Before turning the amplifier on please read the following sections to make sure that the unit is set up 
properly for your specific application.

The gain of the fP 2400 is fixed to 32 dB 

RKNKO= pÉåëáíáîáíó=

Sensitivity is defined as how many volts (rms) or dBu (referred to 0.775Vrms) are required to get full 
output power. As the output power varies with the load impedance, usually 4 ohms is the reference. But 
in the case of an MLS-switch equipped amplifier there are many choices for full output level in different 
load impedances.
