Description

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.

The system can pick up sound through building walls, ceilings, floors, etc. An external sensor is connected to an audio amplifier that provides tactile volume control on the left and right channels, as well as external USB flash drive recording. It is the leader of the same kind of products by providing accurate, sensitive and high-definition listening effect and recording year and time. It can be heard through buildings such as walls, roofs and floors, as in places where hostages are being held.

It can not only be used as the special forces rapid monitoring equipment, but also, criminal investigation, technical investigation departments of the investigation and anti-reconnaissance of the necessary products.

Features

1. Built-in powerful DSP sound algorithm processing, to ensure the best monitoring sound quality.

2. 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.

3. With professional audio sensors, channel 1 or channel 2, or both listening.

4. After DSP processing output, two channels can be simultaneously recorded.

5. Monitoring mode: wired headset, wireless Bluetooth headset, recording.
