Compact size, low profile and low engergy usage. Has got plenty of power for outdoors audio re inforcment. Comes in antistatic foil bag. Comes with a small 3p connector for the audio signal. The condensators where not sitting flush on the pcb's Resoldered them for a more snug fit. Used two of these in an portable diy speaker with a subwoofer and 2 full ... Read more
Low price but good quality, high power amplifier module. I`ve got about 2x40W on 8ohm and 24V power supply. Sound is clear and loud. High efficiency, even with full power have about 40 Celsius degrees Heatsink was askew screwed.
Askew soldered capacitor and speaker connectors.
There is no volume regulation on board. Short conecting wire. Should be a ... Read more
first of all the 50 x 2 is not quite correct atleast not on my board. i only got about 40 watts but could have been my speaker ohms being 16 ohms. other than that great as a subwoofer for small 6 x 9 speaker kit. i did not have dc offset like the other reviewer but could be that i put a 4700 cap vs 2200 cap. could have smaller heatsink as it has never ...

A cheap good quality amplifier, 40W for 1% THD at 4 ohm speakers and 22V power supply.
The input sensitivity is 220 mV because the gain is already set to maximum, very good as a phone docking system. none I am going to install a preamp at input on mine because i will use it for my TV set and it's audio signal is week. See TDA7492 - STMicroelectronics ... Read more
This is a desent class D amplifier.
No background hissing or noise.
Low idle current consumption.
Drives large speakers well (Yamaha NS555) Decoupling cap could be better. Would buy again.
Great for a portable amplifier project
Great for cheap and small amplifier projects. Please make informative reviews, reviews under 500 characters (all fields combined)... Read more
very good product. very loud and clear voice. I advise you to buy.It is a really good , it fits my needs.Just what I needed! it works perfectly audio amplifier board.This is an excellent amplifier. If you need to drive some speakers and don't want to spend a lot of money, this amp will do wonders. the device does not have a problem. but you have to ... Read more
Great sound, does not heat as it's a class-D amp but anyway has a good heat sink. Comes with a signal cable ready to solder to any audio jack and plug it in. Also has the Vcc input and power output ready to insert cables and use. Practical. The package is a plastic bag only and the main capacitor suffers in the trip to your home.
Has a big distorsion ... Read more

Decent sound quality
Build quality is decent, although decoupling cap could be better quality. Current draw at idle 61mA at 17V (w. speakers) DC offset 10mV and 50mV
Decoupling cap could be better. It cant supply 50W into 8 ohms at 26V
Max would be 42W -> RMS V = Peak V * 0.707
RMS V = 26V * 0.707 = 18.38V
V^2 * R = Power -> 18^2... Read more
-Stay lukewarm at low level (<5watt) and around 40°C for 2x15watt approximately.
-No on/off "pop" at all.
-Good sound quality.
-Small and compact board, easy to integrate.
-Great voltage range operation. -Very low humming (at least with a 24v power supply and 90db/w/1m speakers) -Non-negligible DC offset on my board (15mv and 20mv)... Read more
