ohms in the "Qutput Configurations" menu.
11. Trouble-Shooting
No sound:
- check the speaker connections (cables may be loose) and the settings (100V / 4Ohm)
- check the speaker wiring (cables may have been kinked)
- check the supply voltage
- check whether there is an audio signal
- check the configuration / settings (if necessary, email us your configuration file)
Humming:
Make sure that the inputs on the amplifier are connected.
Otherwise there is a ground problem due to grounding / shielding the sound source / amplifier. Make
sure that your 230V cabling complies with the EMC guidelines.
Different ground potentials (source & amplifier) can result in humming noises.
Remedy: Common mass or a mass separation filter.
Noise (cracking):
Make sure that only shielded cables are used.
Check the cable routing for cable crossings or parallel laying to 230V cables and eliminate them
(induction problems). If possible, cinch cables should be laid at a distance of 30 cm.
Power amplifier switches channel off
Check the clip limiter settings of the channels.
