DESCRIPTION

The ATI Model DDA-416/WC106 is an integrated package containing four 1X4 AES/EBU Digital

Audio Distribution Amplifiers and one 1X6 Clock Distribution Amplifier. Operation of the unit is

simple and straightforward, and it is housed in a rugged 2U rack mount enclosure. All audio

connections are made directly to the unit's built-in XLR and BNC connectors, and no special

breakout cables or accessory jack panels are required.

Signal routing is provided via rear panel accessible DIP switches to provide exceptional versatility.

The front panel provides full status monitoring of all input signals, including displays for Input

Sample Rate, Word Length, Digital Errors and Pro/Consumer mode. A unique Source Monitor &

Control function allows front panel setup for input termination and input equalization. Input Fault

displays are also provided, as is switchable Re-clocking on AES/EBU 1, 2, 3 and 4 inputs.

The DDA's Clock Distribution Amplifier has both Input and Loop-thru outputs to allow downstream

equipment to be fed from the input reference signal. When no downstream equipment is

connected, the inputs should be terminated via the front panel Input Termination switch. Loop-

through inputs are also provided for AES SYNC IN input.

INPUT FAULT LEDs indicate loss of carrier occurring on any input, regardless of the position of the

Source Monitor selector.

A front panel lock switch protects all settings. The DDA retains all of its settings, even if power is

removed.

INPUTS

Incoming AES/EBU formatted digital audio data and AES11 sync is applied to individual input

transformers. Input termination resistors at 75 ohms for BNC Word Clock inputs or 110 ohms for

XLR inputs can be switched in or out of the circuit with the front panel Input Term switch. Inputs

should always be terminated unless they are looped thru to another device or a second DDA input.

The last device or input should always terminate the line. Automatic Input Equalization is provided

for all inputs, as selected on the front panel.

A Frame Clock signal is derived from AES INPUT 1. This Frame Clock signal is available for

routing to all XLR and BNC outputs.
