Troubleshooting
The table below lists several ADLY-4/B problems, and provides a variety of “checklist” procedures
designed to solve them.
Problem Procedure
Power LED does not
light, no outputs.
• Ensure wall supply is plugged in properly and power connection is tight,
not loose.
• Check voltage from wall power supply for minimum 6 volts DC. Measure
voltage at the supply connector, when disconnected from the ADLY-4/B.
REF LED does not
light with an AES3id
input connected to
the
REF input
BNC’s.
• Check that the Reference Select Switch is in the down position.
• Ensure that the amplitude of the AES3id signal is between .4 and 1.2
volts p-p, when connected to the ADLY-4/B REF Input BNC’s.
• Ensure that sample rate of the reference input is not outside the 30-
50kHz range.
REF LED does not
light with an AES3id
input connected to
the
Channel 1 Input.
• Check that the Valid AES3id Input 1 LED is lit.
•
Check that the Reference Select Switch is in the up position.
Input Valid LED’s
won’t light.
• Ensure that the amplitude of the AES3id signal is between .4 and 1.2
volts p-p, when connected to the ADLY-4/B.
• Ensure that sample rate of the input is not outside the 30-50kHz range.
Clicking sound in
audio tones.
•
Check that the REF LED is on.
• Check that the devices that are feeding the ADLY-4/B inputs are also
locked to the same source as the ADLY-4/B reference.
NOTE Please contact the RJM factory if the problem still exists after completing the
above procedures.
