2. GENERAL DESCRIPTION

The EM-700 is a cardioid boundary condenser microphone suitable for installation on a lecture desk or table top in a conference room for sound pick-up and public address applications.

3. FEATURES

• Sound field characteristic correction in a condition being

placed on a flat surface such as a desk, realizing pure, natural sound quality.

• A low cut switch that effectively eliminates noises such

as vibration noise from the installation surface.

• High-quality, low-profile, and unobtrusive design

4. HANDLING PRECAUTIONS

• Be sure to turn off the phantom power switch on the equipment that the unit is connected to before connecting or disconnecting the unit. As doing otherwise may cause loud noise or damage to the unit or connected equipment.

• Avoid installing the unit in humid or dusty locations, in locations exposed to the direct sunlight, near the heaters, or in locations generating sooty smoke or steam as doing otherwise may result in unit failure.

• Take care not to drop the unit onto the floor nor bump it against a hard object as the unit could fail.

• Avoid using a mobile telephone near the microphone in use. Noise could be picked up.

• To clean, be sure to first disconnect the connection cable, then wipe with a dry cloth. When the unit gets very dirty, use a cloth damped in a neutral cleanser. Never use benzene, thinner, alcohol, or chemically-treated cleaning cloth because such volatile liquids could deform or discolor the unit.
