4061-OC-C-B00 d:screet™ CORE 4061 微型电容话筒,全指向,高声压,黑色 d:screet™ CORE 4061 低灵敏度全指向话筒，具有非常干净、细节丰富及自然的音质。由于初是为在剧院、电视及对乐器进行近距离拾音等应用场合与无线系统一起使用而设计的，因此 d:screet™ CORE 4061低灵敏度微型全指向话筒非常不易被察觉。由于其小巧的尺寸，它展现出非常精确的全指向覆盖图形，从而无需直接对准音源就能获得高品质的拾音。 这一话筒与d:screet™ CORE 4061 高灵敏度微型全指向话筒在声学上是完全一样的，但它的灵敏度经过调整以便与市场上一些更为灵敏的发射机相匹配。 话筒可以承受144 dB削波前峰值声压级，使得话筒可用于小军鼓、吉它/贝司音箱或其它高声压级的音源。d:screet™ CORE 4061 有四种颜 色可选:黑色、棕色、肉色和白色。 技术参数 Directional pattern | Omnidirectional | Principle of operation | Pressure | Cartridge type | Pre-polarized condenser | Frequency range | 20 Hz - 20 kHz | Frequency range, ±2 dB | Soft boost grid | Sensitivity, nominal, ±3 dB at 1 kHz | 6 mV/Pa; -44 dB re. 1 V/Pa | Equivalent noise level, A-weighted | Typ. 26 dB(A) re. 20 μPa (max. 28 dB(A)) | Equivalent noise level, ITU-R BS.468-4 | Typ. 38 dB (max. 40 dB) | S/N ratio (A-weighted), re. 1 kHz at 1 Pa (94 dB SPL) | Typ. 68 dB(A) | Total harmonic distortion (THD) – Legacy | < 1% THD up to 123 dB SPL peak; < 1% THD up to 120 dB SPL RMS sine | Total harmonic distortion (THD) – CORE | < 1% THD up to 137 dB SPL peak | Dynamic range – Legacy | Typ. 97 dB | Dynamic range – CORE | Typ. 111 dB | Max.
