If you need good clean audio that uses very little power and space this is the best thing you could get for the money This is a class D amplifier and it generates RF transmission which can be picked up on an old AM tube radio which is not an issue for most people.It did fine to fill your house or shop with warm sound The jumper is for power On/Off, the blank white connector is for Mute when shorted. The little potentiometer is really beefy to the touch;there is a lot of control with that part Parameters: Work: D Class Quiescent current: 20mA Efficiency: 90% Rated output power: 10W +10W (8O) Frequency response: 20Hz to 50KHz Operating voltage: DC 7.5-15V Recommended power supply voltage: 12V, the center PIN of 12VDC is + PCB board size: (40 * 40) mm Power Interface: 5.5 socket Features: -This little amp works well and takes up almost no room. Clear and clean amplification. -With 5 5 DC outlet as power supply interface; high efficiency of 90 percent -With LED power supply indicator, power supply switch and mute switch, easy to operate -The input (3.5mm stereo jack) and the outputs (two pair of screw clamped terminals) Application: You could use it to amp your music for an outdoor party, build a speaker box for your bicycle or just anywhere you need big sound for cheap (bookshelf speakers/electric guitar/garage workshop/ScanDisk MP3 player/home theatre stereos/). Get a good enclosure for your speakers and ENJOY NOTE: 1.It is NOT acceptable to connect the - outputs of the L & R speakers together. 2.If you are expecting an audiophile listening experience, you might want to look at something else, like the McIntosh MC275 Tube Power Amplifier. But if you want to save $5790.00 and have a sweet little audio setup on the cheap-cheap, this is what you need. Package includes: 1x Mini Amplifier Board

Small but Functional
Your browser does not support HTML5 video. I bought this stereo amp a while ago, and finally had a chance to put it to use. Overall it is a very nice unit, and it has clean sound, and I am not having any RF interference issues even though it is packed into a lamp along with a wireless smart home switch, an Alexa Input, two marine speakers, and an LED light bulb and all of their transformers and power connections. It has the ability to use an on/off power switch and a mute button if you have the need which is pretty impressive to have all of those features in such a tiny package. And it is tiny, like the size of a 9 volt battery. Please note that it takes a 12 volt power supply and not the typical 5 volt many small amps take.Overall the sound is clean. I appreciated all of the technical information being in the images on the posting, including -/+ audio out and channel information. The volume control is smooth, and the included knob fits snugly. And as the listing states, this is not a high end audiophile amplifier, but it works great for DIY projects, a replacement amp in a good sized portable radio or amplified speaker system, or in a home made smart home Alexa enabled lamp.

Has to use a certain voltage with the right Adaptatip plug input.
I like you can hook up a 9v power supply with micro speakers hooked into it. A good replacement for a broken blown mini amp. I like the small size of the circuits. Wasn't sure of the speaker wire inputs. A nice kit to tinker around with.

Read the description.
Make sure ya read the description. It says u can add the 10w to the other 10w but that only means you will have two 10w outputs. U can't hook a 20w speaker and bridge the outputs so to me the 10w+10w=20w isn't true. You'll be stuck with two 10w outputs. Not one 20w output. Seeing how I only have a 20w speaker I can't even tell if this works. Tricky wording so pay attention. In the end its my fault for not reading better.
