If you have multiple power amplifiers or speakers in your home, it is troublesome to unplug and plug in each time you change the power amplifier or speakers. Our PW-6 can solve this problem well. PW-6 is a 3-channel audio switcher that supports one-in, two-out or two-in and one-out bidirectional switching. It is convenient for you to connect one speaker and two pairs of power amplifiers at the same time, or two pairs of speakers and one power amplifier. And it can ensure the sound quality is clear, the signal is stable and not distorted.
