Stand-By
The button on the left hand side of the front panel alternately turns the power on or returns it to standby mode.
The blue LED above the stand-by push button shows that the unit is switched on.
Settings
The three push buttons on the left hand side are used to set input impedance, input capacitance and input gain.
To find out which type your cartridge is please consult the literature accompanying your cartridge. The
literature for cartridges should also specify the correct input impedance (low-output MC cartridges) and the
correct input capacitance (high-output MC and MM cartridges), into which the cartridge is designed to work.
If in doubt please consult your dealer.
