D/A Using Digital Audio Source Clock
In this configuration, the 2192 is synchronized to the clock signal that is imbedded 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 analog outputs to the analog inputs of the destination device (mixer,
recorder, etc).
2. Connect the digital output of the external digital audio source device to the desired 2192
digital input using an appropriate digital cable.
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/EBU or S/PDIF.
4. If the digital source is ADAT, use the Sample Rate Select knob to select the appropriate S-MUX
format: 44.1 and 48 select standard 1x mode, 88.2 and 96 select 2x mode, and 176.4 and
192 select 4x mode. If the digital source is AES/SPDIF, the Sample Rate Select knob has no
effect.
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).
The Locked lamp glows green when the 2192 is successfully synchronized to an external clock
source.
