dbx 223xs - Dual-Channel 2-Way Stereo/3-Way Mono Crossover with XLR Inputs/Outputs and LED Indicators in White Finish

The dbx 223xs Dual-Channel 2-Way Stereo/3-Way Mono Crossover represents a pinnacle of audio processing technology, reflecting dbx's extensive expertise and four decades of industry leadership. Designed to optimize speaker performance and deliver pristine audio, the 223xs utilizes advanced precision filters to effectively manage frequency distribution across your audio system. This ensures that each loudspeaker driver receives the appropriate frequency range, maximizing amplifier efficiency and minimizing distortion for a cleaner, more accurate sound.

As a dual-channel crossover, the dbx 223xs offers flexibility with its ability to operate in both 2-way stereo and 3-way mono modes. The unit is equipped with high-quality XLR inputs and outputs, ensuring balanced and reliable signal connections. The inclusion of Linkwitz-Riley 24dB per octave filters, a professional standard for crossovers, allows for smooth and precise frequency separation, minimizing phase issues and optimizing sound quality.

Key features of the dbx 223xs include independent output gain controls for level matching, which facilitate precise adjustments to ensure consistent audio levels across different outputs. The crossover also provides a phase reverse switch on all outputs, which can correct phase anomalies and improve system coherence. Additionally, a 40Hz high-pass (low cut) filter on both channels helps to eliminate unwanted low-frequency noise, enhancing overall sound clarity.

The dbx 223xs offers an x10 range switch on both channels, allowing users to multiply the crossover frequency range by ten, thus expanding the crossover's versatility for various applications. For low-frequency management, the unit features a low-frequency summed (subwoofer) output, which can be optionally enabled to accommodate subwoofer setups. The front panel is designed with intuitive "click" controls and LED indicators, including status LEDs for stereo/mono operation, low cut, and x10 settings, as well as phase invert indicators, making it easy to monitor and adjust settings.

Constructed in a sleek white finish, the dbx 223xs is housed in a durable 1U steel chassis, measuring 19 x 6.9 x 1.75 inches, and weighs just 3.7 lbs. This compact and lightweight design ensures that the unit integrates seamlessly into rack-mounted setups while withstanding the demands of professional use. It operates on a wide range of voltages (100-240VAC at 50/60Hz), making it suitable for international applications. The 223xs is CSA NRTL/C approved and CE compliant, underscoring its adherence to high safety and performance standards.

In summary, the dbx 223xs Dual-Channel 2-Way Stereo/3-Way Mono Crossover offers exceptional performance and versatility. With its advanced filtering capabilities, flexible operation modes, and user-friendly design, it stands as an invaluable tool for achieving optimal sound quality in a variety of audio settings.
