SPL - Phonos Duo  (Pre-Order)

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.

Moving Magnet

Moving magnet cartridges generate a voltage by moving a magnet between copper coils. In order to achieve the best possible linearity of the frequency and phase response, the capacitance is modified to adjust the cartridge.
Phonos duo offers six different capacities for this adjustment:

12 pF, 47 pF, 100 pF, 150 pF, 220 pF und 330pF.

Moving Coil

The moving coil cartridge is also a small electromagnetic generator. However, the magnets are firmly anchored – and the coils move between the magnets. This concept is exactly the opposite of the moving magnet cartridge. Consequently, it is not the capacitance but the impedance that is the decisive parameter in matching the cartridge.

Phonos duo offers six different impedances for this adjustment:
20 ohms, 50 ohms, 100 ohms , 220 ohms, 500 ohms and 1 kohm.
