  • Induction:
  • Recommended contact force: 1.5 ± 0.3 g (At 20 - 25 °C. At less than 20 °C Room temperature up to set 1.8g.)
  • Vertical track 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 (each at 100 Hz, 25 °C), which is about 18^-6 cm/dyne(horizontal) or about 16^-6 cm/ dyne (vertical) at the international (but not at Yamaha!) the usual 10 Hz.
  • System connections:
    • white signal line: L+
    • blue signal line: L-
    • red signal line: R+
    • green signal line: R-
  • white signal line: L+
  • blue signal line: L-
  • red signal line: R+
  • green signal line: R-
  • The output voltage of the MC-9 is only 0.3 mV, i.e. about 1 tenth of the voltage generated by a magnet system (MM = Moving Magnet). If the amplifier does not have a built-in MC preamplifier (MC phono input), you have to use an intermediate amplifier (so-called matching transformer) - also called phono preamplifier, turntable preamplifier, phono equalizer preamplifier - for MC systems.
