  • Superb Micro amplifier

    posted by skinnybloke

    This is the most aamassing amplifier i have purchased so far from DX !Its not the most powerful, but its so Tiny ! The output you can achive from this far exceeds expectation ! The sound quality is fantastic, low and high level, and a very low noise floor for a digital amp that has no output filter, i will be purchasing more !
    This will be sooo good for Rasberry pi user, how cool would a tiny 5 volt sub+sat system be ?
    If you need a tiny high performance amp with mini subwoofer, look no further :DI love this little amp bored x
  • Nice build quality

    This is a very cheap, but well made headphone amplifier. Works fine and appears to have been contructed with good quality parts. You can use it with a 12v adapter or 12v battery. Now I'm using it with a 3.7v battery with a voltage converter.
    This is an amplifier to be used with headphones, but I'll not use it, unfortunatelly. I have a cmoy amplifier and works bertter.
  • it works

    it does work, there was a guy next to my building(50-60m) on the balcony talking to his phone, i can almost hear every word he says. must have very low background noise to here what people says.
    that dish can be removed to save some space when i need hide it in my bag.
    maybe add a crosshair in the monocular scope is a good idea, so i can aim at the mouth of the subject.
    current dish is too small to reflect human voices to the mic, im thinking of make a larger foldable dish, also increase the length of mic stick to get it to the focal point.
    i have wrote a few pros and so many cons, if i was the designer of this product i'd make it better, theres lots of improvement could be done here.
    anyway, it works,built in amplifier and dish do work better than human ears.

    The module automatically starts playing and repeating all songs. A small delay between songs, no clicks.
    The middle button works as pause, it starts/stops current song. When you hold longer than 1 second it will switch to another mode. Presumable using the line input. The nex/prev buttons now work as volume+/-. This mode is untested. A bit strange because the potmeter regulates the volume too. There is a on/of switch integrated in this potmeter.On the back there is a mute function without a connector. You will need a soldering iron for this.The LED is on when in pause, blinking when playing. When starting up this LED is blinking more quickly for about a second. Then it starts playing. Sound quality untested, with a 5 cm speaker the amp chip gets a bit warmer, I estimate about 30 degrees Celsius.
    a basic powered mp3 player. Works fine.
