Hypercardioid | The Beta 87 microphone has consistently been a top choice of performers and audio technicians around the world due to its superb accuracy and detail, and rich vocal production. This long-standing favorite now features a new design and has been renamed the Beta 87A TM.
In response to user requests, Shure has redesigned this microphone by just slightly thickening the handle for a more comfortable feel when hand-held. In addition, the Beta 87A now includes the A25D break-resistant swivel adapter.
The Shure Model Beta 87A is a premium quality supercardioid hand-held electret condenser vocal microphone with exceptionally smooth frequency response and high sound pressure level (SPL) capability. Used for professional sound reinforcement, broadcasting, and studio recording applications, the Beta 87A combines superb performance with the ruggedness needed for touring and field production.
The Beta 87A features a controlled low-frequency roll-off that compensates for proximity effect and prevents the "boomy" sound often associated with close pick-up. The characteristic Shure presence rise brightens the upper midrange. The tight supercardioid pattern, with null points at approximately 125 degrees, provides maximum isolation from other vocalists or instruments while offering minimal off-axis coloration. The Beta 87A operates on phantom power.
- Smooth, tailored frequency response provides detail, accuracy, and warmth for vocals
- Extremely accurate supercardioid pattern at all frequencies provides the highest gain-before-feedback
- Three-stage pop filter minimizes breath pop and noise
- Break-resistant stand adapter
- Frequency response: 50 to 20,000 Hz

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.
