Operating the XMC-1
Note: some Matrix surround sound processing modes are not appropriate to use with certain
types of input signals, and some may conflict with certain other modes. for example, Dolby
plIIx may be used to transform stereo analog content into 5.1 channel or 7.1 channel surround
sound content, and may be used to transform 5.1 channel Dolby Digital or Dolby TruehD
content into synthesized 7.1 channel content, but cannot be used with 7.1 channel Dolby
TruehD content (because it is already 7.1 channels). The XMC-1 will oNly allow you the option
of choosing modes that are appropriate for your current signal source and mode.
How the XMC-1 Treats Content in Different Surround Sound Formats
The combination of Surround Sound decoding and Surround Sound processing the XMC-1 uses
for a given input signal will depend on the format of the incoming signal, and on how you have
configured the Surround Mode in the Setup Inputs Menu and Main Zone Menu.
The Setup Inputs Menu allows you to configure the default behavior independently for each input
for each type of input signal:
In Auto Mode - the XMC-1 will attempt to process the incoming signal to match the number of
speakers you have configured. For example, if your XMC-1 is configured for 5.1 speakers, a Dolby
TrueHD 5.1 channel input signal will be decoded to 5.1 channels, and a Dolby TrueHD 7.1 channel
input signal will be decoded to 7.1 channels, then mixed down to 5.1 channels. If your XMC-1
is configured for 7.1 speakers, a Dolby TrueHD 5.1 channel input signal will be decoded to 5.1
channels, then the surround channels will be processed with Dolby PLIIx to create a 7.1 channel
output optimized for your 7.1 channel system.
In Last Used Mode - the XMC-1 will use as it's default the same decoding and processing options as
were used the last time a similar signal was received on that input. (If, the last time a Dolby TrueHD
input was received on that input, you manually chose to listen in Stereo Mode, then Stereo Mode
will be the default the next time a similar signal is received on that input.)
You will also have the option of manually configuring an initial default mode for each input - for
each type of input signal which may be received. The specific options available will depend on the
type of input.
Regardless of what decoding and post processing modes are selected automatically by the
XMC-1, you will always be able to manually choose to use any combination of decoding and
processing modes that are appropriate for the type of input signal being received - either by using
the Mode Selector buttons on the front panel or remote control, or from the Main Zone Menu.
Note: Reference stereo Mode must be configured from the menu system; it cannot be selected
manually using the Mode Up/Down buttons.
Note: When the XMC-1 is configured for a single subwoofer, your subwoofer must be connected
to the XMC-1's left subwoofer output. When the XMC-1 is configured for a single rear surround
speaker, the same (monaural) surround signal is presented at both Rear surround outputs.
