9.4 Recommended installation tools and equipment
Tape measure should be 30m/100ft in length and be of durable fibre material. Have one
per array available to speed up the installation process.
Spirit level used to ascertain the trueness of the surface from which the angle
measurements originate.
Rangefinder measuring device either a Disto type laser measure or an optical laser
rangefinder can be used. Devices such as the Bushnell ‘Yardage Pro’ sports rangefinders
provide sufficiently accuracy and are easy to use. They have the additional advantage of
working very well in bright sunlight.
Electronic calculator with trigonometric functions to calculate the height from ground level
to points in the room. The formula to calculate height of a point from measured angle and
distance is:
Height of point = Sin(vertical angle in degrees) x distance to point
NB: Take care when using spreadsheets as they calculate using radians by default. To
convert degrees to radians use the formula:
Angle (in radians)=3.142 x Angle (in degrees)/180
Computer Laptop or Desktop PC running Windows XP with the current version of NEXO
NS-1 installed. It is not possible to configure a Geo tangent array properly without using
NS-1. Note that, when NS-1 designs are prepared prior to arrival at the venue, it is often
necessary to modify or update the design to accommodate special circumstances. A PC
is absolutely essential to make such changes.
Audio Analysis Software recommended but not absolutely essential, programs such as
Easera Systune, Smaart, WinMLS enable rapid and detailed analysis of the installation.
Consider taking a training course in using one of these tools if you are not already
competent with them it will pay dividends in increased performance of the system.
