10 1.2 Functions and features Based on TAIDEN originated diratc-digital infrared Audio Transmitting and Control technologies Digital infrared audio processing and transmitting technologies ensure superb sound quality: Freq. Response: 20 Hz to 20 khz S/N: >85 dba THD: <0.06% IR transmission technology, no worries about eavesdropping and radio interference, no RF radiation Privacy guaranteed by infrared transmission Unlimited quantity of infrared wireless conference systems within a building Easy to setup, move and remove, no wiring or drilling, perfect solution for historic venues Thanks to tabletop installation and ceiling reflection, especially suitable for small to medium-sized conference rooms with a light-colored ceiling not exceeding 5 meters Audio, control and power signals all transmitted over a single Cat.5 cable from the highly-integrated main unit with infrared receiver and a built-in digital signal processor Adopts 1~6 MHz transmission frequency, undisturbed by HF driven light sources IR coverage >8 m radius (4 m high ceiling) Excellent immunity to RF interference from mobile phones and RF devices Discussion and automatic video tracking 3

11 1.3 System technology Basic system concept The system composition of one digital infrared wireless conference combo unit, one digital audio power amplifier and digital infrared wireless conference units: The digital infrared wireless conference combo unit receives infrared signals from every digital infrared wireless conference unit and converts the signals into audio which is transmitted to the digital audio power amplifier, or into control signals which are convert into carrier outputs and transmitted to the digital infrared conference units. transmission of infrared light. This can be solved by using a sufficient quantity of transceivers. They should be positioned in a manner to provide an infrared field strong enough to cover the whole conference area Carriers and channels TAIDEN HCS-5335 compact digital infrared wireless conference system adopts 1~6 MHz wave band (IEC BAND Ⅲ,Ⅳ), shown as figure And the Channels and corresponding frequencies refer to table IR radiation Audio and control signals of HCS-5335 are transmitted as modulated infrared light. Infrared radiation is part of the electro-magnetic spectrum, which is composed of visible light, radio waves and other types of radiation. Its wavelength is longer in comparison with the wavelength of visible light. Infrared light cannot pass through opaque walls and ceilings and therefore guarantees privacy of the meeting by avoiding of being intercepted or disturbed. In addition, infrared light has no radio radiation and a license is not required when operating infrared light systems Aspects of infrared signal transmission Just like visible light, infrared radiation is reflected from hard surfaces and refracted by hyaloid (glassy or transparent appearance) items. Objects in the conference venue as well as structure of the walls and ceilings will influence the distribution of infrared light. Infrared radiation is reflected from almost all hard surfaces. Smooth, bright or shiny surfaces reflect well. Dark or rough surfaces absorb a large part of the infrared energy. Usually, surfaces opaque to visible light are also opaque to infrared radiation. Shadows from walls and furniture will influence the Figure 1.2 Standard wave band in HCS-5335 system Route Channel Frequency From conference Audio channel MHz unit(s) to combo Audio channel MHz unit Control channel 2.8 MHz From combo unit to conference unit(s) Control signal 3.3 MHz Table 1.1 Channels and corresponding frequencies in HCS-5335 system 4

12 Chapter 2 Digital IR Wireless Conference System Combo Unit 2.1 Overview HCS-5335M Compact Digital Infrared Wireless Conference System Combo Unit is the heart of the HCS-5335 wireless conference system.
