| The film’s soundtrack is of utmost
importance in the IMAX Experience®.
It is broadcast throughout the theatre using a high-performance,
six-channel sound system, especially designed for IMAX®TELUS theatres.
Recently, the world’s first and only
radically redesigned IMAX® sound system
called ‘Kanga’ was installed
at the IMAX®TELUS theatre. The previous system’s
capacity was 15,000 watts; the new system now boasts
a 36,000-watt capacity, more than twice
the output! The major improvement brought on by this
new system is unequalled sound quality:
every element of the soundtrack is crystal-clear.
- The next generation ‘Kanga’ loudspeaker
has four times the output capacity over the previous
generation loudspeaker.
- In an IMAX® film, the soundtrack is separate
from the film reel, also known as a ‘double
system’ sound track. To ensure that the sound
is synchronized to the film as it was originally recorded,
its synchronization is ensured by an original SampleLock®
technology digital signal processor designed by Sonics®,
an IMAX® subsidiary.

The new sound system is comprised of six
Crest Audio high-fidelity amplifiers with six
new Kanga loudspeakers (exclusively developed for IMAX®).
The new Kanga speaker is twice as big and powerful (27,000
watts) as its predecessor. Four speakers are strategically
located behind the perforated screen and two are located
at the back of the theatre (on the right and on the
left). Each one weighs about 410 kilos.
To complete this new system, eight low frequency
9,000 watts speakers (subwoofers) are placed
at the base of the screen and are powered by four
Crest Audio high-fidelity amplifiers.
IMAX® sound system characteristics:
- Six-channel, high-fidelity
- Sub-bass
- Digital soundtrack
The effect? Spectators are totally
surrounded by the soundtrack. They can hear
fine details with remarkable clarity
and can physically ‘feel’ the full impact
of more intense moments. The sound experience rivals
the image: exceptional quality, far
beyond anything that conventional theatres can offer.
