KTV battery analysis microphones can be divided into dynamic microphone and condenser microphone. The working principle of dynamic energy conversion is different. Generally, condenser microphone consumes more power than dynamic microphone.
KTV battery analysis microphones can be divided into dynamic microphone and condenser microphone. The working principle of dynamic energy conversion is different. Generally, condenser microphone consumes more power than dynamic microphone. In general, we choose to need an external power supply for condenser microphone power supply enterprises on the market, while dynamic microphone chooses No.5 battery as power supply.
Water wood years recommend microphone battery consumption fast reason:
1. For wireless microphones that use No.5 batteries for transmission, when the voltage of the battery system is seriously low, the frequency drift problem is serious, and it deviates from the frequency point of social work, noise like tide will be generated, and the power consumption can be very fast at this time.
2. The distance between the microphone transmission and the receiver is too far, beyond the working range, and the battery consumes fast.
3. The microphone may be leaking. Measure the operating current of the wireless microphone. Open the battery cover, take out the battery, connect the negative pole, use a multimeter to 100 mA the current when plugging in, connect the red stylus to the positive pole of the battery, and connect the negative pole to the positive pole of the microphone battery connector.
KTV Battery
When the switch is turned on, the observed quiescent current, which should be about 15 mA, is advertised into the microphone and should vary between 15 mA and 25 mA. If the current exceeds this range, there is leakage in the microphone circuit. Therefore, fast battery consumption.
4. Poor battery quality. May be able to buy cheap products backlog problem for a long time expired battery, consumption fast, not durable.
