Connect speaker wire from the receiver’s left and right
speaker outputs (the main or front connectors) as
shown in the diagram. Connect speaker wire from the
BassCube’s OUT TO SPEAKERS connectors to your
left and right speakers. Set the LOW PASS FRE-
QUENCY control according to the guide on page 13.
Note: When you activate the Subwoofer Out jack on a
Dolby Digital audio system, bass signals to the main
speakers are automatically filtered out. This is a fea-
ture of a Dolby Digital decoder’s bass management
system. How much bass is filtered out of the main
speakers depends on the Dolby Digital settings. If too
much bass is filtered out, your audio system will have
weak output in the frequency range where your sub-
woofer and main speakers overlap. This frequency
range is often referred to as “midbass.”
If you suspect your system has weak midbass
output, first make sure your subwoofer’s LOW PASS
FREQUENCY control is set at its full clockwise rota-
tion. Then check your audio system to see if its Dolby
Digital decoder has a “crossover” or “high-pass” fre-
quency adjustment for the main speakers. If it does,
set it at its lowest frequency setting. These two adjust-
ments should provide you with consistent bass output.
Unfortunately, there may not be an adjustment on your
audio system’s Dolby Digital decoder for main speaker
bass (other than small or large), or it may be hard to
hear any improvement. In this case, you can insure
accurate midbass output by inactivating the
Subwoofer Out jack of your Dolby Digital audio sys-
tem. (This doesn’t “remove” any of the bass signals
present in a Dolby Digital recording. The Dolby Digital
decoder just sends the Low Frequency Effects chan-
nel and all bass signals through the speakers desig-
nated as Large.) Set your Dolby Digital decoder’s
Front speaker size setting to Large and the Center and
Rear speaker size settings to Small. Then connect the
BassCube and front speakers as described above in
Speaker Level Connections. Afterwards, you can use
the BassCube’s LOW PASS FREQUENCY and
SUBWOOFER LEVEL controls to achieve proper
midbass output.
