Introduction
Your Receiver receiver provides all the key decoding
and processing modes for analogue and digital signals,
including the latest high denition audio formats over
HDMI.
Modes for digital sources
Digital recordings are usually encoded to include
information about their format type. e Receiver
detects automatically the relevant format in a digital
signal – such as Dolby Atmos, TrueHD, Dolby Digital
Plus, DTS:X, 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 Surround – needs to be selected manually.
Mode memory
Dolby Digital or DTS audio (including the high
denition 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 Surround, DTS Neural:X, etc.)
< Stereo.
e Receiver stores the settings for each source. us
the decoding mode for the following groups of source
material can be stored independently:
< Dolby Digital (multi-channel) and DTS source
material
< Two channel Dolby, PCM or Analogue source
material
Two-channel source modes
e following decoding and surround modes are for
creating multi-channel stereo modes from 2-channel
sources. ey are available on the AV860/AVR850/
AVR550/AVR390 for standard and high denition
Dolby Digital 2.0, DTS 2.0, PCM or analogue sources:
Stereo –
5/7 Channel Stereo –
Dolby Surround –
DTS Neural:X-
Stereo
In this mode the AV860/AVR850/AVR550/AVR390
works as a conventional high quality audio amplier.
Note that if the subwoofer is enabled in stereo mode,
then some processing of the signal is carried out.
< Stereo Direct: this achieves the best sound quality if
an analogue connection is present.
< 5/7 Channel Stereo: this produces an output from
all speakers by copying the le output to all le
speakers and the right output to all right speakers.
e centre speaker outputs a mix of le and right.
Dolby Surround
Dolby Surround allows the AV860/AVR850/AVR550/
AVR390 to derive up to 7.1.4 outputs from a two or
multi-channel source to take better advantage of all
ampliers and speakers in your setup.
DTS Neural:X
DTS Neural:X provides up to 12 channels of decoding
from stereo material. e AV860/AVR850/AVR550/
AVR390 will derive separate channels corresponding to
the standard home theatre layout.
Multi-channel source modes
Digital multi-channel source material is normally
provided as ‘5.1 audio’. e ‘5.1 channels’ comprise
of: le, centre and right front speakers, two surround
speakers and a low frequency eects (LFE) channel.
Since the LFE channel is not a full range channel, it is
referred to as ‘.1’.
Surround systems decode and reproduce the 5.1
channels directly. e DTS-ES matrix enhanced
decoding system creates one extra rear channel from
information buried in the two surround signals of
the 5.1 source. e ES enhanced system is sometimes
referred to as a ‘6.1’ system. is extra surround back
decoding
modes
channel is normally reproduced through two separate
loudspeakers, creating a ‘7.1’ system.
DTS-ES discrete is a true ‘6.1’ source, with six discretely
encoded channels, plus the ‘.1’ LFE channel.
Dolby Digital Plus, Dolby TrueHD, Dolby Atmos,
DTS:X and DTS-HD are high-resolution surround
formats found on Blu-Ray discs
Decoding modes
e modes given in the following table are available for
multi-channel digital sources.
Special modes such as DTS-ES 6.1 discrete, Dolby
Digital Plus, Dolby TrueHD, Dolby Atmos, DTS:X and
DTS-HD are only available from the correct source
material.
