5. 설정
5.1 배치 및 장착
The FBT J 8A can be used as a floor monitor, mounted on a speaker stand, or permanently installed using its M6 anchoring points. Ensure the monitor is placed on a stable, level surface or securely mounted to prevent accidental falls.
- For floor use, position the monitor to direct sound towards the desired listening area.
- For stand mounting, use a compatible speaker stand with a standard pole mount.
- For permanent installation, utilize the two M6 anchoring points. Consult a qualified installer for secure wall or ceiling mounting.
5.2 연결
Before making any connections, ensure the monitor's power switch is in the OFF position and the power cord is disconnected from the mains supply.
- 오디오 입력: Connect your audio source (mixer, instrument, microphone) to the XLR/Jack combo input on the rear panel.
- 링크 출력: If connecting multiple monitors, use the XLR link output to send the audio signal to another active speaker.
- 전원 연결: Connect the supplied power cord to the AC inlet on the rear panel, then plug the other end into a suitable grounded AC power outlet (220-230V~ 50/60Hz).
Refer to Figure 2 for a visual guide to the rear panel connections.
6. 사용 설명서
6.1 전원 켜기/끄기
- Ensure all audio connections are made and the Level control is set to minimum.
- Flip the main power switch on the rear panel to the ON position. The power indicator LED will illuminate.
- To power off, set the Level control to minimum, then flip the power switch to OFF.
6.2 Input Level and Mic/Line Switch
- 마이크/라인 스위치: Select the appropriate input sensitivity. Use "MIC" for microphones and "LINE" for line-level sources (mixers, instruments).
- 레벨 제어: Adjust the overall volume of the monitor. Start with the control at minimum and gradually increase to the desired listening level.
- The PRT/LMT (Protection/Limit) LED indicates when the internal limiter is active, preventing distortion and protecting the speaker. If this LED flashes frequently, reduce the input level.
6.3개의 DSP 프리셋
The FBT J 8A features a Digital Signal Processor (DSP) with two selectable presets to optimize the sound for different applications:
- 원래의: Provides a flat, neutral frequency response suitable for general-purpose sound reinforcement.
- 후원: Enhances the low-frequency response, ideal for applications requiring more bass presence.
Select the desired preset using the dedicated switch on the rear panel.
6.4 Hi-Pass Filter
The Hi-Pass filter button activates a high-pass filter, which cuts low frequencies from the monitor's output. This is particularly useful when the J 8A is used in conjunction with a subwoofer, allowing the subwoofer to handle the lower frequencies and improving overall system clarity and efficiency.
