So back in 2016 I build myself an amplifier using an SMPS500R and a pair of L-15D-PRO (IRS2092) boards. While I'm not really dissatisfied with the amp in any way apart from maybe some hiss from the speakers when I have my ears a few decimeters from them, but I am still curious if I could upgrade it bit.
So the weak part is of course the amp boards themselves, so I was wondering what I could use instead of those boards with my SMPS500R? It's a 500w (650w peak) +-45V dual voltage power supply. Not sure exactly what the "dual voltage" actually means since I just bought the stuff after reading about it here and on some other places, but it have three outputs from the power supply to the boards, plus, minus and ground , and with my limited experience I've really never seen this apart from on this boards.
So my question is if it's possible to use this power supply with other boards like some of the modern TPA3255 boards, or am I limited to some obscure dual voltage boards?
Posting some images on my amp for attention as well 😉 Build the case out of an old computer case and some finer wooden boards. Still quite happy with the look and size of it, though the on/off switch in the front doesn't work (it physically doesn't switch as it should, not sure why) and the LED in the front doesn't actually light up (photoshop baby!) even though I've connected it to the aux on the power supply. Ah well, it does the job!
