Built-in powerful DSP sound algorithm processing, Audio
Multifunctional Stereo Listening System Low Noise
Model: HWCW-V
Description
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.
Features
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.
