● 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.
