ATI Audio Inc MCDA-208/WC106 - Studio Master Clock

The MCDA-208/WC106 from ATI is an integrated solution containing an ultra-low jitter studio master clock generator, two 1 x 4 AES/EBU digital audio distribution amplifiers, and one 1 x 6 clock distribution amplifier. All audio connections are made directly to the unit's built-in XLR and BNC connectors, and no special breakout cables are required. Housed in a rugged 2U rack-mount enclosure, the unit is simple and straightforward to operate.

When used as a studio master clock, the unit generates a single stable clock reference that assures a trouble-free digital workflow throughout any digital facility. The output clock format can be either Wordclock or Super Wordclock, and is available on all six of the individually isolated BNC outputs. The clock generator output can also be routed to either or both AES/EBU XLR output groups.

The MCDA can also function as a 1 x 6 clock distribution amplifier when an external source clock is preferred. It can accept an AES3 audio signal or AES Wordclock as an input, and will output either Wordclock or Super Wordclock from its six BNC output connectors. These reference clock signals can also be routed to either or both AES/EBU XLR output groups. The unit can also derive a Frame Clock from the AES/EBU signal input at AES Input 1, available for routing to all XLR and BNC outputs.

The clock distribution amplifier has both input and loop-thru outputs to allow downstream equipment to be fed from the input reference signal. The clock generator section provides automatic switchover in the event of the external clock failure. Alarm LEDs indicate faults occurring on any input, regardless of the position of the source monitor selector, and a front panel lock switch protects all settings. The unit retains all of its settings even if power is removed.
