dbx 234xs - Dual-Channel 2/3-Way Stereo/4-Way Mono Crossover with XLR Inputs/Outputs and LED Indicators in White Finish

The dbx 234xs Dual-Channel 2/3-Way Stereo/4-Way Mono Crossover exemplifies precision and performance in audio signal processing. Leveraging dbx's four decades of expertise in creating premium audio processors, the 234xs is engineered to enhance your audio system by effectively directing frequencies to the appropriate speaker drivers. This process ensures that amplifiers operate more efficiently by handling only the relevant frequency ranges, leading to a clearer and more distortion-free sound.

At the core of the dbx 234xs are advanced Linkwitz-Riley 24dB per octave filters, renowned in the industry for their accuracy and smooth transitions between frequency bands. The crossover supports versatile configurations, including 2-way stereo, 3-way stereo, and 4-way mono operation, making it adaptable to a wide range of audio setups. It features mode switches on the rear panel that allow for quick adjustments between stereo and mono modes, while the x10 range switch enables an expanded frequency range for both channels.

The dbx 234xs is equipped with XLR balanced inputs and outputs, ensuring high-quality signal transmission with minimal noise. The unit includes individual output level controls for precise level matching, and phase invert switches on each output to correct phase issues that may arise in complex audio setups. Additionally, a 40Hz high-pass (low cut) filter is provided to eliminate unwanted low-frequency noise from both channels.

Additional features include a low-frequency summed (subwoofer) output for effective integration of subwoofers into your system. The front panel of the 234xs is designed for ease of use, with "click" controls and LED indicators that clearly show the unit's operating status. These indicators include green LEDs for stereo operation, yellow LEDs for mono operation, red LEDs for low cut activation, and additional red LEDs for phase inversion. This intuitive interface ensures you can monitor and adjust settings quickly and accurately.

Constructed in a sleek white finish and housed in a durable 1U steel chassis, the dbx 234xs measures 19 x 6.9 x 1.75 inches and weighs 4 lbs, making it a compact yet robust addition to any audio rack. It operates on a broad voltage range of 100-240VAC at 50/60Hz with a power consumption of just 15 watts, making it suitable for international use. The unit is also CSA NRTL/C approved and CE compliant, reflecting its adherence to high safety and performance standards.

In summary, the dbx 234xs Dual-Channel 2/3-Way Stereo/4-Way Mono Crossover is a high-performance, versatile tool designed to optimize audio signal distribution and enhance the overall sound quality of your PA system or studio setup. Its advanced features, high-quality components, and user-friendly design make it a valuable asset for audio professionals.
