Finished a DIY project over Xmas.
It's a 6 channel TPA3255 in PBTL. It was designed as a low cost built and the financial limit was 600 bucks, as this is the amount I gained by selling some electronic stuff.
Not much to say about it, just modded the boards a bit and put them with a 48V 20 A SMPS into a acceptable case.
Finished weight is about 11.3 kg, StandBy consumption <0.5W. Everything works flawless. In simple stereo mode @ 6 ohm fullrange speakers there's already enough power for my needs, not to mention 3 way active config with double bass @3 ohm when PBTL delievers plenty current.
Included:
auto start module (-58 dB signal on)
FI protect
programmable timer (anti popp)
main soft start
5V sec. SMPS
primary EMI filtering for each SMPS
Neutrik connectors
silent fans (optional for hot summer days)
Some pics of the built, not only for the Ego but for inspiration, as I got inspired by some forum postings too.
