Logic 7 Cinema
Logic 7 Music
Logic 7 Enhance
Exclusive to Audioaccess for receivers, Logic 7 is an advanced mode that extracts the
maximum surround information from either surround-encoded programs or conventional
stereo material. When your system has been configured for use with Surround Back
Speakers (see: AVR21EN Configuration/Speaker Setup), you may choose between either
7.1 or 5.1 versions of the Logic 7 modes, while only the 5.1 versions are available when
there are no Surround Back Speakers. 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 soundstage 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. The Logic 7 E (or Enhance)
mode, available only when the 5.1 option is chosen, is an extension of the Logic 7 modes
that is primarily used with musical programs. Logic 7 adds additional bass enhancement that
circulates low frequencies in the 40Hz to 120Hz range to the front and surround speakers to
deliver a less localized soundstage that appears broader and wider than when the subwoofer
is the sole source of bass energy.
DTS Neo:6 Cinema
DTS Neo:6 Music These two modes are available with analog sources playing to create a three-channel, five-
channel or six-channel surround presentation from matrix-encoded or stereo sources. Select
the Cinema version of Neo:6 when a program with matrix surround encoding is present.
Select the Music version of Neo:6 for optimal processing when a nonencoded, two-channel
stereo program is being played.
Theater
The Theater mode creates a sound field that resembles the acoustic feeling of a standard
live performance theater.
Small Concert,
Medium Concert The two Hall modes create sound fields that resemble a small- (Small Theater) or medium-
sized (Medium Theater) concert hall.
Dolby
VirtualSpeaker
Reference
Wide Dolby Virtual Speaker uses advanced technology to simulate the sonic signature of a
speaker location even when there is no speaker physically present in that location. The
Reference (“REF”) mode activates any missing speakers to simulate a 5.1 presentation with
accurate localization. The Wide mode virtualizes the locations of the front-channel speakers
to create a wider image and a more enveloping sound field. It is available no matter how
many speakers are present.
5-Channel Stereo
7-Channel Stereo
These modes take advantage of multiple speakers to place a stereo signal at both the front
and back of a room. They places the same signal at the front-left and surround-left, and
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) This mode turns off all surround processing and presents the pure left- and right-channel
presentation of two-channel stereo programs. When
SURROUND OFF
is selected, the unit
is in a “bypass” mode with no bass management. When
SURROUND OFF+DSP
is selected,
the signal is digitized and bass management settings are applied.
Dolby Headphone
DH1
DH2
DH3
BP
Dolby Headphone enables ordinary stereo headphones to portray the sound of a five-
speaker surround-playback system. The DH1 mode creates headphone presentation that
resembles a small, well-damped room and is appropriate for use with both movies and
music-only recordings. The DH2 mode creates a more acoustically live room particularly
suited to music listening. The DH3 mode creates a larger room, more like a DH3 concert hall
or movie theater. The BP (Bypass) mode turns off all surround processing to the headphone
jack.

Dolby Digital
Dolby Digital is a standard part of DVD, and high-definition (HDTV) broadcasts and is available
on specially encoded LD discs and satellite broadcasts.
An optional, external RF demodulator is required to use the AVR21EN to listen to the Dolby
Digital soundtracks available on laser discs. Connect the RF output of the LD player to the
demodulator and then connect the digital output of the demodulator to the
Optical [circle 24,
square 13] or Coaxial Inputs [circle 19, square 16] of the AVR21EN. No demodulator is
required for use with DVD players or DTS-encoded laser discs.
