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

The dbx 234s Dual-Channel 2/3-Way Stereo/4-Way Mono Crossover is engineered to provide top-tier performance and precision for professional audio systems. Drawing on dbx's extensive experience in audio processing, the 234s ensures that your speakers receive the optimal frequency ranges, enhancing sound clarity and reducing distortion by allowing amplifiers to focus on the most effective signal output. This crossover is designed to handle a variety of setups, making it a versatile tool for both live sound and studio applications.

The dbx 234s features advanced Linkwitz-Riley 24dB per octave filters, a professional standard that ensures smooth and accurate frequency transitions between different speaker drivers. The unit supports both 2-way stereo and 3-way mono configurations, and its mode switches allow for easy adaptation to various audio setups. In addition, the crossover provides a low-frequency summed (subwoofer) output for effective subwoofer integration, which is crucial for achieving a balanced sound across the frequency spectrum.

Equipped with TRS (Tip-Ring-Sleeve) connectors, the dbx 234s offers differentially balanced inputs and outputs, contributing to reduced noise and enhanced signal integrity. The crossover's precision controls include independent output gain controls for level matching, phase inversion switches for each output to address phase issues, and a 40Hz high-pass (low cut) filter to eliminate unwanted low-frequency noise.

The dbx 234s also features a x10 range switch on both channels, which expands the crossover frequency range by a factor of ten, providing greater flexibility in adjusting frequency settings. The front panel includes intuitive "click" controls and a range of LED indicators that signal the unit's operating mode, including stereo/mono status, low cut activation, and phase inversion. These visual cues make it easy to monitor and adjust the crossover's settings in real-time.

Designed with durability in mind, the dbx 234s comes in a sleek white finish and is housed in a robust 1U steel chassis, measuring 19 x 6.9 x 1.75 inches and weighing 4 lbs. This compact form factor ensures the crossover integrates seamlessly into rack-mounted systems. The unit operates on a broad voltage range (100-240VAC at 50/60Hz) and has a power consumption of just 15 watts, making it suitable for various international applications. Additionally, the dbx 234s is CSA NRTL/C approved and CE compliant, reflecting its adherence to high safety and performance standards.

Overall, the dbx 234s Dual-Channel 2/3-Way Stereo/4-Way Mono Crossover is a highly reliable and versatile tool for achieving optimal audio performance. Its advanced features, high-quality components, and user-friendly design make it an excellent choice for professionals seeking to enhance their sound systems.
