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
The THEATER mode creates a sound field that resembles the acoustic feeling

of a standard live performance theater, with stereo and even pure mono sources.
HALL 1
The two Hall modes create sound fields that resemble a small (HALL 1) or

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
may 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

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 Off (Stereo)
These modes turn off all surround processing and present the pure left- and right-channel

Surround Off (Bypass) presentation of two-channel stereo programs. The Surround Off (Bypass) mode may only be
DSP Surround Off
used with analog source inputs, as it preserves the analog format of the audio signal for its
entire path of travel through the receiver to the speaker and subwoofer outputs, bypassing
all digital processing. Digital bass management is not available in Surround Off mode. The
DSP Surround Off mode can be used with either an analog or digital input, as the signal
undergoes digital bass management to optimize the distribution of the low frequencies
between the main speakers and a subwoofer.
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 former 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.
