• Terminating resistor: 30 Ohm effective resistance
• Induction:
• Recommended tracking force: 1.5 ± 0.3 g (At 20 - 25 °C. Adjust to 1.8 g if room temperature is less than 20 °C).
• Vertical tracking angle: 20 ± 2°.
• Needle compliance: dynamic: 11 x 10-6 cm/dyme (horizontal), 9 x 10-6 cm/dyme (vertical) and static: 21 x 10-6 cm/dyme (both at 100 Hz, 25 °C).

System connections:

• • white signal line: L+
  • blue signal line: L-
  • red signal line: R+
  • green signal line: R-

Remarks

• The output voltage of the MC-9 is only 0.3 mV, i.e. about 1 tenth of the voltage generated by a magnetic system (MM = Moving Magnet). If the amplifier does not have a built-in MC preamplifier (MC phono input), one must use an intermediate amplifier (so-called matching transformer) - also called phono preamplifier, turntable preamplifier, phono equalizer preamplifier - for MC systems.
