ATI Audio will head to Vegas and the NAB Show with several digital distribution products.
First out of the gate is the DDA-416/WC106, a package containing four 1 x 4 AES/EBU digital audio distribution amplifiers and one 1 x 6 word clock distribution amplifier. The unit is housed in a 2 RU enclosure. Audio connections are made to the unit’s XLR and BNC connectors, no special breakout cables are required.
Signal routing is via rear-panel DIP switches for versatility. The front provides status monitoring of input signals, including displays for input sample rate, word length, digital errors and pro/consumer mode. A source monitor and control function allows for front-panel setup for input termination and input equalization. The DDA’s clock distribution amplifier has 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 may be terminated via the front-panel input termination switch. Loop-thru inputs are provided for AES sync sources. Summary alarm LEDs indicate faults occurring on any input, regardless of position of the source monitor selector. A front lock switch protects settings. The unit has a nonvolatile memory; if power is removed settings are safe.
The MCDA-208/WC106 is similar yet different. It is designed to give studios centralized control over digital audio signals. The 2U box contains an “ultra-low jitter”192 kHz studio master sync generator, two independent 1 x 4 AES/EBU digital audio distribution amplifiers and a 1 x 6 clock distribution amplifier. When used as a studio master clock, the MCDA can generate a highly stable 44.1, 48, 88.2, 96, 176.4 or 192 kHz clock reference for synchronizing digital equipment. Automatic fallback allows external sync signals to be used, with the internal generator providing backup if external timing is lost. While serving as a master clock generator, two independent 1 x 4 AES/EBU distribution amplifiers handle separate stereo programs. Configurable signal mapping lets you route audio, clock or sync signals to any output group.
