540R v3

azur

ENGLISH

If no bitstream is present, pressing this button will result in the 540R v3

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.

For 5.1 Speaker setups the Dolby Digital/DTS Surround Modes button

will have a maximum of only one mode available which will depend on

the source material. See the following ‘Decode modes’ tables.

The Pro Logic/Neo:6/DSP modes button 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 Pro Logic 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 EX /

DTS ES 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 speaker setups, the number of decoding possibilities increases

as shown in the following ‘Decode modes’ tables. Several extra Post

Processing modes are available using Pro Logic II or IIx.

Incoming Dolby Digital/DTS streams are always shown on the front

panel display as Dolby Digital (x/x) or DTS (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

(2/1) - Left/Right stereo and LFE (Sub)

(2/2) - Left/Right stereo and Left/Right surround

(3/0) - Left, Centre, Right

(3/1) - Left, Centre, Right and LFE (Sub)

(3/2) - 5.1: Left, Right, Centre, Left Surround, Right Surround and LFE

(Sub)

(3/3) - 6.1: Left, Right, Centre, Left Surround, Right Surround, Surround

Back and LFE (Sub)

Operating instructions

To activate the 540R v3, 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 Input Mode button to select the input mode of

the source equipment, either analog or digital (depending on the

connection made on the rear panel).

The digital or analog icons on the display show which is the

currently selected input type.

Note: The 540R v3 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   540R   v3   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  540R  v3  returns  to
normal  operation  without  changing  mode.

Stereo Modes - Selects 2 channel Stereo operation for stereo material,

pressing again selects Stereo + Sub mode.

This is a digitally processed mode that allows bass and treble controls,

and sub generation if required. The input can be either analog (in which

case it will be turned into digital by 24 bit A/D conversion) or natively

digital.

Digital inputs can be connected to the SPDIF outputs from Tuner's or CD

Players etc (LPCM) or the digital outputs of DVD players (set to

Bitstream/Raw) playing 2-channel Dolby Digital (2/0) or DTS (2/0)

material.

Pro Logic/Neo:6/DSP modes - Selects a range of surround modes with

appropriate matrix encoded material.

These modes are for use with the analog or digital outputs from TV's or

VCR Players for instance if the source material has been encoded using

one of these processes.

Pro Logic 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

540R v3 the type of encoding used in the source material. Thus you

must manually select these modes.

Dolby Digital EX/DTS ES Modes - Selects a range of digital surround

modes with the appropriately digitally encoded material (only). These

modes are for use with the digital outputs (set to Bitstream/Raw) from

DVD players or satellite receivers etc. In order for the 540R v3 to allow

selection of these modes a valid input digital bitstream must be present.

This is because the 540R v3 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.
