ECS-300 Series All-Digital Conference Host

Functions and Features

• Ergonomic, in line with IEC60914 international standards, embedded design, the use of simple alloy unit panel, beautiful appearance fashion.

• Can be customized according to the size of the opening of the conference table production for users to save trouble because of the wrong size of the desktop.

• Laser engraving of various badges and logos according to user requirements.

• With volume centralization in the host adjustment using professional audio processing design, so that the speaker’s voice clear and lucid.

• The unit is passive equipment, powered by the system host, low-power design, a single host can be connected to 150 conference units.

• The interference of electromagnetic wave to DIN wire can be effectively prevented by using 6-core tape to shield DIN wire.

• Low sensitivity to cell phone, can effectively resist cell phone interference.

• Electret super-heart-shaped directional microphone ensures sound pick-up distance and sound quality.

• Between the units with line live “hot swap” function, so that the security of the system get greater protection.

• The microphone lever can be removed between sessions for easy equipment maintenance. The microphone lever and keys are equipped with LED diaphragm, which can display the status of speaking, setting video, uncoded ID, etc.

• Designed with electrostatic isolation technology, static electricity can be avoided even in dry areas.

• The module supports six speech management models:

• Quantity limit mode, when the limit number of speakers is reached, other microphones cannot be turned on;

1. FIFO mode. When that limit numb of speakers is reach, if the microphone is turned on again, the microphone which is turned on first is automatically turned off,

• Voice-on mode, voice-on microphone;

• The request for the floor is approved or rejected by the Chairman’s unit of the system, which is set up as the Executive Chairman.

• With the Pan-Tai camera, after using the host or computer preset, the camera can be automatically tracked, supporting the camera linkage screen freezing function.

• It has the functions of check-in, voting, election, scoring, response and so on.

• The conference unit has its own DSP digital audio processing chip, which can adjust the high and low tones of each unit separately, and can adjust the gain of the specified microphone arbitrarily according to the field conditions, so as to meet the personal preference and adjust the pick-up distance.

• It has the function of restoring the factory value, and can initialize the audio adjustment to prevent the noise from being disturbed.
