• Ihe omume dị ndụ: Excellent for touring, bands, and orchestras.
• Acoustics ime ụlọ: Subwoofer placement significantly impacts bass response. Experiment with different positions within the room to find the best sound. Corner placement often provides maximum bass output, but can sometimes lead to muddiness.
• Nkwụsi ike: Ensure the subwoofer is placed on a stable, level surface to prevent vibrations and movement during operation.
• Igwe ikuku: Allow adequate space around the unit for proper ventilation to prevent overheating.

5.2 Njikọ

Follow these steps to connect your FBT XSUB115SA:

1. Njikọ ike: Before connecting the power cord, ensure the Voltage Selector on the rear panel matches your local power supply (100-120V or 220-240V). Connect the supplied power cord to the AC Power Input on the subwoofer and then to a grounded electrical outlet.
2. Ntinye odiyo: Connect your audio source (e.g., mixer, audio interface) to the XLR/jack IN connectors on the rear panel. Use balanced XLR cables for best performance.
3. Output to Satellite Speakers (Optional): If using satellite speakers (e.g., FBT X-LITE or X-PRO series), connect the HP Filter Outputs (HP FILT OUT) of the subwoofer to the inputs of your satellite speakers. This sends a high-pass filtered signal to the satellites, allowing the subwoofer to handle the low frequencies.
4. Ịcha Daisy (Nhọrọ): To connect multiple subwoofers, use the Link Outputs (LINK) to send the full-range signal to the input of another subwoofer.

Always ensure all connections are secure before powering on the unit.

6.1 Gbanyụọ/ gbanyụọ

1. Ensure all connections are made and the Level control is set to minimum.
2. Flip the Power switch to the "ON" position. The power indicator LED will illuminate.
3. To power off, set the Level control to minimum and then flip the Power switch to the "OFF" position.

6.2 na-agbanwe olu

Use the Level control knob on the rear panel to adjust the output volume of the subwoofer. Start with a low setting and gradually increase it to the desired level, ensuring the PRT/LMT indicator does not frequently illuminate, which would indicate signal clipping.

6.3 Ntọala DSP

The FBT XSUB115SA features a digital signal processor with 4 presets, allowing extensive customization of low frequencies. Use the Preset switch to cycle through the available options. Each preset may offer different frequency responses or crossover points optimized for various applications or speaker combinations.

Refer to the specific preset descriptions in the full technical manual (if available) for detailed information on each preset's characteristics.

6.4 Phase Reversal

The Phase 0°/180° switch allows you to reverse the phase of the subwoofer's output. This is crucial for proper integration with full-range speakers. In some setups, reversing the phase can improve the overall bass response and clarity by ensuring the subwoofer's sound waves are in phase with the main speakers at the listening position. Experiment with both settings to determine which provides the most coherent and impactful bass.
