Wireless conference system host DH-9000

The system adopts the combination of digital and analog circuit, high fidelity circuit design, can produce high quality CD sound effect.

A maximum of 20 systems can be used simultaneously in the same environment, with each system supporting 199 delegates or one chair plus 198 delegates.

With first-in, first-out, chairman only, limited speech, limited speech function, with a button off function, allowing up to 4 units to speak at the same time.

Install the three antennas on the antenna connecting pegs on the back plate, and pull the antennas to a 45 degree Angle on the vertical line.

It can be connected to non-parallel mixed output socket: simultaneously output channel A and channel B audio signals.

In order to obtain good receiving effect, the receiver must be installed more than 1 meter above the ground, the distance between the transmitter and the receiving antenna is more than 2 meters, and the distance between the wall surface is more than 1 meter.

Keep the antenna away from interference sources, such as computer equipment, digital equipment, television, etc., as well as away from large metal objects.

Before opening the representative unit, make sure the volume of the power amplifier and mixer is set to the minimum.

The control antenna C and the audio antenna AB can not be mixed. Working distance of 60 m range.                                                                                             Carrier band UHF520-950MHz
