There are an additional 4 audio-only devices and then 4 more "special purpose" devices (XM, tuner, etc.).
In theory, you could connect 7 A/V inputs, but you would would be constantly remapping the inputs (not hard to do, but it'd be a pain if you had to do it all the time).
Maybe someone else has a different take on this (hope so!). It seems really odd that Yamaha would provide the front-end capability for 7 devices and then limit the selector to 6.
It's likely possible to piggyback more devices using the S-Video/composite inputs, though. I haven't tried this, and these inputs are not remappable. But, you could conceivably wire a device into the DVD input (input "I") using S-Video and stereo composite audio and still have the "I" input mapped to HDMI, for instance. In this case, the unit should revert to the S-Video and composite audio if the HDMI device is turned off. Just a guess, though.
I wonder if the Denon handles things differently.
Anyone got a better take on this? (Just curious at this point.)
The 3800 allows you to physically connect 7 high-definition A/V sources using the 4 HDMI and 3 component connections. Which of these physical connections is selected as input is user-mappable on to the A/V input selectors. Each A/V selector may be mapped to 1 HDMI input, 1 component input, or 1 HDMI input and 1 component input. When two physical connections are mapped to the same A/V selector, the HDMI connection takes priority. If the HDMI source is off, the source connected by component becomes the input.
For example I have things set up as follows:
BD/HD DVD --> HDMI-1: BluRay player, Component-A Satellite Box2
DVD --> HDMI-2: HD-DVD player
DTV/CBL --> HDMI-3: Satellite Box1
DVR --> HDMI-4: AppleTV
Then when I select BD/HD DVD input, if the BluRay player is on, it becomes the input. If it is off, Satellite Box2 is the input. No further remapping is necessary, just keep the inputs you don't want selected, OFF.
The S-Video and composite inputs are not remappable.
Because the input selectors can be remapped and renamed quite freely, there doesn't need to be a strict association between A/V type input selectors on the remote and the physical sources.
Hope that's clear.
