MC Impedance
Selector
Turn off power before removing
cabinet top plate.
The impedance selector is a
super high grade socket using
removeable gold-plated jumpers
to secure lasting superior con-
tact. The selector has 6 positions
marked on the circuit board.
Position 1
10 Ohm
Position 2 40 Ohm
Position 3 80 Ohm
Position 4 300 Ohm
Position 5 800 Ohm
Position 6 47 kOhm
See figure 3
Custom Loads
Besides these values it is possi-
ble to load the cartridge with any
impedance between 10 Ohm
and 47 kOhm, by inserting resis-
tors in the sockets found on the
PC board just left of the imped-
ance loading socket (as seen
from the rear) RIN 1/RIN 2.
