  • Awesome little amp board for DIY

    posted by cooliosanchez

    Comes with cables!Chip does not heat upSuch a good price!Runs off lithium cells or USB voltages (3.6-5.5V input)Very smallLots of gainSounds good
    Throw a volume pot onto your input lines for volume adjustment (reduction only). Gain seems appropriate for just using mp3 player's built in volume control, though.I really liked that it came with cables, and they were easy to de-solder from the board as well.
    If you need a small amp for little speakers, this one is awesome. A great DIY part!
  • good audio quality

    posted by adjevanhethof

    - audio quality s good, no noise, hum or other artefacts- when running on 3.7v (of a li-ion cell), this unit still functions reliably and produces quite adequate audio levels- input senitivity is such that you can drive it directly from the headphone ouput of an ipod or smartphone- very low qiescent current; will run for a long time on a battery- well built, connection cables were included
    I used this little unit in combination with a bluetooth receiver (also at DX), using the li-ion battery of the bluetooth receiver to power this little amp. totgether with two proper loudspeakers, you get a low-cost wireless boombox with a really good sound quality.
    great component. at this price, there is no point to build it yourself.
  • simple but good sound quality

    posted by CHANDRA66

    - works from 7V - 12V DC- starts with the last played song- good sound with high quality speakers- reads many different USB-sticks- combined on-off/volume switch/poti - line-in connector on board
    Nice to combine with bluetooth-audio module connected to the line-in.I made a wodden case with Visatone speakers and the sound is really awesome!
    It's really worth the money, anyway you need additional good speakers, a power supply and a heat sink.

    This is the most aamassing amplifier i have purchased so far from DX ! Its not the most powerful, but its so Tiny ! The output you can achive from this far exceeds expectation ! The sound quality is fantastic, low and high level, and a very low noise floor for a digital amp that has no output filter, i will be purchasing more !
    If you need a tiny high performance amp with mini subwoofer, look no further .
    Great product, very pleased to acquire.
  • Simples Funcional Bom SOM

    Simples Funcional e Bom Som, poderia ser melhor a qualidade e a potencia pois no anuncio fala em 68 watts rms mais acredito não de isso ou nem a metade disso, alem disso assim que liguei a fonte deu um estouro mais funcionou
