ADA: INTRODUCTION
The CEDAR ADA is a 24-bit, 96kHz 1U rackmount unit that produces an AES/EBU
or SPDIF digital audio output from a balanced or unbalanced analogue stereo
audio input. It also produces a stereo balanced or unbalanced analogue output
from an incoming AES/EBU or SPDIF digital input signal.
At any given time, the unit operates in one of four sync modes:
Master Mode
The clock signals are generated internally by an on-board master clock at a user-
selectable rate: 32kHz, 44.1kHz, 48kHz, 64kHz, 88.2kHz or 96kHz.
Slave Mode
If a digital signal is present at the selected digital input, the ADA synchronises to it.
If no such signal is present, no output is generated.
Auto Mode
If a digital signal is present at the selected digital input, the ADA synchronises to
it. If no such signal is present, the ADA uses its internal master clock at the user-
selected sample rate.
Auto Lock Mode
This operates in the same manner as Auto Mode except that, if no digital signal
is present, the ADA uses its internal master clock running at the most recently
synchronised sample rate.
When operating in any other than Master Mode, the front panel power LED will
ash whenever the ADA is not synchronised to an incoming digital signal.
