  • Nice little amp

    Involvement Level: Expert (understands the inner workings)

    Pros: - This little amplifier puts out some nice sound.
    - The small package is great for confining spaces.
    - Stays cool, no heatsink needed.
    - Nice low price.

    Cons: - None, as long as 3 watts is all you need.

    Other: I am building a sound board for a haunted house with six MP3 players and these amplifiers. Great DIY project amplifier, I would recommend this for low volume applications. For the price it can't be beat!

    Involvement Level: Expert (understands the inner workings)

    Pros: -the device is small
    -the amplifier is very cheap
    -the device is easy to use

    Cons: -strong noise at 1W output power
    -a lot of harmonics
    -screw terminal is made out of cheap material, it should be replaced by a dc power connector

    Other: If you need a small amplifier for low volume application, buy this, if you need more power, you should buy something like SKU 44123.

    Pros: Very powerful, it's a 3Wx2 amplifier, but i connect it on my computer and the sound that i almost couldn't hear beafore, now I can hear it without problem with the volume level in 10%

    Cons: nothing

    Other: I don't know much about eletricity, so I've bought this one just to see if i could make it work and bought the SKU.44125 that is more powerful and it works.

  • This is a really nice board

    posted by JuiceNL on 04:12:43 G3T 23/03/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: This is a really nice board to make a diy USB powered speaker driver. Powered from USB it probably doesn't use the full volume, as USB ports typically deliver between 100mA and 500mA, which is less than needed for max output. However, when using speakers that aren't really inefficient decent audio levels can be achieved. Since I love diy projects like these, I really like this board.

    Cons: The capacitor could be a little bigger, say 2000uF or more. But that's easy to do yourself if you know how to solder electronics.

    Other: For thuis price, it's awesome.
