Seite 3 dwcs2.4 Digital Wireless Conference System System Description dwcs2.4 is a new wireless conference system, developed by „IRP professional sound products", which operates in the 2,4GHz range. The data and audio transfer is full digital and all audio signals are digitally encoded. The changing digital signal encoding makes an unwanted hearing of the spoken words practically not possibly. (hearing security is the fundamental problem of all wireless conference systems, since these units use the UHF analog audio transmission. With an accordingly equipped UHF device it is easily possible to receive the discussions of a confidential conference in a neighbouring space.) A further considerable advantage is the circumstance that the signal transmission is licence-free in the 2,4GHz range. Thus a local installation or a mobile system used at different locations is very simplified. The installation and the operation of the devices are comparatively simple. Except the connections of the antennas and the power cord no further cables are necessary. The installation of the two antennas is also likewise problem-free and easy. The microphone stations are carried in a special carrying case with integrated battery charger and are immediately ready for use. Front View of the Main Unit Changes to improve the design or performance are reserved. Seite 4 Being connected to the world is NOT always what you want .. the dwcs2.4 with digital encoding gives you full privacy when you need it! 100% Privacy - Licence-free Seite 5 FCC Certification This equipment has been tested and found comply with the limits for class A digital device, pursuant to Part 15 of the FCC rules. Seite 6 CE Seite 7 Possible System and Delivery Configurations A: one Mainframe, one Audio Board, one Controller Board, one Antenna Splitter Board 2x 1in4, seven SMA Antenna Patch Cables (prewired), one Controller Patch Cable (prewired), two Antenna Cables (N-Steckverbinder), two Antenna Cable Adapters (N-Connector to SMA Connector) for furniture installation, two Antennas 2,4GHz (SMA-Connector), the appropriate number of regular Microphone Stations, one Chairman Microphone Station, one (two) Carrying Cases with integrated battery charger (12 Microphone Stations each, two cases combined to one carrying and changer unit). B: two Mainframes, two Audio Boards, one Controller Board, two Antenna Splitter Boards 1x 1in8, one blind panel, eleven SMA-Antenna Patch Cables (prewired), two Controller Patch Cables (prewired), two Antenna Cables (N-Connector), two Antenna Cable Adapters (N-Connector to SMA-Connector) for furniture installation two Antennas 2,4GHz (SMA-Connector), the appropriate number of regular Microphone Stations, one Chairman Microphone Station, one (two) Carrying Cases with integrated battery charger (12 Microphone Stations each, two cases combined to one carrying and changer unit). C: the appropriate number of Microphone Stations as single units, single Battery Chargers for the Microphone Stations (no carrying case with integrated battery charger), one or two Mainframes inclusive Boards, Cabling and Antennas as described above. Seite 8 System Setup 1. Scope of Supply Before the installation, insure that all accessories were completely supplied. If something from the scope of supply is missing, please call your dealer. 2. Battery Charger (Microphone Stations) All microphone stations should be fully charged before the first use. Depending on the scope of supply, use the carrying case with integrated charger unit or the individual battery charger. Using the carrying case with integrated charger the following is to be considered: All microphone stations should be locked in their position in the foam material inserted. Check the fixed position of the microphone stations. With appropiate fixing to the foam material insert a safe contacting to the charge connector is ensured. If you have a double carrying case for 24 microphone stations, connect both parts with the supplied connection cable. Connect the power connection cord to the appropriate wall outlet. The charging time is about 3.5 hours. The integrated battery is a NiMH and doesn’t require complete unloading before the new charging. 3. Checking the individual Boards and Cabling of the Main Frame Depending upon delivery version, all boards should be installed ito the mainframe and connected completely. If necessary check the wiring. See figure “Module Wiring” on page ... Check all connectors for tight connection and mechanical stability. NOTE: the radio net address of the system and the radio channel number of the radio circuits are factory-installed. If you should use several systems in the same environment at the same time, it is necessary to change the radio net address. Thus it is prevented that the systems influence each other. Both the audio board and the microphone stations must be modified. These procedures should…
