Clock and synchronisation system
The clock system of AX32 supports various internal and external clock modes. AX32 has a precise and very
high quality internal sample clock generator, which also can be clocked also from an external clock signal by
means of a very accurate Digital Phase Locked Loop (DPLL) system.
The AX32 clock system has to
be set to the correct sample
rate with which the units
should operate. This is the case
both when operating with the
internal sample clock generator
as master clock or when
synchronised to an external
clock source. The Sample rates
supported is either based on
44.1 or 48 kHz sampling. An
external clock must always
have a correct base rate in
relation to the sample rate
used.
Figure 2, AX32 Sample clock circuit
The sample rate with which the AX32 should operate can be set manually via DADman or the front display,
or the sample rate can be adapted to an external digital device e.g. a Pro Tools DAW system. When using
the IP Audio interface powered by Dante™ the sample rate of the Dante™ I/O node to the IP Audio network
can be set to follow the sample rate of the AX32. When more AX32 units are operating in the same set up
or IP Audio network they must be set to the same sample rate.
For information on how to configure the synchronisation and sample rates, please refer to the
Operation section of this manual.
Router functions and principle
The AX32 Converter System includes a
very flexible router matrix. All input
signals can be patched to one or more
output interfaces on a mono channel
basis.
In order to set up the correct signal flow
in the AX32, the correct connections
have to be set in the matrix. This is done
via the DADman user interface. Any one
of the analogue or digital inputs
installed in the AX32 can be patched to
any analogue or digital output or split
into multiple outputs.
This means that the e.g. 16 analogue
input channels can be patched to the
Pro Tools output and the Pro Tools input
can be patched to a MADI output. And
at te same time two channels can be
patched to the analogue output.
Furthermore, e.g. 8 AES3 channels can
at the same time be patched to the
optical MADI output.
