70V SYSTEM CONFIGURATION
When designing a 70V system, the total of all the power tap settings of all the connected speakers cannot exceed the output power of the 70V amplifier.The example below shows five speakers connected in parallel. Using the 16W termi- nals, an amplifier is needed with a power rating of at least (5) × (16) = 80W. A good rule of thumb is to select an amplifier with 20% more power; in this case, an amplifier that delivers about 100W.

This example uses the 16W tap. In a real installation, any of the five 70V taps (8W, 16W, 32W, 64W, or 128W) may be used.
