SPECIFICATIONS Output Level (at 1000 Hz) Low lmpedance .................... Open Circuit Voltage - 78 dB* (.I25 mV) .................................... Power Level -57 dB** Type Dynamic Frequency Response 50 to 15,000 Hz (see Figure 1) FREQUENCY RESPONSE FIGURE 1 Polar Pattern Cardioid (unidirectional) pattern-Effective rejection of sound at the rear of the microphone is uniform at all frequencies, while front pickup characteristics are uniform about the axis (see Figure 2) I TYPICAL DIRECTIONAL PATTERN I FIGURE 2 Impedance DUAL. Low: Microphone rating impedance is 150 ohms (270 ohms actual) for connection to microphone inputs rated at 19 to 300 ohms. High: Microphone impedance is "High" for connection to high-impedance microphone inputs. Selection of impedance made by choice of cable leads connected at equipment end of cable (see section on lmpedance Selection).
