Review: Incredible sub amp: great way to turn a passive sub into an active sub! - I'm using this with an S.M.S.L. A300 amp to hook up a passive subwoofer to it's line-level sub output. It is working perfectly for my needs. PLENTY of power output (I've got the volume set to about 1/3). This devices cutoff of 300Hz is plenty compatible with the 100Hz of the A300. I did notice that in theory the sub freq knob should be able to go down to about 1/3 without impact, but I notice the difference in sound far before that, so I assume it's a non-linear scale. Not a big deal, but might be nice if the knob was labeled in some way so you knew what frequency you are dialing in. That being said for the price I cannot complain. Note that if you are using this for a sub amp be sure to select SUB rather than PBTL with the second switch. If you select full range (PBTL) it has a drastic impact on the output. Which is a BIT odd since I'm already sending only 0-100Hz to the unit from the SMSL. NBD since the SUB setting is most correct for my use anyway, but something to be aware of if you hook it up and think it sounds... off. Quiet. Dont take my minor criticisms for anything but that: nitpicks. I love the amp and am completely happy, especially for the low price.
Review: Low noise replacement for a small sub's old amp - I used this to replace a plate amplifier on a powered subwoofer for a pair of monitors. The reason I wanted to replace the existing amp was because it had a lot of white noise whenever it was turned on, which was a problem in the quiet, near-field listening environment I had set up. The old amp also suffered from interference (cell phone buzz buzz buzz sounds). This nobsound amp fixed both of those issues. The white noise is minimal, and it has gain switches (which I set to the minimum value) which reduced it further. Someone in another review mentioned there's a pop when the unit powers off, but that's only true if you cut power to the unit (by turning off a power strip). If you use the on/off switch on the unit there's no pop. The amount of power is more than enough for my needs, which aren't much (it's an 8" subwoofer for near-field listening). The amp stays very cool. The built-in EQ worked fine and I was able to tune it to match my monitors without too much trouble. I wish it had an adjustable phase, but you can always invert the phase by swapping the speaker leads, so no big deal. The RCA input is also a bit of a bummer (my previous sub was balanced XLR) but I haven't noticed any hum or other interference problems, so I guess it doesn't matter. For the price, I couldn't be happier.

## Questions & Answers

**Q: will this power a 50 watt bass shaker?**
A: And by the way..saying "50 watt bass shaker" does not describe or define the bass shaker. 50 watts is merely the recommended peak power. Says NOTHING of how loud it will play, or how good it sounds. Again, power rating DOES NOT DEFINE A PRODUCT.

**Q: Why are there left and right inputs for a mono amp? If you have a mono source, can you plug it into only one input, or do you have to connect to both?**
A: Hello. We have a using guide picture in the listing. You can check that. We have left and right inputs since some customers using stereo signal. If yours are mono, just connect one input.

**Q: When using in sub mode, which rca input to plug in? left or right or both?**
A: Hello. Please see our second main image. The "audio in" rca posts are connected to sound sources. The "spk out" posts are a set of speaker binding posts. When in sub mode, you need to connect your passive subwoofer with bare wire or banana plug. If you still have questions, you can send your device models and images to nobsound@doukaudio.com. We will help you with it.

**Q: When using this with a subwoofer how do I know where to set the frequency cortrol knob?**
A: Like others have said, turn volume up on your main speakers (L/R) to desired listening level then advance frequency crossover knob until you can hear the subwoofer in your favorite music passage, then back the sub down until it is un-noticeable in the passage. Your subwoofer range should take over at the effective L/R low frequency cutoff point...Blend it in seamlessly.

### ⭐⭐⭐⭐⭐ More than enough for home stereo.
*by J***E on December 9, 2024*

Thunder. For 50 bucks I am blown away by this tiny little amp that kicks out big Power. I hooked this up to a rejuvenated old Panasonic ported subwoofer from a mini home theater system from the '90s that was reloaded with a $30 Skar Audio 6.5 inch subwoofer. The adjustment knob for the bass frequency coupled with the volume knob and the subwoofer/full-range switch on this little Nobsound unit can pump out some big bass from a tiny sub. It's powerful enough that I cannot turn it all the way up and at 50% volume it sounds amazing. The signal is coming from the AUX port of my Fouk Audio mini tube amp. This combination along with some tiny Polk Audio bookshelf speakers sounds incredible in a 12x12 bedroom. Absolute High-Fidelity clarity, rich sound, clear vocals, and thundering bass. This is a great mini system that will sound (and feel) awesome for a medium-sized room.
