FILES THE BILL IN MEETING ALL

PIIWER REIIUIREMENTS EIIR . .

Exhibitors everywhere are finding out that they are faced with new problems when 3-D equipment is installed. One of the chief obstacles is getting increased amperage and additional screen illumination to meet the basic needs of 3-D projection.

Loss of light through use of filters plus giant screen sizes makes existing projection equipment inadequate to do the job.

Manufacturers have increased carbon-arc amperage and voltage requirements up to 50% for 3-D projection, hence additional power is mandatory.

Fortunate are theatre operators, for Hertner has tried and proven motor generator

units that more than meet the maximum power requirements of 3-D projection. One of these is the "CP" TransVerter that has been widely accepted for use in large

theatres and drive-in theatres.
