Sony ECM-MS2 - Electret Condenser Microphone Manual

Features

MS stereo for natural sound tone and localization
MS stereo captures the surrounding sound field reliably with natural sound tone and localization.
Monaural recording support
Monaural recording is supported simply by not connecting the R channel cable.
Strong wind screen attached for strong winds
Reduces noise caused by strong winds in outdoor and other affected environments.
Compact and lightweight
Length of 137 mm and mass of 160 g, making it easy to use and carry.
External power supply type
Supports 40 V to 52 V DC external power supply.

Names and Functions of Parts

Microphone
When mounting the microphone on a camcorder, make sure that the "UP" mark on the microphone's label is facing up.
Output connectors (XLR-3-12C type) (white: L channel, red: R channel)
Outputs the sound captured by the microphone. It also supplies power from the external power supply.
Wind screen
Attach to the microphone to reduce wind and breathing noise.
Cable tie
Use this to bundle and fasten the microphone cable.

Sound Pickup Mode

The sound pickup mode is determined by the power supply status from an external device to the L and R channels, or by the sound pickup mode configured on the camcorder, as shown in the following table. If the R channel connector is not connected, sound pickup will be in monaural mode.

Sound pickup mode	Power supply to L and R channels / camcorder setting
Stereo	L: ON; R: ON / Stereo
Monaural	L: ON; R: OFF / Mono

For details on menu operations on the camcorder, refer to the operation manual supplied with the camcorder.

Power Supply

This microphone is powered only from an external supply. Connect the output connector of the microphone to an external power supply device, such as a Sony AC power supply or equivalent device, or the microphone connector of an audio mixer or camcorder.

Notes

Before connecting the microphone to a camcorder or other device, check that it is equipped with a 40 V to 52 V microphone input connector.
An unbalanced cable cannot be used with this microphone. Be sure to use a balanced microphone cable.

Notes on Use

Microphones are delicate. Do not drop, hit, or subject it to excessive shock.
Avoid extended usage or storage in high humidity or temperatures above 60°C (140°F).
If acoustic feedback occurs during use (a howling sound is heard from the speakers), point the microphone away from the speakers or increase the distance between the microphone and the speakers.

1) 0 dB = 1 V/Pa, 1 kHz
2)0 dB SPL = 2 × 10⁻⁵ Pa
3)Wind noise is the value measured by applying a wind velocity of 2 m/s (6.6 ft/s) to the microphone from all directions. The noise output mean value is converted to the equivalent input sound pressure level (0 dB SPL = 2 × 10⁻⁵ Pa).

Design and specifications are subject to change without notice.
