- Cardioid Polar Pattern
- Picks up the most sound in front of the microphone and some from the sides. Less susceptible to feedback in high volume environments.
- Tailored Frequency Response
- Smooth, extended response. Tuned to accentuate specific types of instruments, or voices.

View Larger - Polar Pattern
- Cardioid (unidirectional) - uniform with frequency, symmetrical about axis
- Impedance
- Dual. Microphone rating impedance is 150 ohms (260 ohms actual) for connection to microphone inputs rated at 19 to 300 ohms and "High" for connection to high-impedance microphone inputs. Switch is in high-impedance position as supplied. To change impedance, see sections on lmpedance Selection and Connections in User Guide.
- Sensitivity (AT 1,000 Hz):
- LOW: Open Circuit Voltage* -57.5 dB Ref. 1V/Pascal (1.3 mV)
- HIGH: Open Circuit Voltage* -38.5 dB Ref. 1V/Pascal (12 mV)
- *(1 Pa = 94 dB SPL)
- Switch
- Press-to-Talk Switch - locking or nonlocking operation to actuate microphone circuit and an external relay or control circuit. Microphone circuit normally shorted in both high and low impedance.
- Impedance Selection Switch - double-pole double- throw slide switch in microphone base to provide either high- or low-impedance operation.
