5.1 Ntinye anụ ahụ
The X-Sub 118SA is designed for floor standing placement. Due to its omnidirectional dispersion, it can be positioned in various locations within a room or stage. For optimal bass response, consider placing the subwoofer near a wall or in a corner, which can acoustically reinforce low frequencies. Ensure the unit is stable and has sufficient space for ventilation.
5.2 Njikọ
The rear panel of the X-Sub 118SA provides all necessary connections and controls. Refer to the diagram below for a visual guide:
Figure 5.1: FBT X-Sub 118SA Rear Control Panel. This diagram illustrates the input/output connections, voltage selector, power switch, and DSP controls on the rear of the subwoofer.
- Ntinye (IN): Connect your audio source (e.g., mixer, preamplifier) to the XLR/Jack combo inputs. The unit supports stereo input.
- Link (LINK): These XLR outputs allow you to daisy-chain the audio signal to other subwoofers or full-range speakers.
- HP Filter Out (HP FILT OUT): These XLR outputs provide a high-pass filtered signal, ideal for connecting to full-range loudspeakers (e.g., FBT X-LITE or X-PRO series) to ensure proper crossover and system integration.
5.3 Power Connection and Voltage Nhọrọ
Tupu ijikọ eriri ọkụ eletrik, hụ na vol ahụ dị.tage selector mgba ọkụ na azụ panel ka atọrọ na nke ziri ezi voltage for your region (100-120V~ or 220-240V~). Incorrect voltage selection can damage the unit. Once the voltage is set, connect the supplied power cord to the IEC inlet and then to a grounded AC power outlet.
6. .rụ ọrụ
6.1 Gbanyụọ/ gbanyụọ
After all connections are made, flip the 'ON' switch on the rear panel to power on the subwoofer. The power indicator LED will illuminate. To power off, flip the switch back to 'OFF'.
6.2 Level Control (LEV)
The 'LEV' knob controls the overall output volume of the subwoofer. Start with the level set to minimum and gradually increase it to achieve the desired bass balance with your main speakers.
6.3 Ntọala DSP
The X-Sub 118SA features 4 DSP presets to optimize its performance for different applications and acoustic environments. Use the 'PRESET' button to cycle through the available options:
- Preset 1 (ORIGINAL 80Hz): Standard response with an 80Hz low-pass filter.
- Preset 2 (ORIGINAL 120Hz): Standard response with a 120Hz low-pass filter.
- Preset 3 (PUNCH 80Hz): Enhanced punchy bass response with an 80Hz low-pass filter.
- Preset 4 (PUNCH 120Hz): Enhanced punchy bass response with a 120Hz low-pass filter.
Select the preset that best suits your audio content and desired sound profile.
6.4 Phase Reversal (PHASE 0°/180°)
The 'PHASE' switch allows you to invert the phase of the subwoofer's output by 180 degrees. This is crucial for achieving optimal acoustic alignment with your main loudspeakers. Experiment with both 0° and 180° settings to find the position that yields the strongest and most coherent bass response in your listening environment.
6.5 PRT/LMT LED Indicators
The 'PRT/LMT' LED indicates the status of the protection and limiter circuits:
- Akwụkwọ ndụ akwụkwọ ndụ: Arụ ọrụ nkịtị.
- Red (briefly): Limiter is active, indicating that the input signal is approaching or exceeding the maximum safe level. This prevents distortion and protects the speaker.
- Uhie (siri ike): Protection circuit is active, indicating a potential fault or overheating. Reduce the input level or power off the unit and allow it to cool down.
7. Nlekọta
Proper maintenance ensures the longevity and optimal performance of your FBT X-Sub 118SA.
- Nhicha: Use a soft, dry cloth to clean the exterior of the subwoofer. Do not use abrasive cleaners, solvents, or excessive moisture.
- Nchekwa: When not in use for extended periods, store the subwoofer in a dry, temperate environment, away from direct sunlight and extreme temperatures.
- Nyocha: Periodically check the power cord and audio cables for any signs of damage.
