a special dedicated low frequency channel.

DOLBY PRO LOGIC

The standard mode for analog surround sound decoding. It uses information encoded

15 ms – 30 ms

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.

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.

THEATER

This surround processing uses matrix surround decoding to simulate a standard movie or

stage theater with stereo and even pure mono sources.

HALL

The Hall mode offers matrix surround decoding that simulate

a medium-sized chamber hall or opera house with stereo and even pure mono sources.

VMAx Near

When only the two front channel loudspeakers are used, Harman’s patented VMAx mode

VMAx Far

delivers a three-dimensional sound space with the illusion of “phantom speakers” at the
center and surround positions. The VMAx N, or “Near Field” mode should be selected when
your listening position is less than 1,5m from the speakers. The VMAx F, or “Far Field” mode
should be selected when your listening positioin is greater than 1,5m from the speakers.

5-Channel Stereo

This mode takes advantage of multiple speakers to place a stereo signal at both the front and

back of a room. Ideal for playing music in situations such as a party, it places the same signal

at the front-left and surround-left, and at the front-right and surround-right speakers. The center
channel is fed a summed mono mix of the in-phase material of the left and right channels.

SURROUND

This mode turns off all surround processing and presents the pure left and right

LOGIC 7 C
LOGIC 7 M

An advanced mode that extracts the maximum surround information from either
conventional stereo material or surround-encoded programs. When used with encoded
material, decoding is more accurate in terms of the placement of sounds, and fades and pans
are much smoother and more realistic than with other decoding techniques. Logic 7 also
delivers increased spaciousness and a wider sound stage when it is used with conventional
natural stereo recordings and music programs throug the use of the natural surround
information present also in those stereo recordings. The Logic 7C or Cinema mode is tailored
to provide an optimal sound field for movie soundtracks. The Logic 7M or Music mode uses a
decoding formula that is best suited to music.
