  • nice amplifier!

    posted by rebel4life

    -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.

    You will need a strong and clear INPUT signal, so connecting a smart phone to 100W speakers will give you distortion when turning up the volume even a bit : )It is an amp after all, so it will not make any sound better or worse. It amplifies and it does this job very well. I am impressed with what you get for this price
    Best for amplifying voice
    You won't get any better for this price and size.price/quality ratio is beyond expectations
