About the supplied audio-video presentation system
A 110“ video wall featuring 4 professional Hyundai D55LFB LED monitors in a 2x2 configuration was delivered. Each monitor is 55", each has HD resolution and 500 nits of illumination while the bezel is only 3.5mm. The video wall is mounted on a stand-up rack.
Video signal distribution is done via the HDBaseT HDMI Extender Aten VE812 with which it is possible to transmit a 4K signal without loss to a distance of 100m via a single CAT6 network cable. HDMI signals from different video sources are distributed through the system via a 4K switcher 4/1 Aten VS481B.
The de-embedder Aten VE880 is in charge of issuing audio signals from the HDMI signal.
In addition, the professional Sony FW-65XE8501 65" diagonal monitors placed on Edbak TR4 wheel stands are placed in two separate meeting rooms. The transmission of the HDMI signal between the laptop on the desk and the monitor is done via the wireless HDMI Extender Aten VE809 which transmits the HD video signal to a distance of 30m without any disturbances.
The central part of the audio system is an audio matrix XILICA U1608-AEC – a digital DSP audio processor with 8 inputs/16 outputs and an AEC algorithm for echo suppression in the audio system. Part of the audio conference system also consists of the Audix MicroPod gooseneck microphone, 30cm long with cardioid pattern. These microphones are specially designed for presentations and meetings due to their immunity to RF interruptions that are commonly present in meeting rooms as a result of the radiation of mobile devices. The rest of the audio system consists of an RCF MA-125 amplifier and a built-in RCF PL 6X coaxial ceiling speaker.
