Wireless hand-held units and cue buttons on the lecterns provide direct
control of forward and reverse in PowerPoint.
A local stage receiver minimises the chance of a missed cue. Used in
conjunction with confidence monitors the presenter has the advantages of
direct control without the disadvantages of having the computer on the
lectern. The system can be switched to manual by the crew, to take control
from the presenter, reverting to a traditional cue light system. This is
particularly useful at speaker change-overs when the crew have to load the
next presentation.
This system can be expanded to have a number of wired and wireless buttons
over considerable distances.
This is a tried and trusted system that is popular with presenters since it's
simple, reliable and there is no delay.
