PrecisionPowerPCX™ amplifiers no longer need an optional QPORT™ to connect multiple QBASS PLUS™ equipped amplifiers while using one QBASS REMOTE™. The new QBASS PLUS™ circuitry in the PCX™ amplifiers is now positioned before the crossover circuit. In doing this, PrecisionPower engineers have allowed you to daisy chain your RCAoutput to the next amplifier input, causing the first amplifier’s Q BASS Remote™ to become the master control amplifier. See your Authorized PrecisionPower Dealer for more information! (See diagram pg.18)
