Mytek Protools-HDX DIO Card – User's Manual
Multiple converters
A Protools HD system can accept up to two converters
connected to each port. Mytek DIO-HDX card allow to use four
converters connected to one HD system port – for more
information please read master/slave mode section in this
manual. Various brands can be mixed as long as they are all
capable of emulating the Avid I/O interface. If multiple
converters are used, one serves as a source of the clock signal
(Master), with the rest of the devices receiving it (Slave).
Our recommended setup is to use the Mytek 8X192ADDA as
the clock source feeding all other converters from multiple
wordclock outputs to all slave devices in a star configuration.
8X192 ADDA converter has 6 clock outputs. Clock signal
originates from the very precise CX797 module. Because of
that 8X192 ADDA converter is the best clock signal source
in the majority of multiple devices configurations

ADDAs
In system with multiple
units, double check that the
configuration of clock signal
lines, synchronization
sources and sampling
frequency’s of all converters
in the system are correct.
Correct clock configuration
is necessary for proper
operation of converters and
for best sound quality.

the clock master for the
whole studio. There is no
benefit of using a dedicated
house clock generator.
Clocking off Mytek internal
clock generator produces
superior results because the
clock and clock line high
current drivers are the best
in the industry.
Changing external
synchronization source
while the program is
running may result in
improper operation of
converters and loud cracks
in the analog section.
