Characteristic
● COTT-C8 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.
● Adopt advanced flame-retardant resin ABS design, its internal resonance spoke after precise calculation, audio will be more clearly
● 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.
● Unique design of the "electronic noise dynamic closed-loop suppression circuit ", 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.
