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.

Super Redhead specifications

The SWR Sound Super Redhead is a standout choice for musicians seeking a powerful and portable bass amplifier. Known for its exceptional sound quality and rich tonal capabilities, this amplifier combines impressive engineering with high-end performance, making it a favorite among professional bass players.

One of the primary features of the Super Redhead is its 400-watt power output, which provides sufficient headroom for live performances and studio recordings. Its ability to deliver a robust low end and clear mids makes it suitable for various musical styles, from jazz and blues to rock and metal. The amplifier is equipped with a custom-designed speaker cabinet featuring a 1x15-inch driver, designed to maximize low-frequency response while ensuring clarity across the entire frequency spectrum.

Another notable characteristic of the Super Redhead is its built-in 4-band EQ. This equalization system allows musicians to tailor their sound precisely to their liking, offering control over bass, low mid, high mid, and treble frequencies. The presence of a contour knob also enables players to shape their tone effortlessly, producing everything from a punchy slap sound to a smooth, rounded tone.

The Super Redhead incorporates SWR’s patented "tube compression" circuitry, which provides a warmth reminiscent of vintage tube amplifiers. This technology enhances sustain and articulation, resulting in a tonal depth that players appreciate. Additionally, the amplifier features a balanced XLR output for direct recording or PA integration, preserving tonal integrity in any setting.

Portability is another major appeal of the SWR Sound Super Redhead. Weighing in at just under 50 pounds, it remains manageable for gigging musicians. Its rugged construction ensures durability while the stylish design makes it visually appealing on stage.

Overall, the SWR Sound Super Redhead stands out for its innovative technologies, powerful sound generation, and versatility. Musicians looking for a reliable, high-performance bass amplifier will find that the Super Redhead not only meets but often exceeds their expectations. Whether in the studio or on stage, this amplifier has proven itself to be an essential tool for bassists who demand the best in sound quality and performance.
