Thanks for purchasing the Nady OHCM-200 Overhead Hang-ing Condenser Microphone! This microphone is a wide-rangeback electret condenser with a cardioid polar pattern. It is veryuseful in a variety of overhead hanging mic applications suchas high quality sound reinforcement, professional record-ing, and many other demanding sound pickup situations. Themicrophone is designed to be powered by an external 9-52 VDC phantom power supply and is enclosed in a rugged die castcase for long-term reliability.UNPACKING, INSPECTION, STORAGE AND TRANSPORTYour OHCM-200 microphone was carefully packed at the fac-tory, and the shipping carton was designed to protect the unitduring shipping. Please examine your microphone before usingand retain the external shipping package for reuse should youever need to return your microphone for servicing.USING YOUR OHCM-200The OHCM-200 can be used with any standard mixer, powered mixer/amplifier, or micpreamp which provides 9-52V phantom power. The optional Nady 48V SMPS-1 PhantomPower Supply can also be used if your mixer doesn’t supply phantom power. Connect thesupplied mini-XLR to XLR cable directly to your equipment, or use an XLR to XLR bal-anced low impedance cable as an extension if needed.The OHCM-200 should be placed at the desired location and aimed at the sound source.The hanging wire must be attached at an appropriate spot to support the mic and allowproper stable aim at the source. Experiment with your mic and and its placement and youwill find it to be a useful tool in many applications. Although designed primarily for highquality far field pickup of audio, such as for use with choirs and stage plays, the NadyOHCM-200 can also be used in many creative applications. For example, it can also be usedclosed field to pickup audio from instruments and percussion. Be aware of the proximityeffect (an increase in bass response) when the mic is placed close to the instrument. Thismay or may not be desirable. Experimenting with the position of the mic with respect to theaudio source will ensure the optimum results you are seeking in any given application.If the microphone is placed too near a speaker during live stage use, an unpleasant howl-ing effect (acoustic feedback) may occur. Although all microphones are prone to feedbackto some extent, those with a unidirectional polar pattern (such as the OHCM-200) arespecially designed to accept only signals from audio sources in front of the mic element.Thus, the cardioid pattern of the OHCM-200 ensures that it will deliver only the desiredaudio in front of the mic, rejecting the unwanted audio from the rear, even in noisy ambientconditions with high sound pressure levels from the P.A. and monitor speakers. This meansthat feedback will be greatly minimized with the OHCM-200 in all live performance mikingapplications. Of course, when using this mic in far field audio pickup applications, extracare must be taken to lessen feedback.Some useful ways in which to totally eliminate annoying feedback in live use include:experimenting with mic positions with respect to the speakers, decreasing speaker volume(whenever possible), and adjusting the equalization of the mic audio with the mixer.OHCM-200Overhead Hanging Condenser MicrophoneUSER GUIDE |
