D/A Conversion Using Digital Audio Source Clock
In this configuration, the 2192 is synchronized to the clock signal that is embedded within the digital
audio signal that is being converted to analog.
To perform D/A conversion using the digital audio source clock:
1. Connect the 2192 rear panel analog line outputs to the analog inputs of the destination
device (patch bay, mixer, DAW, etc).
2. Using an appropriate digital cable, connect the digital output of the external digital audio
source device to the desired 2192 rear panel digital input.
3. Set the 2192 Clock knob to specify the digital input that the digital audio source signal is
connected to (AES/SPDIF or ADAT). If the Clock knob is set to AES/SPDIF, use the AES/SPDIF
switch to specify AES or SPDIF.
4. If the digital source is AES/SPDIF, the Sample Rate Select knob has no effect. If the digital
source is ADAT, use the Sample Rate Select knob to select the appropriate S-MUX format.
(see page 6 for information on sample rate selection)
5. Set the 2192 Analog Outputs knob to the same digital setting as in step 3.
6. Set the digital audio source device to transmit digital audio. The source device must be set to
use its internal clock, or set to synchronize to an external clock master.
D/A conversion is performed only when the 2192 is locked (the external clock must be running)
and digital audio is present at the digital input. The Locked lamp glows green when the 2192 is
successfully synchronized to an external clock source.
