Troubleshooting

Problem

Solution

 

 

• No Sound Only from Subwoofer

• Check the subwoofer's volume setting and

 

all connections. If your receiver has a

 

subwoofer on/off or variable subwoofer

 

output level control, ensure that the

 

subwoofer option it is turned on and that

 

the output level is at maximum.

 

• Make sure that the subwoofer's RCA

 

cable is connected to the receiver's

 

subwoofer output and not the subwoofer

 

input jack.

 

 

• Too Little Bass

• Check: subwoofer volume / frequency /

 

phase control positions; receiver tone

 

controls; program material; ensure that

 

the center channel mode on the receiver

 

is in the NORMAL or SMALL position. If

 

your receiver has a variable subwoofer

 

output level control, ensure that the

 

output level is at maximum.

 

• Try moving the subwoofer further into a

 

corner or towards the wall.

 

 

• Too Much Bass

• Check: subwoofer volume / frequency /

 

phase control positions; receiver bass /

 

loudness controls; program material;

 

move subwoofer further out of corner or

 

away from wall.

 

 

• Hum

• Check for faulty phono connecting cable.

 

• Try to separate phono cables from power

 

cords (they can induce hum into the

 

system). If that doesn't work, we

 

recommend you turn off your subwoofer

 

when it is not in use. This is most easily

 

accomplished connecting its power cord

 

to a switched power outlet on the back of

 

your receiver.
