  • Amazing punch almost for free!

    What a brilliant little amp!:-Plays music at a high volume, even amplifies an iPod to a pretty high volume.-No distortion that I heard, even at very high volume.-The thing is SMALL! The area of it is just bigger than a normal cigarette lighter.-Develops little or no heat, even if played at high volume for quite some time.-Very convenient board layout.-Gain can be set from lowest to highest by moving one jumper.-On/off pins can easily be connected to a 3-pin switch.-Screw holes in the corners of the pcb, very nice for mounting!
    Get a really small flat screwdriver for this! It is easy to screw the terminals with one, but you'll be swearing without it! May be smart to have some airspace around it if it is mounted in a closed case etc., because it produces a small amount of heat. (You can always touch the chips themselves, so we are not talking of much heat here!)
    Go right ahead and buy it! It is superior to anything I have ever seen for this price! Perfect for DIY, and as a daily amp, really!
  • Great amplifier

    posted by FlavioBayer

    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%
    It also works with my cellphone battery(SKU.23723), but I use an USB port(~5v) as power supply, just get an USB cable from my old printer that don't work, cut it and plug on the device and works perfectly(red=+,black/white=-).
    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.
  • Great FM Transmitter

    posted by engsam

    VMR6512 FM audio transmitter with the power of embedded digital signal processor it offers true broadcasting level performance. Excellent signal level being able to receive strong signal without interference even through two walls and about 10 meters. In the piece I got the mounting plate is well made and good quality.
    Without doubt it is the most powerful FM audio transmitter for home use I tested, excellent for those who have some skill in electronics because this does not ready for use, remembering that will require a power supply of 3.3 volts and a male to male audio cable (SKU: 103641).
    Excellent purchase, worth every penny paid although it may cause interference to radios neighbors.
