FOSI AUDIO P4 Audio preamplifier Black

The Fosi Audio P4 is a compact stereo mini preamplifier with three RCA inputs, ideal for switching between different audio sources such as a CD player, turntable (with its own phono preamp), TV, or Bluetooth receiver. Via the single RCA output, you can easily send the signal to an amplifier, active speakers, or a subwoofer. The passive design ensures a pure signal transmission without noise or distortion, while you control the volume and select the desired source on the front panel.
