GAIN 1 and GAIN 2 knobs

These knobs adjust the analog gain of the input signal (before the A/D con-

verters). Adjust them so the LEDs light as described on the previous page.

Note: The XD-2 detects whether an XLR or 1/4" plug is connected

to the input jack, and it adjusts the preamp stage accordingly.

Microphones must use the XLR inputs; line-level and instrument-

level sources must use the 1/4" inputs.

48 V button

Push this button in if you are using a microphone that requires 48 VDC phan-

tom power. This applies phantom power to pins 2 and 3 of both XLR inputs

simultaneously. It has no effect on the 1/4" inputs.

Note: There are just a few microphones (mostly ribbons) that can

be damaged by phantom power. Consult your mic's manual to see if

it needs it or not. If it does need it, always turn off phantom power

before connecting or disconnecting your microphone.

MIX knob

This knob adjusts the signal going to your monitors, headphones and SPDIF

output. It allows you to choose a blend of the direct input signal post DSP,

and the USB signal coming from your computer. The knob has two extreme

settings: DIR and USB.

DIR: The input signal passes through the HP/LP ﬁ lters, DSP modules, and

output level controls, and is sent out to your monitors, headphones, and

SPDIF output. If you have the MIX knob set all the way to DIR, you will

hear no playback from Tracktion or your other audio software.
