What it is<\/h2>\n\n\n\n

KnobSwitch is a minimal entertainment center controller. One big-ass knob for volume control and one selector switch for input source.<\/p>\n\n\n\n

What it does<\/h2>\n\n\n\n

Gives you instant, simple selection of your input source and volume control. Communicates to your equipment via BLE and RS-232.<\/p>\n\n\n\n

I have a Marantz SR8500<\/del> SR5010 with a serial port. Yes, you could<\/em> use IR but I want this thing to be reliable, i.e. closing the control loop with feedback from the equipment.<\/p>\n\n\n\n

The Marantz receiver is lovely but scrolling through all the inputs using the big knob on the front is maddening and slow. Using the remote is even more maddening<\/em> because it has a thousand tiny buttons<\/del> I dont’ have one anymore, and I recently installed the receiver into a rack so it’s no longer in the line of sight.<\/p>\n\n\n\n

I’d like to have one place to control both the audio volume and the overall input source. This requires fusion of audio and video source switching.<\/p>\n\n\n\n
