General
The Model 300 ribbon microphone is a rugged stand-mounted unit with a wide range frequency response and a bidirectional polar pattern. The Model 300 is an excellent choice for broadcasting or recording studios as well as for critical sound reinforcement ap­pli­ca­tions. The microphone’s symmetrical front and rear and its greatly reduced side pickup make it ideal for such uses as across-the-table interviews or dialogue, stages with loudspeakers directly to the side or overhead, and combined pickup of facing instrumental groups in recording sessions.

The Model 300 is supplied with a Voice/Music switch that provides either flat or rolled off low frequency response and with an impedance-selection switch allowing choice of three rated impedances: “L”—38 ohms, “M”—150 ohms, and “H”—high impedance. A built-in vibration isolator and internal ribbon protection make the microphone suitable for a wide variety of applications.
