Input Impedance Settings
Most cartridge manufacturers provide the recommended load impedance for their
cartridges. The Athens 2’s inputs should be set to match this recommended figure as
closely as possible.
4 dip switches adjust the input impedance and more than one dip switch can be
turned on at the same time.
The 4
dip switches that adjust the input impedance are marked on the panel as ‘Z’.
The picture below shows the required position of the Z dip switches for specific input
impedances.
