    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.
  • simple but good sound quality

    - works from 7V - 12V DC- starts with the last played song- good sound with high quality speakers- reads many different USB-sticks- combined on-off/volume switch/poti - line-in connector on board
    Nice to combine with bluetooth-audio module connected to the line-in.I made a wodden case with Visatone speakers and the sound is really awesome!
    It's really worth the money, anyway you need additional good speakers, a power supply and a heat sink.

    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 !
    If you need a tiny high performance amp with mini subwoofer, look no further .
    Great product, very pleased to acquire.
  • Excellent, small and powerful amplifier

    Stereo single-ended configurationPo output power RL = 3 ?; THD = 10 %; VP = ±27 V - 110 W; RL = 4 ?; THD = 10 %; VP = ±27 V - 86 WMono bridge-tied load configurationPo output power RL = 6 ?; THD = 10 %; VP = ±27 V - 210 - W
    The output filter values in Stereo single ended mode should be:RL L C2 ? 10 mH 1 mF4 ? 22 mH 680 nF6 ? 33 mH 470 nF8 ? 47 mH 330 nF
    Perfect small amplifier with a reasonable price
