Subwoofer Mode
The subwoofer output can be set
to Normal, or to an Enhanced Bass
mode.
The Enhanced Bass mode pro-
vides an output to your subwoofer
even when you are listening to a
stereo source with main speakers set
to Large. In the Normal mode, there
would be no subwoofer output in this
case, and the bass would only come
from the main speakers.
The Enhanced Bass mode has no
effect if the main speakers are set to
Small, as the subwoofer is automati-
cally engaged. It also has no effect in
5.1 or greater surround modes.

Crossover adjustment
The Receiver's bass management
allows you to redirect the low frequen-
cies of your speakers to a subwoofer.
The crossover point of your main left
and right speakers can be selected
from 40 Hz to 160 Hz, as can the
crossover point of your center and
surround speakers.
A setting of 80 Hz is a good start-
ing point if you are not sure of the
response of your speakers. In this
example:
• The subwoofer receives frequen-
cies below 80 Hz, from all speak-
ers whose size is set to Small.
• All speakers set to Small, receive
frequencies above 80 Hz.
Most manufacturers provide a -3 dB
speciÞ cation for their speakers. This
is the frequency where the speaker's
output has dropped by 3 dB. Set the
Receiver's crossover to this frequency
or above. If you cannot Þ nd this, set
the crossover to 80 Hz (the default).
Set your subwoofer's own cross-
over control to maximum frequency
or bypassed mode. If it is lower than
the Ultimate Receiver, there would
be a hole in the mid-bass, and bass
information would be missing.
