DOLBY DIGITAL
Available only with digital input sources encoded with Dolby Digital data. It provides up to five separate
main audio channels and a special dedicated Low Frequency Effects channel.
DTS
Available only with digital input sources encoded with DTS data. Available on special DVD, LD and
audio-only discs, DTS provides up to five separate main audio channels and a special dedicated low

PRO LOGIC
The standard mode for analog surround sound decoding. It uses information encoded in a two channel

this mode for accurate reproduction of programs bearing the Dolby Surround, DTS Stereo, UltraStereo
or other “Surround” logos. Surround-encoded programs include videocassette, DVD and LD movies, TV
and cable programs, radio programs and audio CDs. Dolby Pro Logic processing may also be used to
provide a pleasing surround effect with some stereophonic source material that does not carry surround
encoding.

This mode turns off all surround processing and presents the pure left and right channel presentation 
OFF (STEREO)
of two channel stereo programs.
