Excellent working unit

The Avlex SPX-3 is a professional 3-way stereo audio crossover designed for live sound reinforcement, studio monitoring, and commercial sound installations like house of worship systems. Part of the vintage Avlex SPX rackmount signal processor series—which also includes the SPX-2 equalizer and the SPX-5 compressor—it separates audio signals into low, mid, and high frequency ranges to correctly route sound to subwoofers, mid-range speakers, and high-frequency tweeters.

Key Features and Specifications

  • Signal Routing: Functions natively as a 3-way stereo crossover.
  • Form Factor: Built into a standard 1U rack-mountable metal chassis for integration into touring racks or installations.
  • Connectivity: Features professional-grade inputs and outputs on the rear panel, accommodating standard XLR or 1/4" TRS connections common to pro-audio gear from this era.
  • Front Panel Controls: Includes dedicated knobs for adjusting crossover frequency split-points, alongside individual output level controls for precise volume matching between speaker components
