Hi Guys,
I have the Denon AVR-X4500H. I do wish the amp section could shut down when using external amp like the newer models but other than that it is great. Although this is my second as the first had terminal failure about 2 weeks in.

The current code works to short press for minimum increase (0.5db) and hold for continuous increase but the increase rate on hold is very fast and hard to get just right. I think half speed would be about right. I'll try doubling the 0679 individually and in combination to see what I get.

Thanks for the help. I'll let you know how it turns out.
H
