설정
1. 언박싱 및 검사
조심스럽게 amplifier from its packaging. Inspect the unit for any signs of damage. Ensure all components are present.
2. 전원 연결
The UB-30 can be powered by either AC mains or a 12V DC battery.
- AC Mains (220-240V): Connect the provided AC power cord to the AC power input on the rear panel and then to a suitable wall outlet.
- DC Battery (12V): For portable use, connect a 12V car battery to the DC input terminals on the rear panel. Ensure correct polarity: positive (+) to positive, negative (-) to negative.
주의: 항상 amplifier is switched OFF before connecting or disconnecting power sources.
3. 스피커 연결
Connect your speakers to the appropriate terminals on the rear panel. Match the speaker impedance to the amplifier's output impedance for optimal performance and to prevent damage.
- Connect the common (negative) terminal of your speaker(s) to the 코. 터미널에 amp리퍼.
- Connect the positive terminal of your speaker(s) to the 4Ω, 8Ω, 또는 16Ω terminal, matching your speaker's impedance.
- For 100V line speakers, connect to the 100V 터미널 및 코.. Ensure your speakers are compatible with 100V line systems.
중요한: Do not connect speakers to multiple impedance terminals simultaneously. Ensure all connections are secure.
4. Input Device Connection
- 마이크: 마이크를 연결하세요 마이크-1 그리고/또는 MIC-2/AUX 6.3mm input jacks on the front panel.
- 보조 장치: Connect audio sources like smartphones, CD players, or laptops to the MIC-2/AUX input jack using an appropriate cable.
작동 지침
1. 전원 켜기
- Ensure all volume controls (MIC-1, MIC-2/AUX) are set to their minimum position (fully counter-clockwise).
- 를 누르세요 힘 switch on the front panel to the 'ON' position. The power indicator light will illuminate.
2. 볼륨 조절
- For MIC-1, slowly turn the MIC-1 볼륨 조절 clockwise until the desired sound level is achieved.
- For MIC-2 or AUX input, slowly turn the MIC-2/AUX Volume Control clockwise until the desired sound level is achieved.
- Avoid setting the volume too high, which can cause distortion or damage to speakers.
3. 음색 조정
사용하세요 톤 컨트롤 knob to adjust the frequency response of the amplifier. Turning it towards 'CUT' will reduce higher frequencies (treble), while turning it towards 'FLAT' will provide a more balanced, full-range sound.
4. 전원 끄기
- Turn all volume controls to their minimum position.
- 를 누르세요 힘 switch to the 'OFF' position. The power indicator light will turn off.
유지
청소
겉면을 닦아주세요 amplifier with a soft, dry cloth. Do not use liquid cleaners or abrasive materials, as they may damage the finish or internal components.
Fuse Replacement (DC Fuse)
