By recording a tone
of
below
1 KHz on one of the tracks of
a
Multi-Track tape
recorder
it is
possible
to
trigger
a sequence of lighting scenes automatically in
perfect sync
with
a sound-track .
EXAMPLE -A piece of music
has been recorded in stereo on tracks 1 and 2 of a
4-track
recorder
.
At various stages in the composition lighting changes are
required .
1 .) The sequence of lights
is programmed
in
the CD sequencer
.
2 .) A suitable tone,
such as a bass beat or low speaking voice, should be
recorded on Track 4 wherever a lighting scene change is required Using the
adjacent track
3
is likely to result in cross-talk problems and is not advisable .
The
duration of this audio
signal is not important as it only requires a signal of
less than 50 milliseconds to activate a GO cue .
