MX202 Microflex Overhead Microphones

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, MX202 Microflex® Overhead condenser microphones capture high-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.

Interchangeable cartridges and accurate sound reproduction in an unobtrusive overhead microphone. Easy to aim and features a non-twist cable.

• 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

The polar pattern of the cartridge is indicated by the model number suffix:

C = Cardioid, S = Supercardioid, N = No cartridge
