Commentary
An MPA series power amplifier developed to bring out the performance of JBL's PA speaker system.
It is equipped with a protection output limiter with limiter characteristics that perfectly match the power compression characteristics.
This allows natural output control without distortion without losing the acoustic power of music.
An optional input module was available to add various functions such as a 2-way 2-channel channel divider, a high-pass filter for a subwoofer, and a microphone amplifier with a mixing function.
