2. ການປ້ອນຂໍ້ມູນສຽງ: 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:

• ການຄວບຄຸມລະດັບ: 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.
• ສະວິດໄລຍະ: Inverts the phase of the subwoofer's output. Experiment with this setting to achieve optimal bass alignment with your main speakers.
• LIMIT 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.

• 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 ກໍາລັງຖືກຂັບເຄື່ອນເກີນໄປ.
• Bass ອ່ອນ: 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.
