SPL Phonos Duo (Black)

The SPL Phonos duo Black is a premium RIAA phono preamplifier designed for Moving Magnet (MM) and Moving Coil (MC) cartridge systems. Utilizing SPL VOLTAiR technology and the acclaimed Douglas-Self RIAA filter, it delivers extraordinary sound clarity and fidelity. With both balanced (XLR) and unbalanced (RCA) inputs and outputs, it provides versatile connectivity for high-end audio setups.

Equipped with six selectable capacitance settings for MM and six adjustable impedance options for MC, the Phonos duo Black ensures perfect adaptation to your cartridge's requirements. Additional features include a subsonic filter to reduce low-frequency rumble, a Mono switch for enhanced mono playback, and a Ground Lift switch to eliminate ground loops. Its sleek black design complements any audio system, providing both elegance and exceptional performance.
