Additional information covers how to choose a speaker selector switch and why you should use one.
Connect the left and right channel outputs of the amplifier/receiver to the inputs of the switch.
Connect the speaker sets to the speaker outputs.
Match the speaker connection (banana plugs, spade connectors, pin connectors) to the speaker selector switch.
Consider installing a volume control module between each speaker set and the switch.
The easiest and safest solutionand also the most cost-effectiveis to use a speaker selector switch.
Some models also offer independent volume control over each pair of speakers.
This kind of switch handles more speakers, and it protects the amplifier or receiver from damage.
Low-impedance problems arise from playing multiple speakers at the same time.
Amplifiers and receivers are usually rated for speakers with 8 ohms of impedance.
Some are rated between 4 and 8 ohms, but 8 tends to be the norm.
Theimpedance specificationis important because it determines how much electrical current flows to the speakers.
Connecting additional sets of speakers increases the total amount of current.
Three pairs results in 2 ohms of impedance, and so on.
If the current flow increases much, it can exceed the ability of the receiver.
Choosing a Speaker Selector Switch
A wide selection of speaker selector switches is available.
Internal Selector Toggles
Your stereo receiver offers a built-inswitch to toggle A and B speaker sets.
This option supports a second pair of speakers, typically for a different room.
Typically, the receiver can safely handle both sets operating at the same time.
