AIR TEMPERATURE AND HUMIDITY

Normal operation of this unit is warranted while operating in a temperature range of +5 to +40°C, with

relative humidity ranging from 5 to 85%. Care should be taken to avoid operation outside these limits or

erratic operation may result.

FUNCTIONAL STANDARDS

All Model MCDA-208/WC106 units are in conformity with the following industry standards:

AES3-2003, AES11-2003 and IEC958 SPDIF

DESCRIPTION

The ATI Model MCDA-208/WC106 is an integrated package containing an ultra-low jitter studio master

clock generator, two 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.

When used as a studio master clock, the MCDA can generate an exceptionally stable 44.1, 48, 88.2,

96, 176.4 or 192 kHz clock reference for the purpose of synchronizing all of your connected digital

equipment. This single clock source assures a trouble-free digital workflow throughout your digital

facility. The output clock format can be either Word Clock or Super Word Clock, and this signal is

available on all six of the MCDA's individually driven BNC outputs. The Clock Generator output can

also be routed to either or both AES/EBU XLR output groups.

If you prefer to use another source for your reference clock, the MCDA can function as a 1X6 Clock

Distribution Amplifier. It can accept an AES3 audio signal or an AES Word Clock as an input, and will

output either Word Clock or Super Word Clock from its six BNC output connectors. These reference

clock signals can also be routed to either or both AES/EBU XLR output groups as word clock.

The Clock Generator section provides automatic switchover. Failure of an external clock will cause the

Clock Generator to automatically generate its own preprogrammed reference signal. Internal clock can

also be selected manually.

Since the purity of the clock reference is critical to the quality of the finished audio product, ATI has

taken steps to assure that the MCDA generates the lowest jitter clock reference available. The MCDA's

internal reference is derived from a 24 MHz precision oscillator and divided down to achieve an ultra-

stable signal, rather than multiplying up from a base reference as in some other units.

The MCDA'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.
