Nio: ... so that you can listen to the beogram also in the link rooms ...
Possible if BeoMaster 5 is the audio master of your ML system.
Nio: ... and control it with the beo4 reomote?
As the BM5 has only an USB and no DataLink enabled input, you will not be able
to control the turntable by a remote - only manual operation possible!
As already mentioned by Chris, you'll need some parts from Sounds Heavenly:
- an analogue <> digital AUX input converter
- and an adaptor cable to connect the DIN 7pin (BG7000) > 2x RCA/Cinch/Phono (converter)
