SPECIFICATIONS:

• For advanced amateur use 

• Video camera shoe attachment fits beautifully on most camcorders 

• Extension arm holds the ECM-908C away from the camcorder body, reducing the transmission of mechanical noise 

• Stereo sound takes advantage of the two-channel sound tracks on many of today's top camcorders: DV, Digital8, Hi8, 8mm, VHS, S-VHS and VHS-C formats all offer the option of stereo sound; check your camcorder for compatibility 

• Inconspicuous, compact design for easy portability 

• One-point stereo design -a single mic for stereo recording-is like having two microphones in one 

• Mid/Side (MS) capsules for natural stereo panorama; the Mid capsule picks up monophonic sound while the Side capsule picks up left/right difference sound; subtracting and adding the two capsule signals yield separate Left and Right channels-also permit electronic adjustment of pickup angle 

• Mid/Side (MS) switch lets you select the "spread" between left and right channels according to the camera zoom, the environment and the shooting situation; choose 90° for close-ups and noisy environments; choose 120° for wide shots and quieter environments
