HAP301
Hi-fidelity Pickup
>Â Designed with a high-sensitivity omnidirectional microphone which picks up clear sounds and has a high anti-interference capability.Â
>Â Built-in CPU audio capture module with reduced hardware circuit interference and audio noise.Â
>Â Offers WDR technology which increases the range of audio signals that can be received, and allows the system to process large and small audio signals.Â
>Â Comes with a high-speed DSP digital information processor that helps improve signal clarity and prevent the distortion and attenuation of voice signals.Â
>Â Built-in high-speed CPU that processes audio signals in real time with low latency.Â
>Â Protects against lightning, reverse polarity and electrostatic shocks.Â
