19.3 Channel Schemes and Speakers
Channel schemes describe the speakers employed by each
decode mode. They are expressed by terms such as “5.1” or
“3/2.1” Taking 5.1 as an example, the “5” refers to the number
of conventional speaker channels and the “.1” refers to a sub-
woofer. In 3/2.1 the “3” refers to the number of front channels
employed (in this case, left, right and centre), the “2” refers to
the number of surround channels and the “.1” refers to a sub-
woofer. With appropriately encoded digital programme material
channel schemes are displayed by the AV2 when decode modes
and inputs are selected (if a signal is present).
Note:
The “direct” option available to analogue inputs routes
the signal directly to the output volume control, switching off and
bypassing any signal decoding. This is distinct from the “stereo”
decode option which digitises the incoming signal and uses internal
processing to control speaker channel routing.
Note:
Most decoding options and choices are self evident - a Dolby
Surround encoded movie signal (either digital or analogue) should
be decoded in Dolby Pro Logic Movie II mode for example.
Note:
DTS Neo:6, DTS-ES, and DTS Matrix can only be selected if
extra rear speakers are specified. If no such speakers are present
then DTS-ES Discrete encoded material will be decoded as DTS
3/2.1.

Table 19.4
Decode Table - Selection, Availability and Display
Note:
The continual
development of decoding
technologies means that your
AV2 may offer and display
some further or alternative
decode options. If this
appears to be the case please
visit www.naim-audio.com
and download the latest AV2
manual.
Note:
The channel scheme displayed by the AV2 for auto decoding
of digital material may depend on the specific scheme encoded
within the material. Schemes other than those shown in the table
above are possible.
Note:
Dolby Pro Logic and DTS Neo:6 decoding can be applied
to conventional analogue or digital stereo audio (CD for example).
Results however will be variable because effects, centre or sub-
woofer information is not usually encoded in conventional stereo
programme material in the first place. Conversely, DTS, Dolby
Surround or Dolby Digital Surround programme material decoded
to conventional stereo or mono will reproduce satisfactorily without
significant loss of programme information.
