Phonos duo
The RIAA Phono Preamplifier – Twice as nice
The SPL phono preamplifier Phonos duo expands the established
SPL phono preamplifier Phonos with a pair of balanced stereo inputs and outputs.
Phonos duo is thus even more versatile.
Whether moving magnet (MM) or moving coil (MC) cartridge systems –
the SPL VOLTAiR technology and the RIAA filter in the legendary Douglas-Self design
form the fundament for an outstanding phono sound.
