CAD CM100 Hanging Condenser Microphone
The CM100 is one of the finest values in choir microphones available.
The CAD CM100B microphone is a superior low noise, electret-condenser, cardioid choir mic. The CM100 has a wide, flat frequency response, which provides unsurpassed, natural, transparent sound quality.
Its cardioid pickup pattern minimizes annoying feedback when used close to sound reinforcement speakers and monitors, while reducing the pickup of unwanted off axis sounds.
Frequency Response: 40Hz - 20kHz.
CAD Quality
All CM100 microphones are audio tested and inspected prior to shipment. CAD's absolute commitment to quality insures that their microphones remain the Best Value in today's competitive industry.
Microphone Operation and Maintenance
If the mike housing becomes soiled by dirt or residue it may be cleaned using a cloth dampened with isopropyl alcohol.
User Techniques and Applications
The CM100 choir microphone is very light weight and can be hung in variety of ways such as a through a small opening in a suspended ceiling, suspended by a small hook in an overhead beam, or any means that is convenient. Once the microphone is suspended, bend the gooseneck so that the microphone points towards the desired sound source.
To prevent the microphone from turning away from the sound source over time, the microphone can be secured with monofilament fishing line. The microphone head has a small hole in it for this purpose. Secure the ends of the line to opposite walls of the room and through the hole in the microphone as shown in the photo on the front of this spec sheet. Use the smallest available line and it will be virtually invisible in the room.
