1. The distance between the actor and the microphone The distance between the performer and the microphone can be categorized into three main types: close, medium, and long range. Each has its own advantages and is suited for different vocal styles and performance scenarios. 1) Close-range pickup: This involves placing the microphone 1–5 cm from the mouth, ideal for low-pitched voices and pop singers. It's especially effective for bass-heavy speakers or hosts who need a strong sense of intimacy and realism. Since the sound is captured directly with minimal ambient interference, it results in a clean, detailed, and immersive audio experience. Equalization (EQ) recommendations for speech: - 100Hz–200Hz: Reduce by 3–6dB to counteract the proximity effect. - 200Hz–300Hz: Boost by 3–6dB to enhance the natural warmth of speech. - 1–2kHz: Add 3–6dB to increase clarity and brightness. - Above 8kHz: Reduce by 3dB to minimize high-frequency noise, as speech has fewer high harmonics than singing. Without effects, this setup gives the host a realistic and personal sound. 2) Medium-range pickup: The microphone is placed 5–10 cm from the sound source, commonly used for national singing or more expressive performances. The distance allows for a balanced tone that feels relaxed and lively, contributing to a more dynamic atmosphere in a karaoke setting. National songs require clear enunciation, proper resonance, and a bright, pure tone that reflects cultural authenticity. EQ settings for this range: - 100Hz: No boost or cut, as there’s no proximity effect. - 256Hz–440Hz: Increase by 3–6dB to add body and richness. - 1–3kHz: Boost by 3dB to improve clarity and presence. - 10kHz: Add 3dB to enhance the expressiveness and resolution of the voice. 3) Long-range pickup: This involves a distance of 10–20 cm, typically used for Bel Canto singing. Bel Canto requires trained vocal technique, resulting in a rich harmonic structure and strong overtones. The microphone must capture a wide frequency range to preserve the fullness of the sound. To ensure good frequency response: - 1LF (low frequency): Boost by 3–6dB to add depth. - 256Hz–315Hz: Increase by 3–6dB for warmth and fullness. - 1–2kHz: Boost by 3–6dB to maintain clarity. - 10kHz: Add 3–6dB to enhance detail and projection. 2. Microphone angle (1) Close-range pickup (pop singing): The microphone should be angled at 15°–30° from the mouth to avoid low-frequency rumble caused by air movement. (2) Medium-range pickup (national and Bel Canto): A 15° angle is usually sufficient when the distance is 5–20 cm. (3) Long-range pickup: When capturing multiple sound sources like vocals and an orchestra, the microphone should be aligned directly with the sound source (0° angle) to ensure optimal pickup and balance.
