3. External
Synchronisation and
the Sample Rate
Converter (SRC)
The MSD has been designed to run on a fixed
internal sample rate at 48 kHz. However the user
can force the MSD to synchronise to any of the
available AES-3 Inputs.
• Please refer to section 18 for a complete set of
Synchronisation flowcharts for all supported
models
Since the unit’s internal sample rate also deter-
mines the AES output sample rate you can use the
external sync feature to synchronise the AES out-
puts sample rate. For details on how to set up the
MSD for external synchronisation please see sec-
tion 8.2.4.1 “SRC Bypass and external sync” in the
software manual. It is normal that professional
audio equipment such as mixing consoles are fitted
with sample rate converters in their AES input
stage. In these cases it is not necessary to syn-
chronise the AES output signal.
When an external sync source has been selected,
the MSD will sync to this input whether a valid sync
signal is present or not. If no valid signal is detec-
ted an error warning will be displayed on the MSD.
Even though the MSD is able to lock up to AES-3
signals at 96 kHz, an external AES-3 sync signal
with a sampling rate higher than 48 kHz should not
be used, as it may cause glitches in the audio
stream.
Synchronising to a lower sample rate than 48 kHz
(like 44.1 kHz) will not be a problem. It is however
