The ART DJ Pre II Phono Preamp is an RIAA phono preamplifier. The DJ PRE II 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 the response of the turntable cartridge. It features a switchable filter to prevent unwanted noise caused by the rotation of the platter. The front gain adjustment control and signal/clip LED allow you to optimize the preamplifier gain for a wide range of input sources. The built-in low-noise phono preamplifier circuit is highly accurate and conforms to the RIAA standard. The line outputs are low impedance and can be used with any sound card.
