Troubleshooting
8 Noise increasing with accelerating vehicle
- This is a ground loop phenomenon. To verify if this noise is caused by an incorrect grounding, switch off
the amplifier and the audio source, then remove the amplifier's RCA cables (ensure that they are shielded
and are not touching the chassis once disconnected). Switch the amplifier and the audio source on.
- If the problem persists, it is a grounding problem. If it disappears, the problem is due to the RCA cables
being either damaged or too close to the power cables. It is thus necessary to change and place the RCA
cables opposite the power cables.
- In the event of a grounding problem, ensure that the ground cables are correctly connected and that the
quality of the contacts is good (no paint or varnish on the grounding area).
Once all these verifications have been undertaken and if the amplifier still does not work, contact
your nearest Focal distributor.
