Connecting Outputs
Connect the analog audio outputs from the
LEFT OUT
and
RIGHT OUT
connectors to the inputs
of the desired analog destination device. Please note:
•
Balanced outputs are taken from pins 2 (
+
) and 3 (-) with pin 1 and the shell grounded.
•
Unbalanced outputs are taken from pin 2 with pin 1 and the shell grounded.
CAUTION
Do not connect pin 3 to the low (grounded) side of an unbalanced load.
See the “
DAC-24 Operation
” section below for instructions on adjusting level for conditions other
than
4 dBu reference with 20 dB headroom.
DAC-24 Operation
This section provides instructions for using the gain controls, aligning outputs, and adjusting the
headphone monitor.
Using the Gain Controls
For setting left and right output levels, each output has its own level adjustment on the front
panel. Outputs are factory-set for +4 dBu at -20 dBFS. Other levels can be set by using the
following alignment procedure:
To align the left and right analog outputs:
1. Connect a reference digital tone generator to the DAC-24’s
AES IN
connector.
2. Connect analog VU meters to the
LEFT OUT
and
RIGHT OUT
connectors.
3. Turn on the digital reference tone, and while metering the analog output levels, adjust the
associated
L
and
R
trimmers for the desired output level.
Using the Headphone Monitor
The analog outputs may be monitored with a pair of stereo headphones plugged into the
headphone jack. Best results are obtained with a headphone impedance of 20-50
Ω
. Use the
associated stereo
VOLUME
control to set a comfortable listening level.
