TriAmp systems are either:
3-Way speakers designed to have each system component (High Frequency/Mid Frequency/Low Frequency sections) individually powered by three separate amplifier channels. This configuration provides the system’s maximum sound pressure level (SPL) for larger auditoriums and allows for both input level adjustment and the application of precise electronic crossover frequencies and time alignment for all system components on an individual basis.
OR
4-Way systems equipped with a Klipsch Passive Processor that allows the four system components (High Frequency/Mid Frequency, Mid Bass and Low Frequency sections) to be powered by three separate amplifier channels instead of four. This system type still allows some input level adjustment and adjustment of electronic crossover frequencies and time alignment of system components with a less complicated setup requiring less wire runs due to a reduced number of amplifier channels being used and takes advantage of the fact that most HF/MF components require similar amplifier power.
