Well it works fine. I have a Vizio soundbar with various inputs. This application is tied to the mini aux jack via RCA connectors. The turntable is a Technics SL Q3 quartz direct drive. He's probably 30 years old. The product arrived on time. Plug in the included power adapter and connect the RCA to the Vizio's mini-input. Launched and lit the ABBA album. You can control the preamp output. This allows you to increase/decrease the volume (gain) of your amplifier. Great deal for most of us. An audiophile might disagree, but my ears aren't what they were in the 1970's. Enjoy.
