The wide dynamic range processing technology modulates the audio signal and balances the processing of high and low audio. Features a high-sensitivity microphone using a omni-directional pickup pattern to provide clear, low interference audio. Built-in high-speed CPU, real-time processing of the audio signal with low latency.
