Introduction
Your Receiver receiver 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 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
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 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 denition
Dolby Digital 2.0, DTS 2.0, PCM or analogue sources:
Stereo –
5/7 Channel Stereo –
Dolby Surround –
DTS Neural:X -
DTS Virtual:X -
Stereo
In this mode the AV860/AVR850/AVR550/AVR390
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 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
ampliers and speakers in your setup.
DTS Neural:X
DTS Neural:X is an advanced up-mixer that renders up
to 7.1.4 channels of immersive audio from nearly any
lower channel count content.
DTS Virtual:X
DTS Virtual:X creates an immersive audio experience
by virtualising height content over traditional speaker
congurations without the need for height speakers.
Note - this mode is NOT available if height speakers are
selected.

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 eects (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
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, 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,
DTS-HD and IMAX® ENHANCED are only available
from the correct source material.
