Sure electronics 4*100 watt @ 4ohm, TK2050 D-class Audio Amplifier Board

aquapiranha · 28th August 2009, 08:01 PM

Hi all. I am thinking of using this amplifier to power my upcoming OB's (2 x alpha, B200 per side). I have a couple of noob questions though...

Will the sound quality of this approach that of the trends TA 10/1 that I used to love?

What sort of PSU would you recommend, bearing in mind that all 4 channels will be driven from a Rane crossover? and where might I obtain one? I would prefer a pre-built unit so that I just need to put it all in a case.

Many, many thanks Steve

Hello, good project !

I use this amp board with a S350 Meanwell smps supply.

Meanwell's are the way to go but I have mine running on 2 identical 300watt computer psu's wired in series for 24v. Sounds great to me

Hiya, I've got the 2*100W board and was wondering if you can change the speaker impedance from 4 Ohm to say 6 or 8 Ohm?

Are there any mods for this type of thing?
