The first Neumann microphone with a dynamic capsule. Functionally optimized design
specifically for the broadcast field, featuring integrated pop protection, suppression of
structure-borne noise and a hypercardioid directional characteristic. 
Emotion conveyed with technical perfection. This is the ideal which the Neumann
microphones in the Broadcast Line have been designed to fulfill. The fine-tuning to the
requirements of professional broadcast studios and the individual, functionally optimized
design* ensure that these are microphones of character.
The BCM 705 is Neumann?s first dynamic microphone. The housing and headgrille are
identical to those of the BCM 104; only the green logo indicates that this is something new
from Neumann. The principle of reduction to the essentials can be seen in the dynamic
capsule with a hypercardioid directional characteristic, specifically designed for speech
reproduction at close range. Multi-level isolation from structure-borne noise ensures operation
free of interference, even in a lively studio environment.
Mechanical Features
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. Iin 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 features
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.

The UNlDYNE? III Model 545SD is a dual-impedance, unidrectional, dynamic microphone. Shipped connected for low-impedance operation, it features a silent magnetic reed on/off switch.

The 545SD is a favorite for instrument pickup and recording, and can be used on lecterns for public address systems such as those used in political conventions and legislatures, convention halls, hotels, public auditoriums, stadiums, schools, and churches.

• Exceptionally uniform cardioid pattern minimizes feedback in PA applications
• Selectable dual-impedance operation
• Silent magnetic reed on/off switch with lock-on option
• Cardioid dynamic
• Frequency response: 50 to 15,000 Hz.
