Functional

 

1、Four balanced inputs and eight balanced outputs, with stronger anti-interference ability. Four balanced inputs and eight balanced outputs, with stronger anti-interference ability;

 

2、Equipped with digital fiber coaxial input. It can be freely selected with three or four analog inputs or set to automatic selection mode;


3、The first and second analog inputs adopt a Line/Mic composite interface, which can be connected to the small signal of the microphone or the large signal of the mixer. At the same time, these two inputs are also sound sources for effect processing and are equipped with gain adjustment;

 

4、Quick mute button operation for input/output/music/microphone/effects, with precise level indicator light. Input with CLIP indicator light, output with LIMITED start indicator light;


5、All channels have first/second order all pass filters, parameter equalization, IIR frequency division, music channel has four stage FIR equalizers, and output channel has FIR frequency division;


6、Built-in full function echo and reverb processing function, capable of both karaoke and performance;


7、Fully functional mixing, each output can be routed to various inputs, echoes, and reverbs, and the amount of routing can be adjusted;


8、Pioneering external WIFI module box for wireless control, RS232 and drive free USB control interface, multifunctional infrared remote control;


9、Adopting a stable switching power supply design, it can be used normally in different voltage environments;
