Wireless Instrument Microphone for Stage Performance

The digital wireless audio transmission system features a frequency range that varies by region, allowing for flexible deployment in different geographic areas. The audio sampling mode is set at 48KHz, ensuring high-quality sound reproduction. The system offers 16 pre-set selectable frequencies, providing users with a range of options to choose from.

One of the key advantages of this system is its use of a digital ID code, which effectively eliminates any interference between frequencies. This feature is particularly useful in crowded performance environments, where multiple wireless devices may be in operation.

The system utilizes an IR (Infrared) sync function, which allows users to easily download the desired frequency from the receiver. This streamlines the setup process and ensures a seamless connection between the transmitter and receiver.

The power source for this system is a lithium battery, although the battery is not included in the package. This allows for portability and flexibility, as users can choose the battery that best suits their needs.

The receiver component of the system features the same 16 pre-set selectable channels, allowing for easy frequency selection. The modulation mode is pi/4 DQPSK, which provides a low latency of 92dB and a receiving sensitivity of -92dBm. The output is delivered through a 6.35mm plug, making it compatible with a wide range of audio equipment.

The transmitter component also uses the pi/4 DQPSK modulation mode, with a transmitter power of 10mW and a sensitivity of -47 db±2dB. The frequency change is facilitated by the IR synch feature, ensuring seamless integration with the receiver.

The transmitter utilizes a condenser microphone with a dimension of Φ14*5.0mm, providing high-quality audio capture. The power source is a 3.7V lithium battery, with a battery life of over 6 hours of continuous use.

The dimensions of the receiver and transmitter components are 1852010mm and 1254020mm, respectively, making them compact and portable. The operating range of the system is up to 40 meters in line-of-sight conditions, making it suitable for a variety of performance settings, such as saxophone stage performances and street performances.

In summary, this digital wireless audio transmission system offers a range of features and capabilities that make it well-suited for various performance and audio applications. With its pre-set frequencies, digital ID code, and IR synch functionality, the system provides a reliable and interference-free wireless audio solution.
