phantom power—+48V

48 volts DC is applied to pins 2 and 3 on the mic-input XLR con- nector. This option is used with condenser microphones and active direct boxes that require an external DC voltage (phantom power) in order to operate.

The 48V switch should not be engaged when using standard (dynamic) microphones, or other sources that do not use phantom power.

a

pad

The mic-input signal is attenuated by 20dB to prevent some signals (e.g. kick drum or lead vocal) from overloading the preamp stage.The pad is used to bring a hot mic-input signal down to a controllable level. The 20dB pad is not functional when the LINE switch is depressed.

If the channel peak	+
LED is illuminated,	+
first try lowering
the input gain control.

Only when this method is unsuccessful should the pad switch be engaged.

line

The input preamp circuit is set up to accept a mic-level signal. This signal is brought in via the XLR mic-input connector located on the rear panel.The 1/4" TRS input jack is disabled.

The input preamp circuit is set up to accept a line-level signal from either the XLR mic-input connector or the 1/4"TRS input jack,both locat- ed on the rear panel.

When a plug is inserted into the 1/4" TRS input jack, the XLR mic-input connector is disabled.

polarity reverse—ø

This feature is used for correcting or minimizing polarity and phase relat- ed errors. For example, occasionally a balanced input connection is reverse-wired before it gets to the mixing console. This can happen in microphones, or in snake line interfaces. By using the polarity reverse fea- ture, this type of error can be corrected.

polarity inverted

polarity not inverted

If the 48V phantom	+
power switch is

engaged, depressing this switch disconnects phantom power from the mic input XLR.

When similar signals	+
from different chan-

nels are combined, phase cancellations can occur.

Reversing the polarity of an input signal often corrects such phasing errors.
