    Rigging system description Elements for enclosure rigging On both sides, K2 integrates two arms to connect another element of the rigging system, such as an enclosure or to a ying frame. • At the front, a rotating arm provides a xed point around which the enclosure can freely rotate until its connection at the rear.

  • Page 20: Elements For Storage And Transportation

    Elements for storage and transportation K2-CHARIOT K2-CHARIOT is designed for the transportation and storage of blocks of four K2 enclosures. During transportation the blocks must have an inter-enclosure angle of 10° to avoid any separation of the enclosures. This angle must be set using the enclosure rear rigging arm pin. The automatic locking system must remain unloaded.

  • Page 22: Elements For Ying

    Elements for ying K2-BUMP K2-BUMP is designed for ying line arrays of K2, K1 or K1-SB. 4 holes are available on the central bar of the K2-BUMP. Refer to your Soundvision model to know which holes to use. With K1-SB and a single motor the hole n 2 provides a 0 site angle.
  • Page 23 By adding a K2-BAR to the K2-BUMP, the site angle range can be increased. 21 holes are available on the K2-BAR which can be attached to the K2-BUMP as a rear or a front extension and in position A or B, thus offering a total of 84 discrete positions for pick-up points.
  • Page 24 The K2-LINK is designed as an interface between the K1 and K2 rigging systems. It is used to hang K2 under K1, K1-SB or K1-BUMP. It provides three holes and therefore three angles between the top K2 enclosure and the bottom K1 element: 0.25°, 2.5° and 5°.
  • Page 25 The K2-RIGBAR can be used to implement a pullback either with K2-BUMP / K2-BAR or another K2-RIGBAR. It must be used with the LA-SLING2T. The K2-RIGBAR can also be used as the main lifting point, thus providing a lighter solution for ying K2 enclosures with one lifting point.

  • Page 26: Elements For La-Rak/La-Rak Ii Rigging

    Elements for LA-RAK/LA-RAK II rigging K2-RAKMOUNT The K2-RAKMOUNT is designed to stack one or two LA-RAK/LA-RAK II on top of a own array. It is composed of four rails and a stabilizer. The rails are screwed on the K2-BUMP. Their number and position depend on the number of racks. The K2-RAKMOUNT must be used along with either one or two K2-BAR.
  • Page 27 Rigging system description 1 LA-RAK/LA-RAK II : 2 rails : 2 K2-BAR 2 LA-RAK/LA-RAK II : 4 rails : 1 K2-BAR When two racks are mounted side by side, the stabilizer is used to prevent the assembly from tipping or toppling over.

  • Page 28: Mechanical Safety

    Always refer to Soundvision for the safety factor of a mixed array. When ying a K2 array with a Kara downll, the mechanical safety of all system elements must be considered. The indicated maximum limit applies to the K2 only.

  • Page 31: Loudspeaker ConGurations

    By providing the K1-SB with the same frequency response as the K2 low section, the [K1SB_X K2] preset allows the K1-SB enclosure to be used as an LF line source element, increasing the length of the sub-low line source.
