TREBLE CONTROL
The Treble control is a shelving-type tone control that cuts or boosts the high frequencies. Starting from mid-position, turning
the Treble control counter-clockwise cuts the high frequencies; turning the control clockwise boosts the high frequencies.
PULL TRANSPARENCY FUNCTION
In the normal (in) position, the shelving point of the Treble control is approximately 2kHz. By pulling the control to the "out" posi-
tion, the shelving point is changed to 4kHz, which essentially allows you to control the output of the tweeter (as the Super
Redhead's internal speaker complement is crossed over at 4kHz). The end result should be a clearer, more "transparent"
sound.
MASTER VOLUME CONTROL
The Master Volume control adjusts the signal level going to the power amplifier, the Effects Send jack, and the Record Out sec-
tion when set in the "Line" mode. The Master Volume does not control the level of the Record Out section when set in the
"Direct" mode. If the Power Amp Clip LED lights, turn down the Master Volume to correct the overload condition.
The Power Amp Clip LED will light when the internal power amp reaches clipping (runs out of headroom). Although this will not
harm the electronics in the Super Redhead, continual clipping of the power amp section will shorten the life of the internal
speakers and may damage them. Turn down the Master Volume to correct the situation. Speaker damage due to continuous
clipping of the power amp section is not covered under warranty.
RECORD/LINE OUTS
Unbalanced Output
The Unbalanced Out can be patched into any unbalanced input on tape decks, mixing consoles, etc. The signal at the
Unbalanced Out corresponds to the position of the Line/Direct switch. In the Line position, the level is adjusted by the XLR Pad
and all front panel controls are functional (i.e., affect the sound and level). In the "Direct" position, the level is adjusted by the
XLR Pad and the front panel controls do not affect the signal. Output impedance of the Unbalanced Out is 1.5kohms.
Balanced XLR Output
The Balanced XLR Out is a true balanced output and its level is set by the XLR Pad. The signal appearing at the XLR out is
determined by the position of the Line/Direct switch. In the "Line" position, 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 pos-
sible, 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 possibly 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 rais-
es these levels. If you are in the "Line" position and change the Gain level, this will also affect the output level of the record out-
puts. You may readjust the record level if necessary with the XLR Pad without affecting any other function.
