Setup screen continued
Note: The XD-2 follows the sample rate settings (44.1, or 48 kHz) and bit depth (16 or
24 bit) of Tracktion. To adjust the sample rate and/or bit depth, see the system settings
in Tracktion (under the "Settings" tab), or the system preferences in your audio software
application. If the sample clock is set to S/PDIF, the XD-2 will look for, and lock on to a
connected S/PDIF device operating at 44.1, or 48 kHz sampling rates.
USB Connection Established
This LED lights when the XD-2 is successfully connected to your computer. If you are having trouble,
one of the fi rst things to do is to check that this light is on.
Maximum Sample Rate Mode
This sets the maximum sample rates available to Tracktion. Select 48 kHz IN/OUT. For 88.2 or 96
kHz sample rates (available in a future upgrade), select 96 kHz IN if you are recording, and 96 kHz
OUT if you are playing back. At these faster sample rates, the XD-2 can record or play back high res-
olution audio, but it cannot record and playback at the same time. When making a change, the XD-2
will reset, and you have to restart Tracktion so it will recognize the XD-2 again.
Monitor Source
This allows you to switch the monitor output to STEREO or MONO. It does not affect the signal sent
via USB to your computer. In MONO, both input channels are panned to center, and appear in both
left and right outputs (monitor/phones/S/PDIF). In STEREO, channel 1 appears in the left output
and channel 2 appears in the right. MONO is useful when tracking only a single channel at a time, so
your gifted solos can appear in both speakers
Note: The MONO sound image should appear to come from a point directly between the
speakers. If the Bass decreases when MONO is selected, one speaker might be wired out-
of-phase. Check the speaker terminals match the amp terminals (red to red, black to black).
