AD-234XS 2/3/4-Way Active Crossover

The AD-234XS 2/3/4-Way Active Crossover is a high-performance, professional-grade solution for optimizing multi-way sound systems. Designed for both stereo and mono operation, this crossover delivers exceptional audio clarity, superior signal management, and flexible configuration options—making it ideal for live sound, studios, stage setups, and installed PA systems.

High-Quality Inputs and Outputs

The AD-234XS features XLR connectors for both input and output, supporting electronically balanced/unbalanced connections and RF filtering to eliminate signal interference. With an input impedance of >50k ohm (balanced) and >25k ohm (unbalanced), it accommodates a wide range of audio sources. The maximum input level exceeds +22dBu, allowing it to handle high-output signals without distortion.

The output section includes impedance-balanced/unbalanced XLR connectors, with a balanced output impedance of 60 ohm and 30 ohm unbalanced. It supports a maximum output level of >+21dBu into loads of 2k ohms or greater, ensuring strong signal integrity throughout the signal chain.

Outstanding Audio Performance

This unit delivers a bandwidth of 20Hz to 20kHz (±0.5dB). It also offers an extended frequency response of <3Hz to >90kHz (+0/-3dB), covering the full audio spectrum with high accuracy. The dynamic range exceeds 106dB (unweighted), providing excellent headroom. With a signal-to-noise ratio referenced to +4dBu, the AD-234XS ensures clean and noise-free signal processing.

Total Harmonic Distortion + Noise (THD+N) is impressively low at <0.004% at +4dBu, 1kHz and remains under 0.04% even at +20dBu, delivering clean, transparent sound even at high volume levels. The unit also features a Common Mode Rejection Ratio (CMRR) of >40dB, typically >55dB at 1kHz, minimizing ground loop interference.

Flexible Crossover Configuration

The AD-234XS supports both stereo 2-way or 3-way and mono 4-way crossover configurations, with adjustable crossover frequencies ranging from 45Hz to 9.6kHz using the x10 range setting. It utilizes Linkwitz-Riley 24 dB/octave filters, ensuring smooth phase alignment and accurate driver control in complex speaker systems.

Reliable Construction and Power

Operating on 230V AC at 50/60Hz, this unit fits easily into any rack setup. It comes packed at 65mm x 560mm x 290mm, with a net weight of 1.8kg and gross weight of 2.6kg, making it portable yet rugged enough for touring or fixed installations.
