  • 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.
  • Very powerful for it's size.

    Small size, can fit nicely in a small project box.Quite powerful, tested it with a 100w roister speaker and run it decently. Voltage used was 18V.
    I used an old bicycle flashlight that run on D batteries as case and fitted connector for power supply from an old broken hp printer, as speaker connectors i drilled and fitted banana jacks to make connected speakers easy. The power adapter i used was from the same hp printer which was at 18v 2.23Aps.
    Very nice product for DIY projects. I would buy again.
  • Superb Micro amplifier

    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 !
    This will be sooo good for Rasberry pi user, how cool would a tiny 5 volt sub+sat system be ?
    If you need a tiny high performance amp with mini subwoofer, look no further :DI love this little amp bored x
  • Good amplifier for all your 2.1 needs

    This is a great low power consumption 3 channel amplifier, it can run from very low voltages with no loss of sound quality, just lower power output, works very well with all the DX buck boost convertors SKU 214310 so you can run it off 12vol well... very low noise, and when paired with good speakers the quality is outstanding !
    I brought this for use on a push bike, the sound pumping off your bike with this module at the heart of it will make all your bike friends jelous, mayvbe with solar and dynamo power you may never need to run out of battries.
    I really like this amp, it does sound very good for the price :)
  • Great for DIY

    -Very useful audio amplifier board for DIY speaker and robot...
    -Excellent sound quality and loud enought.
    -Good build quality.
    -Does what it say.
    I use few of these in my RC cars and robots and its loud enough for most voice and signaling application... but maybe not loud enough for a sound system...
    Buy it if you need to integrate sound in your DIY project.
