Thanks Keith and Peter,
This sounds very interesting. I have been thinking along similar lines to this project already, as several UK B&O stores have asked me if a replacement for Beolink Passive could be developed which is smaller (to fit inside passive speakers or in a ceiling void), more flexible (ie. simple and easy to configure) and cost-effective (to appeal to wide range of new and existing customers).
One suggestion at this stage is that the board itself could be modular, ie. the most basic format could have analogue audio inputs and digital power amplification only, with the digital processing kept as a separate plug-in module. This would keep costs down and could provide a better fit to the three example customers in the presentation.
Situations that I regularly see where this project could be of benefit include the following:-
1) Beovision TV to be used with the customer's existing high-end hifi loudspeakers, so a good quality power amplifier is required,
2) B&O products are installed in a new build home that has passive ceiling speakers fitted in every room,
3) A long-term B&O customer wishes to upgrade their passive Beovox speakers for use with a newer TV or audio system.
On a basic level, 3.5mm minijack, RCA/phono and RJ45 audio input connections would greatly ease the process of integrating this project with the widest range of B&O, hifi and portable audio devices.
I will be interested to see how this idea develops!
Kind regards, Steve.
