The speaker switcher allows the user to connect multiple pairs of speakers to a single stereo receiver or amplifier or vice versa to multiple amplifiers or receivers of a single speaker pair. The device has a convenient button terminal that can accept up to 12 AWG speaker lines. [Note]: this speaker switch does not allow multiple speaker pairs to be selected simultaneously. Only one pair of outputs can be selected at a time. This speaker selection can also be used in the opposite way, imagine having multiple amplifiers connected to a speaker pair for setting. Because each stereo amplifier has its own sound characteristics, the user can connect different power amplifiers to the switch and then output to the same speaker pair. Connect multiple speakers to an audio amplifier or receiver as loudspeakers to select a pair of speakers at a time. Connect multiple amplifiers or receivers to a pair of speakers as an amplifier selection to select one amplifier or receiver. The high-current amplifier protection circuit allows up to 6 pairs of speakers to be connected without damaging the amplifier.
