POWER
Indicates that low voltage DC is applied to the input of the voltage regulators.
EXTERNAL CLOCK FORMAT SELECT
When using an external clock source as a reference, the MCDA-112 accommodates a variety of input
formats, as listed:
Word Clock—Input through the 75 ohm BNC Input connector on the rear of the unit.
Super-Word Clock—Input through the BNC connector on the rear of the unit.
AES3—A standard AES/EBU signal. Input through the XLR connector at the rear of the unit, the
AES3 audio signal is removed and the source timing pulse is used for the reference.
AES11— AES11 is an AES signal containing only sync information.
When using an external input, use the EXTERNAL CLOCK FORMAT button to select the format input
to the unit.
The XLR input is 110 ohms, transformer balanced, and accepts a minimum level of 0.2 volt peak-to-
peak. The BNC input is 75 ohms, unbalanced, and accepts a minimum of 0.1 volt peak-to-peak.
Both XLR and BNC inputs contain loop-through outputs for the purpose of looping the input signal to
additional equipment. If the MCDA-112 is the last (or only) device to be fed by your external clock
source, be sure to terminate the input using the front panel INPUT TERM button.
SAMPLE RATE
When Clock Source switch is set to Internal, selects internal generator sample rate. (Note that the
MCDA does not generate 32 kHz sample rate.) When the Clock Source switch is set to External,
indicates sample rate of the external input from 32 kHz through 192 kHz. Input sample rate is not
indicated when working from Super Word clock.
OUPUT CLOCK FORMAT
Indicates either Word Clock or Super Word Clock format present at all 12 outputs. Press the SELECT
button to toggle the setting. Output clock format can be switched between Word Clock and Super-Word
Clock. Word Clock is the precise AES signal, as indicated on the Sample Rate display. Super-Word
Clock is a multiple of this frequency, used for compatibility with some other devices.
INPUT TERM
Indicates whether the input termination is Off or On. Press the INPUT TERM button to toggle the
setting.
