Using the Bellari VP29 Solid State Phono Preamp is easy. First, connect your turntable to the input using the stereo RCA jacks. Then, connect the preamp's output to your amplifier or receiver using the available output options (stereo RCA jacks or 1/8' TRS stereo). Plug in the included AC adapter to power it on. You'll see the power LED indicator light up. This preamp works well with moving magnet and high - output moving coil cartridges. Just make sure your turntable needs a pre - amp. As for maintenance, keep it in a dry and clean place. Avoid exposing it to extreme temperatures or moisture. If you have any issues or need more details, refer to our Beginner's Guide To Turntables.
