NOTE : When calculating total power requirements, determine the total number of
speakers needed in your installation, and divide the total by four. The result is the number
of amplifiers required for your installation. If the result is not a whole number, then round
up to the next whole number.
For example, if your site needs 1200 watts, then this is 12 speakers because each speaker
provides 100 watts of signaling power.
Consider the following example:
(12 speakers)/4 = 3 amplifiers.
This example shows that the power requirements are three 400 watt amplifiers.
