Input Settings
The SP4 permits the installer to create access to
sources in a very intuitive way for the end user. The
installer is advised to title inputs thoughtfully and
without ambiguity. No longer must an end user
remember which physical input is attached to a
particular source component. Further, only inputs
specifically configured as ACTIVE will be available
from the remote control. Finally, multiple inputs
can be created from a single source component
for the purposes of loading separate settings. For
example, you may have an input titled 'CD Music'
that accesses a Blu-Ray player attached to HDMI 7
that by default downmixes everything to stereo and
another input titled 'Blu-Ray Movie' that accesses
the same source component but upmixes all audio
to Dolby Surround.
1. Active
Any input with a blue Y is accessible from remote
controls. To disable access to an input, click the
Y and it will change to an N and gray out the
entire row thereby disabling access to this input.
You are advised to disable any input with no
source component attached.
2. Input
This is the name of the input that will appear
in remote control applications. By default, the
name is the same as the default audio input. You

may type in this box and change the name to
something more intuitive. Supports a maximum
of 10 characters.
3. Video In
For any given input, you can map separate video
and audio inputs except that when the audio
input is an HDMI input, the video input must be
the same HDMI input. None may also be chosen
when no video is desired.
4. Audio In
For any given input, you can map separate video
and audio inputs except that when the audio
input is an HDMI input, video must be the same
HDMI input. None may also be chosen when
no video is desired. Note that the analog input
matrix may be selected as a particular stereo
pair or as a 7.1 input.
5. Preferred Upmix
On a per input level, you may choose to engage
a particular upmixer, or leave the option set to
none. This setting overrides any preferred upmix
defined as part of a preset. So, if a preset is to
be used in conjunction with this input, and that
preset includes specifying an upmix, leave this
setting to None.
6. Trimmer
Each input may have the audio attenuated by a
