HiFi Audio Monitoring DIY Microphone Amplifier Board Noise ReductionDC9-15V
2. Exquisite appearance, beautiful arrangement of components
3. Adopt low noise audio processing chip plus high fidelity diaphragm condenser microphone, can directly monitor the scene of the subtle sounds
4. With a fine-tuning resistor, you can adjust the sensitivity, easy to change the distance and range of the monitoring
5. Can be used in places that need to monitor, can do monitoring synchronous recording and other ancillary equipment. With the amplifier can also do the shouting device, the use of two modules can do the intercom system, etc., the application range is extremely wide!
Can work for a long time in -20 ° C ~ +60 ° C temperatures
Power supply: DC9-15V, more than 100mA, recommended 12V
Static current: 3.5mA
Frequency response: 20Hz~20KHz
Sensitivity: >150mV
When the sensitivity is adjusted to the maximum of 200 square meters within the listening place can be clearly heard
Power supply polarity with anti-reverse protection, to effectively avoid the power supply reversal or lightning damage to the module
When the signal is too strong, or the monitor and the speaker is too close, there may be blocking or self-excitation phenomenon, at this time the volume of the amplifier to turn off some, or adjust the module on the fine-tuning resistor to reduce the amplification can be solved!
