The PSA series stands for two important tenets of professional amplification: performance and reliability. Due care has been taken to ensure that these amplifiers perform 100% whenever they are called upon. Their innovative modular construction, pro-active protection mechanisms for both amplifier and loudspeaker, extended peak power ability, and generous usage of large fans and heat sinks, are some of the solid foundations of the series. The PSA 801 B - bi-amp with built in active crossover leads the pack also comprising two hefty dual amps, the 601 and the 1000.
