in a two channel stereo recording to produce four distinct outputs: Left, Center, Right and

a Mono Surround channel. Use 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.

Logic 7 is an advanced mode that extracts the maximum surround information from either
Delay time not adjustable
LOGIC 7 M
surround-encoded programs or conventional stereo material.The Logic 7 C or Cinema mode
should be used with any source that contains Dolby Surround or similar matrix encoding.
Logic 7 C delivers increased center channel intelligibility, and more accurate placement of sounds
with fades and pans that are much smoother and more realistic than with other decoding
techniques. The Logic 7 M or Music mode should be used with analog or PCM stereo sources.
Logic 7 M enhances the listening experience by presenting a wider front sound stage and greater
rear ambience. Both Logic 7 modes also direct low frequency information to the subwoofer
(if installed and configured) to deliver maximum bass impact.
DOLBY 3 STEREO
Uses the information contained in a surround encoded or two channel stereo program to

create center channel information. In addition, the information that is normally sent to the
rear channel surround speakers is carefully mixed in with the front left and front right
channels for increased realism. Use this mode when you have a center channel speaker
but no surround speakers.
