Product Overview

  • COTT-C7 Designed for public security organs industry of synchronous monitoring audio recording.
  • Using UniGuard radio-frequency interference (RFI) shielding technology, prevent radio-frequency interference, inhibit noise from surrounding environment.
  • Using the micro hole design of "temple of heaven echo wall" principle, precisely calculate sound reflection angle to reach the best.
  • Using the echo to eliminate concave cavity,effectively reduce serious echo of an empty room, provide clear and high quality audio signal output.
  • Using dolby directional logic surround sound system, built in high-speed voice processing units, two level dynamic noise reduction processing.
  • KaBoni gold plated vibrate film capacitor microphones, 10-150㎡ in high fidelity, high sensitivity and low noise.
  • Built-in AGC and DTS noise reduction signal micro processing circuit, automatically adjust the high strength and instantaneous impact sound.
  • Built-in newest DNP and DSP digital processing unit, completely eliminate "hiss" electronic noise.
  • Built-in lightning protection, power supply polarity reverse connect protection, ESD protection and power protection module.
  • Long audio signal transmission technology, use the RVVP3 x 0.5mm2 shield cable, it is distortionless within 3km.
  • Applies to -25℃~70℃ in the super environmental temperature, to ensure the quality of the back-end high recording effect.
  • Integrated professional front audio amplifier circuit, direct drive active speakers, DVR, earphone, etc.
  • Applicable to public security organs interrogation room, tender center, school classroom and other indoor enviroment of synchronous monitoring audio recording.
