System 5: Connecting speakers with transformers

1.Locate the input taps on your transformer. These taps are on one side of

the transformer and are rated in watts: 10, 5, 2.3, 1.25 or 0.62. Usually,

each speaker in a system uses the same wattage tap.

Connect the selected tap to the amplifier 70V RMS terminal.

If you wish a particular speaker to have a higher volume level, connect the

wire from 70V RMS to a higher wattage tap on the transformer.

2.Connect the transformer’s COMMON tap to on the primary side to the

amplifier COMMON terminal.

3.Connect the speaker’s (+) terminal to the transformer’s secondary tap

that matches the speakers’ total impedance. Located on the opposite side

of the transformer, these secondary taps are outputs, and are rated in

Ohms: 4, 8, or 16.

4.Connect the speakers’ (-) terminals to the transformer’s COMMON tap on

the secondary side.

Note: Before connecting the speakers, please be sure the total wattage of

the primary tap you use does not exceed the amplifier’s maximum 100 WATT

power rating.

Also: Avoid, where possible, multiple connections to the 70V RMS and

COMMON terminals.
