- OmniDirectional Polar Pattern
- Equally sensitive to sound from all directions, but cannot be "aimed" to isolate one area.
- Tailored Frequency Response
- Smooth, extended response. Tuned to accentuate specific types of instruments, or voices.
527B & 527CVoice Communication Microphones
Shure
- Dynamic
- Simple, rugged diaphragm/coil. handles extreme volume levels without distortion.
- Recommended Uses
- Paging
Additional Recommended Uses:
- Intercom
- Two-Way Radio
Designed for communication systems — mobile and fixed station — including police, fire, utilities, transportation, commercial, and industrial applications.
Note: The 527B does not require DC power for operation; however, the 527C requires DC power (4 to 35 Vdc @ 16mA).
- Frequency response designed for voice communications
- Omnidirectional mic element
- Rugged, high impact ARMO-DUR® case
- Double-pole, single-throw PTT switch designed for constant usage
- Four conductor, shielded, bare-ended (no connector) coil cord
- 527B does not require DC power for operation; 527C requires DC power for operation (4 to 35 Vdc @ 16mA)
- Mounting bracket included
- Type
- Dynamic
- Frequency Response
- 60 to 11,000 Hz
- 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.
