The AU230 microphone features a novel appearance, clear sound quality, and a wide 20–20,000 Hz frequency response. Its circuit automatically adapts to phantom power (12–48V) without affecting dynamic range. With a cardioid pickup, high sensitivity, and RFI shielding, it delivers reliable performance for news broadcasting and conferences.
Product advantages
This microphone is novel appearance, excellent quality and high resolution. The circuit is specially designed to automatically recognize phantom power supply voltage.
It does not affect the dynamic range when using different phantom power supplies. The design does not affect the sight of the speaker and the audience and apply for news broadcast and conference. The product adopts Radio Frequency Interference (RFI) shielding technology to ensure excellent resistance to RF interference, such as from mobile phones.

Installation
Connect the extension rod to the base, mount the microphone onto the clip, and secure the cable. Connect the microphone to a mixer or audio input device, and adjust the pickup angle and volume to the desired levels.
For optimal sound reinforcement, the distance between the microphone and the sound source should be kept within 30 cm.
The microphone features a low-impedance balanced output via XLR male connector, using pin 2 and pin 3 for signal and pin 1 for ground (shield).
