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. INPUT TAPS OUTPUT TAPS 1W 16 OHMS 2.5W 10W 8 OHMS 4 OHMS COM COM FOUR OHM SPEAKER SHOWN 10

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.
