ASP880 Block Diagram Troubleshooting & FAQ
Troubleshooting
• My microphones are not producing 
signal?
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.
• I cannot clock the ASP880 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.
From here, double check your master clock 
source, and ensure it is connected via a 
75ΩBNCcoaxialcabletotheASP880BNC
wordclock input. 
Providing that you have a valid clock source, 
ASP880 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.
