How to Pair the Fosi Audio Luna3 Turntable with an Amplifier

Quick Answer

Connect the Fosi Audio Luna3 to an amplifier using RCA cables. If your amp lacks a phono input, you will need a separate phono preamp between the turntable and amplifier.

Step-by-Step Setup

1. Check Your Amplifier Inputs: Identify whether your amplifier has a phono input or only line-level (AUX, CD, Tape) inputs. The Luna3's built-in preamp outputs line-level signal, so use a line-level input. Never plug the Luna3 into a phono input—this will cause double amplification and distorted sound.
2. Connect the RCA Cables: Use a standard stereo RCA cable (red and white plugs). Connect the Luna3's output jacks to the selected input on your amplifier. Ensure the left and right channels match. If you hear hum or buzz, try a shielded RCA cable and keep the cable away from power cords.
3. Set the Ground Wire (If Needed): Some amplifiers have a ground screw. If you hear a low hum, connect the Luna3's ground wire (usually a thin wire with a spade connector) to the amplifier's ground terminal. Not all setups require the ground wire—only use it if you notice a ground loop hum.
4. Power On and Adjust Volume: Turn on the amplifier first, then power the Luna3. Start with the amplifier volume low, play a record, and gradually increase to a comfortable listening level. If the sound is very quiet or distorted, double-check that you are using a line-level input and not a phono input.
