Dolby Digital Surround

The Dolby Digital Surround system requires connections of all 5 speakers (front left, center, front right,
surround right, surround left) for the correct surround sound reproduction. This 5.1 channel digital surround
format enables five individual full-range (20Hz-20KHz) channels plus an LFE (Low Frequency Effects) channel
for the low-range (20Hz-120Hz) effects. It creates a realistic sound similar to the theaters and cinemas. A
large proportion of DVD discs use this system for sound.

Dolby Pro Logic II Surround

The Dolby Pro Logic II Surround system is the next generation in Dolby Surround decoding. It creates five full-
bandwidth output channels from two-channel sources. This is done using an advanced, high-purity matrix
surround decoder that extracts the spatial properties of the original recording without adding any new sounds
or tonal colorations.

Dolby Digital Surround EX

Dolby Digital Surround EX uses encoding techniques as Dolby Digital 5.1, however an additional rear center
channel is matrix encoded onto the left and right surround channels for an even more exciting, enveloping
surround-sound effect.

3 Stereo

3 Stereo produces three channels (front left, center, front right) of sound from a two channels analog signal. It
is not a surround format so it does not require surround speakers.

Soundfield Effects

The digital Soundfield Effects recreates the effects of sounds reflected from walls or ceilings to obtain the
sound presence of real environments.
