Designed for paging calls and general announcements, the PM-660D desk-top microphone comes with a large talk switch and a lock lever for easy and convenient operation. Its robust anti-vibration construction and balanced output render the microphone resistive to noise. In addition, the PM-660U microphone is equipped with a remote control switch (interlocked with the talk switch) for amplifier power on/off operation or chime activation.

In the tradition of the SM58?, the Beta 58A dynamic microphone has become a top choice among vocalists and touring sound professionals.
The Shure Beta 58A is a high-output supercardioid dynamic vocal microphone designed for professional sound reinforcement and project studio recording. It maintains a true supercardioid pattern throughout its frequency range. This insures high gain-before-feedback, maximum isolation from other sound sources, and minimum off-axis tone coloration. The Beta 58A has a shaped frequency response that is ideal for close-up vocals. The superb performance of this microphone is not affected by rough handling because of its rugged construction, proven shock mount system, and hardened steel mesh grille. Typical applications for the Beta 58A include lead vocals, backup vocals and speech.
- Smooth, extended frequency response for outstanding sound for professional live vocal use
- Consistent supercardioid pattern provides the best gain-before-feedback among dynamic microphones
- Pneumatic shock mount reduces handling noise
- Frequency response: 50 to 16,000 Hz
-
Frequency response tailored for vocals, with brightened midrange and bass rolloff to control proximity effect
-
Uniform supercardioid pattern for high gain before feedback and superior rejection of off–axis sound
-
Neodymium magnet for high signal–to–noise output
-
Hardened steel mesh grille that resists wear and abuse
-
Advanced pneumatic shock mount system that minimizes transmission of mechanical noise and vibration
-
Minimally effected by varying load impedance
-
Legendary Shure quality and reliability

The APM series are digital paging microphones equipped with a condenser microphone with cardiologic characteristics, mounted on a 30 cm long gooseneck. By means of a built-in compressor / limiter, the output level of the microphone signal is constantly maintained. The status of the reproduced signal is indicated on the front panel, to ensure the speaker that the message is clear and audible in all situations. Each console has 3 standard buttons (except the APM01 which has only PTT) with pre assigned functions: PTT (Push To Talk), Select all and Clear. All other buttons can be freely programmed, using the free APM configuration software. |

| 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.
