Product Description

The 512 headset microphone consists of the popular SM10A microphone element mounted on a lightweight headband with a single earphone. The Model 512 mic combines an efficient "open-air" headphone with a close-talking dynamic microphone. The unit is unobtrusive, durable, comfortable, and provides a wide frequency range.

Type Dynamic, close-talking

Polar Pattern Cardioid (unidirectional) response uniform with frequency, symmetrical about axis

Impedance Microphone rating impedance is 150 Ohms (200 Ohms actual) for connection to microphone inputs rated at 19 to 300 Ohms. Output Level (closed-talked at 1,000 Hz) Open-circuit voltage: -47.0 dB (4.5 mV) 0 dB=1 volt per 100 microbars

Power Level: -66.0 dB
0 dB=1 milliwatt per 10 microbars Hum Sensitivity (typical) 38.4 dB equivalent SPL in 1 millioersted field Polarity Positive pressure on diaphragm produces positive voltage on red lead and pin 2 of connector. HEADPHONE

Type Dynamic, open-air, left side only Frequency Response 100 to 10,000 Hz, tailored for voice intelligibility (see Figure 3). Impedance 300 Ohms at 1,000 Hz Polarity Positive voltage on cable conductor produces positive pressure. Output Level (at 1,000 Hz) 94 dB SPL at ear with 1 mW input MATERIAL
