    K7100 Digital

    Product Scope:

    Frequency shift general education classrooms amplifier is specifically tailored for the complete 

    set of professional sound reinforcement equipment ,but also to satisfy the courts and agencies, 

    military units , enterprises and institutions use the conference room sound , with a high cost .

     Against the small particularity in public places , which focus on solving the sound stability , 

    sensitivity and sound clarity of these three problems , effectively suppressing acoustic feedback , 

    significantly attenuated the microphone whistle, to ensure high-quality sound effects.

     

    1 , comprising 24Bit A / D, D / A converter ; 24 DSP processor , 48KHz high-speed sampling .

    2, the four parameters filters and DSP digital frequency shift feedback inhibition composition ;

    3 , six mic inputs , MIC1-MIC4 with 48V phantom power. ( 1-4 with four microphones choose a function )

    4 people acoustic excitation function, can enhance speech intelligibility .

    5 , built-in limiter , automatic dynamic control .

    6 , four parametric equalizer , can absorb four notches

    7 , automatic protection , automatic gain , dynamic protection .

    8 , four line inputs ( can be accessed by computers , DVD , etc. ) , Road recording level output

    9 , will be hindered constant voltage output selectable (2 × 100W impedance output , 120W constant voltage output )

    11 , microphone volume / music volume and adjust machine parameters figures , and computer remote control 

    (supplied PC software control )

    12. Panel buttons can be locked to prevent misuse of students
