Ground/Lift Switch - SWR Super Redhead Operating Instructions Manual

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" position. 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 to 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" position, 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 rec-
ommended that the Mute/Live switch be set to "Mute" prior to powering down your Super Redhead.
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.
HEADPHONE JACK
The Headphone jack allows the user to monitor the sound via the use of stereo headphones. To practice 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.
