MODE FEATURES
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 (HALL1) or
HALL 2 medium sized (HALL 2) concert hall, 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 1,5 m from the speakers. The VMAx F, or "Far Field" mode
may be selected when your listening position is greater than 1,5 m from the speakers.
The VMAx modes are also available using the Headphones Output
are being used, the Far Field mode will push the sound field away from your ears,
reducing the "inside the head" sensation often experienced when using headphones.
5-Channel Stereo This mode takes advantage of multiple speakers to place a stereo signal at both the front and
7-Channel Stereo back of a room. Depending on whether the AVR has been configured for either 5.1 or 6.1/7.1
operation, one of these modes, but not both, is available at any time. Ideal for playing music in
situations such as a party, this mode 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 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.
