Is the BR4 also suitable for older devices like the BP25 pre amp?
What I could find:
The BR-4 is designed to control virtually all modern Bryston electronics and to be intuitive to use while maintaining Bryston’s legendary durability.
• Works with the following models:
SP2, BP6, BP16, BP17, BP-173, BP-18, BP26 Preamps
B60R, B100, B135 SST2 and B-1353 Integrated Amplifiers
BCD1, BCD-3, BDP1,BDP1-USB, BDP2 Sources BDA1, BDA2, BDA3, and BDA-3.14 D/A Converters
• Easy to feel buttons
But also
711 SP1.7/SP2
712 B100/B135/BP16/BP17
715 BCD1, BCD3
716 BDA1, BDA2
717 BDA3, uses device ID 6
719 BDP3, uses device ID 9
721 BP25/BP26
722 B60/BP6
751 Preamp volume control is used in either D/A or Preamp mode.
Why is the BP25 not mentioned in the 'works with the following list'?
And what does not work with the BP25 ('phase' or 'mute' for instance)??
And what about source select?
