  • Page 9: Storage And Transportation

    1.3 Storage and Transportation Please note the following: The device should only be transported on its dedicated transport dolly or wheelboard. Store the device in a dry environment, with a constant ambient temperature, in order to avoid condensation. The permitted ambient temperature range for storing the device is -10 °C to +70 °C. Due to fluctuations in temperature during transportation and storage, condensation may start to build up on the surface of the device.

    Each Focus Venue module has four suspension points at the top, each equipped with a recessible steel latch and four respective slots for suspending further FV-modules at the bottom. The Fohhn ILS rigging system connects latch and slot. It is spring-loaded, self-securing, easy to use and without any loose parts like ball lock pins on steel cords.
  • Page 18 To move the latch, a knurled-head screw acts as a handle and may be tightened as soon as the latch is connected to the above rigging pin to avoid rattling noise at high SPL of the system. A yellow tag on the latch indicates, that the latch is not connected to the respective slot in the upper module or flying frame.

    FV-100 and FV-200. If an FV-100 downfill adapter or a pull back frame/downfill adapter with Fohhn PT-70 or other fill systems is added, the number of cabinets has to be reduced accordingly.
  • Page 20 Danger! Please note: Make sure all four latches of the top module are at the upper stop (no yellow tag visible) and all four rigging pins are pushed through the frame, their ball bearings visible! Otherwise it is not safe to hoist the system!
  • Page 21 To rig the system, take the rigging skids out of their parking position and insert them into the central suspension rail. Again, make sure the quick release pins are safely assembled, their ball bearings protruding on the opposite side of the rail. Warning! If any other shackle than the supplied one is used, be aware that the WLL must not be less than 4,75 tons at a safety factor of at least 6!

    If a downfill spaker with TV-spigot is flown below the Focus Venue, the inclination angle is limited to 25° towards vertical position. 4. A straight array of up to four (4) Focus Venue modules may be inclined front-to back downwards or upwards in a maximum angle of 40° towards vertical position, a pull back frame/downfill adapter is required.

    Lift off the cover from the cabinets and store it safely. 2. Connect each Focus Venue module to Fohhn Audio Soft and check its Fohhn-Net ID.
  • Page 25 Fohhn-Net ID. This can be removed before the system is actually flown. Further information on allocating and changing ID numbers can be found in chapter 4.5 as well as in the Fohhn Audio Soft user manual. This can be downloaded free of charge from our website: www.fohhn.com It may also be helpful to put together a brief overview of all integrated Fohhn-Net devices, along with their respective ID numbers.
  • Page 26 To secure the system correctly, please pay careful attention to the “Safety Chains” section (3.2.3). 6. Connect the system to its supply cables for mains power, network (Fohhn-Net) and audio signal. (For details on this, please refer to chapter 4) All cables have to be of sufficient length to form a loop.
  • Page 27 At this point, there are two different possibilities of setting the mains power switch, depending on how the array is wired. Please refer to chapter 4.1 and 4.2 7. Raise the flying frame and the top module to a suitable height that enables you to position the second module below it.
  • Page 28 9. Lower the upper module onto the lower one. The latches will guide them into correct position. Please note the following: a. There shouldn´t be any gap between the two modules. Danger! b. Stop the motor as soon as the chain loses its tension! Otherwise there is a risk for longer arrays to tilt and tip over! c.

    3.2.5 Landing an array Landing the system is basically done in reverse order. Therefore, please observe the following: Danger! • Make sure the floor is suitable to bear the weight of the entire array, flat and even. If you have to work on sloping terrain, it could get hard to disengage the ILS between the modules and you have to take extra care to prevent the dolly from moving.

Tilt the lid outwards then fasten the velcro on each side. Always make sure the air entrance (bottom panel) and outlet (top panel) are not blocked by the rain cover! The velcro has to be fastened as shown below, otherwise the system is likely to overheat and switch off.

    3.4 Rain hood for the top of an array Since Focus Venue is an active system with built-in electronics, we recommend for its outdoor use to protect each stack or array by a rain hood. Though each module in combination with two rain covers for the connector panels is weatherproof up to a certain degree, in the long run an array may suffer from heavy rain or snow.
