SWR Sound Super Redhead Xlr Pad, GROUND/LIFT Switch, LINE/DIRECT Switch, MUTE/LIVE Switch

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.
