Speakers

One Speaker

Connect the speaker’s negative (–) ter-

minal to the amplifier’s

COM

(common)

terminal. Then connect the speaker’s

positive (+) terminal to the amplifier’s

terminal that matches the speaker’s im-

pedance. For example, if you have an 8-

ohm speaker, connect the speaker’s

positive terminal to the amplifier’s 8-ohm

terminal.

Two or More Speakers Without

Transformers

We recommend connections without

transformers if the length of the connect-

ing wires between the amplifier and the

speakers is 50 feet or less.

When making connections without

transformers, all the speakers must

have the same impedance rating to en-

sure equal volume from each speaker.

When there is more than one speaker in

a sound system, you must determine the

total impedance of the speakers before

you can make the correct connection.

The total impedance of all the speakers

must match one of the amplifier’s output

terminals (

Speakers in Series

1. To determine the total impedance of

speakers connected in series, add

the impedance of all the speakers.

For example, if you want to connect

two 8-ohm speakers in series, add 8

(the impedance of one speaker)

plus 8 (the impedance of the other

speaker) for a total speaker imped-

ance of 16 ohms.

2. Connect the first speaker’s positive

(+) terminal to the second speaker’s

negative (–) terminal.

3. Connect the first speaker’s nega-

tive (–) terminal to the amplifier’s

COM

terminal.

4. Connect the second speaker’s posi-

tive (+) terminal to the amplifier’s

terminal that matches the total

speaker impedance (
