Status Select Switches
These switches determine the channel status of the digital signals.
The channel status bits of the digital audio signal can be Professional or Consumer,
as determined by switch 1. At sample rates higher than 48kHz, Consumer mode is
not available, so Professional mode is used and this switch is ignored.
If de-emphasis is selected (switch 2) the ADA will decode 50/15µs emphasis when
the incoming channel status indicates that this is appropriate.
The wordlength for the A/D conversion can be set to 24, 20 or 16 bits. When the
signal is truncated from 24 bits, a psychoacoustic lter is applied to maintain
optimum signal quality.
These settings are summarised by the following tables:
Switch Status Meaning
1 ON PROFESSIONAL
1 OFF CONSUMER
2 ON DE-EMPHASIS AUTO
2 OFF DE-EMPHASIS OFF
Switch Wordlength
16-bit 20-bit 24-bit
3 OFF OFF ON
4 OFF ON ON
All current CEDAR digital processors are 24-bit, so we advise you to leave the
wordlength at 24 bits.

(button in) for each of the digital input and output.

This button switches the analogue input between the balanced (button out) and the
