ENGLISH
Movie and game producers can also mix specific additional height channels
into a 2ch, 5.1 or 7.1 soundtrack, which Dolby Pro Logic IIz will then decode as
a post process.
If it is desired to use Dolby Pro Logic IIz, you should set the 651R/751R to 5.1
+ Height mode, connect two speakers to the SBL and SBR outputs and
physically position them above your left and right front speakers, then select
Dolby Pro Logic IIz post processing. See later section.
A DTS technology which is able to recreate 6 channel (Left Front, Right Front,
Centre, Left Surround, Right Surround, Surround Back ) surround sound from
suitable analogue matrix encoded stereo source material. DTS Neo:6
material can be played back by normal Stereo equipment (as Stereo) or
decoded into 7.1 by sending the Surround Back decode to the both the
Surround Back Left and Right speakers (forming two mono Back Surrounds).
Note: Neo:6 does not include a Low Frequency Effects channel for the
Subwoofer, but the 651R/751R can create a Subwoofer output via Bass
management. Refer to the ‘Tone/Sub/LFE configuration’ section in the
‘Operating instructions’ part of this manual.
A DTS technology that provides 5.1 channels of 96kHz / 24bit audio (along
with video if required) on DVD-Video and DVD-Audio (video zone) discs (when
suitably encoded in DTS 96/24). DVD players which allow 'DTS digital out'
pass the DTS 96/24 bitstream over S/P DIF or HDMI for decoding in the
651R/751R.
DSP modes
These modes allow a surround-sound experience from source material that
has no encoding at all. The surround sound effect is achieved by Digital
Signal Processing of the Analogue or Digital stereo source used. Two modes
are possible: Movie and Music.
Stereo/Stereo + Sub
Only the Front Left and Front Right speakers (and subwoofer if selected)
have output in this mode. If an analogue source is selected it will be
converted to digital via 24 bit A/D converters to allow digital domain sub
creation and bass/treble controls.
If a digital source is selected the 651R/751R will be processing either LPCM
stereo (from the digital outputs of a CD player for instance) or a Stereo downmix
of DD or DTS material (from the digital output of a DVD player for instance).
Other modes
Analogue stereo direct
Selects the analogue inputs for the current source directly with no A/D
conversion, DSP processing, Bass/Treble or subwoofer channel active.
Provides the very best fidelity for analogue Hi-Fi source equipment. In this
mode the 651R/751R is acting just like a normal Hi-Fi integrated amplifier.
Multi channel PCM
Some playback devices (in particular Blu-ray players) are able to decode some
of the above formats themselves internally and then output the decoded
audio as Multi Channel PCM to the 651R/751R. In addition Blu-ray disks can
support native unencoded Multi Channel PCM soundtracks (of up to 8
channels) on the disc itself. In either case if your player can output these over
HDMI the 651R/751R is able to receive them in Multi-Channel PCM mode.
Multi channel stereo
For Stereo inputs the 651/751R can if required create a multi-channel
stereo presentation whereby the incoming Left and Right channels are
output to the Front Left/Surround Left/Surround Back Left and Front
Right/Surround Right/Surround Back Right channels respectively. The
Centre is sent a L+R signal and a mono-ised Subwoofer channel is also
created.
Known also as DD (3/3) or DD 6.1, an enhanced form of Dolby Digital. On top of
the discretely encoded 5.1 channels DD EX provides an extra 6th channel
(Surround Back, giving 6.1) matrix encoded into the rear surrounds for greater
image depth and more solid sound localisation behind the listener. DD EX requires
a DD EX encoded disc. DD EX is backwards compatible with DD 5.1 decoding. If
DD EX is decoded as normal DD the Surround Back signal will be present in both
Left and Right Rear Surrounds (forming a phantom rear centre). It can also be
decoded as 7.1 by sending the Surround Back decode to both the Surround Back
Left and Right speakers (forming two mono Back Surrounds).
Known also as DTS (3/3) Matrix, an enhanced form of DTS. On top of the discretely
encoded 5.1 channels DTS ES also provides an extra 6th channel (Surround Back
giving 6.1), matrix encoded into the rear surrounds for greater image depth and
more solid sound localisation behind the listener. DTS ES requires a DTS ES
encoded disc. DTS ES material is backwards compatible with DTS 5.1 decoding. If
DTS ES is decoded as normal DTS the Surround Back signal will be present in both
Left and Right Rear Surrounds (forming a phantom rear centre). It can also be
decoded as 7.1 by sending the Surround Back decode to the both the Surround
Back Left and Right speakers (forming two mono Back Surrounds).
Another enhanced form of DTS, also known as DTS (3/3) Discrete or DTS ES
Discrete 6.1. DTS ES Discrete also provides an extra channel (Surround
Back) for greater image depth and more solid sound localisation behind the
listener, however in this case extra data is included in the bitstream so that
all channels are discretely encoded. The Surround Back has greater
separation from the other channels than is possible with matrix encoded
technologies. DTS-ES Discrete requires a DTS-ES Discrete encoded disc.
DTS ES Discrete is backwards compatible with both DTS 5.1 and DTS ES
Matrix 6.1 decoding. If DTS ES Discrete is decoded as normal DTS the
Surround Back signal will be present in both Left and Right Rear Surrounds
(forming a phantom rear centre). If DTS ES Discrete is decoded with DTS ES
Matrix the Surround Back signal will be decoded separately (i.e. as 6.1) but
by a matrix process, which will give the same channel separation as if the
source disc were actually DTS ES Matrix (but not as good as DTS EX
Discrete).
It can also be decoded as 7.1 by sending the Surround Back decode to both
the Surround Back Left and Right speakers (forming two mono Back
Surrounds).
The replacement for the original Dolby Pro Logic, Dolby Pro Logic II is a
technology where 5 channels (Front Left, Front Right, Centre, Surround Left,
Surround Right) are encoded into a Stereo mix by an analogue matrix
process. Dolby Pro Logic II material can be played back by normal Stereo
equipment (as Stereo) or decoded into 5 channel surround-sound.
Dolby Pro Logic II is compatible with the earlier 4 channel (Left, Centre, Right
and mono Surround) Dolby Pro Logic system (which was the decoding
counterpart to Dolby Surround encoding) as used widely on Video tapes, TV
broadcasts and earlier films.
Note: Dolby Pro Logic does not include a Low Frequency Effects channel for
the Subwoofer, but the 651R/751R can create a Subwoofer output (for 5.1)
via Bass management. Refer to the ‘Tone/Sub/LFE configuration’ section in
the ‘Operating instructions’ part of this manual.
A newer version of Dolby Pro Logic II which is able to recreate 7 discrete
surround sound channels from suitable encoded stereo source material.
Dolby Pro Logic IIx also has modes for post processing either Stereo material
or 5.1 material into 7 channels whether or not it has been Dolby Pro Logic IIx
encoded. When 5.1 decoding is required, Dolby Pro Logic II decoding will
always be used by the 651R/751R in place of Dolby Pro Logic IIx as IIx only
works for 7 channel output.
Note: Dolby Pro Logic IIx does not include a Low Frequency Effects channel
for the Subwoofer, but the 651R/751R can create a Subwoofer output (for
7.1) via Bass management. Refer to the ‘Tone/Sub/LFE configuration’
section in the ‘Operating instructions’ part of this manual.
A new Dolby matrix technology that delivers additional height channels
positioned above the front left and right speakers. Dolby Pro Logic IIz identifies
spatial cues that occur naturally in most content plus ambient sound and
amorphous effects such as rain or wind and directs them to additional front
height speakers.
