234S

Versatile Crossover Configuration: Supports stereo 2-way, stereo 3-way, or mono 4-way operation for maximum flexibility.

Precision Filters for Clean Sound: Uses Linkwitz-Riley 24 dB/octave filters for smooth, professional-grade crossover performance.

Subwoofer Output Option: Includes a mono-summed low-frequency output to drive subwoofers with impact and clarity.

Switchable Low-Cut Filter: Built-in 40 Hz high-pass filter helps eliminate unwanted rumble from the signal.

Phase and Gain Controls: Each output features independent level and phase invert switches for perfect system tuning.

x10 Frequency Range Switch: Multiplies crossover frequency range for use with mid-high or high-frequency drivers.

Clear LED Indicators: Visual feedback for mode, filter settings, and output phase makes setup intuitive.

Balanced TRS Inputs and Outputs: Ensures clean signal transfer and compatibility with pro audio gear.

Rugged, Rack-Ready Design: Built for touring and installed sound with a compact 1U chassis and durable construction.
