CONFIGURING THE XLR OUTPUTS:
The unit is factory configured to operate in Balanced output mode. The balanced signal comes
out PIN 2 and PIN 3 of the XLR outputs. PIN 1 is a ground connection for the cable shield. The
unit may be configured (via internal jumpers) to drive Unbalanced signals only, but the Balanced
configuration can be made to drive an Unbalanced load when using the proper
interconnecting cables as follows:
Alternative 1: Use PIN 2 for the signal and leave PIN 3 unconnected.
Alternative 2: Use PIN 3 for the signal and leave PIN 2 unconnected.
In both cases, PIN 1 is used for signal ground return. You may also tie a shield to PIN 1.
Note: Most XLR cable adaptors (such as a cable with XLR Female and a ¼ inch MONO plug)
work correctly as Balanced to Unbalanced converters.

OPERATION:
A. PLL SETTINGS:
Use Crystal or Narrow settings for 44.1, 48, 88.2 and 96KHz rates.
For stereo operation use CRYSTAL mode. When using multiple DA10 units use NARROW mode.
When a unit is locked to an input (LOCK lamp is ON), the received rate is indicated by a lamp.
Use WIDE for non standard frequencies between 30KHz and 200KHz.
When set to WIDE, all 4 lamps (44.1, 48, 88.2 and 96KHz) are ON.
Before turning the DA10 ON, select the PLL mode (Crystal, Narrow, or Wide).
Changing between Crystal and Narrow while the power is ON may take up to 50 seconds
to take full effect.
B. AVOIDING CLICKS:
The DA10 provides protection against "power ON clicks".
Switching between input sources (XLR, RCA or OPTICAL) and PLL modes (WIDE, NARROW
or CRYSTAL) during operation may cause unwanted clicks, especially when the signal is loud.
To avoid unwanted clicks when the unit is powered ON, it is advisable to reduce the volume down
when operating the INPUT switch, (XLR, RCA or OPTICAL) or the PLL switch (WIDE, NARROW
or CRYSTAL).
