* Where to install the projector?
To indicate a correct installation position it is necessary to know the distance :
- projector - ceiling
- projector - screen
To find this correct position for the BARCOVISION 701 MULTIMEDIA, equipped
with HD145 lenses, formulas are given in the next paragraph.
Abbreviations used on drawing and diagrams on next pages
B = Distance between ceiling and top of the screen.
A = Correction Value, extra value to be added to B to obtain the correct
installation position. (In some cases the A value can be negative.)
CD = Total distance between projector and ceiling.
CD = A + B (When the result is negative, enlarge the distance between
ceiling and top of the screen, mount screen lower, until CD becomes zero
or positive)
SW = Screen width.
PD = Perpendicular distance between screen and projector.
Formulas for Projector to screen distance and correction value A with regard to the
screen width for HD145 lenses (metric).
Formulas (metric)
PD[m] = 1.21 x SW[m] + 0.213
A[cm] = 12.95 x SW[m] - 22.83
Formulas for Projector to screen distance and correction value A with regard to the
screen width for HD145 lenses (inch).
Formulas (inch)
PD = 1.21 x SW + 8.39
A = 0.1295 x SW - 8.99
