SCM 900

USER GUIDE

Congratulations on purchasing a Nady SCM 900 Condenser Microphone. These superior microphone is perfect for recording studio vocals, acoustic instruments, orchestras and choral groups, ambient instrument audio, and many live sound applications. Powerful and versatile, the SCM 900 microphone meets the stringent requirements of even the most demanding digital recording and live broadcasting applications.

This manual covers the operation of the SCM 900 microphone and the available optional accessories. To take full advantage of the superb features of your microphone, and to enjoy long and trouble-free use, please read this user’s guide carefully.

UNPACKING, INSPECTION, STORAGE AND TRANSPORT

Your SCM 900 microphone was carefully packed at the factory, and the shipping carton (or carrying case) was designed to protect the unit during shipping. Please retain this container for subsequent transport and in the highly unlikely event that you ever need to return your microphone for servicing. The optional SMCC-2 aluminum carrying case is highly recommended for the most convenient and safe transport or permanent storage. It has roomy compartments for your SCM 900 microphone and all available accessories, plus XLR cables.

FEATURES & OPERATION

 

The SCM 900 microphone offers transformerless balanced outputs and true condenser design (elements constantly biased by the pre-amp) for exceptionally low self noise and increased dynamic range, enhanced low and high end response with improved linearity across the frequency range and maximum SPL capacity. Internal Low Cut fi lter switch to minimize pop sound and stage rumble.

SCM 900 microphone features a large diaphragm capsule (1.0 inch), hand tooled from brass and featuring an ultra-thin (3- micron) gold-evaporated on Mylar diaphragm for maximum sensitivity, transient response, long life, detail and tone.

The microphone uses carefully selected Field Effect Transistors (FET), specially chosen for their low distortion and superior signal-to-noise ratio. (Note: For optimum performance, it is best to let your microphone warm up for 5 to 10 minutes)

SCM 900 is manufactured with the fi nest materials and features a machined housing with advanced internal shock mount construction for the highest structural integrity and rugged reliability. It requires 48V phantom power to operate, typically supplied by the microphone pre-amplifi er 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 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 900 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 traffi c 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 900 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. This windscreen fi ts 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

The SCM 900 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 amplifi ed 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 amplifi ers and too little may result in a noisy signal)

The SCM 900 can be connected to your mixer or phantom power supply using a standard balanced 3-pin XLR microphonecable. 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 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

The internal Low Cut fi lter push-button switch can be accessed by carefully unscrewing the bottom ring of the mic and sliding off the housing. Take care not to damage the pcb or internal components during this procedure.
