Hello,
i am working on a project, and i need help to design it, please!!
The goal is to use the midi protocol to command the volume of Audio links (electric guitar type).
For this, i will certainly use the pga4311 chips…
My question is this one:
The cable plug on my system can reach quite long distances (15m or so). How to know if the pga4311 can drive that, or if i need a driver/buffer chip???
Another question (which in fact is the same i think) : when designing a midi out module, how to compute and design the signal driver placed just before the plug?
thank you for your help,
Alex
