    This message is presented when the specified array design exceeds the mechanical limits set by the JBL team for the speakers or selected accessories. Array designs that trigger this message should not be used under any conditions, as they can lead to hardware damage and/or injury.

  • Page 14: Rigging System Overview

    5 - RIGGING SYSTEM OVERVIEW SRX900 Series line array cabinets include an intuitive three-point rigging system. Angles are preselected while the system is still on the ground using the link bar, which extends vertically to the cabinet above. When an array is suspended, angles are locked using the stop pin.

  • Page 15: Angle Selection

    LINK BAR INDICATOR When selecting angles on a stack of SRX900 Series cabinets, always start at the top cabinet and work down to the lowest. Angles are selected while SRX900 Series cabinets are on the carts and resting on the ground. Since the rigging mechanism is not under load when the system is on the ground, the link bar can be moved freely to the desired position.

  • Page 16: Transportation

    6 - TRANSPORT A TION Each component in the SRX900 Series has a convenient and efficient transportation system. The SRX906LA and SRX910LA are both transported in stacks of four cabinets with their angles fully collapsed. The SRX906LA cabinets ride inside of a rugged road case and the SRX910LA cabinets travel on a vertical transport cart.

    Rigging Manual 6.1 INST ALLING CABINETS ON THE CASE OR VT Both the SRX9xxLA cabinets attach to their respective transport carts the same way, the following set of instructions is valid for both the SRX906LA with the SRX906LA Case as well as the SRX910LA with the SRX910LA VT. STEPS: •...
  • Page 18 Rigging Manual STEPS (Continued): • Prepare the next enclosure by setting the link bar to the 12˚ position, storing the stop pin in the handle, removing the link pin and the two front pins. • Lower the next SRX900LA cabinet onto the first enclosure and secure the two cabinets together at the front using the pins. •...

  • Page 19: Installing The Vt-Top

    Rigging Manual 6.2 INST ALLING THE VT -TOP The VT-TOP connects to the top cabinet of an SRX910LA stack to form a robust and defined footprint that stabilizes the carts during transportation. The flat top allows other gear to be stacked on top of SRX910LA arrays traveling on SRX910LA VT carts for a more efficient truck pack.

  • Page 20: Storing The Srx910La Vt

    Rigging Manual 6.3 STORING THE SRX910LA VT Once an SRX910LA stack has been deployed, the VT-TOP can attach to the SRX910LA VT for storage. Several carts can be stacked together for storage. STEPS: • Pin the rear attachment point of the VT-TOP into the storage position. •...

  • Page 23: Array Frames

    7 - ARRA Y FRAMES The SRX906LA and SRX910LA AF Array Frames are used for suspending SRX900 Series arrays. Although different in size, the two frames are functionally identical. The array frames were designed to work with single-point and front-back suspension methods. For single-point applications, the array frame can be used in conjunction with the VTX RC500 rotating clamp, allowing smaller arrays to be suspended from standard size trusses or pipes.

  • Page 24: Attaching The Extension Bar To The Spreader Bar

    Rigging Manual 7.2 A TT ACHING THE EXTENSION BAR TO THE SPREADER BAR The extension bar includes two pins for attaching to the spreader bar. An additional pin attached to the spreader bar is used in conjunc- tion with one of the pins attached to the extension bar to create the completed array frame assembly. STEPS: •...

  • Page 25: Array Frame Attachment Options

    The example below shows how the real and “virtual” positions are spaced across the extension bar. TIP: Refer to JBL Line Array Calculator 3 software to determine the best shackle position and attachment combination to achieve the required array angle.

  • Page 26: Extension Bar Positioning

    Rigging Manual 7.4 EXTENSION BAR POSITIONING When the extension bar is attached to the array frame in its normal orientation, it extends towards the rear of the array, permitting the maximum possible downtilt for the array. The extension bar also can be attached in a reversed position, which provides the maximum possible uptilt.

  • Page 39: The Srx900La Pb Pull-Back

    Rigging Manual 10 - THE SRX900LA PB PULL-BACK The SRX900LA PB is a pull-back attachment for configurations requiring a significant amount of downtilt. With the array frame connect- ed to the primary suspension point at the top of the array, the SRX900LA PB connects to the bottom of the array and is lifted by a second motor point at the rear of the array.

  • Page 40: When To Use A Pull-Back

    Rigging Manual 10.2 WHEN TO USE A PULL-BACK The use of a pull-back is common when the center of gravity (CoG) of an array falls outside the footprint of the array frame. Typically, long curved arrays with a large downtilt qualify for this condition. When this occurs, LAC-3 displays an error to indicate that the array frame alone cannot achieve the down angle needed for the design (Example 1 - No pull-back).

  • Page 41: Base Plates

    When not used with subwoofers, M10 through-holes can be used to permanently attach an array to other support structures. The base plates include one 50 mm wide (2 in) notch on each side for easy use with ratchet straps. Configurations and load conditions for using a Base Plate can be obtained using JBL’s LAC-3 software 11.1 BASE PLA TE OVERVIEW 2”...

  • Page 42: Base Plate Storage Position

    The base plate angle selection plate includes nine pin positions, allowing for a range of angles from -15 to +5 degrees in 2.5-degree steps. This facilitates selection of the most appropriate position for establishing the required array down angle. JBL Line Array Calculator 3 software is used to determine the best position and check array safety.

  • Page 43: Assembling Ground-Stacked Arrays

    The base plate connects to the subwoof- ers using the included M20 knob. SRX900 Series cabinets connect to the base plate using the cabinet’s front pins, and the link pin in the rear.
  • Page 44 Rigging Manual STEPS (Continued): • Remove the link pin and install the stop pin into the angle selection plate of the first SRX9xxLA cabinet. • Place the first SRX9xxLA cabinet onto the base plate and pin the front two corners using the attached pins. •...
  • Page 45 Rigging Manual STEPS (Continued): • Select the desired cabinet-to-cabinet angle for the first SRX9xxLA enclosure and extend the link bar to that angle. Pin the link bar with the angle selection pin in the corresponding hole of the angle selection plate. •...

    Rigging Manual 11.6 A TT ACHING THE BASE PLA TE ONTO A STRUCTURE The base plate can be permanently attached to a structure like a stage or platform using its three M10 through-holes. This is especially useful for permanent installations or other fixed applications where a ground-stacked SRX9xxLA system is needed, but not often moved. In such situations, the base plate is permanently attached to the structure and subwoofers are not used beneath the array.
