Dayton Amplifiers with RS232 Port

[huh]

Anyone have any experience with the Dayton amplifiers such as this one:

I don't see the RS232 codes in the owners manual...  and $700 is a steep price until you consider it's a 6 channel amplifier.

Did a wiki and forum search and don't see anything.

Look at Denon amps. They come cheaper, especially the older ones without or very few HDMI ports. Some of them are 5.1 others 7.1, so plenty of channels.
