give a full range output. Selecting SMALL for the multi-
channel speaker option will activate a high pass filter whose
crossover is dependent upon the sub-woofer low pass filter
frequency. For example, if the subwoofer low pass filter is set
to 80Hz, then the high pass SMALL speaker crossover will be
set to 90Hz.

Surround Sound
Dolby Digital
Dolby Digital is the reigning standard for surround sound
technology in general and 5.1-channel surround sound in
particular.
Dolby Digital is a highly sophisticated and versatile audio
encoding/decoding technology. Dolby Digital technology can
transmit mono, stereo (two-channel), or up to 5.1-channel
surround sound.
Pro-Logic II
Pro-Logic II is a dramatically improved matrix surround
system based on the original Dolby Pro Logic system. Pro-
Logic II offers two full-range stereo surround channels, more
sophisticated steering logic, high channel separation and an
exceptionally stable sound field. Dolby Pro-Logic II uses
simple servo circuits used to derive the five audio channels.
Unlike other "Surround Effects" found in other consumer
equipment, Dolby Pro-Logic II does not introduce unwanted
delays, echoes, reverberations or tonal colorations.
