Warm tips:
- Default comes with ONE 24V/6A power adapter, if you want higher output please prepare another one by yourself.
- Long press play/pause button can switch between 2.1 and 5.1 channel output mode. When switching to 5.1 channel output mode, any input modes can achieve 5. 1 channel output.
- If you want real 5.1 channel output, please use 5.1 channel RCA input. If input 2.0 channel but output 5.1 channel, the stereo signal is processed and simulated to 5.1 channel.
- Transfer 2.0 channel input to 5.1 channel output: with built-in multi-channel signal process chip and circuit, which applies professional algorithms and dynamic separation techniques. Even when input 2.0 channel audio signal, it can also auto allocate and simulate to 5.1 channel and provide excellent smart noise reduction, precise sound positioning and stereo surround sense.
- Multiple audio inputs to work with more devices: with Bluetooth 5.0 / coaxial / optical / U-disk four digital inputs and 2.0CH / 5.1CH RCA inputs, strong compatibility and works perfectly with most home audio devices. U-disk input supports lossless formats such as WAV, APE, FLAC besides MP3, high-quality music can be reproduced and enjoyed.
- Strong power output and multi-channel system building: adopting 3PCS classic TPA3116 chip, responsible for front (50W*2)/ surrounded (50W*2) / center(50W) / subwoofer(50W) outputs; specially add a low frequency output to connect another active subwoofer to easily build 2.0/2.1/2.2/5.1/5.2 channel system and enjoy shocking auditory effects as if you are in a movie theater.
- Independent control knobs and dual power inputs: besides main volume control and treble & bass knobs, also with separate front/ surround/ center/ bass volume control; and specially design two power supply inputs (main/vice) to provide stronger power input to easily drive most home speakers and subwoofers with high power.
- User-friendly design and advanced functions: with detailed function buttons and separate indicators, convenient to use and see the working status in real time; one button to switch 2.1 and 5.1 channel outputs, no need to plug in and out speaker cables repeatedly. Made of aluminium alloy and in compact size, very suitable for those who want to build a mini HIFI 5.1 channel system.

This is a great 4 channel amp. Have installed 2 at my son's who moved in to a house w/ 3 sets of built in stereo speakers and I added my large indoor 12" woofer, mid, tweeter to his living room. So, 8 channels driven. Not using Aux In. Selected Ch3&4 RCA's for Output and fed the second M4. Have 2 at my son in law's house. Same as son's he has 4 Stereo sets that came with the house. There I took his Flat panel TV output and fed the Aux RCA's in for Ch1&2, and selected Ch3&4 RCA's for Output and fed the second M4. Installed 1 in my garage driving indoor and outdoor Bose wall mounts. Bluetooth works great w/ good range. Big bonus for me is the USB. I took my old USB-2 thumb drives and copied genres or "playlists" to a bunch of them. This really is my favorite use. Plug in what I want and crank it up!This is a 4 channel amp, so each speaker has separate volume. Plenty of power. Works for me.Oddities: Looking at the front, the Channels volumes are Ch4, 3, 2, 1 left to right. Being an old time audio guy, Left is Ch1, Right is Ch2 for Stereo. I just wired it so Ch1/3 is my L, Ch2/4 my R. On the Aux input, just hook Source Red to White input, White to Red input. No big deal.Wishlist: USB has Next, Previous & Pause/Play buttons. Would love to see Next & Previous "album" and Shuffle.Update on USB use: It is a bit fussy on the thumb drive you use. Data Travelers work. Patriots USB-2 did not. PNY USB-2 no, USB-3 yes. I just bought a 10 pack of PNY 32GB USB-3.0's that work great. Cheap
Replaced an older Yamaha Receiver 50wx4 with the Douk Audio M4. Mostly because it lacked Bluetooth.I'm blown away by this tiny powerhouse.Paired with 4 Cambridge Audio Cubes and 100 w powered Cambridge Audio powered sub, ( and Fisher 18 channel eq for turntable).I'm speechless how such a small package can pump out so many watts.Saved space and increased output= win-win.
Bought this when I added a pair of bass shakers. The combo of this and the shakers have raised my quality of living.
I purchased this to power my 50w bass shakers. It was very easy to split the subwoofer line to the amp and connect the speaker wires between the amp and shakers.I love that you can control each shaker separately so you can choose which seats to have on. It sends enough power for a great shaking experience.I am not using the Bluetooth options or for any other use.
I use it outside to power 4 speakers. I was impressed by the sound quality, and the bluetooth range. Great product, great value.
