  • Page 25: Rigging System Description

    The L2 system includes two enclosures: L2 and L2D. Each enclosure can be flown or stacked alone, or assembled into a flown array. The coverage of the array is achieved by the 10° curvature of the L2 enclosures, while the 60° curvature of L2D is designed to make it the last enclosure at the bottom of the array.
  • Page 26 The rigging elements and latches are fitted with yellow safety labels that are visible when they are not safely locked. On both enclosures, seven inserts on each side provide further options such as flying with L2-RIGBAR as the main or pullback accessory, stacking on L2-CHARIOT/L2D-CHARIOT, securing L2-LASERMOUNT or L2-ROLL.
  • Page 27 Rigging system description L2 features four ground runners on the bottom, and both L2 and L2D feature matching tracks on the top. Two ergonomic handles on each side of the enclosures are available for handling. Dedicated chariots for L2/L2D L2 is intended for use only with L-Acoustics L2-CHARIOT.

    L2-BUMP is a rigging frame designed for flying L2 and L2D. L2-BUMP can be used as the main lifting accessory for flying arrays of L2 with L2D, or a single L2D using the included two Ø19 mm shackles WLL 3.25 t and extension sling.
  • Page 30 Front Rear To increase the site angle, four additional holes are available to add one L2-BAR on the central bar or two on each side bar. L2-BUMP is compatible with LA-RAKMOUNT to secure a single LA-RAK III above the array. Refer to LA-RAKMOUNT (p.35).

  • Page 31: L2-Bar

    By adding L2-BAR to L2-BUMP, the site angle range can be increased. Seventeen holes are available on L2-BAR, which can be attached to L2-BUMP as a rear or a front extension and in position A or B, thus offering a total of 68 discrete positions for pickup points.

  • Page 32: L2-Rigbar

    L2-RIGBAR Secured at the bottom of the array using two ball-locking pins, L2-RIGBAR can be used as a pullback either with L2- BUMP combined with L2-BAR or another L2-RIGBAR as the main lifting accessory, to provide a lightweight solution for flying an L2 array.

    Mechanical safety Mechanical safety Flown configurations The L2 rigging system complies with 2006/42/EC: Machinery Directive. It has been designed following the guidelines of BGV-C1. 2006/42/EC: Machinery Directive specifies a safety factor of 4 against the rupture. The flown deployments described in this manual achieve a safety factor of 4 or more.

  • Page 50: Assessing Mechanical Safety

    Soundvision calculations are based on usual environmental conditions. A higher safety factor is recommended with factors such as extreme high or low temperatures, strong wind, prolonged exposition to salt water, etc. Always consult a rigging specialist to adopt safety practices adapted to such a situation.

  • Page 51: Loudspeaker Configurations

    Loudspeaker configurations Line source Deployed as a line source, the system operates over the nominal bandwidth of the L2/L2D enclosure, with an adjustable horizontal directivity. All presets allow for a reference frequency response in long throw applications. Three configurations are possible : L2 line source, L2D line source, or L2/L2D line source.

  • Page 52: Line Source With Low-Frequency Element

    Loudspeaker configurations Line source with low-frequency element A L2/L2D line source can be deployed with additional subwoofer enclosures to extend the bandwidth in the low-end or increase sub-low resources.
