Midas DL452 AES/EBU Input/Output D-Card for DL451, DL351, PRO3, PRO6 and PRO9 Surfaces

The Midas DL452 AES/EBU Input/Output Card 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.
