CAD CM100B 100-Series Overhead Choir Condenser Microphone (Black)

The CM100 microphones have a wide, flat frequency response which provides unsurpassed, natural, transparent sound quality. Their cardioid pickup pattern minimizes annoying feedback when used close to sound reinforcement speakers and monitors, while reducing the pickup of unwanted off-axis sounds.

The CM100's electronics are located externally in a housing which also contains the professional 3-pin male XLR connector. The CM100 is attached to this with a 30 ft. cable terminated with a mini 3-pin XLR. The CM100 is finished in durable black urethane paint with a flexible PVC covering over the gooseneck.

The CM100 features a .022 in. diameter hole placed directly behind the microphone head that facilitates the use of monofilament line to inconspicuously fix the position of one or a series of microphones.

About CAD
CAD Professional Microphones, a division of CTI Audio, designs and manufacturers professional microphones in its state-of-the-art USA facility, located in Conneaut, Ohio. An influence in the development of microphone technology over the last decade, the company made its mark bringing distinction to reasonably priced mics, revolutionizing the studio mic market. As the word got around, other manufactures began to follow suit and new competitors entered the marketplace. This is most obvious in the studio condenser arena, where dozens of models have been introduced over the last 2 years. While promising the sound of the revered "vintage" mics, most of these new "classics" are made in the Far East, many in the same factory.

CAD designers have remained focused on the factors that make a great mic sound great: High sensitivity, transparency, precise transient, phase response, wide frequency response, and extremely low self noise. The microphone's capsule must capture the impact, tone, ambience, and nuances of an instrument or voice. CAD's renowned Optema capsules are 24K gold sputtered and hand dampened in CTI's clean room facility. Like only a handful of true microphone manufactures, CAD maintains it own manufacturing facility in the USA. This gives CAD designers control over every aspect of the mic's design, performance, and quality.

CTI Audio's roots go back to the 1930's, when they developed many innovative mic designs, including the T2, possibly the world's first dual tube condenser mic. CAD's celebrated Equitek studio condensers became associated with the explosive project studio market, and a requisite for the sound of the urban music styles of the 90's. When conservative engineers and producers began to discover and demand CAD, the brand became established as a standard. Today, CAD is looked to for their first class design, and for microphones unparalleled in their ability to memorialize the recordings they're used on.
