This is the ART DJPRE II Phono Preamplifier.
The DJ PRE II (formerly named the “Phono MicroPRE”) acts as an interface between your turntable and your audio recording / playback system. The analog input capacitance can be switched between 100pF and 200pF to optimize your phono cartridge response.
A switchable low cut filter removes turntable rumble while leaving the audio pristine. The front gain trim control and signal/clip LED allow you to optimize the preamp’s gain for a wide range of input sources. The built-in low noise phono preamp circuitry is highly accurate and precisely conforms to the RIAA standard. The line output jacks are low impedance and can be used with any sound card.
