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. |
Shure MX202B-C Microflex Overhead Cardioid Condencer Microphone
It is hard to believe that such small, unobtrusive microphones can produce such great sound,
but it's true. Available in black or white finishes, and with in line or plate mount preamps, the
Microflex? Overhead condenser microphones capture Shure quality sound in a compact, adjustable
package. Each model features a choice of interchangeable cardioid, supercardioid and omnidirectional
condenser microphone cartridges attached to a flexible, four inch gooseneck with a 30 foot cable.
The preamp options available offer easy installation in ceilings or microphone stands, and when combined
with the high sensitivity cartridge's wide frequency response, these microphones provide accurate sound
reproduction with a minimum of RF interference or electromagnetic hum.
Features:
Wide dynamic range and frequency response for accurate sound reproduction across the audio spectrum
Interchangeable cartridges that provide an optimal polar pattern choice for each application
Balanced, transformerless output for increased immunity to noise over long cable runs
Supplied stand-mount adapter for portable applications (in-line preamplifier versions only)
White or black finish that blends unobtrusively with most surroundings

Relative Humidity: 0 to 95% | The C 414 B/XLS has been carefully designed to maintain the legendary sonic character of the C 414 family while integrating new features and performance enhancements made possible by new technology. The C 414B/XLS is designed to deliver accurate pickup of all acoustic instruments and voices.
The microphone's 5 pickup patterns are easily selectable via an electronic switch with LED indication and offer the selection of omnidirectional, cardioid, wide cardioid, hypercardioid and figure-eight patterns.
The pickup pattern selector switch utilizes a dual-color LED indicator that provides visual indication of the pattern selected and also changes from green to red to indicate if the microphone's output electronics are being overloaded. The pattern selector can also be used to "lock" the microphone's switch settings by pressing and holding it for 3 seconds.
On the rear of the microphone, an electronic switch allows the selection of -6 dB, -12 dB and -18 dB pre-attenuation levels which are accomplished by changing the polarization voltage to the capsule. The C 414 B/XLS has switchable bass cut filters of 12 dB-per-octave at 40 Hz and 80 Hz, and a 6-dB-per-octave filter at 160 Hz for control of proximity effect. On-axis sensitivity for all patterns is 23 mV/Pa and its self-noise is an extremely low 6 dB-A.
The C 414 B/XLS has a transformerless output and all-metal chassis, making it immune to electrical interference and RF from digital equipment, video monitors and wireless systems. It comes complete in an all-metal road case with the AKG H-85 shock mount, a PF80 external two-stage pop filter, a W414X external windscreen and an individually-measured chart showing the response curve of the microphone. It is also available in factory-matched stereo pairs packaged with a H50 stereo bar instead of the external pop filter.
The C 414B/XLS is built in Vienna, Austria and comes with a three-year limited parts and labor warranty.

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.
