PHONO CARTRIDGE LOADING ADJUSTMENT
The phono cartridge load can be adjusted to suit your particular phono cartridge, using two pairs of
internal blue mini-switches.
The Jarrah mini-switches are factory set to a 47kΩ load. Also, switch 1 is set in the on position. This is a
220pF capacitive setting and is usually required for RF suppression. It is not recommended that you turn
switch 1 off.
Disconnect the lead from the IEC socket on your Plinius Jarrah. Carefully remove the lid by undoing the
six cap screws. Locate the blue mini-switch banks to the rear of the circuit board. Adjust the settings of
the five individual switches (remember to do both channels) to give a loading required with reference to
the table below.
