• 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 [oval 16] until
SUB (LFE)
appears.
• 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 [oval 16] 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
