I send the discrete volume level to the AVR.? It is much easier to deal with it that way.? Use a volume control module to generate analog value then use a bit of logic to send it.? Plus is it is then able to be treated the same as a Crestron device (SWAMP, PAD-8 . . .) and you can do the memorize preset volumes thing, initialize to a start-up level, or whatever other joy-joy stuff you might do with a multi-zone system.? Even though most of the Crestron modules I have seen use raise and lower, virtually all AVRs or processors that allow third party control allow setting volume level directly.

?

For serial control of Aventage the volume direct format is @MAIN:VOL=11.0\n or @MAIN:VOL=-11.0\n.?

I ASCALEL the raw volume level.? 0%,100% scales to -80, 16 (or reduce the output range to something like -50, 0 to set the volume of the AVR to a barely audible minimum and limit the top end, similar to VolMin and VolMax inputs on the PAD8.)

I EQU the scaled level to get a signal for each level command. ?The digitals out of EQU drive SIO.

I also use AOS (* output) on the TX$ for the AVR to do a 0.2 sec disable of the EQU to allow the AVR to process the command before sending the next during ramping.

Re: dB display - our normal clients barely understand %, dB would confuse them even more!!? HaHa!!

Re: adding the two extreme values:
I'll look at that, but I think that the basic issue is analog values being slightly different when scaled vs. our level analogs.


The root problem is that we have a consumer piece that uses Pro Audio parameters...:(
