make these times more comfortable for you. Enjoy.  
REGARDING COMBO AMPLIFIERS  
The SWR Super Redhead has been designed with a robust 350-watt power amp, capable of driving  
its own speaker complement as well as cleanly driving an extension cabinet. When used by itself, a  
large amount of headroom is available in the Super Redhead’s power amp, which provides two impor-  
tant benefits: 1) A cleaner signal and better sound; 2) A power amp that operates at lower tempera-  
ture, thereby prolonging component life.  
However, because “combo” amplifiers such as the Super Redhead are designed as “all-in-one,” self-  
contained units (i.e., incorporating both power and speaker sections), some players are under the  
impression that they should be able to turn all controls to maximum without fear of speaker damage,  
distortion, etc. This is simply not the case. The Super Redhead will not overpower its internal speak-  
er section when run properly and in accordance with the operating instructions in this manual.  
However, damage to the internal drivers may occur if the amplifier section is driven into clipping for  
long periods of time. Please be aware of this possibility and turn down your Master Volume control if  
you hear distortion or notice that the Power Amp Clip LED is constantly lighting during operation.
