  • 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 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.
  • Excellent product. Nothing else

    A very small size, but very powerful for car audio and hifi audio. For the noise, doesn't exist. Excellent relationship price/quality.It consumes only 12v, which can obtain from a car battery, or a 12v adapter. Along with the connector, there will not be the problem of uniting cables.
    Caution to put some sounds with very power, can saturate.
    Powerful and small, Very reccomended.
  • Great Item!

    It's cheap, light and very effective concerning the over drive distortion effect. It comes with a battery in it, witch is very good. The clip is the best part: it was really made to carry it with you wherever you go.
    It's very useful, especially for people who has to practice and don't have enough money to buy a normal size amplifier or don't want to bother the neighbours. Also, you can use it as a very cool piece of decoration.
    It's cheap, cute and very useful for guitar students.
  • 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.
