New project : R-2R Attenuator With Remote Control V2

[rodelius]

Sorry to resurrect such an old post ...

In 2009 I bought one of the R2R V2 volume control kits mentioned in this thread.

At the time, I was about to move into a new house and didn't have time to put the kit together.
During the move the kit was lost and I did not find it until a few days ago when I was about to throw away a box of old audio magazines!!! The original box with the kit was inside the magazine box.

I don't need a volume control anymore these days, but I'd like to put the kit together and wonder if any of you keep a copy of the pdf manual that BPP, the designer, sent us.

I connected the kit and everything seems to work fine, but I can't get the remote control to work and, frankly, I don't remember if in addition to connecting the IR receiver, the remote had to be configured in some special way.

Thanks in advance.
Rod

Wow, thanks!!!
That was the missing piece of info I needed!!!
I did not test it with a signal yet, but everything seems to work as expected.

Best,
Rod

Make sure you position it with a good few inches of space to the toriodal. It works realyl well, but was a bit sensitive to picking up hum from the toroid. I moves it away, maybe 4 inches, and its now totally silent.
