Ortofon SPU Moving Coil Cart ridge
Thank you for choosing an Ortofon SPU
moving coil cartridge for your turntable.
Original
The original Or tofon stereo cartridge was
born in 1958. Ever since, Ortofon SPU
cartridge models have shared the DNA from
their SPU ancestor, being true to the never
compromised original design.
The model in this manual share the authentic
so-called “Ortofon Sound” worldwide
recognised and related to the Ortofon
cartridges.
Re nements on the models have taken
bene t from the use of new materials, to gain
the outstanding reproduction qualities.

Mounting
All SPU cartridges are designed to
bring optimum performance, when the
tonearm mounted with the cartridge is
adjusted parallel to the record surface, at
recommended tracking force.
Maintenance
To obtain optimal sound reproduction,
remove dust from the stylus regularly by
using a st ylus brush. Guide the brush gently
forward in the direction of the diamond tip.
From time to time, the car tridge system
should be removed from the tonearm, and the
gold-plated contact points on the cartridge,
and the contact points inside the tonearm,
should be cleaned with a small amount of
propyl alcohol. This helps to avoid dust
or stick y material from resulting in a bad
electrical connection.
