[. . . ] NADY SCM SERIES USER GUIDE SCM 900/910/920 Studio Condenser Microphones Congratulations on purchasing a Nady SCM Series FET Condenser Microphone. These superior microphones are perfect for recording studio vocals, acoustic instruments, orchestras and choral groups, ambient instrument audio, and many live sound applications. Powerful and versatile, the SCM Series microphones meet the stringent requirements of even the most demanding digital recording and live broadcasting applications. SCM 900 SCM 910 SCM 920 This manual covers the operation of the SCM 900/910/920 microphones and the available optional accessories. [. . . ] It requires 48V phantom power to operate, typically supplied by the microphone pre-amplifier or mixing console. The optional Nady SMPS-1 phantom power supply can also be used. WARNING The capsule is the heart of your condenser microphone. If it becomes dirty or wet , the sound will be degraded. Never spray any liquid on the microphone head. Always use a foam windscreen if you talk or sing close to the microphone grill screen. USING THE OPTIONAL MICROPHONE SHOCK MOUNT Your SCM Series microphone can be used with the optional Nady SSM-3 spider shock mount (or equivalent), which uses an elastic suspension to isolate the microphone from vibration, thereby lowering noise transmitted to the microphone from the stand. This is a useful tool in many situations, such as when the performer is tapping his or her feet, or when there is noise pickup from the rumbling of traffic outside of the building. The disadvantage of using the shock mount is that the weight of the microphone may make it drift in the elastic suspension, so mic placement may take a little longer. To insert your SCM Series microphone into the SSM-3 shock mount, pinch close the levers on the sides of the mount to the open position, then slide the microphone into place. USING THE FOAM WINDSCREEN The FW-2 optional foam windscreen can also be used with your SCM 900/910/920. This windscreen fits over the grill portion of the microphone and is designed primarily to decrease bass rumble (from wind noise pickup during outdoor live or recording use. It is also useful in keeping mouth spray out of the microphone head. The FW-2 or some other windscreen should be used whenever someone is close miked to both protect the microphone and to also eliminate "popping" from percussive breath sounds. (Note: Be aware that the foam windscreen will slightly attenuate the high frequency response of the microphone. ) CONNECTING THE SCM 900/910/920 The SCM 900/910/920 can be used in live sound reinforcement and broadcasting and in studio or live recording. It must be powered by 48V phantom power (such as supplied by the optional Nady SMPS-1 phantom power supply or a mixing console with phantom powering), and amplified by a microphone pre-amp (such as built into a mixer, or a stand-alone unit). (Note: Make sure to set the pre-amp to the proper gain level--too much gain may distort subsequent amplifiers and too little may result in a noisy signal) The SCM 900/910/920 can be connected to your mixer or phantom power supply using a standard balanced 3-pin XLR microphone cable.
