Hello,
I am planing to use the SHD Power in the following way:

- On the digital AES/EBU-Stereo-Output my Main Speakers in living room will be connect. These are active speakers and each one will have an Hypex Fusion fa503 module. (Zone 1)
- On the two analog outpus my two passive Stereo-Speakers on the balcony will be connected (Zone 2)

Is there a way to switch between the "zones"?

That means I create a preset for example called "living room" and then signal will be only routed to digital AES/EBU output and analog output will be muted.
Also then the dirac filter for the main speakers will applied.
Then another preset called for example "balcony" will then mute the AES/EBU output and will only output to Analog Powered output of the SHD Power.
Also then a the dirac filter for balcony speaker will applied.
Also I want to control the volume via the app independent which zone is select.

In the manual on site 40 I have seen that there is a matrix router with 4 outputs. The question is what is exatcly output 1-4? 
Are these only the analog outputs (out1/out2 = powered and out3-4=analog rca?) or can I configure the ouputs that for example out1/out2 = analog powered and out3/4 = AES/EBU?

regards

Steffen

no one an idea? In short, the question is, can the digital AES/EBU outputs be used as outputs in the Routing matrix or ar the four outputs of the routing matrix only analog outputs?

The 4 outputs in the routing matrix send the same signal to all analogue and digital hardware outputs all the time. There is no way of turning off certain hardware outputs at all.

The 4 outputs in the matrix are simply the 4 mono output channels. They're output both digitally and analog, via three different outputs actually: 2x (Stereo) spdif, 4x balanced XLR, 4x rca.
Whatever you route to the 4 output channels in software matrix, gets output to all three types of output at the same time.

Also, there's no AES/EBU output, the only digital si single-ended spidf.

I guess you could do something like what you're proposing via presets, but the DIRAC on/off state isn't saved by presets, you'd need to switch that separately.

ok that means, that on SHD Power:

Output1 (in DSP software) = Analog output 1 (powered left) and Digital Output AES1 - left
Output2 (in DSP software) = Analog output 2 (powered right) and Digital Output AES1 - right
Output3 (in DSP software) = Analog chinch out 1 left and Digital Output AES2 - left
Output4 (in DSP software) = Analog chinch out 2 right and Digital Output AES2 - right

is that right?

If yes I can make one preset (for balcony speakers) where input signal getting only routed to output 1 and 2. I will connect my balcony speakers to the two powered outputs.
Second preset will only route to output 3 and 4. I will connect my fa503 to  AES2 and pass thorugh AES signal from first fa503 to second fa503.

If right I can do what I want or I am missing something?
Will volume control also work for digital outputs?

@ steo

Indeed, that's correct. You can use the device this way. No problem to use the preset to change the matrix mixer routing allocation of where Input 1&2 are being routed to. 

Master volume control is for both amplifier AND digital out/analog out. All outputs are linked to the same volume control.

Ah, I misread - I thought this was about the normal non-amplified SHD.

You can also use another preset that has the inputs routed to both 1+2 and 3+4, so you can play both pairs of speakers at the same time. You can even equalize and time-delay individually :)

As for DIRAC - you can indeed have the first preset's room correction setup for living room (balcony's outputs not routed) and the second preset DIRAC set up for balcony (living room outputs not routed). If you want to play all two zones together, you'll have to either pick just one of the DIRAC configs, or create a new one for both (this one you can also effectively "turn off" by hacking the curve with curtains so it doesn't apply any correction).

ok great. No I have some questions regarding software. What would be great if there is one interface where I can control the following things.

1. Control volumio (select song, skip, pause etc...) inlcuding webradio
2. Switch input source from Volumio to other inputs, f. e. USB input (USB)
3. Switch from balcony speaker to living room speakers as described using differnt presets by routing to differnt outputs (Powered output = balcony speaker, AES output = active living room speakers). Is it possible to apply also differnt dirac filters here? That means differnt dirac filter for Preset1 (balcony) and Preset2 (living room)?
4. Control volume (inpdependt from source and output preset)

I have attached a screenshot and I have marked the four features in the screenshot.
If I understand correctly the four features should be controllable all out of this one webinterface. I am right here?
Have anyone of you used the web interface on an android mobile device? Any problems here or is there app available doing all these things?
Also on open topic is, can I apply differnt dirac filters to to my differnt routing presets (see 3.)?

Each of the 4 presets that you can switch between has its own corresponding dirac configuration. That means you can have different dirac configs for all 4 presets, but you can't switch dirac presets independently from the "normal" (routing, delays, eq...) presets. There's then another overall switch for just dirac on/off.

thanks kokoon. That would be ok for me. When I want to have two different dirac-presets for the living room, I can copy preset 1, leave routing the same (to living room speakers) and just change the dirac filter. Is my assuming regarding the web-interface right that I can do all four things? Did anyone use it on android mobile device?

Just checked on my android phone, didn't even know there's also an app for Volumio - only used it in browser before (the app is just the same interface wrapped anyway)
Disclaimer - I don't use volumio at all, I use Roon or Chromecast Audio for streaming. I use a Harmony remote for volume, input, presets and dirac switching.

Answers to your questions:
1: should all work, as that's what's it's meant to do - can't verify though, because I don't have the library set up in Volumio.
2: yes, I can confirm this works - just tested in both browser and android app.
3: I can confirm switching presets works
4: Volume control works through volumio, not sure what you meant by independent from source and output preset - the volume setting isn't saved neither with preset nor input. Whatever volume you set, it will be still the same after switching presets and/or inputs. I guess that's not ideal for your usecase.

In general, I don't really like Volumio UI, I think it's quite clunky.

4. Though each preset has Output Gain controls so it should be able to balance the preset levels such that the common SHD level control is sane for both systems.

Right, didn't think of that, cool. I can't think of any workaround for input-specific gain though.
