5.1 SAFETY FIRST
Before proceeding with installation of 45°N-12, please ensure that the components are present and
undamaged. In the event of any shortage, please contact your supplier.
Statistically, many more injuries occur due to unstable ground set systems than those associated with
flown systems. There are several reasons for this fact, however the message is clear:
Always survey the supporting structure upon which 45°N-12 is to be set. Inspect stage support and if
necessary ask for the stage scrims and dressings be removed to allow access.
If the stage surface slopes, as it does in some theatres, ensure that the system is prevented from sliding
forwards due to vibration. This may require the fitting of timber battens to the stage floor.
For outdoor systems ensure that that the system is protected from wind forces which might cause the
monitor system to become unstable. Wind forces can be huge, especially upon large systems, and
should never be underestimated. Observe meteorological forecasts, calculate the “worst case” effect
upon the system prior to erection and ensure that the system is secured appropriately.
Be aware that safety procedures are as important in the truck and in the warehouse as they are at the
venue.
5.2 45°N-12 Coverage
Below figures illustrate 45°N-12 horizontal and vertical coverage behavior.
Main coverage features are:
- 30° horizontal coverage, scalable by 30° steps by arraying units;
- Asymetrical vertical coverage, defined so that frequency response level within +/-3 dB
from 0 to 2 meters.
