Internal circuit with AGC gain control and power amplification
circuit, maximally eliminate the noise, to guarantee the output
intensity.
The
microphone is on the surface and restore sound more closely; hang tenon
type design of sliding block structure, easy to absorb the ceiling or
side wall installation.
Loud sound and pure timbre within 5-30m² monitoring range.
Audio pickup, designed for audio monitoring, the advantages of big monitoring range and high sensitivity.
Built-in
lightning protection, power supply polarity reverse connect
protection, ESD electrostatic protection and power protection module.
Long
audio signal transmission technology, Long audio signal transmission
technology, use the RVVP3 x 0.5mm² shield cable, it is distortion less
within 3km.
Integrated professional front audio amplifier circuit, direct drive active speakers, DVR, earphones, etc.
Applicable to the banks, factory, schools, offices and any places need to audio monitoring.
