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.

an analog input or a digital input with PCM or Dolby Digital 2.0 recordings is in use. The

Dolby 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 mode creates compelling five-channel surround sound from
conventional stereo recordings.
DOLBY PRO LOGIC IIx Dolby Pro Logic IIx is the latest extension of Dolby Pro Logic II technology that creates a discrete

so that the sound field is enhanced by adding back surround
channels, as well as to enable the

a six channel direct input may be used as a source for the remote room.
Logic 7 Cinema
Exclusive to Harman Kardon for AV receivers, Logic 7 is an advanced mode that extracts the

material. Depending on the number of speakers in use and the selection made in the
SURROUND
SELECT
menu, the “5.1” versions of Logic 7 modes are available when the 5.1 option is chosen,
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.
