Works great! 😎👍Revived some Jenson dual 10inch woofers I''ve had layin around. They still work and they are earth quaking just like i remember. This has a separate channel for 1 sub but I have a dual woofer setup. Wonder if I can run both speakers to the single sub channel 🤔 I don''t wanna bridge it and cause issues.

This thing is built ok. The knobs are ok the connection ports everything is ok. If they used just a little bit more refined parts like the knobs it would be great bc the body looks and feels solid. I think the knobs are metal which is cool but they have an unrefined look and feel. Being a little nitpicky with the knobs. The bottom just has some sticky pads that you can buy anywhere. Like they just slapped them on. Doesn''t look OEM and it doesn''t sit flat. So I replaced them with bigger ones. Same thing it doesn''t sit flat. I guess the bottom panel is a little off like its bent a little so it won''t sit flat. It tilts. So I added a spacer onto the rubber foot and whallah free donuts.

I notice no heat no buzzing but when I used the bluetooth there was some popping clicking sound when I connected and disconnected. 🤔 BT hooks up fast and easy but it would be cool to have a separate on off and pairing button. The BT is constantly on when the unit is powered on. Theres no separate off switch for it.

Overall though quite happy being able to hook up some old school speakers. And it has a separate sub channel with frequency adjustment 😮. If any issues pop I will update but out of box it''s cool and the gang. One thing I suggest is get those banana plugs. 😉

UPDATE: This thing rocks!!! I hooked up some other older speakers to the L & R channels and the dual woofers to the 1 sub channel and it ROCKS. I had no idea that the other speakers were capable of sounding this great. One thing to note I originally thought I needed a bluetooth transmitter to connect this to a device. You don''t. If you are using your phone just look for it. It shows up as a bunch of numbers and letters. It pairs instantly. It also hooks up with Alexa. I believe this was causing some of the pairing issues I had. Now I can connect faster not even having to deal with a BT transmitter. So Happy! No heat no cuts no static nothing but performance like a champ even with 2 woofers hooked up to the 1 sub channel. GREAT AMP!!!

This was the only 2.1 Bluetooth 5 amp I could find when I bought it a few months ago, and it''s been great so far. I love that there are independent sets of controls for treble and bass, including a bass volume knob for the woofer channel. That knob alone has been really handy.

Here''s how I use it:

I have a set of midrange ($300/pair) bookshelf speakers and a woofer from a Samsung all-in-one home theater package. The RCA ins are connected to my TV and I use the Bluetooth to connect to my phone for music (with Amazon Music HD). I occasionally use the RCA inputs to connect to my phone via an RCA to 3.5mm cable when I''m feeling extra audiophile-ish. It''s just nice to have that option. That said, the Bluetooth doesn''t affect the sound quality too much. Also, if that really bothered you, you wouldn''t be looking at a Bluetooth amp.

My favorite feature about this unit is the bass channel and its independent controls. When I''m watching TV, sometimes the bass differs greatly between shows (and especially when I switch to music). It''s hella convenient to be able to change that directly on the amp instead of fiddling with the EQ settings on the phone or TV. I''m really glad I got a 2.1 unit because bookshelf speakers don''t have the big bass I like.

The range on the Bluetooth is pretty okay. I''ve managed to carry the phone to every corner of my (small) house without any problem whatsoever. The build quality is also pretty good. The unit feels solid.

You can only get so much out of the main bass volume knob. But the main volume button also increases bass level, the problem with this is that I''m using this on my desk and it means the main speakers are too loud if the bass is at a decent level. At that point you''d be better off using an amp with an LFE line out for bass and a separate active woofer or amp for your passive sub. For reference, I''m using the RCA line level output from an SMSL headphone DAC.

Sound quality is good and it has plenty of power but the fact that the bass volume isn''t separate from the main volume is a deal breaker for me. I thought I''d get the full bass range from the THREE bass pots but that''s not the case.

Also, I ordered this NS-14G Pro and received the standard version. I''ll be sending the unit back since it doesn''t do what I need, but will be picking up other Nobsound/Douk products to complete my desk setup. I have one of their small 2.0 amps outside for bluetooth by the pool and it works great.

I''m using this for an outdoor stereo system, driving two B&W outdoor speakers and a home-brew subwoofer built in a wine barrel. I''m powering it with a Milwaukee 18V, 5Ah battery pack, so the whole thing is wireless and it will run many many hours on a single charge; I can just bring the whole setup inside when not in use to protect it from the elements. Sound quality is great; Bluetooth range is excellent. I did have to add an external power switch between the battery and the amp, as it does have a few mA parasitic current drain when off. Would highly recommend this amp to anyone.

This is a great amplifier. I’m using it with my Fluance turntable and a pair of Sony SS-CS5 speakers. It’s powerful and runs very clean. Bluetooth devices connect quickly and easily. It’s manufactured well Control knobs are metal and sturdy. You can use banana plugs or crimp and strip the speaker wires yourself. The Bluetooth is always on, and overrides the auxiliary input if your device is connected, so you just have to turn off Bluetooth on your device...not a big deal, but made me think the amp was dead for a minute or two the next day until I remembered that. I have no complaints so far. It definitely has the power to drive the speakers I’m using (they’re 100 watts max power each), and our setup is for an open kitchen, dining room, and living room. The sound fills the space nicely. Don’t hesitate to buy this amp.

I went for the high-end version of this Bluetooth Receiver Amplifier, which I received yesterday with anticipation of a better quality than the Gracedigital that had failed. First of all the power adapter was all scratched (probably already used) and it was 19VDC. The manual says that to get the full power output one requires a 25VDC power adapter. Since I was ordering the Pro version, I expected the 25VDC. To connect a different phone to the Bluetooth amplifier one has to disconnect the power to make it disconnect from the previous phone. If one forgets to turn the volume off, connecting the power again causes a spark at the dc connection. I tried different ways to connect a different phone to no avail, to avoid the sparks. If this is the only way to reset the Bluetooth make sure no volatile gases are around, ie acetone, fuels, alcohol. I did not find the workmanship to be outstanding either, as the terminals for the AUX in were not straight either. I just hope they are soldered inside. This is a safety issue, as no one should experience this defect on normal operation of this device, thus giving it a two is generous enough due to the sparks issue. I am using this amp in the kitchen so when guests come and want to listen to their music, they intuitively disconnect then reconnect the power adapter thus they think they have damaged the Amp. The output power from the amp is disappointingly under power due to the enclosed power supply. I regret purchasing it as I could have gotten a similar amp including remote control at a lower cost. I would not recommend this amp unless there is a different way to reset the Bluetooth to avoid the sparking issue and it comes with the 25Vdc from the get-go. To add insult to injury DHL charged an outrageous fee to handle the imports duties to Canada.

For a regular consumer product its fantastic. the only negative for me is that it will not work wired if anything is connected via Bluetooth. took me a while to figure this out as I thought it was broken and it was just connected to my phones Bluetooth. Gets a little warm if you are pumping the volume but I''m sure its designed to take it.
