  • nice bang for the buck

    complete solution. from rectifyler, bulk caps and pre amps.preamp has many adjustments (subw cutoff freq, subw vol, tre, bass...)
    this should be produced in 3 different boards. 1 for sub. 1 for each channel and preamp + rectifier stage. much better for your DIY hobby.
    would most definately recommend.
  • a basic powered mp3 player

    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.
  • Great small powerfull amp

    posted by JanJacobsen

    Damd nice very small and powerfull amplifire.Small of size, but big in power.
    The amplifire board is very easy to set up.Needs only 2 x 12-20 volt ac, so its very very easy to setup, and install.I use it with a 2 x 18 volt trafo, and that gives a bright and clear sound.
    Working on a ballanced input module, so I can use the power amplifire as mono modules at 150 watt.To be used as active speakers.Best of all, is the very low heat from this amp, so no extra cooling is needed.And that is why, this module is ideal for use as internal power amp in a speaker.
