MM/MC phono stage with VOLTAiR technology, RCA and XLR connections and extended capacitance and impedance settings.
Phonos Duo: the design
The Phonos Duo has RIAA equalisation to a Douglas Self design, six capacitance values for MM (12 to 330 pF) and six impedance values for MC (20 ohms to 1 kohm). Output gain has three positions in 10 dB steps. Input and output are on gold-plated RCA and XLR connectors.
Like the other SPL components it uses VOLTAiR technology: the audio circuits run on ±60 V rails, with discrete op-amps of SPL's own design and a shielded toroidal transformer.
