DA12 has power, but is not outputting time code

Problem

The DA12 is powered on and its input is connected, but no time-code signal is detected at one or more outputs.

Possible causes

• Gain is too low: the output signal may be too weak for the receiving device to detect.
• The output is shorted: a damaged cable, connector or connected device may short the signal.
• Too much resistance on the line: cable problems or poor connections may weaken the signal reaching the receiver.
• A faulty output: an individual DA12 output may not be working.

Troubleshooting steps

1. Try another output in the same bank. Move the same cable and receiver to another output. If it works there, the original output may be faulty.
2. Check the output cable. Look for loose connections or damaged connectors, then try a known-working cable. If the replacement works, repair or replace the original cable.
3. Try the other output bank. Test A and B independently, connecting the source to the matching input for each bank. Then use the Select switch to couple the banks, with input A feeding both, and try an output in each bank again.
4. Increase gain gradually. Turn the affected bank's gain control clockwise in small increments while watching for the receiver to detect time code. A and B have separate gain controls; adjust the bank being tested.

If the problem persists

Contact Masterclock Support. Tell them which outputs and banks you tried, whether a different cable helped, and whether increasing gain changed the result.
