A typical listening session might go something like this: You press the “CD” Master Key
and the system comes to life correctly configured to Stereo Mode. After listening for a
while, you decide that one of your processor’s digital sound fields would be very well
suited to the CD you are listening to. You press the “Surround Sound” Master Key and
experiment with different modes until the sound is perfect.
However, if the user decides to skip a song on the CD, you simply reselect the “CD”
Master Key to access the song skip button. Normally this would reset the system to
Stereo, but since the “Surround Sound” Master Key was programmed as a “Feature Key”,
the IntelliFile II’s “Automation Bypass” feature is engaged, and the preamp will not be reset
to Stereo mode.
Since the “CD” Master Key was the last source selected before pressing the “Surround
Sound” Master Key, the normal steps the CD Master Key would trigger to reset the
surround mode to “Stereo” are bypassed. If you were to press any of the other Master
Keys (rather than the last selected, which would be “CD” in this example), the automation
would not be bypassed and the system would continue with normal operation and
configure the system to the default surround mode for that newly selected Master Key.
How to Program “Component Power” for Multiple Master Keys which Share a
Common Source
It is possible to use more than one Master Key to automatically turn on and control the
same source. One example might be multiple Master Keys (labeled HBO, Showtime,
Disney, ESPN, etc.) that are all turning on and controlling the same DSS receiver.
However, the ending sequence for each of the Master Keys is programmed to select a
different channel.
Another example would be a system with a Pioneer combination DVD, Laser and CD
player. You would label three Master Keys for the three functions in the machine, so that
you can program the Surround Sound Mode to be “Dolby Digital” when the DVD key is
pressed, “Dolby ProLogic” when the Laser Disc key is pressed, and “Stereo” when the CD
key is pressed.
There is an “Installation Trick” and a “Programming Trick” which need to be performed in
order for the component to turn on and off as the end-user would expect:
Installation Trick
You must split the shared source component’s sync output to each of the appropriate sync
connections for each Master Key that will be used to automate and control the shared
component. This will enable the MSU to accurately monitor the sync status of the shared
source from any of the Master Keys.
