BALANCED XLR OUT
The Balanced Out is a true balanced output and serves two functions. In the “Direct” position, the XLR is essentially an active tube direct box. The signal is taken directly from the input jacks. No controls on the front panel affect the sound, volume or content of the signal. In the “Line” position, ALL controls on the front panel (with the exception of the Effects Blend and Master Volume) function and affect the signal. Output level in the “Line” position is determined by both the Gain and XLR pad. When using this switch, make sure it is all the way to one side or the other and not in a “half way” position, as this could result in no output.
The “Line” position can be used for recording directly into a tape machine as well as going directly to the studio board. An external power amplifier with a balanced input can be driven in the "Line" mode.
Pin out for the XLR connector are as follows:
Pin 1 = Ground Pin 2 = + | Pin 3 = – |
The
XLR PAD AND GROUND LIFT
The XLR pad adjusts the level (volume) appearing at the XLR connector directly below in either the Line or Direct mode. Volume increases as the control is turned clockwise.
If you are in the “Line” position and change the Gain control on the front panel, the level will also change at the balanced output. You may readjust the XLR pad if necessary without affecting any other function.
A ground lift is provided for the record out XLR Output. It is built into the XLR Pad. With the knob on the XLR pad in the “In” position, the ground to pin one is engaged. Pulling the knob to the out or “Ground Lift” position will interrupt or defeat the ground on pin 1.
If a persistent hum exists after trying both positions of the ground lift, there is probably a
