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.

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.

Stadium: recreates a large stadium using very long reverberation times.

Stage: recreates a stage environment, emphasizing sound from the front speakers.

Hall: recreates a hall using lots of reflections. Suitable for orchestral music such as classical and opera.

Disco: recreates the disco or club music effect. It is suitable for all types of music that are played in

disco.

Live: suitable for all types of music.
