Introduction
Your Receiver receiver provides all the key decoding and 
processing modes for analogue and digital signals, including 
the latest high definition audio formats over HDMI.
Modes for digital sources
Digital recordings are usually encoded to include 
information about their format type. The Receiver detects 
automatically the relevant format in a digital signal – such 
as Dolby Atmos, TrueHD, Dolby Digital Plus, DTS:X, DTS-HD 
Master Audio, Auro 3D, 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 definition 
formats) can be output in two mix modes, selected using the 
 button:
  Surround (e.g., five 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.
The Receiver stores the settings for each source. Thus 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
The following decoding and surround modes are for creating 
multi-channel stereo modes from 2-channel sources. They 
are available on the Receiver for standard and high definition 
Dolby Digital 2.0, DTS 2.0, PCM or analogue sources:
Stereo –
16 Channel Stereo –
Dolby Surround –
Dolby Virtual Height -
DTS Neural:X -
DTS Virtual:X -
Auro-matic 3D (AVR11, AVR21, AVR31, AV41) 
Stereo
In this mode the Receiver works as a conventional high 
quality audio amplifier. Note that if the subwoofer is enabled 
in stereo mode, then some processing of the signal is carried 
out.
  Stereo Direct: this achieves the most direct signal 
path if an analogue connection is present.
  16 Channel Stereo: this produces an output from 
all speakers by copying the left output to all left 
speakers and the right output to all right speakers. 
The centre speaker outputs a mix of left and right.
Dolby Surround
Dolby Surround allows the Receiver to derive up to  
16 outputs from a two or multi-channel source to take better 
advantage of all amplifiers and speakers in your setup.
Dolby Virtual Height
Dolby Virtual Height creates an immersive audio experience 
by virtualising height content over traditional speaker 
configurations without the need for height speakers. Note 
- this mode is NOT available if height speakers are selected.
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 
configurations without the need for height speakers. Note 
- this mode is NOT available if height speakers are selected.
Auro-matic 3D (AVR11, AVR21, AVR31, 
AV41)
Auro-matic 3D creates an immersive audio experience 
by creating additonal channels from the incoming audio 
to match the available output channels, enhancing the 
listening expereince.
Multi-channel source modes
Digital multi-channel source material is normally provided 
as ‘5.1 audio’. The ‘5.1 channels’ comprise of: left, centre 
and right front speakers, two surround speakers and a low 
frequency effects (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. The DTS-ES matrix enhanced decoding system 
creates one extra rear channel from information buried in 
the two surround signals of the 5.1 source. The ES enhanced 
system is sometimes referred to as a ‘6.1’ system. This 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, Auro 3D are high-resolution surround formats 
found on Blu-Ray discs
Decoding modes
The 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, Auro 3D are only available from the correct 
source material.
