Using the Bellari VP130 MK2 Tube Phono Preamp is easy. First, connect your turntable to the dual RCA inputs. Then, connect your speakers or headphones. You can control the output volume and headphone volume separately. Use the mute switch when you need a break from the sound. Make sure to ground the preamp properly using the grounding connection. When choosing a cartridge, it works well with Moving Magnet (MM) cartridges or high output Moving Coil. For maintenance, keep it in a dry and clean place. Avoid exposing it to extreme temperatures or humidity. If you're not using it for a long time, unplug the power supply. With proper use and care, this preamp will serve you well for years.
