ECM-MS2
Electret Condenser Microphone
Affordable compact stereo microphone, ideal for
mounting on professional compact camcorders
MAIN FEATURES
n Short and Compact
The compact 137 mm length of the Sony ECM-MS2 prevents
inadvertent vignetting of the microphone when it is attached
to a handheld professional camcorder such as the PMW-100.
Additionally, this short length is convenient when packing and
transporting the microphone with a compact camcorder.

n Stereo and Mono Operation
The ECM-MS2 offers mono operation when stereo is not
required, simply by cutting off the power supply to the right
channel. For example, when a wireless microphone system is
connected on one channel while recording environmental
sounds on the other channel. The microphone is designed
for applications such as news gathering and documentary
shooting on location.

n Professional Quality
Professional quality is assured by XLR3P outputs which
enable connection to professional camcorders for 48-volt
phantom powering. The microphone’s metal body also
enhances audio performance by blocking vibration,
resonance, and RF noises.
n Unique Accessory
The supplied furry wind screen is
used to suppress the strong wind
present in typical harsh-climate
operating conditions. A cable tie
is also supplied to fasten the
unplugged microphone cable
during mono operation.
