Used to switch between loudspeakers and amplifiers in home audio systems, selecting one of two amplifiers to output a pair of loudspeakers; one amplifier selecting one of two pairs of loudspeakers to output. It is not a mixer and cannot output simultaneously (AB will not output simultaneously, only A or B channel will work). It does not require a power supply. A/B manual switch selects A or B channel. 2 power amplifiers >> 1 pair of loudspeakers: Use the A/B switch on the front of the switcher to select the A or B output of the two amplifiers and use a pair of loudspeakers. 1 power amplifier >> 2 pairs of loudspeakers: For the output of a power amplifier, use the A / B switch on the front of the switcher to select A or B of the two pairs of loudspeakers. The purpose of this is to avoid repeated plugging and unplugging of cables and wear and tear on the contact points of the socket. This is a great idea to solve the problem of plugging and unplugging speaker cables.
