Faults
Although your NLC5.1ST will provide you with years of trouble free service, occasionally problems may
occur. Below is a listing of the most common fault conditions and some pointers about where to start
your trouble-shooting before calling for support.
No Sync: AES sync has been lost. Please check the source equipment and all cable connections.
Ensure that NLC5.1ST is operating in the proper input mode for your application and is configured for
the correct input port.
CRC Error: NLC5.1ST has encountered a CRC mismatch error in the audio stream. This may be due
to a corrupted or invalid channel status bit sent by the source equipment.
Validity Error: A problem has been encountered with the validity bit and audio output has been muted.
Check that there are no errors on the source equipment preventing it from passing valid audio data.
Bi-phase Error: A bi-phase error in the audio stream could be caused by bad audio data coding or an
un-recoverable clock rate in the biphase mark code. Check the source equipment is properly configured
to output data in the correct format.
No Parity Error: A parity error is most likely caused by loose cables or a hardware AES interface
malfunction. Check the source equipment and NLC5.1ST with known good equipment to determine if
there is an equipment malfunction.
Clock Error: A valid clock signal was not found or could not be recovered from the biphase mark code
on the configured interface. Check your cable connections as well as the clock source input
configuration under the I/O menu.
