Product Details

Model: AF300

A: Features

1. Adopting an adaptive environment howling suppression algorithm, utilizing a high-speed floating-point digital audio processor and advanced sub-band denoising technology, it can quickly and automatically eliminate chirping and background noise.

2. The fully automated operation mode eliminates manual debugging, and the system installation does not require sound field debugging. The functions are plug and play, shortening the installation and debugging time of the project.

3. Built in 24 bit A/D and D/A conversion; 32-bit 96K sampling high-speed DSP processor. Intelligent dynamic automatic gain matching technology improves the pickup distance and obtains clear, continuous and stable speech signals

4. Intelligent dynamic environment noise reduction technology can filter out background noise in the on-site environment without affecting the high-quality transmission of voice signals. Improve signal-to-noise ratio, enhance sound quality 5, with automatic mixing function. When two inputs are made simultaneously, the system automatically balances the gain.

6. Each microphone is independently controlled by a 48V phantom power supply.

7. 2.0-inch TFT color screen, displaying functional status and signal status.
