Digital Video Conference System ZH-906

Product description:

ZH-906 conference system controller, with various conference modes for choice(number of speakers, and speaking modes). Strong extensions function, echo cancellation function, and Feedback eliminator function. Use equalizer to process the DSP sound.

Features and functions:

>. Using the high-end OMAP3530 processor from the TI of the United States, the Processing speeds is up to 1 GHZ

>. Built-in a 600MHz DSP processing Chips to suppress squeaking.

>. Using FPGA programmable logic device XC3S200A,run faster,and the system is more stable.

>. Built-in a 256MB-capacity DDR2 memory, and 1G large-capacity FLASH Memory;

>. Using the "high fidelity" PGA2311 digital audio processing chip;

>. Using 24bti/192KHz top-level ADC chip:AK5392,the dynamic range and signal-to-noise ratio are up to CD quality;

>. Four 24bit DSP parallelprocessing,dynamic range:116ZH,SNR:112ZH

>. Built-in shelf equalizer to optimize frequency response of the whole system.

>. Support seamlessintegration CMMAW technology and CCSEB Power Manager;

>. Can connect with 5000 microphones and 50 conference system expansion machines;

>. The power of the controller can support 130 microphones directly;

>. “hand in hand” connection, easy to install and maintain;

>. With audio input port,External audio signals like background music and telephone conference system are available;

>. Multiple audio output channels, can be connected to the PA amplifier to enlarge the speaker's voice,and also connect with recording system and telephone conference system;

>. With the function of restricting the speaking number:restrict the maximum speaking unit, the on-unit need to be off if you need to turn on other units when the speech unit reach a constant value. The speaking number can be adjusted, i.e. 1/2/4/6,no limitation for chairman unit.

>. First in and first out function:If the current number of speakers has reached to the maximum value, the new open microphone will replace the earliest open microphone automatically. The amount of speaking unit can be adjusted by 1/2/4/6,no restrict of chairman unit.;

>. Built-in equalizer, can adjust the audio signals to meet the needs of different auditory;

>. Built-in digital frequency shifter to restrain the howling effectively.

>. Cooperate with the central control system can realize unified management of conference system;

>. Voting function and data management function;

>. Support remote teleconference with telephonecoupler.
