This is a professional GSM quadriband audio transmitter equipped with two stereo microphones. It's perfect for ambient locations such as vehicle or domestic room, remote unlimited audio surveillance. Equipped with two microphones for a perfect audio reception. The system allows to listen to ambient or vehicles from any distance. With its minimum size, it can be easily concealed in any vehicle or domestic environment, electrical outlets, switchboards, junction boxes or in small household appliances.
The transmitting audio is developed by a powerful DSP (digital signal processor) that reduces and eliminates noises and rustles whether in any environment. The firmware allows the complete real time management of sound. It's possible to modify remotely its algorithms parameters and also activate or not two independent Hi-pass and Low-pass filter.
They are available 2 otophone type microphones that can be selected individually or coupled with a "pseudo stereo" function that activates them both. It is possible to set up 2 programming thresholds of internal DSP to reduce noise in the cabin, for moving and stopping vehicles. Another special functionality is the “Dynamic Mik”, enables on board and external microphones to be switched automatically for example when the vehicle is stationary.
