25V, 70.7V, and 100V Transformer Output Wiring
For transformer coupled operation into high impedance loads, connect your loudspeaker leads to the
barrier strip connections labeled "Audio Transformer." Connect the speaker home runs as follows:
• 25V - Connect the positive speaker lead to the terminal labeled "100" and the negative speaker
lead to the terminal labeled "70" (Figure 8).
• 70.7V - Connect the positive speaker lead to the terminal labeled "70" and the negative speaker
lead to the terminal labeled "0" (Figure 9).
• 100V - Connect the positive speaker lead to the terminal labeled "100" and the negative speaker
lead to the terminal labeled "0" (Figure 10).
Note: Refer to page 6 of this manual to the paragraph entitled "Calculating Constant Voltage Loads" to
determine how many transformer coupled loudspeakers you can drive with the Atlas amplifier.
