A Note About Dolby Digital
(AC-3), Large Front Speakers
And Powered Subwoofers
While it is logical to connect the
Powered Subwoofer to the
"Subwoofer Output" or LFE (Low
Frequency Effects) output of a
Dolby Digital (AC-3) equipped
system, there are some instances
when bypassing this output can
result in better sound.
Most Dolby Digital (AC-3) decod-
ers automatically remove the low
bass content from all the Main
speakers if the "Subwoofer Output"
switch is set to "On". The Main
speaker "Large/Small" switches still
appear to function, but they are
actually locked in the "Small"
mode.
This automatic bass limiting is
unnecessary with large Main
speakers. You can effectively send
all low-bass and Low Frequency
Effects signals to both your Main
