UHF Four Channels infrared Wireless Microphone System

タイトルまたは説明

Key Features:

 * Use UHF******0MHz 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 *0 meters with more than *0 meters away from the ideal use of space.
