## Questions & Answers

**Q: Does sub out have low pass filter built in?**
A: TPA3116D2. The specs for this board are defined by the IC.

**Q: What do you mean by "use high performance switch power dont use transformer"?**
A: A switching power supply uses electronics to transform AC current into DC current of the correct voltage for the application, a transformer is simpler but less efficient. Laptop chargers are an example of switching power supply, while your routers power adapter is probably a transformer type charger.

**Q: Fbhdzvv tpa3116d2 amplifier board can this be used for a guitar amp?**
A: A signals a singnal..adapt male bannana guitar to 3.5 for board

**Q: With no voltage regulation onboard, what is the likelihood that this 12-24vdc unit will work with a 25vdc battery pack?**
A: Id try for the price
But no certainty

## Customer Reviews

### ⭐⭐⭐⭐⭐ Reasonably priced.
*by K***. on March 11, 2025*

The item matches the description perfectly. It is built to be heavy-duty, ensuring durability and strength, making it ideal for demanding tasks. Additionally, the price is quite reasonable considering the quality and performance it offers. I wholeheartedly recommend this product to anyone in search of a reliable and sturdy option.

### ⭐⭐⭐⭐ For $9, it works for most users. What else do you need to know?
*by P***R on October 9, 2020*

Obviously, for $9, what do you have to lose? If it powers on, that's a plus... add a star. If it makes a sound, that's a plus... add a star. If it provides 2.1 stereo sound with subwoofer, LOUD and undistorted, that's a plus... add a star. We're already up to 4 stars, so if it has quality sound too, then it's a 5 star product... for just $9.Questions: where are the highly vaunted TI TPA3116D2 amplifier chips? Under the heat sink, I hope, because the only visible amplifier chips are two TI NE5532P 8-pin chips. Other components are 11 tiny capacitors behind the control knobs, two small caps (100mmf at 35v) and two large caps (2200mmf at 35v). Each speaker output is flanked by a pair of regulator (?) coils.Line level input is through a 1/8" stereo jack or a 3-pin audio jack (probably recycled from a discarded sound card). Power from a switched power supply, 12 to 24 vdc, up to 5a, enters through a 5.5/2.1 mm jack or a 2-wire jack.Don't worry about buying a plastic case for this $9 amp, unless you have inquisitive kids or a cat. They won't get a fatal shock from 24 vdc, but touching any powered-up amplifier doesn't do it any good. Four stand-off screws keep the circuit board from shorting out through the exposed underside.Any $9 amplifier is going to have minimal quality control, so give yourself some margin time to reorder before setup for your stadium concert gig. You might even want to order a backup $9 amplifier just in case, because the specs don't show any MTBF statistic.

### ⭐⭐⭐⭐⭐ Probably the best on Amazon
*by L***H on February 18, 2021*

It says 100 watts, and it's true. I actually was able to pull 150 watts through the bass channel and 100 watts from the left and right so you get more than what is advertised. The independent channel controls are nice too, If you are facing towards the face of the knobs the farthest left knob is the Left and Right channel volume, the middle knob is the Bass channel volume, and the farthest right knob is the Master volume. As for the terminals, if you are looking at the amp top down with the knobs facing towards your chest, the farthest left terminal is the left channel, the middle terminal is the right channel, and the farthest right terminal is the bass channel. The screw in wires are great, and the aux input is a life saver, it is a hundred times better than the 3 pin input, those things drive me wild. I'm running mine on a 7.5v power supply. It says you can use 12 volts, and yes, you can, but you have to be much more careful about the amperage of the power supply if you use 12 volts, as it will get hotter faster. So you could buy a lepai amp for 40 dollars and get 25 watts on 2 channels, or you could spend 1/4 the price and get 4x the power. Get this amp.
