Cooperate with SU SU - 5000-5900 can form a wireless video automatic tracking system Introduction to the This product is a 4 channel mixer, wireless meeting by four wireless conference microphone and 1 with mixer function of the receiving host. Work in the UHF frequency band, the high frequency circuit: the PLL phase-locked loop control oscillation, audio lock code recognition technology. Can automatically search without disturbing frequency point automatically after wireless data of frequency technology, effectively avoid interference! Audio circuit: using high-performance dynamic extension and intelligent mixing circuit! Restore the real signal! Machine is also equipped with RS - 232 control interface, convenient and communicate with central control, wireless video automatic tracking function. The characteristics of S 800-866 MHZ operating frequency, away from the source spectrum. S microprocessor controlled PLL phase-locked loop frequency synthesis technology, precise automatic search no interference frequency point. S multiple work frequency band design, support more than one machine extension use! S use multilevel high frequency amplifying circuit and the second difference frequency receiving circuit, uninterrupted receive clear voice. S each receiver, the volume can be adjust alone and can be set to priority to speak! Light touch type electronic switch design, automatic eliminate the impact of noise. When the switch intelligent mixer automatically choose to speak in microphone signal output, effectively prevent the generation of noise! S professional audio output design, 4 way before the XLR output plus smart mixing output and 4-way set output! S wireless data on the frequency and control technology, wireless data used with control to realize intelligent control. S used SMT SMD assembly process and standard components, ensure the reliability. S can be used at the same time 5 sets of 20 receiver Technical parameters Transmitter part: S frequency characteristic: 40 hz - 18 KHZ S oscillation mode: PLL S transmission power: 3 mw S effective distance: 50 m S microphone directivity: super cardioid S largest input pressure: 100 db SPL S signal-to-noise ratio: 86 db S distortion: < 0.6% S modulation mode: FM S battery specification: 1.5 V 5 x 2 day S frequency stability: + / - 5 PPM S microphone sensitivity: - 35 db S carrier frequency range: 700-866 MHZ S current consumption: 170 ma S temperature range of use: 10 ° C to + 45 ° C S receiver rod length: 38 cm S weight: 0.8 Kg Receiver: S frequently ring tone: 40 hz - 18 KHZ S oscillation mode: PLL S signal-to-noise ratio: 86 db S distortion: < 0.6% S modulation mode: FM S frequency stability: + / - 5 PPM S carrier frequency range: 800-866 MHZ S temperature range of use: - 10 ° C to + 45 ° C S size: 235 * 434 * 44 mm S weight: 4.2 Kg of material Before noil channel output level and impedance: - 14 DBV 75 Ω (Max) S set output level and impedance: + 3 DBV 330 Ω (Max) S mixing output level and impedance: + 0 DBV 75 Ω (Max) S power: AC220V 13 w S product standards: Gb13837 Gb8898
