CXR120/200
Operating instructions
To activate the CXR, switch the Power switch on the rear panel to On then
press the Standby/On button on the front panel.
Selecting the source
Select the source by using the Source +/- buttons on the front panel. After
4 to 5 seconds the CXR will select the new source, or it can be selected
by pressing the volume knob. The source selection buttons on the remote
control can also be used to directly select the source.
Selecting the desired listening mode
Select an appropriate mode for the source material/type you are listening to
by pressing the Stereo or Surround Modes button on the remote and cycling
through sub-modes where available.
In all cases the first time a mode button is pressed the CXR 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 CXR 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 analogue (in which case it
will be turned into digital by 24 bit A/D conversion) or natively digital.
Surround Modes – Selects a range of digital surround modes for the
appropriately digitally encoded material
Note: Some Surround Sound types (such as Dolby TrueHD and DTS HD) are
available only from Blu-ray disc over HDMI.
In some circumstances (see tables) pressing the button again will switch to
an alternative decoding option.
Dolby Pro Logic and DTS 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 CXR the type of encoding
used in the source material. Thus you must manually select these modes.
Pressing the Surround Modes button when the CXR has locked to a Dolby
Digital/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) + Dolby Pro Logic
II Music. Which adds a 5.1 Dolby Pro Logic decode to a Stereo Dolby Digital
decode to turn 2 channel stereo into 5.1.
For 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 Dolby Pro Logic IIx or DTS 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.
