1. Introduction
This manual provides comprehensive instructions for the Behringer SUPER-X PRO CX2310, a high-precision stereo 2-way/mono 3-way crossover with a dedicated subwoofer output. Designed for professional audio applications, this device accurately divides audio signals into different frequency bands, optimizing sound reproduction through multiple loudspeakers.
The CX2310 ensures precise frequency separation, allowing each speaker component (e.g., woofers, mid-range drivers, tweeters, subwoofers) to receive only the frequencies it is designed to reproduce efficiently. This results in improved sound clarity, increased system efficiency, and enhanced speaker protection.

- INPUT GAIN: Adjusts the input sensitivity for the respective channel.
- CLIP LED: Illuminates when the input signal is clipping. Reduce input gain if this LED lights up frequently.
- LOW CUT: Activates a high-pass filter to remove unwanted low frequencies.
- XOVER FREQ (LOW/HIGH): Sets the crossover frequency between the low and high outputs for stereo 2-way mode, or low and mid outputs for mono 3-way mode.
- XOVER FREQ (MID/HIGH): Sets the crossover frequency between the mid and high outputs for mono 3-way mode.
- LOW OUTPUT LEVEL: Adjusts the output level for the low-frequency band.
- HIGH OUTPUT LEVEL: Adjusts the output level for the high-frequency band.
- MID OUTPUT LEVEL: Adjusts the output level for the mid-frequency band (mono 3-way mode only).
- MUTE BUTTONS: Silences the corresponding output for system tuning.
- PHASE INVERT: Inverts the phase of the corresponding output signal.
- MODE SWITCH: Selects between STEREO 2-WAY and MONO 3-WAY operation.
- SUBWOOFER FREQ: Sets the crossover frequency for the dedicated subwoofer output.
- SUBWOOFER GAIN: Adjusts the output level for the subwoofer.
- POWER SWITCH: Turns the unit on or off.

- AC INPUT: Standard IEC connector for the mains power cable.
- INPUT L/R: Balanced XLR inputs for the stereo audio signal.
- LOW OUTPUT L/R: Balanced XLR outputs for the low-frequency signal.
- MID OUTPUT L/R: Balanced XLR outputs for the mid-frequency signal (mono 3-way mode only).
- HIGH OUTPUT L/R: Balanced XLR outputs for the high-frequency signal.
- SUB OUT: Balanced XLR output for the mono subwoofer signal.
5. Setup and Connection
Proper setup is essential for optimal performance. Always ensure all audio equipment is powered off before making connections.
5.1. Stereo 2-Way Operation
This configuration is suitable for systems with main stereo speakers and an optional subwoofer.
- Connect the stereo output of your mixer or audio source to the INPUT L and INPUT R XLR connectors on the CX2310 rear panel.
- Set the MODE switch on the front panel to STEREO 2-WAY.
- Connect the LOW OUTPUT L/R to the inputs of your low-frequency amplifier (e.g., for woofers).
- Connect the HIGH OUTPUT L/R to the inputs of your high-frequency amplifier (e.g., for tweeters/mid-range).
- If using a subwoofer, connect the SUB OUT to the input of your subwoofer amplifier or active subwoofer.
- Connect the power cable to the AC INPUT and then to a suitable power outlet.
5.2. Mono 3-Way Operation
This configuration is ideal for a single, full-range speaker system divided into low, mid, and high frequency bands.
- Connect a mono audio source to the INPUT L XLR connector. (The CX2310 will sum the inputs for mono 3-way operation if both are connected, or use only the left input if only one is present).
- Set the MODE switch on the front panel to MONO 3-WAY.
- Connect the LOW OUTPUT L to the input of your low-frequency amplifier.
- Connect the MID OUTPUT L to the input of your mid-frequency amplifier.
- Connect the HIGH OUTPUT L to the input of your high-frequency amplifier.
- If using a subwoofer, connect the SUB OUT to the input of your subwoofer amplifier or active subwoofer.
- Connect the power cable to the AC INPUT and then to a suitable power outlet.
6. Operating Instructions
Once connected, follow these steps to configure and operate your CX2310:
- Power On: Turn on all connected amplifiers and then the CX2310. When powering down, turn off the CX2310 first, then the amplifiers.
- Initial Settings: Set all INPUT GAIN and OUTPUT LEVEL controls to their center (0 dB) position. Set crossover frequencies to a starting point recommended by your speaker manufacturer, or a common value like 100 Hz for low/high and 2 kHz for mid/high.
- Input Level Adjustment: Play an audio signal through your system. Adjust the INPUT GAIN until the signal is strong but the CLIP LED only flashes occasionally on peaks.
- Crossover Frequency Adjustment: Carefully adjust the XOVER FREQ controls to achieve the desired frequency separation. Listen for smooth transitions between frequency bands.
- Output Level Adjustment: Use the individual OUTPUT LEVEL controls to balance the volume of each frequency band. The MUTE buttons can be used to isolate bands for easier adjustment.
- Subwoofer Integration: Adjust the SUBWOOFER FREQ and SUBWOOFER GAIN controls to blend the subwoofer output seamlessly with the main speakers.
- Phase Alignment: Experiment with the PHASE INVERT switches if you notice phase cancellation or an unnatural sound. This helps ensure all speakers are working in phase.
7. Maintenance
The Behringer CX2310 is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure its longevity:
- Cleaning: Disconnect the unit from power before cleaning. Use a soft, dry cloth to wipe the exterior. Avoid abrasive cleaners or solvents.
- Environment: Operate the unit in a clean, dry environment. Avoid excessive dust, humidity, and extreme temperatures.
- Ventilation: Ensure that the ventilation slots are not obstructed to prevent overheating.
- Storage: If storing the unit for an extended period, disconnect it from power and store it in a cool, dry place, preferably in its original packaging.
8. Troubleshooting
If you encounter issues with your CX2310, consult the following table before contacting support:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from any output. | Unit not powered on; incorrect connections; input gain too low; all outputs muted. | Check power cable and switch; verify all XLR connections; increase input gain; ensure mute buttons are disengaged. |
| No sound from a specific output. | Output muted; output level too low; incorrect mode selection. | Check the specific output's mute button; increase output level; verify correct 2-way/3-way mode. |
| Distorted sound. | Input signal too high (clipping); output signal too high. | Reduce input gain if CLIP LED is constantly lit; reduce output levels. |
| Hum or noise. | Ground loop; unbalanced cables; faulty cables. | Ensure all equipment is properly grounded; use balanced XLR cables; test with different cables. |
| Subwoofer not working. | Subwoofer output muted; subwoofer gain too low; incorrect frequency setting. | Check subwoofer mute button; increase subwoofer gain; adjust subwoofer frequency control. |
