DollaTek TPA3255 Digital Amplifier Board High Power Stereo Sound 300wx2 Bridge Mono600W DC18-50V for Subwoofer Speaker

Buono a piena potenza assorbe 10A

Blown away by this little board, used a 12v battery supply (18650 pack direct to P+ P- 3p6s so plenty of current available) plugged that into the "300w" boost converter set to 50v with no current limit. Then in to 2 Celestion Sr1 speakers rated 8 ohm so I was not expecting much considering at 8ohm the chip is rated 150w P/C into 8ohm 1% THD. I was using an iPhone lightning to audio jack with a 3.5mm jack I soldered up with the supplied cable. I can honestly say I maxed out the output on the iphone (spotify audio) and the sound quality was top notch and the volume , well the bass was thumping the high tones were nice and clear and MJ's voice came out like he was there so yea I'm well chuffed. Extreme value for money if you have the right power supply. I have ordered a 48v 10a supply and I'll see then if there is a noise problem as I've had problems with chip amps before that tend to really like a clean supply like battery is best or really well filtered dc supply and not some cheap smps for a tenner. I ran both speakers for a second test as first was just one channel driven and honestly I'm building the loudest bluetooth speaker ever with this amp and about to order a second one before they are gone.

Moc oraz technologia wzmacniacza klasy D. Fajny mały ale wariat. Stosować w dobrze wentylowanej obudowie.

Guter Ton, bisschen sensibel auf Stromquelle, aber das ist zu erwarten.

Excelente
