IEC711 1/2" ICP Microphone Preamplifier Mic Preamplifier Mic Preamp with BNC Connector for GRAS B&K
Description:
ICP preamplifier is a kind of preamplifier powered by a constant current source. It features high input impedance, low output impedance and low noise. It combines the signal line and the power line into one, and its output adopts BNC connector which can be easily connected to the BNC input end of general measuring instrument. It is compatible with Φ12.7 mm (1/2 inch) pre-polarized measurement microphones.
Specifications:
- Dimensions: Φ12.7 mm (1/2 inch)
- Frequency range: 20Hz~50kHz ±0.2dB ; 10Hz~100kHz±0.5dB
- Power supply: ICP (2mA ~10mA)
- Output connection: BNC connector
- Microphone thread: M11.7 mm x 0.423 mm (60 UNS)
Circuit Connection Method:
+24V is preferred for power supply voltage, and 2mA~4mA is preferred for constant current source. If there is no constant current source, a resistor can be used instead. The resistance value can be 3kΩ~5kΩ and make sure that the operating current is 2mA~4mA.
Package Included:
- 1 x Mic Preamp
Packaging Details:
- G.W.: 0.25kg
