Nady Systems SCM920 Using the Optional Microphone Shock Mount, Using the Foam Windscreen, Service

WARNING

The capsule is the heart of your condenser microphone. If it become 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. Before connecting to a mixer directly, turn the channel to which you’re connecting to its lowest gain setting. If you are using the Nady SMPS-1 Phantom Power Supply, connect in the following order:

1.Connect the SCM 900/910/920 to the SMPS-1

2.Connect the SMPS-1 Signal Output to your mixer

3.Connect the SMPS-1 to the AC power supply (115—230VAC)

4.Turn on the SMPS-1 Power ON/OFF switch

5.Slowly turn up the channel gain in your mixer to the desired level
