Douk AudioM1 PRO 320W Bluetooth Power Amplifier, 2 Channel Audio Amp, Wireless Receiver, for Home Stereo Speakers/Active Subwoofer, with Treble & Bass Control/U-Disk Music Player

To being, this little amp is just what I needed for my application. I'm powering two Definitive Technology AW6500 outdoor speakers with it.Pros:Size - This amp is small in terms of amplifiers. It's Class D, so small form factor is the name of the game.Power - The power it puts out is consistent. I have no issues powering my 200w speakers as this amp provides 160 watts per channel.Features - The bass and treble control was a huge selling factor for me. Having the ability to adjust the tone sets this amp apart from others. The knobs have a metalized texture that allows for easy adjustments, even with wet or sweaty fingers. The inputs and source options are a big plus as well.Speaker connectors - The connectors on the rear of the amp that accept speaker wire are decent quality. The screw posts that retain the speaker wire are made of plastic, which seems pretty standard for these amps. I'd suggest using the banana plugs to maintain a more reliable connection, especially if you move the amp from time to time.Cons:Bluetooth - While Bluetooth connectivity was the primary method of connectivity I had in mind when deciding to purchase this amp, the range of the Bluetooth is poor. Most Bluetooth is reliable within 30-33 feet. When having my phone in my pocket and walking 15-20 feet away from this amp, it can cut in and out, and it's solely a BT connectivity issue. With Bluetooth 5.0 technology, I'm not sure an external antenna is necessary, but it's worth noting that this amp does not include an external antenna.Overall, I'd recommend this amp to anyone looking to power accessory speakers like bookshelf speakers or outdoor speakers. I have not used it in a home theater setting, but I imagine if your setup is compatible with the ports on this amp, it would work well. The Bluetooth connectivity issue I mentioned is manageable (which is why this amp is still getting a 5-star rating) if you leave your Bluetooth connected device nearby, but it's definitely something to be aware of if you plan on being at the outer reaches of the Bluetooth connectivity range.

I bought this to connect to outdoor patio speakers and it works great. It has plenty of power, I run the volume at 50% max, and sounds great paired with my 10" sub. The bluetooth functionality works flawlessly. It connects to my phone instantaneously when switched on. It also has the option to play from RCA and usb sources which is convenient for switching between TV audio and music via bluetooth. I have the unit mounted on the arm of a TV wall mount hidden from view for a very clean appearance. It has done great all summer outside in hot and humid Florida. Recommended.

Excellent sound quality and works well with an active (powered) sub. The Bluetooth 5.0 quality is excellent, even with no antenna (which makes it look slightly sleeker than those with - personally I don’t care). The range from this Bluetooth 5.0 unit without an antennae is about the same as other brands that have antennae’s and Bluetooth 4.2. That’s nice but from what I’ve read about Bluetooth 5.0 range - if they had an antennae on this the range theoretically would have been phenomenal.Was getting the odd pop and click once every couple of hours - until I got a one piece 3.5mm to 2 x RCA (don’t use adapters, use a one piece).Returned my Foster Audio (without sub out) which was also great quality. Both sounded and looked much the same. But I had a spare powered subwoofer sitting around in wanted to use, which adds significantly to the sound quality for me.Lastly, also like the control switch selector from BT, RCA and Off. Other units can be auto switching, which can be beyond annoying. Whichever one you end up buying, look for a switch to control that functionality.

I have owned several of these little digital chip amps from Fosi, Douk, Nobsound, etc-etc. This one is my favorite. These are FAR from their rated power of "160 watts x 2". Not sure why companies inflate numbers. Williston Audio Labs on YouTube uses an audio amplifier dyno to measure power amplifiers. I find his results dead on accurate for us "old timers" more familiar with 1970/80's amplifier ratings. His results without getting too technical:85 watts per channel at 4 ohms certified (1% THD)He was running the stock 32v AC/DC adapter. These amps are not rated for 2 ohm loads, but he tested them anyways:135 watts per channel dynamic RMS at 2 ohms "burst"Impressive! Again, this is with the stock adapter.These chipsets can run up to 36v...so, if you buy a 36v (10 amp) adapter, I am sure you might squeeze more watts out of this unit.SOUND QUALITY- these are the warmest sounding little amps I have ever used. Dead silent, distortion free (until you clip it)FEATURES- sub out and selectable inputs with a switch is excellent.- USB for source music -- old school cool!- Bluetooth is top notch - no issues connecting and rangeBOTTOM LINE- It is not a "160w x 2" amplifier but, powerful enough for 99.9% of buyers. With a dedicated SUB-OUT RCA jack it is ready to go. Buy it. If you listen to your music really really l loud and need a little more power, get a 36v (10-amp) AC/DC adapter. For most, it is not really needed. This Douk M1 PRO is my favorite little digital chip amp with great sound, features, and power
