This is a feature request, but before making it formally, I'd like to get feedback as to its usefulness.

I read the SHD manual and it looks like Dirac and Backend presets are locked together. This rather makes sense.

But there appears to be no way to set a preferred input or volume level (and whether fixed or variable per preset) or whether it can be changed while that preset is selected. (Max volume would be nice as well).

Here's my scenario: I want to combine a Dirac Live - corrected 7.1 theatre setup with a high resolution two channel setup. I can dedicate separate sub pairs to stereo (left and right subs) and theatre (LFE and bass managed). So, I'd like to have two inputs to an SHD: digital over spdif (or AES) or streaming, and either digital or analog for the front two channels after Dirac processing and volume control from the nanoAVR DL from the theatre system.

In the first case I want Dirac Live, volume control, and bass backend routing to stereo subs; and in the latter I want fixed volume at 100%, no Dirac Live processing, and no bass backend routing (though I could live with it). Each such preset should have an associated input, and it should be possible to "lock" input and volume control (to a fixed level) in a preset so it can't be altered in that preset.

In a scenario like this, switching from one preset to another without first switching inputs and setting volume could be disastrous when one preset requires volume to be fixed at 0 db (or some level) and the other would never be set that high. So: preferred setting for input and volume in each preset and whether those selections are "locked" or not for each preset (locked or not as a group would probably be fine).

Does this seem unreasonable?

It would let people upgrade and integrate a 7.1 Dirac Live theatre system to include high res (streaming) audio with ease just by adding an SHD.

It does not strike me as difficult. I would be willing to help make this happen and would probably buy an SHD if it were done (please tell me it is rackmountable).

I run a 2.2 system and would definitely make use of this sort of feature in a slightly different way.

I'm currently setting the following manually:

Preset 1 - SPDIF input - Music with flat target curve in Dirac
Preset 2 - SPDIF input - Music with added bass target curve in Dirac
Preset 3 - RCA input - TV/HTPC/movies with added bass to suit LFE in Dirac

The RCA input is from an AV receiver's front pre-outs but in my case the AV receiver's volume stays fixed. Volume adjustment is always on the SHD. AV receiver used to switch the audio source between HDMI from HTPC and TV (via ARC/optical).

Yup: preferred, possibly locked inputs per preset.

In my case I want to lock volume on one preset since 7.1 volume control is done elsewhere that cover the two channels just switched through.
