Sony ECM-MS2 Compact Electret Condenser Microphone

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.

Key Features

• 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 microphone’s metal body enhances audio performance by blocking vibration, resonance, and RF noises
• The ECM-MS2 provides an electronically balanced output operation on 48 V standard external power
• A cable tie is supplied to fasten the unplugged microphone cable during mono operation
• The ECM-MS2 offers mono operation when stereo is not required, simply by cutting off the power supply to the right channel
• 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
• The supplied “feather boa like” windscreen suppresses the strong wind noise typical of harsh-climate operating conditions
