RDL ST-CX2 Band Active Line-Level Crossover

Optimize audio clarity and control in pro AV, paging and security monitoring systems with the Radio Design Labs ST-CX2 two-band active line-level crossover. Designed as a professional audio processor, the ST-CX2 separates full-range and woofer signals while providing adjustable equalization to reduce midband congestion and enhance intelligibility — ideal for surveillance audio, paging, and conferencing environments. The FULL RANGE output covers 100 Hz to 30 kHz with a center EQ at 2 kHz, while the WOOFER output provides 40 Hz to 165 Hz with a dedicated 50 Hz boost for tight low-frequency response. Balanced inputs and outputs (with unbalanced compatibility) simplify integration into existing racks, and the LOOP THRU lets you hook up an ST-CX2S subwoofer crossover for expanded systems. RDL’s SupplyFlex power input accepts 24 V DC for installation flexibility and low-noise, low-distortion performance preserves signal fidelity for monitoring and recording. Compact and rugged, the ST-CX2 is a practical choice for installers demanding reliable crossover control in AV, security, and surveillance projects. Specify the ST-CX2 for clearer speech, punchier bass, and simpler system tuning — order now for your next monitoring or paging installation.
