Review: Good little unit for the price. - It works good. Connects easily to my Bluetooth devices. Great price only thing I missed out on is radio. Using it to power some exciters and volume wise, it's loud enough for my purposes.
Review: Nice compact amp - This amplifier was exactly what I needed for my pool patio. It is compact and has 4 channels that drives four speakers in the pool and covered patio area of my back yard. I can operate the speakers in the pool area or patio area with two control knobs that gives us the sound we want in the areas we are in. The Bluetooth option allows us to run Pandora with ease and the remote comes in handy. I highly recommend this amplifier.

## Features

- 【RMS 4x40W + Active Subwoofer ONLY】-- It offers you the peak power output of 800W in total which lets you drive 2 pairs of high capacity speakers (Recommend to connect speakers with rated power less than or equal to 40W) and an ACTIVE Subwoofer. (For this S-299 amplifier subwoofer output, you have to connect with ACTIVE Subwoofer. WARNING: A PASSIVE Subwoofer is NOT ACCEPTABLE for this amplifier.)
- 【Hi-Fi Sound BUT NOT STEREO】-- It has a high capacity transformer that gives you clear sound without any distortion. It has a harmonic distortion less than or equal to 0.04% this helps you listen crystal clear and sharp music. (NOT surround stereo sound, perfect for listening to music. Not recommended for stereo gaming.)
- 【Multiple Connectivity】-- Latest Bluetooth 5.0 version that gives you a large operating range of 30ft. You can connect it with your music streaming devices like pc/mobile/laptop either with Bluetooth connection, 3.5mm AUX Cable or Headphone Jack. It also supports USB Port, SD/TF Card port.

For example, when using it in your back yard, 2 speakers around your pool area and 2 around the yard and outdoor bar area. You can have each zone at a different level. Louder at the pool where kids are playing and softer at the bar so people can talk.

## Questions & Answers

**Q: Hello. i just unpacked my unit, and when i plug it in, the led display does not come on, how do i get it to activate? is my unit broken?**
A: I believe your unit may be broken.

**Q: Speakers a and c work but b and d do not.  not even the same channel, any ideas ??**
A: Kenneth's answer isn't correct.   The subwoofer connects through the RCA port on the lower right.  I'm not sure why only half of your speakers are working.

**Q: Is this unit a blue-tooth receiver or a blue-tooth transmitter?**
A: think of it as an audio receiver through a Bluetooth or aux connection - your phone would connect to it over Bluetooth (or a stereo 3.5mm cable if your phone has a headphone jack) and send Spotify or other music to this device, which would send the audio out through speaker wires.

**Q: What is the max of watts**
A: I'm not sure of the max watts, but it gets really loud even at 15.  I have to constantly yell down to my son to "Turn It Down!"

### ⭐⭐⭐⭐ I'll never curse the darkness again!
*by O***I on June 1, 2025*

Just hooked it up to my TV audio out, powering two speakers and the sub woofer and it works fine, good clear sound, nice and quiet, no hiss or noise. It doesn't have a mute setting on the remote, but just power it off and it will do the trick. Speaking about powering off, when you do, the display turns off, however, the bright blue LED light at the knobs stays on! It takes a good power outage to realize how much light there is in your home from all the LED's in your stuff. I might open the case and disconnect the lights at the knobs, or I might just bask in the warm glow of the parade of LED's in the room!
