TROUBLESHOOTING & FAQ
Troubleshooting
• My microphones are not producing
signal?
If required, double check that phantom
power is turned on via the front panel switch,
try swapping XLR cables, then double check
all connections to the recorder/interface.
• Cannot clock the ASP800 from an
external clock source, or you are
experiencing clicks & pops?
Double check that you have set the
clock source to external by using the front
panel SAMPLE RATE switch, press it until
it is flashing green. This selects external
clock mode and the unit is ready to accept
an incoming clock source via the BNC input.
From here, double check your master clock
source, and ensure it is connected via a
75ΩBNCcoaxialcabletotheASP800BNC
wordclock input.
Providing that you have a valid clock source,
ASP800 should sync to it without issue and
the SAMPLE RATE led in the switch will turn
to solid illumination. This shows that the unit
is locked. If you experience pops & clicks -
double check any master/slave device
configurations and cabling. A system should
only have one master clock.
