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 shor t 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 inter fering 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, inser t 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
