The BOYA 3-in-1 Wireless Microphone with Onboard Recording, model BOYAMIC, is a portable 2.4GHz wireless microphone system designed for high-performance noise cancellation and versatile recording applications. It's suitable for improving recording quality in noisy environments and offers a remarkable onboard recording feature for storing recording files in real-time. This system is ideal for live streaming, vlogging, mobile journalism, and more, providing a low-cut filter to eliminate unwanted low-frequency noise (75Hz/150Hz or lower) in your recordings.
Function Description:
The BOYAMIC system consists of one receiver and two transmitters, offering a comprehensive solution for various audio recording needs. The transmitters feature built-in microphones and also support external 3.5mm TRS microphones or line-in devices, providing flexibility for different setups. The receiver is equipped with a 3.5mm TRS output, USB-C, and iOS Lightning adapters, allowing connection to cameras, mixers, smartphones, tablets, laptops, and computers. A USB-C charging port on the receiver supports charging and powering the device while using it with the adapters.
A key feature of the BOYAMIC is its onboard recording capability. Each transmitter has 8GB of internal memory, allowing up to 15 hours of recording at 48kHz/24bit sampling rate. Recording files are automatically split after 30 minutes and named in the format "DATE-TIME.-WAV". Up to 999 recording files can be created. This feature is particularly useful for backup or standalone recording.
The system incorporates advanced noise cancellation, which can be enabled or disabled via a dedicated button on the transmitter. It also includes a high-resolution OLED display on the receiver to provide vital information at a glance, such as channel A/B gain, output volume, wireless signal strength, and battery levels.
