3 Installation
3.1 Targets
The targets supplied will come with drop rods, but
not necessarily horizontal mounting bars. It is
normally required that the customer or system
integrator source and supply these bars and a
means to mount the bars to the ceiling. A dedicated
grid is the best method of securing the target bars.
It is essential that whatever method is employed,
the target array must be secure and vibration free.
The optimum pattern of high and low targets can be seen in Appendix G. This
is an optimum pattern only; it is designed so that the maximum number of
targets will be identified, with the minimum number of low targets obscuring
high targets. For ease of installation and calibration, this pattern should be
observed while installing the targets on the studio ceiling.
However, if there are any obstructions in the ceiling preventing the mounting of
a high target (eg, ducting, air-conditioning units) then a low target will suffice.
The major objective when installing targets is to ensure that a roughly equal
number of high and low targets can be seen by the Target Seeking Camera in
any position in the studio.
The optimum distance between each target is studio height dependent, and
will be advised by the Vinten Radamec Project Manager.
Whilst installing the targets, note the identification number located on the back
of the target on the target map. This will significantly expedite the calibration
process.
