Turning the pulsar or allows the user to select one of the following synchronization
modes:
Auto by Prbl
(»Automatic by Preamble«) - The receiver synchronizes itself
onto the SDIF-2 preambles automatically - for each input
channel separately where necessary - and then begins scanning
the incoming audio bits. Any misalignment between left and
right of up to 5µs, arising out of, for example, cables of different
length, is automatically compensated. This mode is only suitable
for use with devices which correspond exactly to the SDIF-2
specifications. This covers a range of devices, including all
devices manufactured by SONY.
Man Prbl Mrg
(»Manually - Preamble Marginal«) - The SDIF-2 receiver
synchronizes itself onto the outgoing word clock of the SDIF-2
transmitter with a degree of delay which can be adjusted, i.e. the
time at which the incoming audio bits are scanned can be
adjusted manually. However, this delay time is valid for both
channels, so both cables must be of the same length. The lock
LED readout reacts to the reception of a correct SDIF preamble.
The audio path is only open when the signal has locked, so the
preamble itself must be correct.
Man Prbl Bad
(»Manually - Preamble Marginal«) - The SDIF-2 receiver
synchronizes itself onto the outgoing word clock of the SDIF-2
transmitter with a degree of delay which can be adjusted, i.e. the
time at which the incoming audio bits are scanned can be
adjusted manually. The preamble received is not considered.
The lock LED readout remains orange, as the locking status
cannot be established. The audio path remains open, so
interference is to be expected if the inputs are open. This mode
should be selected when working with devices which have no
preamble, or where the preamble has been destroyed. The
LEXICON 480, where the rear 1½ cell varies in width according
to the sample rate, is a typical example.
