Be nice, there is a lot of info to digest. I looked in the build guide, would someone point me to a BOM for the IP
, beautiful! Looking at the back I see an AV In, I assume that is a pass thru? What's up with the sub outs?Thanks to all for the nice comments.
@Toys4Boys - yes, AV pass through that includes an LFE instead of just the usual L and R AV bypass that most commercial audio offerings seem to tack on almost as an afterthought. I have long been mystified at the reasoning behind not providing a subwoofer bypass with the L and R - if you have a normal home theatre setup it usually includes a sub. And the sub just might be used with the stereo, so surely a ‘standard’ pass through should cater for the sub?
The extra single-ended output means I don’t need XLR-RCA adapters if I’m not using the IP in a system with a balanced source - like lots blessed by Papa’s generosity and ZM’s Omniness I have built enough components to outfit the odd system. And I had the real estate on the back panel - just.

In my implementation none of the audio signal goes anywhere near the logic - assuming you mean the ESP32 code. The closest the two get is in the Muses and even there the logic is galvanically isolated from the signal. The two don’t even share the same ground.
Not sure exactly what you have in mind but the logic could easily switch a filter PCB in or out the signal path via relays - I’d think that might be reasonably straightforward. That’s how I did the AV bypass and tape monitor - relays switched by a line-level MOSFET turned on/off by a uC pin, pretty straightforward.

Just another tool to try to optimize bass in room, when needed, and conserve amplifier power.
I only saw this now. 😳
Very well done @derekr. I’m truly in awe. You clearly have an exceptional understanding of electronics and microcontrollers. Your Muses attenuator is a masterpiece that the rest of us can only envy.
Congratulations!!!!!!!
I am almost there. Yah, it really takes a long time to build some of this stuff, and then I get stuck on a simple point! I actually had to go to the build guide and find that simple answer. Man, I miss a LOT of info sometimes by me 'DIY' without guidance. Yah, yah, I can do this myself. It just takes 3 times longer that's all.
Anyway, here is the front finished panel, and I might even be done by tonight!
