Adjust the horizontal inclination (azimuth) of the cartridge so that the shell’s cartridge sharp
side edges and their reflection on a record surface (or by using a mirror) form straight and
coincident lines or are perpendicular to the record surface.

The output terminals are arranged as shown in
Fig. 4
. Insert the output terminals of the
cartridge in the lead tips of the head shell. The leads are colored or coded for identification.
Make the correct connections.
Caution: If the output terminals of the cartridge are heated with a soldering iron, internal open
circuit can result. Be sure to use lead tips.

Adjusting stylus pressure
Also known as the Vertical Tracking Force (VTF). The optimum stylus pressure is 2.5 g. ± 0.3 g. In the
case of an unwarped record in good condition, the stylus pressure may be reduced to 2.2 gr. For a
record made at a high recording level or when played under a low ambient temperature, the stylus
pressure should be increased to 2.8 g. maximum. Generally, the individual characteristics of the
cartridge have been determined at an ambient temperature of 20°C or thereabouts. Of course, the
cartridge may be used over a wide temperature range, but you will obtain the best reproduction if you
use it at the standard temperature or its vicinity.
Caution: Note that if an iron turntable platter is used, an excessive stylus pressure might be applied
due to magnetic attraction.

Output voltage
The output voltages are 0.35 mV (
Nitro1
) and 0.30mV (
Nitro2
). Since these are low relative to an MM
type cartridge, your system must have a MC phono input or you will either need a MC head amp or a
step-up transformer (SUT).
