Operational Details System Example
The system below has a “master” QX300.1 amplifier that controls all the of signal processing for
the “slave” QX300.1 amplifiers downstream. The LPL, bass boost, crossover and subsonic filter on
the “master” amplifier will effect all “slave” amplifiers. Please keep in mind each amplifier must still
have its own sensitivity level individually adjusted regardless if its a “master” or “slave” amplifier.
