Using the 2192 for Transcoding (Converting Digital Formats)
The 2192 can transcode (convert) digital audio data between AES/EBU, S/PDIF, and ADAT optical
formats in real time. The transcoded digital audio input signal is output to all 2192 digital audio
outputs simultaneously.
Transcoding can be performed using any of the available clock sources. To hear analog audio during
transcoding, set the Analog Outputs knob to the digital audio source.
Transcoding can be performed using either the internal clock, the digital audio source clock, or an
external clock master. Each operation is detailed below and on the following pages.
Transcoding Using Internal Clock
In this configuration, the 2192 is the master system clock.
To perform transcoding using the internal clock:
1. Using the appropriate digital cable, connect the digital output from the external digital audio
source device to the desired 2192 digital input.
2.
Using the appropriate digital cable(s), connect the 2192 digital output(s) to the digital
input(s) on any external device(s) that will receive the transcoded digital audio signal.
3.
Set the 2192 Clock knob to Internal.
4.
Set the 2192 Sample Rate knob to match the sample rate of the digital audio source signal.
5.
Set the 2192 Digital Outputs knob to the digital audio source input (AES/SPDIF or ADAT). If the
Digital Outputs knob is set to AES/SPDIF, use the AES/SPDIF switch to specify AES or SPDIF.
6.
Set the digital audio source device to transmit digital audio and to synchronize to either the
external master clock or to the 2192.

You cannot clock to S/PDIF while listening to AES/EBU or vice versa.

Because the signal is briefly interrupted when new settings are applied, do not change any
front panel knob or switch settings while transcoding is in process.

The 2192 does not perform sample rate conversion.
