Notes
  The Throw ratio for a particular 
lens is fi xed, and assumes that 
the image fi lls the width of the 
DMD.
  For images that do not fi ll the 
width of the DMD, the Throw 
ratio is effectively increased. To 
correct for this, a Throw Ratio 
Factor (TRF) is used.
  The lenses available and their 
part numbers are listed below:
High Brightness
0.63 : 1 fi xed lens 001-734
0.96 : 1 fi xed lens 001-735

will allow it to be suspended from a lighting truss or rigging. The four adjustable feet 
under the chassis allow the projector to be lowered onto a fl at surface without any 
danger of hands being trapped between the bottom frame and the surface.

Notes
 When stacking projectors, 
the stack MUST be vertical, 
to ensure that the stresses 
are distributed to all frame 
couplings.
 Make sure that the surface, 
ceiling or rigging that is 
to support the projector is 
capable of supporting the 
combined weight of all the 
projectors and lenses (see 
specifi cation for weights).
 Do not place heavy objects 
on top of the projector 
chassis. Only the chassis...
