1. Produktua amaitu daview

The Behringer Super-X Pro CX3400 is a high-precision stereo 2-way/3-way/mono 4-way crossover designed for professional audio applications. It features advanced Linkwitz-Riley filters, individual limiters, phase reverse switches, and a subsonic filter to optimize speaker performance and protect your system.

Ezaugarri nagusiak:

• 24 dB/octave, state-variable Linkwitz-Riley filters for precise frequency separation.
• Absolutely flat summed amplitude response, zero phase difference.
• Individual limiter and phase reverse switch per output.
• Switchable 25 Hz subsonic filter per input for low-frequency driver protection.
• Switchable equalization for constant directivity horns.

2. Aurrealdeko panelaren kontrolak

The front panel of the CX3400 provides intuitive controls for managing your audio signals. It features two main channels and a dedicated subwoofer section, allowing for flexible configuration.

Kontrolak:

• Switch potentziala: Unitatea pizten edo itzaltzen du.
• Irabazi botoiak: Adjust the input and output levels for each channel and the subwoofer.
• Low Cut (40Hz) Switch: Activates a 25 Hz subsonic filter to protect low-frequency drivers.
• Crossover Frequency Knobs: Set the frequency points where the audio signal is divided between different speaker ranges (e.g., low/high, low/mid, mid/high).
• X-Over Freq Switch (x1/x10): Multiplies the selected crossover frequency by 10 for extended range.
• Mode Switch (Stereo/Mono, 2-Way/3-Way): Selects between stereo 2-way, stereo 3-way, or mono 4-way operation.
• Phase Invert Switches: Reverses the phase of individual outputs to correct for acoustic phase issues.
• Limiter Switches: Activates the built-in limiters to prevent signal clipping and speaker damage.

3. Atzeko panelaren konexioak

The rear panel provides all necessary audio input and output connections, primarily using XLR connectors for balanced signal transmission.

Konexioak:

• 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 ampigogailuak.
• 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 ampigogailuak.
• Sub Out (XLR): Dedicated balanced XLR output for summed subwoofer signals.
• AC sarrera: Standard IEC power connector for connecting the unit to mains power.

4. Konfigurazio gida

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. Konektatu audio iturria: 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 Ampbiziagoa: 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 Ampbiziagoa: 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. Piztu: Ensure all connections are secure. Power on your mixer, then the CX3400, and finally your ampigogailuak.

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. Funtzionamendu-argibideak

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

5.1. Setting Crossover Frequencies:

1. Hasierako ezarpenak: 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. Sarrerako irabazia: 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. Subwoofer irabazia: Use the SUBWOOFER GAIN knob to control the overall level of the subwoofer output.

5.3. Limiter and Phase Control:

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

6. Mantentzea

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

• Garbiketa: Regularly wipe the unit with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
• Aireztapena: Ziurtatu aireztapen-fluxu egokia unitatearen inguruan. Ez blokeatu aireztapen-irekidurak.
• Biltegiratzea: Gorde unitatea leku fresko eta lehor batean, eguzki-argitik eta muturreko tenperaturetatik babestuta.
• Kableen ikuskapena: Periodically check all audio and power cables for damage or wear. Replace any faulty cables immediately.

7. Arazoak

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

• Soinurik ez:
  • 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.
• Soinu distortsionatua:
  • 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.
