Sony ECM-MS908C Operating Instructions - Page 2

Before operating the unit, please read this manual thoroughly and retain it for future reference. Features This microphone is a stereo microphone, attached externally to a video camera, that can capture sound with high quality. It works with any video camera that supports a microphone input terminal and an accessory shoe. • The MS (Mid-Side) Stereo System enables a natural sound pick up, delivering a stereo sound image with superb clarity. • The directive angle (between left and right channels) can be set to 90° or 120° according to the sound source. •• A custom extension arm allows you to use the microphone apart from the video camera, thereby cutting mechanical noise interference during sound pickup. Precautions • The microphone should never be dropped or subjected to extreme shock. • Keep the microphone away from extremely high temperatures and humidity (above 40°C or 104°F). • If the microphone is placed near loudspeakers, a howling effect (acoustic feedback) may occur. If this happens, place the microphone as far as possible from the loudspeakers, change the direction of the microphone or decrease the speaker volume until the howling stops.
