Up to 30 ft.

The wires for both speakers  
should be the same length. If  
one speaker is placed closer to  
the amplifier than the other,  
hide the excess wire behind  
the wall.  
Speakers and electronics ter-  
minals have corresponding (+)  
and (–) terminals. It is impor-  
tant to connect both speakers  
identically: (+) on the speaker  
to (+) on the amplifier and (–)  
on the speaker to (–) on the  
amplifier. Wiring “out of phase”  
results in thin sound, weak bass  
and a poor stereo image.

Front or Rear Speaker Outputs  
AS SUB  
The AS SUB has two pairs of  
speaker connections. Connect  
one set of terminals (input)  
to the left channel of your  
amplifier. Connect the other set  
of terminals (input) to the right  
channel of your amplifier. Then  
connect the left satellite to the  
left output and the right satel-  
lite to the right output.

Painting the Speaker Frame and Grille  
AS Series loudspeakers can be  
painted to match any style of  
decor. If you wish to change  
their color, the satin finish on  
the grille and frame will func-  
tion as a primer coat. Before  
painting, install the paint guard  
(in the assembly kit) securely  
into the recess in the baffle.  
This will protect the speaker  
components and baffle from  
paint residue.  
Use a high-quality spray paint,  
and apply a thin coat of color.  
Be certain the grille perfora-  
tions remain free of paint.  
Filling them with paint will  
diminish the sound quality.  
Note: Gently remove the  
acoustical foam blanket from  
the grille before painting.  
Reattach the blanket after the  
paint has dried.

Troubleshooting  
If there is no sound from  
either of the speakers, check  
the following:  
If there is no sound coming  
from one speaker, check the  
following:  
If the system plays at low vol-  
umes but shuts off as volume is  
increased, check the following:  
• Receiver/amplifier is on and a  
source is playing.  
• Check the “Balance” control on  
your receiver/amplifier.  
• Check all wires and connec-  
tions between receiver/amplifier  
and speakers. Make sure all wires  
are connected. Make sure none  
of the speaker wires are frayed,  
cut, or punctured.  
• If more than one pair of main  
speakers is being used, check the  
minimum impedance require-  
ments of your receiver/amplifier.  
• Check all wires and connec-  
tions between receiver/amplifier  
and speakers. Make sure all wires  
are connected. Make sure none  
of the speaker wires are frayed,  
cut, or punctured.  
• Check all wires and connec-  
tions between receiver/amplifier  
and speakers. Make sure all wires  
are connected. Make sure none  
of the speaker wires are frayed,  
cut, or punctured.  
• Review proper operation of  
your receiver/amplifier.  
If there is low bass output,  
check the following:  
• Make sure the connections to  
the left and right “Speaker  
Inputs” have the correct polarity  
(+ and –).
