6. further information on ground stack techniques X BOW components can be used to stabilise ground stacks and also to ensure that cabinets remain securely registered to each other where it is desirable to angle cabinets within a groundstack In the example shown here an M3 cabinet stacked on a B1 cabinet has been angled upward by 6 The X HINGE ensures that the rear of the cabinets are safely connected together and provides the correct pivot point for the M3 The vertical angle is achieved by placing a block of timber between the cabinets at the front edge The thickness of the spacer determines the vertical an gle providing an increase of 2 per 25mm spacer The timber spacers can be reliably secured using Velcro Strips Grouno Stacks ano SAFETY Statistically many more injuries occur due to unstable ground stacked PA systems than those associated with flown systems There are several reasons for this fact however the message is clear Always survey the supporting structure upon which a ground stack is to be built Always look beneath PA wings to inspect the deck support and if necessary ask that stage scrims and dressings be removed to allow access If the stage surface slopes as it does in some theatres ensure that the system is prevented from sliding forwards due to vibration This may require the fitting of timber battens to the stage surface For outdoor systems ensure that the system is protected from wind forc

8. Thank you for purchasing X BOW the integrated flying system designed especially for the Nexo Alpha Series of loudspeaker cabinets The design of X BOW has been optimised for the dispersion characteristics of the Alpha Loud speaker Family and enables a variety of system configurations to be flown with a minimum quantity of motor hoists Horizontal angle adjustment between cabinets has been limited to specific settings to ensure correct acoustic coupling Elevation control between cabinets is implemented in 2 increments to enable fine vertical adjustments Before proceeding with assembly of X BOW please check the contents of the carton against the enclosed packing list and ensure that the components are correct and undamaged In the event of any shortage please contact your supplier X BOW flying systems are professional precision tools and should be handled with extreme care Only persons who are fully conversant with the operation of X BOW and provided with suitable safety equipment should install and operate Misuse of X BOW could lead to dangerous consequences Please refer to the safety section of this manual for advice concerning X BOW installation and han dling NEXO offers flightcase packaging for X BOW to ensure that the various components can be transported safely Consult your dealer for further information Used and maintained correctly X BOW will give many years of reliable service in touring sys tems Please take the time to read
