User manual AKG HUB 4000

[. . . ] Please note that the equipment will not be fully isolated from power when you set the power switch to OFF. Do not place the equipment near heat sources such as radiators, heating ducts, or amplifiers, etc. And do not expose it to direct sunlight, excessive dust, moisture, rain, mechanical vibrations, or shock. To avoid hum or interference, route all audio lines, particularly those connected to the microphone inputs, away from power lines of any type. [. . . ] Each LED indicates the following conditions: LED flashing: Data is being exchanged between the assigned data port on the HUB 4000 and the connected SR 4000 receiver. Once every 3 seconds): There is a communication problem between the assigned data port on the HUB 4000 and the connected SR 4000 receiver (hard or software error, defective data cable, etc. ADR: Located beneath the cover with the AKG logo is a bank of four DIP switches for setting the IP address of the HUB 4000. The connecting cable is not supplied with the unit. To connect the unit directly to a computer, use a crossover Ethernet cable. To connect the unit to a standard Ethernet hub, use a straight-through Ethernet cable. Operate the equipment with the included power supply with an output voltage of 12 VDC, 500 mA only. Using adapters with an AC output and/or a different output voltage may cause serious damage to the unit. Prior to setting up the unit, check that the AC mains voltage stated on the included power supply is identical to the AC mains voltage available where you will use your system. Using the power supply with a different AC voltage may cause damage to the unit. ) A single HUB 4000 allows you to control up to eight SR 4000 receivers from a computer. You can use one or more commercial Ethernet hubs to daisy-chain several HUB 4000s and control the entire setup from the computer. The number of receivers you can actually control on your computer will ultimately depend on the size and resolution of your monitor. Plug a straight-throughEthernet cable into the PC LINK socket of each HUB 4000. Plug the other end of each network cable to an unused output on (one of) your Ethernet hub(s). Be sure not to use any cables other than the supplied data cables with RJ 11 connectors. Each unit within the network needs its own, unambiguous IP address. â· The IP address of each HUB 4000 is factory-set to 192. Before connecting the unit to power, check that the IP address (ADR combination) of the unit is not identical to any other IP address previously assigned within the network. iP addresses assigned to multiple units may cause data transmission problems. If you daisy-chain several HUB 4000s, remember to assign to the hubs consecutive IP addresses in ascending order to make sure the computer will correctly identify and control all HUB 4000s. â· You may assign any IP address between 192. [. . . ] Connect power supply to HUB 4000 and/or power outlet. Should the problem persist, contact your nearest AKG Service Center. â· Switch unit OFF, wait for 10 seconds, switch unit back ON. Should the problem persist, contact your nearest AKG Service Center. [. . . ]
