4.2. සම්බන්ධතා
The VQ1800D features a built-in stereo crossover, allowing you to connect full-range loudspeakers directly to its outputs.
- බල සම්බන්ධතාවය: Connect the supplied power cable to the AC inlet on the rear panel of the subwoofer and then to a suitable mains power outlet.
- ශ්රව්ය ආදානය: Connect your audio source (e.g., mixer, audio interface) to the XLR input connectors (INPUT 1 or INPUT 2) on the rear panel.
- Audio Output (to Full-Range Speakers): If using the built-in stereo crossover, connect your full-range loudspeakers to the XLR output connectors (OUTPUT 1 or OUTPUT 2). These outputs provide a high-pass filtered signal to your main speakers, optimizing their performance.

- බල ගැන්වීමට පෙර සියලු සම්බන්ධතා ආරක්ෂිත බව සහතික කර ගන්න.
- Press the POWER switch on the rear panel to turn the subwoofer on. The power LED will illuminate.
- To power off, press the POWER switch again.
5.2. Adjusting Volume and Crossover
The VQ1800D features controls for fine-tuning its performance:
- LEVEL Control: Adjusts the overall output volume of the subwoofer. Start with a low setting and gradually increase to your desired level.
- BOOST Frequency: Allows you to select a specific frequency range (40 Hz to 90 Hz) to boost for enhanced bass impact.
- HIGH CUT Control: Sets the crossover frequency for the subwoofer (70 Hz to 150 Hz). This determines the upper frequency limit of the subwoofer's output and the lower frequency limit of the signal sent to your full-range speakers via the 'PASS THRU' outputs.
- PHASE ස්විචය: Inverts the phase of the subwoofer's output. Experiment with this setting to achieve optimal bass alignment with your main speakers.
- LED සීමා: Illuminates when the internal limiter is active, indicating that the signal is too high and clipping may occur. Reduce the input level or the LEVEL control if this LED is constantly lit.

6. නඩත්තු කිරීම
Regular maintenance ensures the longevity and optimal performance of your subwoofer:
- පිරිසිදු කිරීම: Use a soft, dry cloth to clean the exterior of the subwoofer. Do not use abrasive cleaners or solvents.
- වාතාශ්රය: Periodically check that the ventilation openings are free from dust and debris.
- ගබඩා: When not in use for extended periods, store the subwoofer in a dry, cool environment, protected from dust and extreme temperatures.
- පරීක්ෂාව: Regularly inspect the power cable and audio cables for any signs of damage. Replace damaged cables immediately.
7. දෝශ නිරාකරණය
If you encounter issues with your VQ1800D subwoofer, refer to the following common troubleshooting steps:
- බලය නැත: Ensure the power cable is securely connected to both the subwoofer and the power outlet. Check the power switch position and the mains fuse.
- ශබ්දයක් නැත: Verify that the audio source is active and connected correctly to the subwoofer's inputs. Check the LEVEL control setting. Ensure any connected full-range speakers are also powered on and receiving a signal from the subwoofer's outputs.
- Distorted Sound / LIMIT LED Constantly On: Reduce the input signal level from your audio source or lower the subwoofer's LEVEL control. The LIMIT LED indicates that the amplifier is being overdriven.
- දුර්වල බාස්: Check the PHASE switch setting. Experiment with both positions to find the optimal phase alignment with your main speakers. Ensure the HIGH CUT frequency is set appropriately for your system.
If the problem persists after attempting these steps, contact qualified service personnel.
