Sambungan:

• Input (XLR): Balanced XLR inputs for Channel 1 and Channel 2, receiving the full-range audio signal from your mixer or source.
• Low Out (XLR): Balanced XLR outputs for low-frequency signals, typically connected to subwoofer amplifsters.
• Mid Out (XLR): Balanced XLR outputs for mid-range frequency signals (available in 3-way and 4-way mono modes).
• High Out (XLR): Balanced XLR outputs for high-frequency signals, typically connected to full-range speaker amplifsters.
• Sub Out (XLR): Dedicated balanced XLR output for summed subwoofer signals.
• Input AC: Standard IEC power connector for connecting the unit to mains power.

4. Setup Guide

Proper setup of your CX3400 is crucial for optimal audio performance. This section outlines the steps for connecting your crossover in a typical 2-way stereo configuration.

4.1. Basic 2-Way Stereo Setup:

1. Sambungkeun Sumber Audio: Connect the main outputs of your mixer or audio source to the INPUTs of Channel 1 and Channel 2 on the CX3400 using XLR cables.
2. Connect Low-Frequency Amppanguat: Connect the LOW OUTs of Channel 1 and Channel 2 on the CX3400 to the inputs of your amplifier(s) driving your subwoofers or low-frequency speakers.
3. Connect High-Frequency Amppanguat: Connect the HIGH OUTs of Channel 1 and Channel 2 on the CX3400 to the inputs of your amplifier(s) driving your full-range or high-frequency speakers.
4. Daya Hurung: Ensure all connections are secure. Power on your mixer, then the CX3400, and finally your amplifsters.

4.2. Mono 3-Way/4-Way Setup:

For mono 3-way or 4-way operation, press the MODE switch to 'MONO'. In this mode, the inputs are summed, and the outputs are reconfigured to provide separate low, mid, and high-frequency signals, plus an additional subwoofer output if selected. Refer to the rear panel labels for specific output assignments in mono mode.

5. Parentah Operasi

Once your CX3400 is connected, fine-tuning the settings will optimize your sound system's performance.

5.1. Setting Crossover Frequencies:

1. Setélan Awal: Start with all GAIN knobs at 0dB and crossover frequency knobs at a neutral position.
2. Adjust Low/High Crossover: For 2-way operation, use the LOW/HIGH X-OVER FREQ knob to set the division point between your low-frequency speakers (subwoofers) and high-frequency speakers (full-range). A common starting point is around 80-120 Hz for subwoofers.
3. Adjust Mid/High Crossover (3-Way/4-Way): In 3-way or 4-way mono modes, additional crossover frequency knobs will be active to separate mid-range and high-frequency signals.
4. Use X-Over Freq Switch: If you need to adjust frequencies outside the standard range, use the x1/x10 switch to multiply the knob's range.

5.2. Gain and Level Adjustment:

1. Keuntungan Input: Adjust the INPUT GAIN for each channel to match the output level of your mixer. Avoid clipping (indicated by the CLIP LED).
2. Output Gains: Adjust the LOW OUTPUT, MID OUTPUT, and HIGH OUTPUT GAIN knobs to balance the volume levels of your different speaker components.
3. Keuntungan Subwoofer: Use the SUBWOOFER GAIN knob to control the overall level of the subwoofer output.

5.3. Limiter and Phase Control:

• Wates: Engage the LIMITER switches on each output to prevent signal peaks from distorting your speakers.
• Phase Reverse: Use the PHASE REVERSE switches if you encounter phase cancellation issues between speakers, which can result in a thin or weak sound.
• Saringan Subsonik: Activate the 25 Hz SUBSONIC FILTER to remove extremely low, inaudible frequencies that can waste amplifier power and potentially damage subwoofers.

6. Pangropéa

To ensure the longevity and reliable performance of your Behringer CX3400, follow these maintenance guidelines:

• beberesih: Rutin usap unit nganggo kaén anu lembut sareng garing. Ulah make cleaners abrasive atawa pangleyur.
• Ventilasi: Pastikeun aliran hawa di sakuriling unit cekap. Ulah ngahalangan liang ventilasi.

7. Cara ngungkulan

If you encounter issues with your CX3400, refer to the following troubleshooting tips:

• Henteu aya sora:
  • Check all power connections and ensure the unit is turned on.
  • Verify all audio cables are correctly connected to inputs and outputs.
  • Ensure input and output gain knobs are not set to minimum.
  • Check the MODE switch setting (Stereo/Mono) matches your setup.
• Sora distort:
  • Reduce input or output gain levels to prevent clipping (if CLIP LEDs are active).
  • Ensure the correct crossover frequencies are set for your speakers.
  • Check for damaged cables or faulty connections.
• Weak Bass/Lack of Low End:
  • Check the LOW OUT gain level.
  • Verify the crossover frequency for low-frequency speakers is set appropriately.
  • Ensure the 25 Hz subsonic filter is not inadvertently engaged if you require frequencies below this point.
  • Check phase settings using the PHASE REVERSE switches.
