• Verificare i diffusori e le connessioni

 

• Livello del volume surround troppo basso

• Aumentare il livello del volume surround

 

 

 

 

ASSENZA DI SUONO SUL CENTRALE CANALE

Diffusore non correttamente collegato

• Verificare il diffusore e la connessione

 

• Livello del volume centrale troppo basso

• Aumentare il livello del volume centrale

 

 

 

 

BASSI DEBOLI/ DIFFUSIONE IMMAGINE STEREO

Diffusori collegati fuori fase

• Verificare le connessioni di tutti i diffusori

 

 

 

dell’impianto

 

 

 

 

PASSA TEMPORANEAMENTE IN STANDBY, POI RITORNA AUTOMATICAMENTE ALLO STATO PRECEDENTE

L'amplificatore funziona a una temperatura troppo elevata.

Lasciare raffreddare l'amplificatore.

Eliminare la condizione di carico eccessivo.

I diffusori devono essere superiori a 4 Ohm nominali.
