It worked nicely to boost the audio signal so the sub now works as it should. We use our soundbar for movies, but often just for streaming music too (Bluetooth, Pandora, etc). Unfortunately, the soundbar’s sub output was super weak. Before, my soundbar’s sub output signal was so weak, it often wouldn’t even turn the subwoofer on (it’s an auto-on subwoofer that powers on when it senses an audio signal). And when it worked, the sub signal was so weak, it sounded like there was no subwoofer at all, even when the subwoofer’s volume was all the way up. You had to get right next to it to even know it was doing anything. Putting this in line between my soundbar’s RCA output and my subwoofer’s RCA input boosted the signal perfectly so I can now hear the subwoofer nicely. The volume knob on the subwoofer now will go from relatively quiet to full dance party mode. I had no issues with the “hum” that others have mentioned. It’s as quiet as can be, and I don’t even have the optional ground wire hooked up. It does have a ground wire connection on it, so connecting that to the chassis of your stereo, turntable, subwoofer, etc, would likely eliminate much of the hum people have mentioned (I’ve had hum issues on my other stereo and a ground wire connecting all the audio components’ chassis together solved it). I’d definitely recommend this if your system is sending a low level signal to another component that just doesn’t have enough uumph to get the audio levels that it should be getting.

There is a grounding screw on the unit. Just hook the ground wire from turntable to it. Griuning to other devices would be the same **Q: Can it be connected via rca to a mixer to produce sound from a turntable? i have my power speakers connected to the mixer already.** A: Hello, It can be used as a preamplifier to connect a turntable, and the turntable can be connected to the RCA input interface of the product through the RCA interface, and the product can be connected to the active speaker through the RCA interface. **Q: Does it have a volume control?** A: Hello.This product doesn't have a volume control. **Q: Is there an on and off switch to cut the power when not using. It would be good to leave hot 24 hours day.** A: My experience is too leave it on all the time because it often malfunctions when I turn is OF and On again. But I have now given up trying to find a preanp that does not constantly amplifier 'noise' and so I hooked up al my audios/AVs to a switch box then to mt stero - the sound comes from my stereo not my TV. And the only DVD player that works right in a Sony although its controls are reverse of convention. Sorry for the errors - I'm mostly blind. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Helped my subwoofer get enough signal to turn it on. *by I***N on January 9, 2024* I’m using this in line with my soundbar’s sub output (which had a very weak signal).
