Arcam AVR500 Home Theater System User Manual

Your AVR500/AVR600 receiver or AV888 pre-amp
provides all the key decoding and processing modes for
analogue and digital signals, including the latest high
denition audio formats over HDMI.
Modes for digital sources
Digital recordings are usually encoded to include
information about their format type. e unit detects
automatically the relevant format in a digital signal –
such as Dolby TrueHD, Dolby Digital Plus, DTS-HD
Master Audio, Dolby Digital, or DTS – and switches in
the appropriate decoding.
Modes for analogue sources
Analogue recordings do not contain information about
their encoding formats, so the desired mode – such as
Dolby Pro Logic – needs to be selected manually.
Mode memory
Dolby Digital or DTS audio (including the high
denition formats) can be output in two mix modes,
selected using the MODE button:
< Surround (e.g., ve main channels plus a subwoofer
for a 5.1 source)
< Stereo downmix.
Two-channel audio, regardless of whether it is analogue
or digital can also be output in two mix modes, selected
using the mode button:
< Surround (e.g., Dolby Pro Logic II Movie, Neo:6
Music, etc.)
< Stereo.
eAVR500/AVR600/AV888 stores the settings for each
source (except MCH). us the decoding mode for
the following groups of source material can be stored
< Dolby Digital (multichannel) and DTS source
< Two channel Dolby, PCM or Analogue source
Two-channel source modes
e following decoding and surround modes are
available for standard and high denition Dolby Digital
2.0, DTS 2.0, PCM or analogue sources:
Pro Logic II Movie
Pro Logic II Music
Pro Logic II Game
Pro Logic IIx Movie
Pro Logic IIx Music
Pro Logic IIx Game
Pro Logic
Neo:6 Cinema
Neo:6 Music
Pro Logic IIx modes are only selectable when
Surround Back speakers are present.
In this mode the unit works as a conventional high
quality audio amplier. Note that if the subwoofer is
enabled in stereo mode, then some processing of the
signal will be carried out. To achieve ultimate sound
quality with analogue sources, select the Stereo Direct
function if an analogue connection is present.
Dolby Pro Logic II
Dolby Pro Logic II decoding is designed to produce ve-
channel output from two-channel source material.
ere are three dierent modes available in Pro Logic II:
‘Movie’, ‘Music’ and ‘Game’ modes, which are intended
for use as their names suggest. Due to the dierent
recording methods used for movies, music and video
games, it is recommended that the correct decoding
mode for your source material is used to obtain best
< Movie mode: is is intended for use with
‘cinematic’ material, which is mixed and monitored
in a calibrated multichannel environment. Movie
mode is a ‘xed’ mode that is designed to give a
similar sound when listening using a home cinema
system to that obtained in a cinema.
< Music mode : Stereo music is not designed for
surround processing, although good surround
eects can be obtained through careful production.
As the optimum decoding method varies according
to the recording, Music mode allows the user
adjustment of the processing characteristics.
< Game mode: Video games today are extremely
sophisticated, with dramatic 5.1 surround
audio tracks. Game mode gives augmented bass
management to capture the full eect of game
sounds panned to the surrounds, ensuring the
bass impact from purer surround eects are fully
delivered to the subwoofer.
Dolby Pro Logic IIx
Dolby Pro Logic IIx is an extension of the Dolby Pro
Logic matrix-decoding method. e decoder allows
the processor to derive seven outputs from a two or
multichannel (up to 5.1 with EX) source to take better
advantage of all ampliers and speakers in a 7.1 setup.
As with Pro Logic, there are three dierent modes
available: Movie, Music and Game. Due to dierent
recording methods used for movies and music, you
should select the correct mode for your source material.
Dolby Pro Logic
Dolby Pro Logic is a legacy mode that is designed
to produce a ve-channel output from two-channel
source material. It should be used only when the source
material is encoded as Dolby Pro Logic; otherwise,
we recommend the use of Dolby Pro Logic II. is is
because Pro Logic processing on straight stereo sources
can sound mued and compressed.
DTS Neo:6
DTS Neo:6 provides up to six full-band channels of
decoding from stereo material. e AVR500, AVR600
or AV888 will derive separate channels corresponding to
the standard home theatre layout.
< Cinema : A movie mode designed to reproduce a
movie theatre environment. Neo:6 technology allows
various sound elements within a channel or channels
to be steered separately, and in a way which follows
the original presentation naturally.
< Music : A music mode designed to produce a lively,
high-integrity surround-eect from most two-
channel music sources from all available speakers.
Neo:6 music mode expands stereo recordings into
the ve or six-channel layout without diminishing
the subtlety and integrity of the original stereo
