The connections from the amplifiers to the MSX Passive(s) and the first set of four WPMs are most conveniently made at
this stage.
Wheel the next set of four WPM cabinets on their flightcase base into position below the suspended array. Adjust the hoist
and the flightcase base so that the lowest cabinet in the array is in a convenient position to be mated with the top cabinet in
the next set of four cabinets. Attach the front of the two cabinets with Rigging Pins.

Raise the hoist further to bring the next set of WPMs off the flightcase base. As they rise up, set the correct inter-cabinet
angles (refer to the DISPLAY data) at the rear fixing with Rigging Pins as before.
Continue raising the array on the hoist until the lower edge of the bottom WPM cabinet is at the height defined by the
DISPLAY software. If the Flying Frame tilt angle is fitted with an inclinometer, the tilt can be checked with the inclinometer
display. If a single hoist attachment is being employed, the suspension employed will ensure that the array’s centre of
gravity will set the tilt at the correct angle. If using two hoists, adjust the rear relative to the front to set the back-to-front tilt to
the angle defined by the DISPLAY software.
