Description

The JBL M553 is a professional 3-way stereo electronic crossover designed for precision audio control in sound reinforcement systems. It offers adjustable crossover frequencies, individual level controls, and high-quality components to ensure clean signal separation and optimal performance across low, mid, and high frequency ranges. Ideal for use in live sound and installed audio setups.

Features

  • Distortion: Very low distortion (THD 0.004%).

  • Level Controls: Individual level controls for each frequency band allow for precise adjustments. 
  • Mute Functions: Each output has a mute function with an indicator LED.
