Label:Yes Working current: 3.1ma Signal-to-noise ratio (SNR): 60db Sensitivity:-48db Board size: 45 * 16mm The maximum sound pressure level: 125db Packing List:1Pc Microphone Condenser Frequency response: 40hz-16khz Output Impedance: 250 ohms Product Description: 1. Polarization voltage plates can be applied to other transistors pre-board suitable for manual ability of friends DIY, no hands-on ability of friends please buy our qian zhi ban + polarizing plate 2. Single 60V output +-60V dual output, double + 60V dual input, + 60V and + 120V dual output, can be customized according to the large diaphragm of the polarization voltage selection, single output is suitable for use in a single-layer film microphone, dual output bilayer film microphone 3. It is recommended to use the + 60V and + 120V dual output, if the 60V thought sound is not big enough, sensitivity is not high enough, it is possible to switch 120, can be connected to a switch Use your microphone microphone type: large diaphragm, the vibrating membrane capacitance microphone (for diameter 25mm or below the diaphragm)
