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, usu-
ally 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 record-
ing 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 minimum.
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 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 control on the front panel.
FAN ON/OFF SWITCH
With the Fan On/Off switch in the "On" position, the internal cooling fan will run at slow speed when the internal heatsink tem-
perature is below 85 degrees C and at high speed when the temperature is above 85 degrees C. The Fan On/Off switch
should be left in the "On" position for normal operation.
With the Fan On/Off switch in the "Off" position, the internal cooling fan will be off when the internal heatsink temperature is
below 85 degrees C and at high speed when the temperature is above 85 degrees C. SWR recommends that the "Off" posi-
tion be used ONLY in situations where fan noise might be audible and therefore problematic—such as when miking the internal
speakers in a recording situation.
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.
