- Tailored for Vocals & Speech
- Cardioid Polar Pattern
- Shock-Mounted Dynamic Cartridge
- 50 Hz to 15 kHz Frequency Response
The Shure 55SH Series II is a Unidyne cardioid dynamic microphone boasting a classic look and vocal-tailored sound for recording sessions, live stage applications, and on-camera use. The dynamic cartridge is shock-mounted to impede handling noise and vibrations transferred through your mic stand. The implementation of a cardioid polar pattern minimizes pickup of off-axis noise and ambience, yielding higher gain before feedback and attenuated stage bleed.
The mic delivers a frequency response of 50 Hz to 15 kHz with a gentle presence boost peaking at approximately 6.5 kHz. Its XLR 3-pin output ensures compatibility with most mixer inputs, microphone preamps, and portable PA systems. An on/off switch is provided for convenient muting of the mic between speeches or performances. The attached, self-tensioning, 5/8“-27 thread swivel mount can be tilted up to 45 degrees forward and 80 degrees backward. Chrome die-cast metal construction provides tour-worthy durability.
Classic Appearance
In addition to being a mic with solid audio characteristics for the studio and stage, the 55SH Series II makes a great prop microphone in video shoots, photos, and theater applications
Tailored Frequency Response
The 50 Hz to 15 kHz frequency response features a slight dip in the low-mid frequency range and a gentle rise from 1 to 10 kHz, making its sonic performance optimized for vocals, public address, and dialog
Cardioid Polar Pattern
The cardioid polar pattern is effective in minimizing sound pickup at the off-axis sections of the capsule, ensuring high gain before feedback
Shock-Mounted Cartridge
The dynamic capsule is shock-mounted for added protection against shock- and structure-born noise

| The legendary Shure vocal mic is tuned to accentuate the warmth and clarity of lead and back-up vocals. Consistently the first choice of performers around the globe. The Shure SM58? is a unidirectional (cardioid) dynamic vocal microphone designed for professional vocal use in live performance, sound reinforcement, and studio recording. A highly effective, built-in, spherical filter minimizes wind and breath "pop" noise. A cardioid pickup pattern isolates the main sound source while minimizing unwanted background noise. The SM58 has a tailored vocal response for a sound which is a world standard. Rugged construction, a proven shock mount system, and a steel mesh grille ensure that even with rough handling, the SM58 will perform consistently. Outdoors or indoors, singing, speech - the SM58 is the overwhelming choice of professionals.

| 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
| Optimized for low-frequency bass punch/high-power SPL handling. Designed for kick drum.
The Shure BETA®52A is a high output dynamic microphone with a tailored frequency response designed specifically for kick drums and other bass instruments. It provides superb attack and "punch“, and delivers studio quality sound even at extremely high sound pressure levels.
The Beta 52A features a modified supercardioid pattern throughout its frequency range to insure high gain-before-feedback and excellent rejection of unwanted sound. A built in dynamic locking stand adapter with an integral XLR connector simplifies installation, particularly if the microphone is to be placed inside a kick drum. The stand adapter keeps the microphone position fixed and resists slipping, even when subjected to sharp blows and strong vibrations. A hardened steel mesh grille protects the Beta 52A from the abuse and wear associated with touring.

APPLICATIONS
Some typical applications for the KSM141 are listed below. Microphone use, however, is a matter of personal taste. The KSM141 may be used for a variety of applications other than those listed.
- Acoustic instruments -- such as piano, guitar, drums, percussion, strings
- Wind instruments -- brass and woodwind
- Low frequency instruments -- such as double bass, electric bass, kick drum
- Overhead miking -- drums or percussion
- Ensembles -- choral or orchestral
- Room ambiance pick-up -- guitar amplifier or drums
Both the acoustic environment and microphone placement strongly affect the sound obtained from miking a source. You may need to experiment with microphone placement and room treatments to achieve the best overall sound for each application.
