2. Setup Instructions

Follow these steps to correctly set up your U-Turn Audio Pluto 2 Phono Preamp:

1. Placement: Place the Pluto 2 on a stable, flat surface near your turntable and amplifier/receiver. Ensure it is away from sources of electromagnetic interference.
2. Connect Turntable to Pluto 2: Connect your turntable's RCA output cables to the PHONO IN RCA jacks on the rear of the Pluto 2. Ensure the left (white) and right (red) channels are correctly matched.
3. Connect Ground Wire: Connect your turntable's ground wire to the GROUND terminal on the Pluto 2. This is crucial for minimizing hum and static.
4. Connect Pluto 2 to Amplifier/Receiver: Connect the LINE OUT RCA jacks on the Pluto 2 to a line-level input (e.g., AUX, CD, TUNER) on your amplifier or receiver. Do not connect to a PHONO input on your amplifier/receiver, as this will result in over-amplification and distorted sound.
5. Connect Power: Plug the included power adapter into the POWER input on the Pluto 2, then plug the adapter into a wall outlet. The Pluto 2 does not have an on/off switch and will power on automatically.
