Easy Switching Between Up to Three Analog Audio Sources!

The Fosi Audio P4 is a compact three-input preamplifier developed in response to requests from customers and users around the world and based on the V3 stereo amplifier. Its full aluminum-alloy chassis delivers solid build quality and increased resistance to electromagnetic interference.

The preamp features a high-precision motorized analog potentiometer that not only provides smoother volume control but also reduces noise and distortion, resulting in a cleaner sonic picture.

Separate bass and treble controls let you fine-tune the sound to your preference. The bypass switch defeats the tone controls to guarantee the purest Hi-Fi playback. The three-step gain setting (Gain 3 dB/6 dB/9 dB) lets you optimally use different output levels from audio sources.

The included multifunction remote is compatible with various Fosi Audio products.
