The VQ1800D features a built-in stereo crossover, allowing you to connect full-range loudspeakers directly to its outputs.

1. توصيل الطاقة: Connect the supplied power cable to the AC inlet on the rear panel of the subwoofer and then to a suitable mains power outlet.
2. مدخل الصوت: Connect your audio source (e.g., mixer, audio interface) to the XLR input connectors (INPUT 1 or INPUT 2) on the rear panel.
3. 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.

5.2. Adjusting Volume and Crossover

The VQ1800D features controls for fine-tuning its performance:

• التحكم في المستوى: 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.
• تبديل المرحلة: Inverts the phase of the subwoofer's output. Experiment with this setting to achieve optimal bass alignment with your main speakers.
• مؤشر LED: 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.

If you encounter issues with your VQ1800D subwoofer, refer to the following common troubleshooting steps:

• لا يوجد طاقة: Ensure the power cable is securely connected to both the subwoofer and the power outlet. Check the power switch position and the mains fuse.
• لا يوجد صوت: 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.
• صوت جهير ضعيف: 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.
