DL452 digital I/O module

DL452 digital I/O module
The DL452 digital I/O module provides four (stereo) AES/EBU inputs and outputs. Its
rear panel houses these I/Os in four pairs. Each input has a check and a sync LED and
each output has a check and a mute LED.
Each AES/EBU input can run at sample rates up to 96kHz (44.1Hz, 48kHz, 88.2kHz and
96kHz) using a sample rate converter (SRC). If the digital input is synchronous with
the system clocks, the SRC can be bypassed to remove approximately 1ms of delay,
which is inherent in the sample rate conversion process.
Each AES/EBU output can also run at sample rates up to 96kHz by using an (SRC).
There are two potential clock sources for the digital outputs: the system and the
coinciding digital input. When using the system to drive the digital outputs, the output
SRC is bypassed and the sample rate of the output is matched to the system. When the
digital input clocks are used to drive the digital outputs, the SRC is enabled and the
audio output is converted from the sample rate of the system to the sample rate of the
digital input.

Green check LED illuminates to show
when a channel is selected on the console.
These are controlled by the console and are
used as a visual aid to locate specific
connectors.
