FEATURES

Back electret condenser microphone designed for cymbals of all types (including rides, crashes and hi-hats), reeds, acoustic guitars, piano and vocals (with the accessory windscreen) and overhead applications (both live and recording) Extremely uniform and tight cardioid polar pattern for ease in mixing Extended frequency response for smooth, crisp, ultra-transparent reproduction Aluminum housing and gold-plated XLR contacts 9-52V phantom powered

CONNECTING THE CM 88

The CM 88 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 standalone unit). (Note: Make sure to set the pre-amp to the proper gain leveltoo much gain may distort subsequent amplifiers and too little may result in a noisy signal) The CM 88 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 youre 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 CM 88 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

USING YOUR CM 88

Depending on the application, the CM 88 can either be handheld or mounted on a microphone stand with a standard mic clip. Be aware of the proximity effect (an increase in bass response) when the mic is placed close to the mouth or instrument. This may or may not be desirable. Experimenting with the position of the mic with respect to the audio source will ensure the optimum results you are seeking in any given application. Also, never place your hand over the balIscreen of the mic during use, as this can degrade the performance. If the microphone is placed too near a speaker, an unpleasant howling effect (acoustic feedback) may occur. Although all microphones are prone to feedback to some extent, those with a unidirectional polar pattern (such as the CM 88) are specially designed to accept only signals from the audio source directly in front of the mic cartridge. Thus, the cardioid pattern of the CM 88 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 PA and monitor speakers. This means that feedback will be greatly minimized with the CM 88 in all live performance miking applications. Some useful ways in which to totally eliminate annoying feedback 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.

PRECAUTIONS AND CARE OF YOUR CM 88
The capsule is the heart of the 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. The microphone should never be dropped or subjected to extreme shock. Store only in a padded case to protect it during transport. Keep the microphone away from extremely high temperatures (above 140F or 60C) and humidity. Avoid leaving the microphone in direct sunlight for long periods of time. When using the microphone outdoors, avoid getting it wet. After use in a high-moisture application such as a stage performance, wipe off the microphone with a dry cloth and permit it to air dry. Do not store the unit in a closed space (e.g., a plastic bag) until all moisture has evaporated. The CM 88 is supplied with a foam windscreen. 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 windscreen should be used whenever someone is close miked to both protect the microphone and to also eliminate popping sounds from percussive breath sounds. (Note: Be aware that the foam windscreen will slightly attenuate the high frequency response of the microphone.)

CM-2S Stereo Condenser Microphone

USER GUIDE

Congratulations on purchasing the Nady CM-2S Stereo Condenser Microphone. This superior, versatile microphone provides the realistic spatial impact of a live sound field for many applications including stereo recording, ENG theater use, and FM stereo radio. This manual covers the operation of the CM-2S 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 users guide carefully.
UNPACKING, INSPECTION, STORAGE AND TRANSPORT
Your CM-2S microphone was carefully packed at the factory, and the shipping carton was designed to protect the unit during shipping. Please retain this container in the highly unlikely event that you ever need to return your microphone for servicing.

STANDARD ITEMS SUPPLIED

CM-2S Stereo Condenser Microphone Mic clip 19" (0.5m) stereo cable (XLRF to 3.5mm stereo mini plug) 10' (3m) stereo cable (XLRF to two 3.5mm mono mini plugs) Two 3.5mm (female) to 1/4" (male) phone plug adapters Foam windscreen Soft, protective leatherette pouch AA battery User guide Warranty card

OPTIONAL ACCESSORIES

Camera Shoe Mount Adapter MST-5B Boom mic stand

FEATURES & OPERATION

The CM-2S uses a pair of closely-matched, wide range, condenser uni-directional (cardioid) elements, angled at 110 in an X/Y stereo configuration. It features superb channel separation; smooth, linear 30Hz-20kHz frequency response with a switchable low-frequency roll-off; On/Off switch, high SPL capability; extended dynamic range with ultra-low self noise; crisp, clear transparent audio; and internal battery operation. All this contained in a compact, lightweight design for easy camera mounting The CM-2S has two unbalanced, in-phase, low impedance stereo outputs. The Left(+) signal is sent to Pin 2 and the Right(+) signal is sent to Pin 3. Both Left and Right use a common Ground(-) connection on Pin 1. Use the 19" stereo cable to connect to 3.5mm stereo inputs or the 10cable to connect to two channels of your mixing console or recording equipment. Placing the mic closer to the sound source will create a more pronounced stereo image while moving the mic further away will lessen the stereo image and result in more room noise. Placing a mic too close to a multi-voice source may result is some voices being more dominant than others. Experiment with placement for the best possible results. Use the low-cut filter switch to reduce stage floor noise and undesired low frequencies. Before operating, install an alkaline or mercury AA battery by unscrewing, and sliding down, the lower portion of the handle to reveal the battery compartment. The CM-2S is only designed for battery use. DANGER: DO NOT USE PHANTOM POWER WITH THE CM-2S OR YOU COULD DAMAGE THE MICROPHONE. Note: Low bias voltages (such as those used for mini-disc, DAT, or analog recorders) will not harm the microphone.
USING THE FOAM WINDSCREEN
The foam windscreen, supplied with the CM-2S, 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. (Note: Be aware that the foam windscreen will slightly attenuate the high frequency response of the microphone.) (WARNING: The capsule is the heart of the condenser microphone. If the elements becomes dirty or wet, the sound will be degraded. Never spray any liquid on the microphone head. Always use a foam windscreen or pop filter if you talk or sing close to the microphone grill screen.)
