Sony ECMMS2 Stereo Microphone

Sony ECMMS2 Stereo Microphone

Overview

Affordable compact stereo microphone, ideal for mounting on professional compact camcorders

The ECM-MS2 compact Electret condenser microphone is designed to work with handheld camcorders. The compact 5.39-inch length prevents the microphone inadvertently appearing in view and makes it easier to transport.

The ECM-MS2 offers both stereo and mono operation, increasing the versatility of the microphone. It is particularly useful for capturing accurate ambient stereo sound when dialog might be alternately captured with wireless microphones. This makes the ECM-MS2 very well suited to applications such as news gathering and documentary shooting on location.

Features

Compact lightweight design ideal for use with handheld camcorders
The compact 137mm length of the ECM-MS2 prevents inadvertent vignetting of the microphone in the view when it is attached to a handheld professional camcorder. The short length is also convenient for packing and transporting the microphone with a compact camcorder.

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. This capability is useful for recording environmental sounds with one channel, while the other channel is being used with an additional wireless microphone system.

Professional quality sound reproduction
The ECM-MS2 delivers professional-quality natural sound reproduction. It has a frequency response of 80 Hz to 20 kHz (stereo) and 70 Hz to 20 kHz (mono), excellent sensitivity of -32 dB (stereo) and -36 dB (mono), and an inherent noise level of less than 25 dB SPL.

Metal body reduces external noise
The microphones metal body enhances audio performance by blocking vibration, resonance, and RF noises.

External DC (40 to 52 V) operation
The ECM-MS2 provides an electronically balanced output operation on 48 V standard external power.

Original windscreen protects from contact noise
The supplied feather boa like windscreen suppresses the strong wind noise typical of harsh-climate operating conditions.

Cable tie for bundling and fastening the microphone cable
A cable tie is supplied to fasten the unplugged microphone cable during mono operation.
