K781 Intelligent conference mixer
K-781 is a microprocessor-controlled , automatic switching of 8 +8 channel intelligent conference mixer. It appeared ,
to small-scale international conferences ,from portable to mobile conferencing application provides a new application solutions.
K-781 intelligent conference mixer can be easily applied to all kinds of multimedia teaching and meeting PA ,
in the design office will fully take into account the actual needs of engineering applications. It has eight balanced
mic Caron and 8 -Phoenix wired balanced mic or line input channels and provide the required condenser
microphones 48V phantom power and a secondary unbalanced line inputs for external auxiliary audio access equipment.
Each input channel can be independently adjustable gain and built-in limiter , any microphone channel can be set according
to the actual needs of the Chairman of priority control channel , when the President of the microphone channel speakers for
the remaining channel's output level is automatically attenuated. Because each input channel has a built-in control circuit
threshold level can be adjusted to control the appropriate threshold values as needed. Can automatically turn on only the
signal input channels , which means that the entire course of the meeting , the meeting participants to adjust settings
without human speech microphone device can achieve a switch , chairman priority control function.
K-781 intelligent conference mixer built- NOMA feature that automatically adjusts the overall output level of the input signal
based on the number of channels , in other words, how the case supporting the microphone while speaking , the overall output
of the system to maintain a constant level , output gain will not be superimposed on the input level rises leaving the overall
system can effectively reduce the chance of " feedback sound " generated . This is the traditional way of reinforcement is rarely seen .
With this function , after debugging the system under normal sound conditions, without having to worry about the number of
microphones used simultaneously change caused unnecessary trouble whistle , especially in the small microphone multi- use
space in this environment a more prominent and useful features .
K-781 offers up to 15 cascade function, can use a temporary increase in the number of microphones based on actual usage,
can quickly and easily extend the size of the meeting to as many as 120 people , meeting mobility greatly enhanced.
In the small and medium sized conference room , lecture hall , VIP reception hall , conference centers and other places can adopt K781
intelligent conference mixer , to manage a large number of microphones, simplified operating system. Ensure its easy , efficient ,
safe and smooth conduct of intelligent messenger brings us is people-oriented technology fashion feel.
8 Caron balanced inputs, use a microphone or line-level signals (with adjustable EQ)
8 Phoenix head balanced inputs, use a microphone or line-level signals (with adjustable EQ)
2-way 6.35 inputs (with adjustable EQ)
2-way dual-channel music input (with adjustable EQ)
Each input provides independent 48V phantom power
Each input gain and volume controls provide independent
Each input attenuation level adjustable gates
Each microphone channel has compression limiter function
Each microphone channel can be independently switched to priority default mode
Can automatically turn on only the signal input channel, the sound level of the gate action can automatically adjust, easy to use.
Unique feedback suppression function, can adjust the gain for each input and output overall gain, in particular, can increase or
decrease based on the use of channels and automatically adjusts the output level, which can effectively prevent the whistle
15 units can be connected to K781, manage up to 120 conference microphone system
Different characteristics of different grades can be configured according to the actual situation of the microphone, connect easy to use and flexible
