I'm currently working on a whole home or multi zone amp for my house. I thought I'd challenge myself with this project instead of purchasing one also I think I can do it cheaper, but its not about cost but more the personal reward.
I thought for a time saver I was going to use some ebay LM3886 kits, did some reading on here and other forums and got mixed reviews, I figured it just background music not a hifi system so it doesn't have to be the best quality just descent.
First question I'm going to have 4 zones or 8 channels should I build it as 4 stereo amps with separate PS and transformer or 1 large PS and one large transformer.
Second question splitting the audio signal, all zones will be feed from the same source volume will be controlled with a PGA2311 using a app on my android phone or tablet to a Arduino, does the signal need anything to split it, I found some people using a TL084 op-amp to split it or should I be OK with out?
Thanks in advance
