If the front left/right speakers are set to LARGE, three options are
available:
I If no subwoofer is connected to the AVR21EN, press the
‹
/
›
Navigation Button F until NONE appears. With this option,
all bass information will be routed to the front left/right
“main” speakers.
I If a subwoofer is connected to the AVR21EN, you have the
option to have the front left/right main speakers reproduce bass
frequencies at all times, and have the subwoofer operate only
when the AVR21EN is being used with a digital source that
contains a dedicated low-frequency effects, or LFE, soundtrack.
This allows you to use both your main and subwoofer speakers
to take advantage of the special bass sounds created for some
movies. Press
‹
/
›
Navigation Button F until SUB (LFE)
appears.
I If a subwoofer is connected and you wish to use it for bass
reproduction in conjunction with the main front left/right
speakers, regardless of the type of program source or surround
mode you are listening to, press the
‹
/
›
Navigation Button F
until SUB L/R+LFE appears. When this option is selected,
a full-range signal will be sent to the front left/right “main”
speakers, and the subwoofer will receive LFE information and
the bass frequencies under the selected crossover point.
When all initial speaker “size” settings have been made, you now
have the option to take advantage of the AVR21EN’s Quadruple
Crossover system, which allows individual crossover settings to be
made for each speaker group. The low-frequency crossover point
is the frequency below which the signal will be redirected to the
subwoofer and is set by the design of your speakers. Depending
on the design and driver complement of your speakers, it is
usually the lowest possible frequency the speaker is capable of
reproducing.
Before making any changes to the settings for the crossover point,
we suggest that you find the crossover point for the speakers in
each of the four groupings, front left/right, center front, surround
and surround back, by looking at the specifications page of each
speaker’s owner’s manual, by getting that information from the
manufacturer’s Web site, or by contacting your manufacturer’s
customer service department. You will need this figure to
accurately configure the next group of settings.
NOTE: When any speaker group other than the front left/right
speakers is set to LARGE, the crossover may not be adjusted,
as the feed will be full-range, with no sound being derived for
the subwoofer from that position.
The factory default setting for all speaker positions is 100Hz.
If that setting is acceptable for all channels, then no adjustments
are needed and you may skip this section. However, should you
wish to change one of the settings, please proceed by pressing the

The available choices for low-frequency information to be sent to
the subwoofer, rather than to the main speaker channel, are 40Hz,
60Hz, 80Hz, 90Hz, 100Hz, 120Hz and 200Hz. Pick the choice that is
identical to the information for the speakers, or if an exact match
is not possible, pick the closest choice that is ABOVE the speaker’s
low-frequency limit, to avoid the creation of a low-frequency
“hole” where your system will have no bass information.
The setting for the crossover point for the SUBWOOFER channel,
which is created to provide specific low-frequency information in
many movies with digital soundtracks, may be set to match the
crossover for any of the four speaker groups. Since the crossover
point commonly used in the creation of the SUBWOOFER channel
is 120Hz, we recommend that you select the speaker group
whose crossover point is closest to 120Hz. To do this, press the

crossover settings for all inputs, or to have different settings for
each input. In most cases, the factory default setting of GLOBAL
will be appropriate, as most systems do not need individual speaker
