3. 설정

3.1 헤드셋 착용

Gently place the headset over your ears, ensuring a comfortable and secure fit.
Adjust the boom arm to position the microphone capsule approximately 1-2 cm (0.4-0.8 inches) from the corner of your mouth. This placement optimizes sound capture and minimizes plosives and breath noise.
The headset can be worn on either the left or right ear. Adjust the boom arm's orientation as needed.

3.2 마이크 연결

The DPA 4088 CORE features a Microdot connector. This connector requires a compatible adapter for connection to most wireless transmitters or XLR inputs.
Carefully align the Microdot connector with the adapter's input. Push firmly until it clicks into place. Do not force the connection.
Ensure the adapter is securely connected to your wireless transmitter or audio interface.
Verify that phantom power (if using an XLR adapter) or the correct voltage from your wireless transmitter is supplied to the microphone.

4. 사용 설명서

4.1 Audio Level Setting

Before use, perform a sound check to set appropriate gain levels on your connected wireless transmitter or audio mixer.
Speak or sing into the microphone at your typical performance volume.
Adjust the input gain to achieve a strong signal without clipping or distortion. Aim for peak levels around -6 dB to -3 dB on your meter.

4.2 사용 팁

근접 효과: Due to its cardioid pattern, the microphone exhibits a slight proximity effect. Maintain consistent distance from the corner of your mouth for a balanced sound.
바람 소음: For outdoor use or in windy conditions, consider using a windscreen (sold separately) to minimize wind noise.
피드백 방지: 위치 stage monitors or loudspeakers to avoid pointing directly at the microphone capsule, especially in live sound environments, to prevent feedback.

5. 유지관리

5.1 청소

Regularly wipe the headset frame and boom arm with a soft, damp 옷감.
For the microphone capsule, use a dry, soft brush or a cotton swab to gently remove any dust or debris. Avoid using liquids directly on the capsule.
Ensure the microphone is completely dry before storage or next use.

5.2 보관

Store the microphone in its original packaging or a protective case when not in use.
마이크를 극한 온도, 높은 습도 또는 직사광선에 노출시키지 마십시오.
Do not coil the cable tightly, as this can cause damage over time.

5.3 취급

Handle the microphone and its connectors with care. Avoid dropping or subjecting it to strong impacts.
When disconnecting the Microdot, grasp the connector body, not the cable.

6. 문제 해결

문제	가능한 원인	해결책
사운드 출력이 없습니다	마이크가 제대로 연결되지 않았습니다. No phantom power (for XLR adapters). Incorrect gain settings on transmitter/mixer. 케이블이나 어댑터에 문제가 있습니다.	Ensure Microdot and adapter connections are secure. Activate phantom power on your mixer or ensure wireless transmitter is powered. Check and adjust gain levels. Test with a different cable or adapter if available.
왜곡되거나 불분명한 소리	입력 게인이 너무 높습니다(클리핑). Microphone capsule too close to mouth. 주변 소음.	Reduce input gain on transmitter/mixer. Adjust microphone position to 1-2 cm from corner of mouth. Ensure proper acoustic environment; use windscreen if necessary.
피드백(울부짖는 소리)	Microphone too close to loudspeakers/monitors. 과도한 이득.	Reposition microphone or loudspeakers. Reduce overall system gain or specific frequency bands causing feedback.
