Ortofon SPU-moving coil cartridges

Thank you for choosing an Ortofon SPU­cartridge for your turntable.
All Ortofon SPU-cartridge models are highly
indebted to their SPU-ancestor launched
in 1958, when the original Ortofon stereo­cartridge was born.
So, ever since the various Ortofon SPU­models announced in this manual, have
never compromised with the basic design

- responsible for the so-called “Ortofon
Sound”, world wide related to these
cartridges. Refinements on the models have
taken bene fit from the use of new materials
and impro ved stylus types, to gain the
outstanding reproduction qualities.

Mounting

All SPU-cartridges are designed to
bring optimum performance, when the
tonearm moun ted with the cartridge is
adjusted parallel to the record surface, at
recommended tracking force.

When antiskating adjustment is possible, we
recommend a 50% higher value, when using
SPU-cartridges with the Ortofon Replicant
stylus, compared to normal setting at
recommended tracking force.

Maintenance

To obtain optimal sound reproduction,
remove dust from the stylus regularly by
using a small bruch.
Guide the brush gently forward in the
direction of the diamond tip.
From time to time also remove the cartridge
system from the tonearm and clean the gold
plated contact points with a small amount
of propyl alcohol. Also the contacts inside
the tonearm will need this type of cleansing,
to avoid dust or sticky material to result in
annoying disconnection.
We do not recommend the use of propyl
al cohol for cleansing the record surface, as
resolved materials will stick to the stylus.

As a consequence the Ortofon warranty - in
such cases - may not be valid.

Special Repair service

Owing to the design of the SPU moving
coil cartridge, the stylus is not part of a
replaceable assembly and therefore we offer
Special Repair service for the SPU Series
cartridges. Special Repair service is available
through our webshop:
www.ortofon.com/hifi/products/repair-service
and Ortofon Authorized dealers:

Warning

This phono cartridge is only for mounting
on tonearms and must not be used for other
purposes.
