10.3.3. RESET 

 
Press the ADJUST / SET button (8) for 

about 5 seconds

 
Note: 

A RESET (reset to factory settings) 

deletes all settings

 and 

all saved presets

 and 

sets all outputs to 4-8 

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.
