SPL - Sound Performance Lab Phonos duo Phono Preamplifier

SPL Phonos duo phono preamplifier

The versatile RIAA phono preamplifier

With the Phonos duo, SPL presents an enhanced version of the proven Phonos phono preamplifier.

Ready for MM and MC systems

Equipped with balanced and unbalanced inputs and outputs, it is compatible with turntables that use moving magnet (MM) or moving coil (MC) cartridge systems.

SPL's own technologies

Thanks to integrated SPL VOLTAiR technology and the precise RIAA equalization filter in the renowned Douglas Self design, the Phonos duo delivers exceptional sound quality. Six selectable capacitance levels for MM and six impedance levels for MC systems allow optimal adaptation to a wide variety of cartridges – for maximum flexibility and the best possible performance.

Slim and chic

The Phonos duo also impresses visually: It fits seamlessly into the SPL HiFi “Professional Fidelity” line and is available in the classic housing colors black, red and silver.
