Bass Management

Low frequency sounds are usually better handled by the subwoofer speaker. Bass
Management handles the low frequency component of input signals, along with the
Low Frequency Effects (LFE) information encoded in the source format and passes
that information to a subwoofer (if available) and to speakers set to Large.

Speaker size settings

This feature sets whether Bass Management is on or off for a particular speaker,
which defines the frequency range that is output from that speaker. These settings
also enable or disable the subwoofer and set the crossover frequency.

Small

Bass Management is on for that speaker. The output to each speaker (other than the
subwoofer) is limited to frequencies above the Crossover Frequency. By default,
center and side speakers are set to small.

Large

Bass Management is off for that speaker. This mode allows the full range of audio
frequencies from the audio source to be fed through the individual channel's
output. This is sometimes set in the absence of a subwoofer as part of the system.
By default, front speakers are set to large.
All speakers set to Large, except the Center channel, will receive the summed audio
from the filtered low frequency signals from speakers set to Small.

None

This mode prevents any signal being sent to that channel's output. It is not an
option for front speakers.

(Surround back speakers only)
This mode determines whether the audio output channels for the back speaker(s)
will be passed to the Left Back and Right Back (in 7.1 setups) or to the Center Back
(in 6.1 setups).
If either of the one speaker options are chosen, the highest possible number of
outputs is 6.1 speakers. In this case, the output is directed to the left back channel.
If either of the two speaker options are chosen, the SSP 7.1 is able to output up to
7.1 channels. Source formats with discrete or matrix mixed 6.1 encoded channels
will output the surround back channel signal equally to the left and right back
channels. Dolby Pro Logic IIx listening mode option will output a stereo signal to
the left and right back channels.

By default, the back speaker is set to none, which prevents a signal being output on
the back channel(s).
