Audio Technica AT875R (超窄指向性電容咪高峰)

AT875R提供高靈敏度的收音效能，可確保能接收到最大的音源。而在某些情況下，為避免發生超負載輸入而出現破聲情況，需要在咪高峰和前置放大器之間加入AT8202等的電平衰減器。

咪高峰符合RoHS規格，在構造上不含有歐盟禁用的危害性物質。

AT875R咪高峰需使用11V至52V幻象供電工作。

咪高峰的XLRM卡農輸出端為低阻抗平衡輸出，咪高峰音頻信號最終以卡農公頭的2號及3號針腳輸出，而1號針腳則為地線(遮罩)連接。輸出相位將以正相位電平設於2號針腳上。

The high sensitivity of the AT875R assures useful output and an excellent match to most input sources. In some cases, however, an attenuator such as the Audio-Technica AT8202 may be required between the microphone and preamplifier to avoid overloading sensitive input stages.

The microphone is RoHS compliant–free from all substances specified in the EU directive on hazardous substances.

The AT875R requires 11V to 52V DC phantom power for operation.

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.
