Built-in powerful DSP sound algorithm processing, Audio Multifunctional Stereo Listening System Low Noise
Multifunctional stereo audio system can receive and record analog sound signals (human voice, footsteps, other sounds). Due to the adoption of reflective low-noise DSP processing and amplification equipment, the signal is picked up by the left and right independent stereo sensors in the front end, and output after demodulation by the control processing unit in the back end, so the machine can detect very small sounds.
l Built-in powerful DSP sound algorithm processing, to ensure the best monitoring sound quality.
l Customized professional partition audio sensor, shock sensor transmission vibration through very low noise amplifier +DSP processing, even very weak sound signal can also be heard.
l With professional audio sensors, channel 1 or channel 2, or both listening.
l After DSP processing output, two channels can be simultaneously recorded.
l Monitoring mode: wired headset, wireless Bluetooth headset, recording.
l Professional and personalized touch + vibration operation.
