I'd been looking for years for some straightforward way to put 7.1 analog into BYPASS mode by switching all speakers to large and then be able to go back to all small for other inputs.

A while back someone here said they entered all the keystrokes into a programmable remote macro to go into the menu and switch all the speakers to large and then another to go back to all small. But you don't necessarily know which way the 990 is set when you turn it on, and it is not reversable with the same keystrokes to go back.

I have wondered if using the RS-232 port like a big HT controller or a computer can, could directly set all speakers to large or small directly.
