Flexible Microphone Cables
Belden® microphone cable is used for
connecting low level microphones or
musical instruments.
　

Key properties of microphone (MIC) cable
are ruggedness, flexibility, flex life and
interference immunity. MIC cable
constructions utilize either 1-, 2-, 3- or
4-conductor configurations. Cable selection
depends on whether the MIC or instrument
is of a high- or low-impedance design.
High-impedance MICs require unbalanced
　

single conductor (coaxial) cables while
low-impedance MICs utilize balanced 2-, 3-,
or 4-conductor (quad) designs. Quad MIC
cables are connected by attaching the two
white conductors to one pin and two blue
conductors to the other pin in a
balanced-line XLR type connector.
　

Besides the common-mode rejection of a
standard balanced line, this gives
common-mode rejection at each pin,
greatly reducing noise and interference.

YJ57087 / YJ57088- 百通 公司的高性价比，高柔韧度，低阻
抗，高强韧度的四根导体星绞型麦 克风线缆

高柔韧度麦克风线缆

百通麦克风线缆适用于连接低电平麦克
风或者乐器。
　

麦克风线缆主要的特性是坚固性、弯曲
寿命及抗干扰性能。麦克风线缆的构造
使用或者1-，2-，3-或者4根导体配
置。线缆选择要根据麦克风或者乐器是
高或者低阻抗。高阻抗麦克风要求非平
衡单根导体（也就是同轴）线缆，而低
阻抗麦克风使用平衡的2、3或者4根导
体（Quad）设计。四根导体的线缆与接
头端接时，两根白色绝缘的导体与一个
接线柱连接，剩下的两根蓝色绝缘的导
体跟另外一个接线柱连接形成平衡线对
连接平衡输出型（XLR）接头。
　

除了标准平衡线对的共模抑制特性以
外，这种结构能在每个接线柱上形成共
模抑制，从而极大地降低了噪音与干
扰。
