  • Very powerful for it's size.

    posted by stamatis75

    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.
  • 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 :)
  • nice amplifier!

    -the device is small
    -the amplifier is very cheap
    -the device is easy to use
    A low pass should be placed at the output, this amplifier creates a lot of interfering signal, you should also use it in a case made out of metal and the wire to the loudspeaker should be as short as possible.
    Please replace the screw terminal with a dc power connector.
    A case for this amplifier would be a nice "addon".
    If you need a small amplifier for low volume application, buy this, if you need more power, you should buy something like SKU 44123.
  • Nice little unit.

    I get tired of having to use my phones touchscreen EQ to adjust the audio before being sent to my amplifier. This does the trick well! Pots rotate smoothly, no crackling, or other noise. Unit looks nice and had no defects.
    Mounted it in a leftover clear plastic helicopter servo box. It worked out nicely.
    Sometimes "old school" is better than new technology.
  • 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.
