新一代广播话筒

BCM 104 是一款专用于无线电广播、直播和播客的广播话筒,旨在以诺音曼的理想品质传递情感。它采用功能上经过优化的设计,集成防喷网和防震的大振膜电容话筒头,专为语音应用而开发。采用无变压器电路,可确保声音直接、无噪音。

Dealer Description

让世界倾听您的声音

广播、直播和播客是接触听众的最直接方式。正因如此,诺音曼决定了开发 BCM 系列产品,专门满足电台 DJ、播音员、新闻主播、脱口秀主持人、播客等用户的需求,他们通过讲述故事、营造良好氛围和分享最新信息等方式,陪伴我们度过美好时光。
BCM 104 专为精准传递情感而设计。其独特外形在功能上实现了优化,可与行业标准麦克风杆配合使用。由于采用了弹性减震架,BCM 104 可以很好地抑制结构噪声。网罩后面集成防喷网,可防止话筒头受到气爆和爆破音的影响。为提高卫生水平,可轻松拧下网罩,快速进行清洁。
BCM 104 的大振膜电容话筒头可捕捉声音的每一个细微差别,而不会出现音染或音损。BCM 104 的电路可确保本底噪声超低,仅为 7 dB-A,并且能承受高达 138 dB 的巨大声压级而不失真。其平衡输出采用无变压器设计,可确保将嗡嗡声干扰降至最低,并且对电脑屏幕等外来信号具有很高的共模抑制能力。次声滤波器可抑制低于 20 Hz 的频率。对于近距离语音操作,可选择 100 Hz 低切,以补偿近讲效应。第二个开关可激活 -14 dB 的预衰减,以降低 BCM 104 的输出声压级,供设计用于动圈话筒(灵敏度通常比电容话筒低得多)的设备使用。两个开关都隐藏在话筒内,因为低切和预衰减选项通常只在设置时选择一次。
 

专为人声设计

BCM 104 采用固定心形模式,具有出色的后向声音抑制能力。其频率响应高度线性,在 4 kHz 附近有轻微的临场感提升,在 10 kHz 以上有轻微的高音提升,从而提高了语音清晰度。BCM 104 具有出色的瞬态响应,能够以令人惊叹的细腻程度捕捉人声的每一个细微差别。由于 BCM 104 的频率响应范围宽,因此除了语音应用外,还可用于拾取演唱和各种乐器的声音。

评价

"... since the quality of the BCM 104 is optimal for broadcast speaking applications. This applies not only to the sound characteristics, but also to the overall handling features, with the replaceable headgrille, pop protection and hidden switches for the preattenuation and high-pass filter."
Production Partner, September 2003

"In addition to looking the part of a 21st-century mic, the BCM´s impressive specs and sound should please any discerning audio pro."
MIX Magazine, August 2004

"There´s no doubt that the Neumann BCM 104 made a big impression - as you would expect from a very well engineered package - the built-in mount is a really great idea - and the sound is very, very good."
Audio Media, March 2004
