CARDIOID CONDENSER INSTRUMENT MICROPHONE

- Unique side-address stick design maximizes placement options with

minimal obstructions.

- Uncompromising sound quality for overheads, percussion, acoustic

guitar, strings and other acoustic instruments.

- Integral 80 Hz HPF switch and 10 dB pad.

- Durable performance for professional applications.

- Cardioid polar pattern reduces pickup of sounds from the sides and

rear, improving isolation of desired sound source.

- Rugged, all-matal design and construction for years of trouble-free

use.

- Includes isolation clamp for shock protection, secure mounting and

easy positioning.

The ATM450 is intended for use in professional applications where

remote power is available. It required 11V to 52V DC phantom power,

which may be provided by a mixer or console, or by a separate, in-

line source such as the Audio-Technica AT8801 single-channel or

AT8506 four-channel phantom power supplies.

Output from the microphone’s XLRM-type connector is low

impedance (Lo-Z) balanced. The signal appears across Pins 2 and

3; Pin 1 is ground (shield). Output phase is “Pin 2 hot” - positive

acoustic pressure produces positive voltage at Pin 2.

To avoid phase cancellation and poor sound, all mic cables must be

wired consistently: Pin 1-to-Pin 1, etc.

An integral 80Hz hi-pass filter provides easy switching from a

flat frequency response to a low-end roll-off. The roll-off position

reduces the pickup of low-frequency ambient noise (such as trafc,

air-handling systems, etc.), room reverberation and mechanically

coupled vibrations.

The ATM450 is also equipped with a switchable 10 dB pad that

lowers the microphones’s sensitivity, thus providing higher SPL

capability for exible use with a wide range of performers and system

congurations.

The ATM450 includes an AT8471 isolation clamp to provide secure

mounting, versatile positioning and effective dampening of unwanted

mechanical noise.

Avoid leaving the microphone in the open sun or in areas where

temperatures exceed 40°C for extended periods. Extremely high

humidity should also be avoided.

心形指向性电容式乐器话筒

- 独有的棒型边侧录音设计，提供最大的收音面积及最小的阻

碍。

- 高稳定性的收音质量，合适于敲击乐器、原音结他、弦乐器

及其他演奏乐器等的作收音工作。

- 80Hz 10dB内置高通滤波器及衰减。

- 专业应用性的耐用表现。

- 心形指向性收音，能有效减低旁边及后方的杂声干扰。

- 全金属结构，坚固、耐用、可长期使用。

- 配有防震话筒夹，提供稳固的安装，及调校夹持位置。

ATM450 11V 52V应用于专业收音工作，需要提供至幻象供电，可

使用调音台上的幻象电源，也可以使用鐵三角的AT8801单通道或

AT8506四通道幻象电源供电器作独立供电。

话筒的卡农输出端为低阻抗平衡输出，话筒音频信号最终XLRM

以卡农公头的2号及3号针脚输出，而1号针脚则为地线(屏蔽)连

接。输出相位将以正相位电平设于 2号针脚上。

为避免出现相位相互抵消而失真的情况，所有话筒连接时，

接线必需以 1-1，2-2，3-3型式把针脚连接。

内置高通滤波电路，可轻易由平直的频率响应，开启为于 80 Hz

以下衰减的收音效果，应用高通滤波器可减低收音环境中低频噪

声(如外间汔车引擎声，空调系统的风声等)，房间中的回声及机

械性的震动声。

话筒并设有10dB衰减开关，在高声压环境收音时，减低话筒的灵

敏度，避免破声的失真现象出现。

ATM450 AT8471配套有防震话筒夹，提供稳固的安装，及可调校

夹持位置，能减低机械性的震动及噪声。

把话筒暴露于高温中可能导致输出电平逐渐及永久性减弱，应避

免将话筒留在日晒的地方或长时间置于温度超过 43°C的地方，而

极高湿度也应避免。
