Interesting. Roughly what I expected to be in there.
The 5-pin chip is an unregulated charge pump used for inverting the + 5V from USB to -5V.
The smaller ones on the other side of the board are indeed some diodes and two resistors. They are used for providing power to the data lines.
would you believe that a BeoLink Passive provides the required MasterLink voltage (as the 1611 does)?
No, unfortunately it can’t.
