MODEFEATURES
DOLBY DIGITALAvailable only with digital input sources encoded with Dolby Digital data. It provides up to
five separate main audio channels and a special dedicated Low Frequency Effects channel.
DOLBY DIGITAL EXAvailable when the receiver is configured for 6.1/7.1 channel operation, Dolby Digital EX is the
latest version of Dolby Digital. When used with movies or other programs that have special
encoding, Dolby Digital EX reproduces specially encoded soundtracks so that a full 6.1/7.1
soundfield is available.When the receiver is set for 6.1/7.1 operation and a Dolby Digital signal is
present, the EX mode is automatically selected. Even if specific EX encoding is not available to
provide the additional channel, the special algorithms will derive a 6.1/7.1 output.
DTS 5.1When the speaker configuration is set for 5.1-channel operation, the DTS 5.1 mode is
available when DVD, audio-only music or laserdiscs encoded with DTS data are played.
DTS 5.1 provides up to five separate main audio channels and a special dedicated
low-frequency channel.
DTS-ES 6.1 MatrixWhen the speaker configuration is set for 6.1/7.1 operation, playback of a DTS-encoded program
DTS-ES 6.1 Discretesource will automatically trigger the selection of one of the two DTS-ES modes. Newer discs with
special DTS-ES discrete encoding will be decoded to provide six discrete, full-bandwidth channels
plus a separate low-frequency channel. All other DTS discs will be decoded using the DTS-ES Matrix
mode, which creates a 6.1-channel sound field from the original 5.1-channel soundtrack.
DOLBY PRO LOGIC II Dolby Pro Logic II is the latest version of Dolby Laboratory’s benchmark surround technology
MOVIEthat decodes full-range, discrete left, center right, right surround and left surround channels
MUSICfrom matrix surround encoded programs and conventional stereo sources when
DOLBY PRO LOGIC an analog input or a digital input with PCM or Dolby Digital 2.0 recordings is in use.The
GAMEDolby Pro Logic II Movie mode is optimized for movie soundtracks that are recorded with matrix
surround, by creating separate center, rear left and rear right signals. while the Pro Logic II Music
mode should be used with musical selections that are recorded with matrix surround or even with
normal stereo mode, creating separate rear left and rear right signals in any case. The Pro Logic II
mode creates compelling five-channel surround sound from conventional stereo recordings. Game
mode ensures that special effects are routed to the surround channels, while delivering their full
impact using the subwoofer, thus fully immersing the game player in the universe of the video game.
DOLBY PRO LOGIC IIx Dolby Pro Logic IIx is the latest extension of Dolby Pro Logic II technology that creates a discrete
MUSIC6.1 and 7.1 sound field from matrix surround or two-channel stereo sources in systems
MOVIEconfigured for surround back speakers. Both Movie and Music versions of Pro Logic IIx are
GAMEavailable. Movie, Music and Game versions of Pro Logic IIx are available. Game mode ensures that
special effects are routed to the surround channels, while delivering their full impact using the
subwoofer, thus fully immersing the game player in the universe of the video game.
Logic 7 CinemaExclusive to Harman Kardon for AV receivers, Logic 7 is an advanced mode that extracts the
Logic 7 Musicmaximum surround information from either surround-encoded programs or conventional stereo
Logic 7 Enhancematerial. Depending on the number of speakers in use and the selection made in the
SELECT
while the “7.1” versions of Logic 7 produce a full sound field presentation, including back surround
speakers when the “6.1/7.1” option is chosen. 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 former 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 is an extension of the Logic 7 modes that is
primarily used with musical programs and is available with the 5.1 surround mode option selected
only. Logic 7 E 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.
menu, the “5.1” versions of Logic 7 modes are available when the 5.1 option is chosen,

MODEFEATURES
DTS Neo:6 CinemaThese two modes are available when any analog source is playing to create a six-channel
DTS Neo:6 Musicsurround presentation from conventional Matrix-encoded and traditional Stereo sources. Select
the Cinema version of Neo:6 when a program with any type of analog 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.
When selecting a DTS Neo:6 Cinema mode, a 3-, 5- or 6-channel configuration may be available,
depending on the number of speakers in your system. Use 3-channel mode when only a front left and
right and a center speaker are present; surround-channel information will be mixed into these speakers.
The 6-channel mode will only be available if you have configured your surround back speakers as active.
DTS 96/24 DTS 96/24 is a high-resolution format that uses a 96kHz sampling rate with 24 bits to produce extended
information that improves the harmonics of the source material. The AVR is capable of automatically detecting
and decoding DTS 96/24 materials and delivering them as the artist intended.
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.
Dolby Virtual Speaker Dolby Virtual Speaker technology uses a next-generation advanced algorithm to reproduce the dynamics and surround
Referencesound effects of a precisely placed 5.1-channel speaker system using only front left and right speakers. In the
WideReference Mode, the apparent width of the sound across the front image is defined by the distance between the two
speakers.The Wide Mode provides a wider, more spacious front image when the two speakers areclose together.
THEATERThe 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 1The two Hall modes create sound fields that resemble a small (HALL1) or
HALL 2medium sized (HALL 2) concert hall, with stereo and even pure mono sources.
VMAx NearWhen only the two front-channel loudspeakers are used, Harman’s patented VMAx mode
VMAx Fardelivers 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 4.When headphones
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 StereoThis mode takes advantage of multiple speakers to place a stereo signal at both the front and
7-Channel Stereoback 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 presentation of
Surround Off (Bypass) two-channel stereo programs. The Surround Off (Bypass) mode may only be used with analog source inputs,
DSP Surround Off 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.
Dolby Headphone Dolby Headphone enables ordinary stereo headphones to portray the sound of a five-speaker
DH1 surround-playback system. The DH1 mode creates headphone presentation that resembles a small,
DH2 well-damped room and is appropriate for use with both movies and music-only recordings.
DH3 The DH2 mode creates a more acoustically live room particularly suited to music listening.
34 OPERATION
The DH3 mode creates a larger room, more like a concert hall or movie theater.

Processor Reset
In the rare case where the unit’s operation or the
displays seem abnormal, the cause may involve
the erratic operation of the system’s memory or
microprocessor.
To correct this problem, first unplug the unit from
the AC wall outlet and wait at least three
minutes. After the pause, reconnect the AC
power cord and check the unit’s operation. If the
system still malfunctions, a system reset may
clear the problem.
To clear the AVR’s entire system memory including tuner presets, output level settings, delay
times and speaker configuration data, first put
the unit in Standby by pressing the SystemPower Control button
the Tone Mode button
The unit will turn on automatically. Note that
once you have cleared the memory in this manner,
it is necessary to re-establish all system configuration settings and tuner presets.

for three seconds.
NOTE: Resetting the processor will erase any
configuration settings you have made for
speakers, output levels, surround modes, digital
input assignments as well as the tuner presets.
After a reset the unit will be returned to the
factory presets, and all settings for these items
must be reentered.
If the system is still operating incorrectly, there
may have been an electronic discharge or severe
AC line interference that has corrupted the
memory or microprocessor.
If these steps do not solve the problem, consult
an authorized Harman Kardon service depot.
