Dolby Digital/DTS Modes - Selects a range of digital surround modes with the
appropriately digitally encoded material (only). These modes are for use with
the SPDIF, Toslink or HDMI digital outputs (set to Bitstream/Raw) from Blu-
ray players, DVD players or satellite receivers etc. In order for the 650R to
allow selection of these modes a valid input digital bitstream must be
present. This is because the 650R needs to read the incoming flags in order
to determine the type of decoding which can be used and present any
options that might be possible.
Note: Some new Surround Sound types (such as the Dolby and DTS HD) are
available only from Blu-ray disc over HDMI.
If no bitstream is present, pressing this button will result in the 650R
displaying “Mode Unavailable”.
Note: The modes available for each button depend both on the Speaker
Configuration that has previously been set in the OSD and on the source
material.
Pressing DD/DTS Modes button will cause the 650R to lock onto the
incoming bitstream and select the first available mode for the current
bitstream type.
In some circumstances (see tables) pressing the button again will switch to
an alternative decoding option.
Pressing the Prologic/ Neo:6/DSP modes button when the 650R has locked
to a DD/DTS bitstream will present more options where possible including
Post-Processed modes.
These are modes that allow extra processing to be applied after the main
surround-sound decoding. For instance Dolby Digital (2/0) + PLII Music.
Which adds a 5.1 ProLogic decode to a Stereo Dolby Digital decode to turn 2
channel stereo into 5.1.
This mode would be accessed by first selecting the Dolby Digital/DTS Mode
button with a Dolby (2/0) bitstream present (selects a normal Dolby Digital
(2/0) decode. Now press the Pro Logic/ Neo:6/DSP mode button to access
the next mode which adds a PLII decode on top.
For 6.1 or 7.1 Speaker setups, the number of decoding possibilities increases
as shown in the following ‘Decode modes’ tables. Several extra Post
Processing modes are available using either Prologic IIx or Neo:6.
Incoming Dolby Digital/DTS streams are always shown on the front
panel display as Dolby Digital (x/x).x or DTS (x/x).x, where the bracketed
numbers indicate the active channels in the source material. Active
output channels are shown by the icons on the right hand side of the
front panel display. Possible incoming DD/DTS types are:
(1/0)
- Mono, Centre channel only
(2/0)
- Left/Right stereo
(2/0).1
- Left/Right stereo and LFE (Sub)
(2/2)
- Left/Right stereo and Left/Right surround
(3/0)
- Left, Centre, Right
(3/0).1
- Left, Centre, Right and LFE (Sub)
(3/2).1
- 5.1: Left, Right, Centre, Left Surround, Right Surround and
LFE (Sub)
(3/3).1
- 6.1: Left, Right, Centre, Left Surround, Right Surround,
Surround Back and LFE (Sub)
(3/4).1
- 7.1: Left, Right, Centre, Left Surround, Right Surround,
Surround Back Left, Surround Back Right and LFE (Sub)
Operating instructions
To activate the 650R, switch the Power button on the rear panel to
On
then
press the
Standby/On
button on the front panel.
Selecting the source
1. Select the desired source by pushing the corresponding source button on
the front panel or remote control.
2. If necessary, press the
Audio Input Type
button to select the input mode of
the source equipment, either analogue, digital or HDMI (depending on the
connection made on the rear panel).
The digital, analogue or HDMI icons on the
display show which is the currently selected
input type.
Note: The 650R stores the input type for each source so that it is
automatically recalled when that source is selected again.
Selecting the desired listening mode
Select an appropriate mode for the source material/type you are listening to
by pressing one of the 3 main Digital Processing Options buttons and cycling
through sub-modes where available.
In all cases the first time a mode button is pressed the 650R will report the
current decoding mode on the front panel display. Pressing the button again
will then cycle to the next available mode (if there is one). If no button is
pressed for 4 or 5 seconds the 650R returns to normal operation without
changing mode.
Stereo Modes - Selects 2 channel Stereo operation for stereo material,
pressing again selects Sub mode.
This is a digitally processed mode that allows bass and treble controls, and
sub generation if required. The input can be either analogue (in which case
it will be turned into digital by 24 bit A/D conversion) or natively digital.
Prologic/Neo:6/DSP modes - Selects a range of surround modes with
appropriate matrix encoded material.
These modes are for use with the analogue or digital outputs from TV's or
VCR Players for instance if the source material has been encoded using one
of these processes.
ProLogic and Neo:6 are both available in various guises to decode
appropriately encoded soundtracks. Additionally DSP modes are available to
process sources with no encoding at all. Due to the matrix encoding process
none of these modes incorporate flags that tell the 650R the type of
encoding used in the source material. Thus you must manually select these
modes.
