# About
|
|
|
|
|
|
|
|
|
|
This project ultimately seeks to be a "logic control" modification for a
|
|
|
|
|
Denon PMA-770; allowing one to do things like change inputs, volume,
|
|
|
|
|
balance, and tone using a remote control.
|
|
|
|
|
|
|
|
|
|
But that's a long ways down the road; so right now it's goal is to drive
|
|
|
|
|
relays and a display to replace the source input switches and input
|
|
|
|
|
display. I am designing it around the aforementioned Denon; but it can
|
|
|
|
|
obviously work for other units with some modification.

output.
