SPECIFICATIONS
—Work Voltage:DC 9V-24V Above 2A is recommended
—Communication distance:15meter(Without obstacles)
—Match speaker(30W~100W):
— Tip: adequate output power is required when the audio input is sufficient and the power supply voltage/current is sufficient, the relative power will be higher. Different impedance of the speaker will have different output power.In the case of sufficient voltage and current, the larger the impedance of the speaker, the smaller the relative sound power, please pay attention!
Note:
1.The power amplifier board should be as far away as possible from the WIFI signal (router) avoid signal interference.
2.Remove the film from the heat sink and attach the heat sink to the chip.
3.Recommended power supply voltage DC 9~24V.
4.It is recommended to use a power supply of 2A or higher.
5.Please don’t use too long wires to avoid signal interference.
6.It is recommended to use a speaker above 50W to avoid speaker damage.
7>.Please tear off the protective film acrylic board from before use.
8>.Please read use manual and description before use.

Very respectable little amp. Truly no complaints: I’m always satisfied when things do everything they’re supposed to and nothing they don’t need to. The Bluetooth is a good strong connection with surprisingly low latency compared to other more expensive systems, the sound quality is very clear and transparent. Works well with a typical 12V AND 9V power adaptors, and the potentiometer seems decently sturdy for the price. Unless you’re hooking this up to super expensive speakers, this should suit anyone’s needs within the speaker Ohm and input Voltage specs.

Purchased to individually test each speaker in a home multi zone setup. Was pleasantly surprised how good the audio sounded. And the Bluetooth worked flawlessly as well.

This very inexpensive little amp can produce very clean sound, but it is not as polished as the more expensive Class D amplifiers that I have used. With wired connections to a portable MP3 player or computer it produces clean sound, but when wired to either of my cell phones it produces a weak signal with a lot of hiss. This hiss appears to be on the input cable and can be heard on headphones if the signal is split to serve both headphones and this amplifier. The amplifier appears to put a DC bias of a few mV on the input. The Bluetooth connection from the cell phones worked well.Unique to this class D amplifier compared to others is that it draws a little under 10 watts of wall power when idle. This small power in a small device makes the whole assembly warm to the touch. With the loudest signal I could find I could not get the amplifier to draw more than about 25 watts of wall power. While this sounds small it was enough to drive a pair of baby advent 8 inch acoustic suspension speakers loud enough that I had trouble hearing myself shout. Larger speakers would produce more sound with the same amount of power.Overall it is a mixed bag. Because of the issue with the cell phones I am unsure if it will work in all the situations I might intend to use it. But when it works it works well.

I have 3 of these hooked to 3 pairs of Dayton Audio TT-25 and BST-2 shakers, all powered by a Meanwell 360w power supply. Fed by a Startech USB Sound card this setup is super powerful and substantially more cost-effective than off-the-shelf stuff.10/10 as far as I'm concerned. A super simple and easy to use amp for lower powered situations.I will be snagging a couple more to build a 4 ch speaker setup for my sim rig very soon

I bought this just to test out a little 3" Tangbang subwoofer driver. The Onkyo receiver i had couldn't drive the Tangbang and produced tiny sound.When this little driver board arrived, I hooked it to a 19v 4.74A power brick. It drove the subwoofer like crazy with loud sound.Since I still need to work on the speaker box for the Tangbang so i plug this board to my 2 JBL G400 floor standing spakers. And pair the board with my phone via Bluetooth. Wow very nice sound with solid bass even at little at 15% of the volumeThe sounds are nice with either little or big volume. If i turned it up 80% it's too loud for everyone else.The speakers are in basements with no subwoofer but my wife from the floor above says she feels the thumbing from my JBL speakers driven by this board every time I turn the volume above 50%.The analog 3.5mm stereo jack allows me to connect this driver board with my TV audio output. My phone can still play through the same board if I connect it to the Bluetooth. So if Bluetooth is disconnected the sound from the 3.5mm plug will be played. Nice design.Would buy again

This is a fab amp! Sounds great and lots of power. With the dual outdoor speakers, I got a great setup for the deck that only cost $60, including a power supply and speaker wire! Just plugged in an old echo dot and I have music inside and out now!A few notes/tips to consider or help you out:1. There is no Bluetooth pairing button, to change input you have to disconnect the first device from that device.2. I tried several cases but couldn’t find any that it fit in without being way larger. Wish they sold matching cases like the aluminum one in the photos.3. Despite the description, no professional electronics knowledge is needed. It’s seriously just 8 small screws to put it together.But, for the price... it’s amazing. This amp plus an Echo Flex ~ $30, compared to $300 for the Echo speaker amp.My setup:This ampOld 2nd gen Echo Dot12v/5amp DC power supplyDual 100w outdoor speakers

Really nice build quality and pushes a lot of power out of such a small size. The bluetooth works well and connects to my iPhone really quickly. I am powering the amp with a 12v battery power supply for a portable speaker and it gets enough volume through two 3" speakers to really fill a room or use outside. One thing I wish it has was a metal volume control know instead of plastic but that is just an astatic thing. Overall works better than I expected such a small would and would recommend.

Good little bluetooth amp. Decent build quality, and the bluetooth connectivity seems very good.The only problem is the slightly noisy volume pot.

Prodotto molto buono serve solo una piccola manualità nel montaggio. Pilota due monitor AIWA e devo dire che la qualità e la dinamica sono veramente ottime.

Funciona como se espera, estoy usandolo con dos altavoces de 50W @ 6 ohm y es muy buen sonido, sin tenerlas al máximo y en una habitación pequeña, no he probado la entrada de 3.5 pero con la bluetooth es suficiente. no hay distorsión ni ruidos.

Kann meine Uberaschung gar nicht in Worte fassen. Ich haette nicht gedacht, dass so ein kleines Geraet meine gigantischen Boxen ansteuern kann und dabei noch so gut klingt.

Muy buen amp. Tuve que comprar tres previos y no daban el ancho.Buena calidad 👌 mucha potencia.
