    Preface This manual contains all the information that is necessary to prepare and plan the installation of the mixing console and accessory components. Please, read this manual carefully. We point out common mistakes and problems that are connected with the installation and provide suggestions to avoid such problems.

    1. Power supply 1.1 Power supply units unit UPS10 is used. In addition, the UPS25 of the 5MT series of Three different power supply units are available, the UPS1000, consoles can be adapted since all the required voltages are the UPS10 and UPS25.

    240 V with the 230 V version and in steps of 5 V from 100 to 120 V with ab Werk normalerweise auf 230 V geklemmt the 115 V version. The minimum mains voltage depends on this settings. 240V...

    For fail-safe operation a second, identical power supply and an additional cover plate, take care that the distance between the top of the unit and crossover device are used. See the chapter below for details. the additional cover plate is at least 5 cm / 2”.
  • Page 7 The terminals for the primary voltage settings are clearly marked inside is eventually the same, as it depends not on the capacity of the power the power supply unit either on the mains transformer for the UPS1000 supply unit but the current consumption of the console.
  • Page 8: Fail-Safe Power Supply

    C1750 cross over units are equipped with Shottky diodes mains voltage too, is much too high. This results in a high voltage across with very low drop out voltage to keep voltage drop and power the voltage regulator, therefore in a high power that causes higher heat dissipation of the failsafe system as low as possible.

    1.4 The Mains Power Supply of Audio Systems conditions. Additional ventilation is not required and the installation is not critical as far as the airflow is concerned. Connectors ONLY QUALIFIED PERSONNEL SHOULD BE ALLOWED TO INSTALL All connectors are mounted on the rear panel of the device. The mains AND/OR MODIFY HAZARDOUS VOLTAGE, ELECTRICAL SYSTEMS.

Even though the input filters of the console’s power supply of these considerations is that a separate, current free conductor must units and an additional, totally separated screen winding of the mains be used for ground. If the mains supply line is implemented as a five-line transformer will block these disturbances as far as the console’s DC supply...
  • Page 11 This principle should be used to connect the electric ground and protective allows easier control over the power dissipation but it produces high- ground of all devices in the studio with high cross section cable.

    Inrush current Cable length Since the power supply units of the SRC51 consoles have a very high The cables that are usually used are high cross section multicore cables inrush current, precautions are necessary that concern the mains fuses.

    In this case, we use an AUDIO POWER CONNECTORS IN CONSOLE, additional connector for the two high current audio lines only. Using a 26 line / 1.5 mm2 cable means that 6 1.5 mm2 lines can be used POWER-SUPPLY AND CROSS-OVER UNITS for the 4 high current audio lines in parallel.

    For the realization, the main ground node, which in this case can be the Video central ground point of the building, or a separate earthing electrode, or This is the basic problem of any TV studio. Since all video connections are...

    There is only one possible way to deal with these problems. After the the skin depth is approx. 0.3 mm. With audio cables that usually have a installation is ready, tested and clean, check if there is any degradation diameter in the range of 0.2 to 0.4 mm this means, that there is simply...
