Re: Managing/Processing volume
|
I just prefer to use the volume control modules available in the crestron database rather than AINC.? They already have memory for 4 volume presets built in. ? The point was that raise and lower on the AVR modules kind of sucks and they do not have an analog volume level input, so I found a way to send the direct level to the AVR precisely because it allows the AVR to be controlled like a crestron device. ? The outputs of the analog step could be connected to an EQU to and SIO to send the discrete steps. As an analog you can store it like any other signal.
As you stated, you could just use a raise/lower if the AVR has that feature and process?the feedback for user display and to store for preset/zone presets that are then decoded on recall. Lots of ways to do this.
The analog increment allows you to not deal with the rounding issues. You could always store the converted % amount and convert backed to your signed values on a preset recall. ?

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...:(
