• 3-Way Stereo: Adds a mid-frequency split for three-band audio control.
• 4-Way Mono: Combines both channels to split into four frequency bands, perfect for complex mono systems.

A convenient mode switch lets you toggle easily between these configurations, allowing one unit to serve multiple purposes depending on the application.

Precision Filtering for Professional Audio

The dbx 234 / 234XL includes Linkwitz-Riley 24 dB/octave filters, a professional standard known for maintaining phase alignment between frequency bands. These filters provide a smooth crossover transition, ensuring that your audio remains clean and undistorted across all output channels.

Additionally, a 40 Hz high-pass filter on both channels protects low-frequency drivers by filtering out unnecessary subsonic content, improving system longevity and performance.

Advanced Control and Monitoring

This crossover offers a full suite of user controls for precise tuning:

• Individual Output Level Controls: Set the perfect output levels for each band to maintain balanced sound.
• Phase Reverse Switches: Available on all outputs to resolve phase cancellation issues and enhance clarity.
• x10 Frequency Range Switch: Expands crossover frequency selection to accommodate a broader range of speaker systems and venue types.

Clear LED indicators show system status, including stereo/mono mode, for quick monitoring during setup or operation.

Dedicated Subwoofer Output

For systems requiring enhanced low-frequency reinforcement, the dbx 234 / 234XL features a low-frequency summed output. This allows easy integration of a subwoofer by combining both stereo channels’ low-end content into a single mono output, ideal for bass management in large sound setups.

Use Case

This active crossover is well-suited for:

• Public address systems
• Live concerts and stage sound reinforcement
• Studio monitoring configurations
• Installations requiring precise audio frequency distribution
