About the Nady CBM-40X

The Nady CBM 40 Boundary Microphone is a wide-range back electret condenser with a cardioid polar pattern. It is very useful in a variety of surface-mounted applications such as high quality sound reinforcement, professional recording, and many other demanding sound pickup situations.

The microphone is designed to be powered by an external 9-52 V DC phantom power supply and is enclosed in a heavy-duty die cast case on rubber padding to minimize mechanical coupling of surface vibrations to the microphone.

The CBM 40 can be used with any standard mixer, powered mixer/amplifier, or mic preamp which provides 9-52V phantom power.

The optional Nady 48V SMPS-1 Phantom Power Supply can also be used if your mixer doesn't supply phantom power. Connect the supplied mini-XLR to XLR cable directly to your equipment, or use an XLR to XLR balanced low impedance cable as an extension if needed.

Although all microphones are prone to feedback to some extent, those with a unidirectional polar pattern (such as the CBM 40) are specially designed to accept only signals from audio sources in front of the mic element.

Thus, the half cardioid pattern of the CBM 40 ensures that it will deliver only the desired audio in front of the mic, rejecting the unwanted audio from the rear, even in noisy ambient conditions with high sound pressure levels from the P.A. and monitor speakers.

This means that feedback will be greatly minimized with the CBM 40 in all live performance micing applications.
