    I put this little one to the test with a 28-0-28 V AC toroidal power supply. It performed outstanding and in line with the specifications. Measured with a scope and a Voltcraft voltmeter (to be sure) at 40 Hz and 1000 Hz sinus. 28 Volt on a 4 Ohm load (bigfoot speaker box) with appr. 1 % distortion = 196 RMS Watt, (up to 32 V with appr. 10 % distortion = 256 W). Couldn't get the temperature of the heat-sink higher than 35 degrees Celsius during the tests.

    Being Class D amplifier this mini giant amplifier module is highly efficient. The stock heat sing is good enough and temperature is fairly under control. The output is good enough to power 6 to 8 inch bookshelf speakers. I was surprised to hear the quality from this Little chip.

    The only problem is an absolutely terrible volume control that adds extreme distortion at low volume, best to leave it at max and control volume some other way. Everything else very good, sounds great, very powerful, AC or DC power input makes finding a power supply easier. PCB and components are very good quality for the price, the only thing different to photo is power supply caps, which are replaced by some cheap chinese brand but the quality looks fine so shouldnt matter.

    the product arrived on time. at the operating probes it is found that the left channel does not work. I can see post-production welding traces on the potentiometer

    It is as yet to be tested, probably to-day ! I will be using a PWM power supply to power it up with +/- 35 Volts. Hope to get this baby into a cool box. The box is all that is missing, Now that is what is missing with Banggood ! We want BOXES !!
