1. Using the chart above select Amplifier Output Capability; Example - 100W @ 8 = Terminal #3
2. The Negative of the Amplifier goes to #1 Terminal.
3. Find the Speaker Impedance Load from the appropriate chart below. Once again find the
amplifier power range (100W), then find the speaker impedance within that chart;
Example: Using Ohms law (10)70V Step Xfrmrs tapped @ 10W = (10/500 ) = 0.02 = (1/0.02) = 50
Therefore (+) of Speaker Lead goes to #6 Terminal.
4. The Negative of the Speaker also goes to #1 Terminal.
