Problem: Mona doesn’t seem to recognize the synchronization clock to
which it is connected.
Solution: Although it may seem obvious, the first thing to check is that
there is a physical connection between the device generating the clock and
Mona’s rack mount interface. Just because multiple devices are connected
to the same computer doesn’t mean they are synchronized. Next, be sure
that you have selected the desired input clock source in the Mona Echo
Console.
Problem: Recordings made using the S/PDIF port contain occasional pops
or skips.
Solution: When recording with the S/PDIF port, you must manually select
the S/PDIF clock as the input clock. This can be done using the Mona Echo
Console.
Problem: On Windows startup you hear a high pitched squealing sound or
your S/PDIF or ADAT signal has gone crazy.
Solution: Reset the sample rate of Mona. Windows always sets the sample
rate to 11kHz at startup. Because neither S/PDIF nor ADAT support this
rate, you will have problems syncing until you reset Mona’s sample rate to
one within spec (like 44.1 or 48kHZ). You can do this by playing a wave
file of the appropriate sample rate through Mona’s outputs. Then you will
be able to sync properly.
Problem: I installed my older Echo card (Layla, Gina, Darla, Darla24) and
it messed up my Mona installation.
Solution: The old drivers (5-02 or earlier) for those cards will mess up a
Mona install. Just uninstall Mona, then install the older card and reinstall
Mona. You will be fine if you always install the older card first, then the
newer one. We have fixed this problem with driver versions 5-04 and later.
