[Frost Neil <Neil.Frost@xxxxxxx>]

Keith,

Will the volume be IR or hardwired or both?

Well.... I havent said it in this thread yet but....

in the past I have mentioned the KAT5 switcher and the fact that it is
being
designed with HA integration in mind. One feature will be Audio and
Video
overlay to allow HomeVision to display caller ID etc or play WAV files
over
the top of the audio either with attenuation or complete muting of the
original source.

The Whole House audio features will have remotely controllable volume.

As always .... I cant say exactly when :-(
