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 10’cable to connect to two channels of
your mixing console or recording equipment.

OPTIONAL ACCESSORIES

• Camera Shoe Mount Adapter

• MST-5B Boom mic stand

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.)
