Description

Upgrade your vinyl listening experience with the Fosi Audio BOX X4. This high-fidelity phono preamp and headphone amplifier is designed for MM turntable users who demand audiophile-grade clarity. By utilizing low-noise JAN 5725W vacuum tubes, the BOX X4 provides a warm and pure analog sound for your record player. It serves as a professional-grade MM phono stage that helps you get the most out of your phonograph system. This versatile device offers dual-output flexibility to suit your setup. You can connect it to your existing amplifier via RCA line-level outputs or plug your headphones directly into the 3.5mm jack for private listening sessions. With dedicated volume, bass, and treble controls, you can easily tailor the audio to your preference. The built-in grounding terminal helps eliminate hum, ensuring a clean signal for your music.

Key Features

Pro-Grade MM Phono Stage: Delivers audiophile-grade clarity for MM turntables using low-noise JAN 5725W vacuum tubes for pure analog playback.

Dual-Output Functionality: Switch between RCA line-level output for your main amplifier and a 3.5mm headphone output for private listening.

Integrated Grounding Terminal: Includes a built-in earth terminal to eliminate unwanted hum and protect your vinyl playback system.

Customizable Audio Controls: Easily adjust your sound profile with dedicated knobs for volume, bass, and treble settings.

Versatile Headphone Driving: Engineered to drive most headphones, making it an ideal choice for late-night vinyl sessions without disturbing others.
