PA8, setting of phono card
To ensure that the phono card works in an optimal way, it must be set according to the requirements of the
cartridge. Please refer to the operating manual / technical data of your cartridge to find out the correct
settings. The setting is done by switches on the pcb. The upper switches are for the left channel, the lower
for the right channel. The switches for both channels must be set identically. You can set: sensitivity,
cartridge (MM or MC) and cartridge load. For fine tuning of sensitivitiy see additionally the level function of
the PA8 (see 3.4.1 Setting of input sensitivity).
