Installation modedesktop

• It adopts digital technology as the core, with built-in high-performance CPU, and supports discussion and video tracking functions

• The audio signal is processed by 32bit high-speed floating-point DSP, with a bandwidth of 20Hz ~ 20kHz and perfect and clear sound quality

• The power supply will not be affected by the long switching distance and the sound quality will not be affected

• The anti-interference circuit is designed to eliminate the interference of all mobile phone signals

• It is equipped with 2.8-inch LCD screen and independent key operation

• USB / SD card MP3 recording and playback function, graphic display, Bluetooth playback, high fidelity wav and MP3 output. When not recording, it can be input as MP3 background music

• With four 8-core microphone connectors, each channel supports 30 units and can connect 120 units; With 4 RJ45 network interfaces, each channel supports 20 units, 80 units and 12 chairman units

• It supports cascading and facilitates the simultaneous use and common management of multiple systems

• It has s terminal and 5p terminal interface, connects standard definition or HD camera, and supports Sony visca, evi HD, PELCO P / D and brc300 communication protocols

• Built in 6-in 4-out (RCA interface) video recorder, up to 6 SD cameras can be connected

• With video switching RS-232 communication interface, it can be connected to HD video switcher

• It has an alarm signal input interface. When the public address alarm system is started, it can automatically suspend the meeting and send alarm information to the participating units

• With central control code RS-232 interface, it can be connected to the central control system

• Multi channel audio input and output interface, which can be connected to sound reinforcement or recording equipment. It has sound quality correction input interface return (unbalanced input) and sound quality correction output interface send (unbalanced output), which can be connected to external audio processor to further improve sound quality. It can also be connected to a wireless receiving device, and a wireless microphone can be used.

• The host and computer can connect and communicate through TCP / IP network or USB local mode, and use PC software to set the system. You can also set the system directly on the host without a computer

• There are many meeting modes: FIFO (first in first out mode), LIFO (last in first out mode), free (full open mode), c-only (Chairman mode)

• It can set the number of speeches, automatic closing, time limited closing, voice controlled speech and other functions

• It can be installed on 19 inch standard cabinet for easy storage and safekeeping
