Designing a System
Use the following steps when designing an IR system:
1. Determine the number of audio channels that will be used (1 or 2).
2. Determine the room size and shape.
3. Use the room size and shape information along with the appropriate 1 or 2 channel coverage
pattern footprint to overlay the footprint on the room dimensions and determine the number of
units required and the placement of those units to cover the desired listening audience.
Best performance is achieved:
• When radiators face and have direct line-of-sight to audience.
• When a system provides over-lapping coverage (like a sprinkling system).
• When special coverage is provided for shaded areas like under a balcony.
• When mounted above and angled down into the listening audience
9 – 16 ft. (2.8 - 4.9 m) high and at an angle between 10 and 30 degrees.
