Ah, the "requirements definition phase" of a project! Leading to system functional design...I was a systems engineer for 35 years. 🙂
Taking the below:
- PowerLink socket old DIN style or RJ45? - I'd say RJ45, probably cheaper, smaller to make a better/easier form factor, and since B&O has embraced these R45 to PL converters are easy to find.
- TOSLINK output for newer BeoLabs? - If you want it to appeal to those of us who aren't Beoluddites, yes.
- 2 or 2+2 channels? - 2 channels is fine for me.
- PL data signal for Penta and BL5? - I don't care, some would, but the number of such speakers is declining, so I'd say no unless it's very easy and cheap.
- AUX input? Digital or analog? - Definitely yes, for me analog is fine (two would even be nice), I'd guess digital would be of interest to many, so I'd say both.
- Connector for the silver IR eye? Normal 38kHz IR? - Might be useful, but I don't know. I only have one eye up but if I put the thing in a cabinet some kind of eye would be nice, then again people can buy IR blasters, having it respond to both B&O remotes and "normal" IR freq would be a plus.
- 2-way IR for BL7000 / BL5000? - Small market, wouldn't help me.
- Integrated amplifier for BeoVox? - Interesting idea, but personally I'd say no, but analog preamp outs via the RJ45/PL could easily be connected to an outboard amp, a 12 volt trigger out would help with that to turn on the outboard amps.
- Maybe even WISA using one of those Summit modules? - WISA would help sell it to frustrated Moment buyers.
- Display? No cogent thoughts on that, however, if it had an app to run it, on iOS and Android, that showed what it was playing that would be the bomb. I think the future is app based and since it's a microprocessor...
Hope this helps. This is a very promising project, maybe we can get the ghost of David Lewis to contribute...
