Digital to Analog Conversion
Digital signals can be converted to analog at sampling rates between 44.1 and 192kHz. All 24-
bits of the digital input signal are converted. If the digital source has less than 24-bit resolution, it’s
recommended that high quality dither be applied before conversion.
Any of the digital audio input sources (AES/EBU, S/PDIF, or ADAT S-MUX), or the digitized
analog inputs can be converted to analog audio.
When performing D/A conversion, the 2192 sample rate must match the sample rate of the digital
audio source signal.
Important: Do not change any front panel knob or switch settings while D/A conversion
is in process. The signal is briefly interrupted when new settings are applied.
D/A Using Internal Clock
This is the simplest use of the 2192. In this configuration, the 2192 is the master system clock.
Four word clock outputs are provided so the 2192 can be used as a master system clock source
without cascading the clock through external devices, which can degrade the clock signal.
To perform D/A conversion using the internal 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 Internal.
4. Set the 2192 Sample Rate knob to match the sample rate of the digital audio source signal.
5. Set the 2192 Analog Outputs knob to select the digital audio source (AES/SPDIF or ADAT). If
the source is set to AES/SPDIF, use the AES/SPDIF switch to specify AES/EBU or S/PDIF.
6. Set the digital audio source device to synchronize to the 2192 and transmit the digital audio
signal.
D/A conversion is continuous in internal clock mode.
