SPL Phonos ProFi Preamplifier

SPL Phonos ProFi Preamplifier

RIAA Phono Preamplifier

This phono preamplifier for Moving Magnet (MM) and Moving Coil (MC) pickup systems is based on the legendary Douglas-Self-Design.

MM & MC

There are two pickup systems for record players: Moving Magnet (MM) and Moving Coil (MC).

Moving Magnet

Moving magnet pickups generate a small voltage by moving a magnet between copper coils. MM pickups have a very high inductance and impedance.

Moving Coil

The MC pickup is also a small electromagnetic generator, but with the magnets firmly anchored and the coils moving between them, i.e. exactly the opposite of the MM pickup.

Amplification

The pre-amplification can be switched in three values. The normal gain value is +46 dB for MM and +67 dB for MC cartridges.

In the -10 dB position, the phono produces enough output level for normal hi-fi equipment operating at a reference level of -10 dBV.

In the +4 dB position, the output level is about as loud as that of modern DA converters at a reference level of 0dBfs = +15 dBu.

Subsonic Filter

The rumbling of the turntable’s drive mechanism is also amplified by the high amplification of the bass range due to RIAA equalization in playback. The Phonos offers a switchable subsonic filter to remove this rumble. 

Connections

Gold-plated RCA sockets are available for connecting the turntable and for outputting to a preamplifier such as the Director Mk2 or the Elector. 

A ground connection for the turntable is designed as banana plug socket. The ground lead can be either clamped or plugged in.
