SYMPTOM

 

No Sound in One Channel 

 

 

 

CHECK POINT   

 

 

 

Check Speaker Leads. 

 

 

 

 

 

 

 

 

CURE 

 

 

 

 

 

Inspect for short circuit  

 

 

 

 

 

Check for open Connection or blown speaker. 

 

 

 

 

CURE

 

 

 

 

 

 

Check Speaker Leads, reverse Left and Right RCA inputs to   

 

 

 

 

 

determine if problem is occurring before the amp. 

 

SYMPTOM

 

Amp Turning Off At High Volume 

 

 

 

CHECK POINT   

 

 

 

Check Speaker load impedance 

 

 

 

 

 

 

 

 

CURE 

 

 

 

 

 

Inspect that speaker load impedance recommendations are followed. 

 

 

 

 

 

Check wiring configuration for speakers is correct. 

(To Verify proper load impedance, use an OHM meter to 
measure the total load for each channel of  the amplifier.)

 

 

 

 

 

SYMPTOM

 

System Protection LED is Lit 

 

 

 

CHECK POINT   

 

 

 

Temperature Shut-down 

 

 

 

 

 

 

 

 

CURE 

 

 

 

 

 

Check for proper air ventilation 

 

 

 

 

 

Change amplifier location 

 

 

 

CHECK POINT   

 

 

 

Speaker output shorted 

 

 

 

 

 

 

 

 

CURE 

 

 

 

 

 

Check speaker wiring 

 

 

 

 

 

Check for blown speaker by disconnecting one at a time  
and check for LED change.
