    PULUZ 48V Phantom Power Supply for Condenser Microphone(Black)

    Features48 volt phantom power is what powers condenser microphones. The polar plate of the condenser head in the condenser microphone needs a certain voltage to establish an electric field to work (the electret microphone does not need a 48-volt phantom power because it has a resident polarized electric field), while the microphone amplifier (also called the pre-amplifier) in the condenser microphone ) is also powered. Therefore, the main function of the 48-volt phantom power is to supply power to the condenser head and microphone amplifier in the condenser microphone. 1. Adopt power boost isolation technology to effectively prevent the ground wire signal from interfering. 2. The built-in low-pass filter circuit design can fully filter out the interference noise of external audio equipment. 3. Two sets of balanced power supply, balanced input and output signals, so as to stabilize the voltage balance and suppress common mode interference. 4. Using the new low-voltage power supply technology of USB 5V booster circuit to prevent harm to the human body, and solve the problem of incompatibility of transformers due to regional mains, different voltages.Specifications1.
