  • amazongly powerful and good sound quality

    posted by adjevanhethof

    - very low energy consumption on idle- good build quality: PCB is properly assembled with goor quality components- good sound quality, no quiescent noise, distortion or other audible artefacts. Frequency response is good also, deep powerfull bass and clear high.- powerfull sound, already starting at supply voltage levels from 8V.
    this is a great little amp that can be directly hooked up to an Ipod, mobile phone or media player. The potmeter has a smooth control and adapts for the typical output levels of these devicesI have combined the amplifier with a Bluetooth stereo receiver module and a Li-Ion battery pack, all available from DX, powering a set of old car speakers. This setup makes a great wireless boombox with lots of power and great sound quality, comparable with the ones that cost hundreds of dollars.
    great value for money and quality component.
  • Good if you know how to use it.

    Very small footprint for mounting in a project. Easy to wire, and works great off an Arduino power pin. When wired to a 4ohm speaker, amplifies the signal nice and loud. Great price, other places sell this unit for $15 or more.
    a small wiring diagram would be useful. There are some pictures online of how it can be wired.
    Good for making your audio loud, but requires an external volume control.
  • 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
  • Amazing for the price and the size!!

    It is Small, powerfull, with clear sound. allows to control bass and tremble and you can plug a USB reader.in the images it would seem bigger than it is. so it's smaller, more or less the size of half a 3.5" Hard Disc.
    Very useful if you have a pair of old speakers (not very powerful though) and your HI-Fi stoped working and you want to use them without needing to buy a big amplifier or a new hi-fi equipment.
    Amazing sound for this price, and good quality
  • Good amp

    Very powerful for its sizeQuality of sound is amazingTA2014 chip - look for one, really high sound qualityGood volume knobPower switchNicely backlit, not annoyingGood screw-on contacts on the back
    comes with the power adapter. red backlight is very subtle around the knob
    Very satisfied, does the job well. Drives speakers several times more than itself - definitely get one if you're looking for not so powerful amp with decent sound quality
