Neumann BCM 705 Dynamic Studio Mic W/Hypercardioid Polar Pattern

BCM 705 – Overview

• Features:

  • Mechanical
  • The microphone headgrille twists off easily for quick cleaning. Neumann offers optional, color-coded headgrilles so that, for reasons of hygiene, each announcer can use his or her individual headgrille. In front of the capsule, mounted on a frame holder, a fine gauze serves as a built-in popscreen.
  • The microphones of the Broadcast Line have an elastic mount against structure-borne noise, that is compatible with standard broadcast-segment microphone arms.
    Acoustic
  • The frequency response has a light treble boost, in the region from 2 kHz to 9 kHz, aiding the speech intelligibility. The bass frequency response is designed to compensate for the overemphasis of the bass caused by the proximity effect.
    The integrated Pop Screen
  • A pop screen not only prevents the occurrence of plosive pop noises in vocal recordings, but also efficiently prevents unwanted particles, from respiratory moisture, nicotine, to food remnants, from settling on the diaphragm. The pop screen can be removed for cleaning without the use of tools.
    Mounting
  • The preferred mode of operation is to suspend the BCM 104 or BCM 705 from a standard studio boom arm.
  • A thread adapter to fit different connector threads is included. In order to provide protection from structure-borne noise, both the capsule and the microphone in its mount are elastically suspended.
  • The optional SG 5 swivel mount allows additional angling of the microphone by +/-90 degrees.
    Other
