Hi all. I am about to embark on a project I have had in mind for a long time. I have just scored a QBL-100 quadraphonic balancer which was made for the QRX5500. This has been covered before here:
https://audiokarma.org/forums/index.php?threads/adding-qbl-100-to-the-qrx9001.399933/#post-5074040
I don't like the idea for pushing audio signals down all that wire and it would be a recipe for dissaster with a child and a cat around so I want to use the remote to send signals to a box which controls potentiometers with servos.
There are cheap chinese 8 channel servo control circuits which comes as a pair: move a pot on the transmitter board and a servo moves on the receiver board.
I will post as the project progresses.
Anyway I opened it up and I am intrigued by the pots. They must be dual pots but I have never seen them like this before. Normally one pot is piggybacked on the other but these are like single pots with two sets of connections. I can't find anything on the net about them. Any ideas?
