SPECIFICATIONS

*This specification conforms to Federal regula-

actual sound output. For this reason we also
specify the calculated maximun sound output.

TROUBLE SHOOTING

Possible Solution

• Check AC plug and green LED on

the back; make sure outlet is opera-
tional

• Check volume control on subwoofer

• For speaker level wire conections,

check (+) on amplifier to (+) on

(-) to (-)

• Check that RCA line level inputs of

the subwoofer are not wired from
speaker level outputs of amplifier

• Turn crossover frequency down

• Move phase switch to “REV”

and compare

• Turn volume up on subwoofer

• Move subwoofer into corner

• Move phase switch to “REV”

and compare

• Secure all wire and line level

connections

• Route all speaker and/or line level
