3. 설정
3.1 장치 전원 공급
The MX401 can be powered using the included DC power supply or two 9V batteries. Ensure the unit is switched OFF before connecting power.
- DC 전원 : Connect the included DC power supply to the 'VDC' input jack on the front panel. Plug the power supply into an appropriate AC outlet.
- 배터리 전원: Open the battery compartment on the side of the unit and insert two fresh 9V batteries, observing correct polarity. Close the compartment securely.
3.2 Connecting Microphones and Line Inputs
The MX401 features four XLR inputs, each capable of accepting either microphone or line-level signals.
- Connect your microphones or line-level devices to the XLR INPUTs (CH 1-4) on the rear panel.
- For each channel, use the 마이크 / 라인 switch to select the appropriate input level:
- 설정하다 마이크 for microphones.
- 설정하다 선 for line-level devices (e.g., keyboards, CD players).
- If using condenser microphones, activate 팬텀 파워 for the respective channel by pressing the PHANTOM POWER button. The LED will illuminate when active.
3.3 출력 연결
The MX401 provides balanced XLR outputs and a 3.5mm stereo output.
- Connect your main audio system (e.g., power amplifier, recording device) to the balanced XLR OUTPUTS (LEFT, RIGHT) 후면 패널에.
- For connecting to consumer-grade audio equipment or headphones, use the 3.5mm STEREO OUTPUT 전면 패널의 잭.
4. 사용 설명서
4.1 전원 켜기/끄기
모든 연결이 완료되면 스위치를 켜십시오. 전원 켜기-끄기 toggle on the front panel to the ON position. The 'pwr' LED will illuminate.
4.2 채널 제어
Each of the four input channels (CH 1-4) has independent controls:
- 수준: Adjusts the input gain for the respective channel. Start with this knob fully counter-clockwise and slowly increase it until the desired volume is achieved without clipping.
- PAN : Controls the stereo positioning of the channel's signal between the Left and Right outputs. Turn clockwise for more Right signal, counter-clockwise for more Left signal, and center for an even spread.
- 마이크/라인 스위치: Selects between microphone-level and line-level input sensitivity.
- PHANTOM POWER Button: Activates +48V phantom power for condenser microphones connected to that channel.
4.3 Output Level Control
The master output level is controlled by the 출력 레벨 knob on the front panel. Adjust this to set the overall volume of the mixed signal sent to the outputs.
4.4 Clip Indicator
그만큼 클립 LED on the front panel illuminates when the input or output signal is too high, indicating potential distortion. If the CLIP LED lights up, reduce the corresponding channel LEVEL or the master OUTPUT LEVEL until the LED no longer illuminates during peak signal levels.
5. 유지관리
To ensure the longevity and optimal performance of your Rolls MX401, follow these maintenance guidelines:
- 청소: 제품 외부를 닦을 때는 부드럽고 마른 천을 사용하십시오. 연마성 세제, 용제 또는 왁스는 마감재를 손상시킬 수 있으므로 사용하지 마십시오.
- 저장: 장기간 사용하지 않을 경우 믹서를 직사광선과 극한 온도 변화를 피해 서늘하고 건조한 곳에 보관하십시오.
- 배터리 교체: If using battery power, replace batteries when the 'pwr' LED dims or the unit ceases to function. Remove batteries if the unit will not be used for a long time to prevent leakage.
- 통풍: 과열을 방지하기 위해 장치 주변의 환기를 잘 하세요. 환기구를 막지 마세요.
6. 문제 해결
If you encounter issues with your MX401, refer to the following common troubleshooting steps:
- 전원 없음:
- Check if the DC power supply is securely connected and plugged into a working outlet.
- If using batteries, ensure they are fresh and inserted with correct polarity.
- Verify the POWER ON-OFF switch is in the ON position.
- 소리 없음:
- Confirm all input and output cables are securely connected.
- Check that the input device is powered on and sending a signal.
- Ensure channel LEVEL knobs and the master OUTPUT LEVEL knob are turned up.
- Verify the MIC/LINE switches are set correctly for your input devices.
- If using condenser microphones, ensure PHANTOM POWER is activated for the respective channels.
- Check the volume and input selection on your connected audio system.
- Distorted Sound / Clipping:
- If the CLIP LED illuminates, reduce the corresponding channel LEVEL or the master OUTPUT LEVEL until it no longer lights up.
- Ensure the MIC/LINE switches are correctly set. Using MIC setting for a line-level device can cause distortion.
- 윙윙거리는 소리 또는 소음:
- 모든 케이블이 양호한 상태이고 적절하게 차폐되어 있는지 확인하십시오.
- Try using balanced XLR cables for inputs and outputs to minimize noise.
- 오디오 케이블과 전원 케이블이 평행하게 설치되지 않도록 하십시오.
