Why is my second QSC ADS10T speaker connected in parallel not producing sound anymore?

Question

Accepted Answer

If your second QSC ADS10T speaker connected in parallel is no longer producing sound, several causes may be behind the issue. Here’s how to identify and resolve this concern:

1. Check the connections

Ensure that the cables connecting the speakers are properly connected and in good condition.
Check the connections on the speaker and on the audio source (amplifier, mixing console, etc.).

2. Test the cables

Try swapping the cable of the second speaker with that of the first to check if the cable is defective.

3. Power supply

Make sure the speaker is powered on and that the power indicator is lit.

4. Volume and gain settings

Check that the volume and gain of the second speaker are properly set and not at minimum.

5. Parallel configuration

Ensure that the speakers are correctly connected in parallel according to the manufacturer's recommendations.
Check that the total impedance does not exceed the limits supported by your amplifier.

6. Test with another source

If possible, connect the second speaker to another audio source to check if the problem comes from the source or the speaker itself.

By following these steps, you can generally identify the cause of the problem and address it. If the malfunction persists, it may be a hardware defect requiring technical intervention.
