Eight channels wirelss meeting/conference/gooseneck/desktop microphone

systems

Key Features:

 * Use UHF710-980MHz band PLL frequency synthesizer PLL applications,

frequency adjustable, can use multiple sets of interference.

 * Integrated total control of the central processing unit CPU, the

interface with the digital LCD display, easy operation and outstanding

performance.

 * multi-level narrowband frequency filtering high-frequency and

frequency selection, fully eliminate the interference signal.

 * expansion of audio compression technology used, noise greatly

reduced, dynamic range increased.

 * whistle suppression transfusion has decreased function, can

effectively reduce transfusion whistle.

 * multi-level high-frequency receiver amplification, with high

sensitivity.

 * Multiple noise monitoring circuit, the ad hoc system of mono lock

TONE-LOCKED, so that interference with unparalleled features.

 * Use good chips and quality components, so that the excellent quality

of the machine.

 * Kongkuo maximum distance of 60 meters with more than 30 meters away

from the ideal use of space.
