2(1)-in-1(2)-Out Speaker Amplifier Switcher Stereo Home Audio Selector Passive Switch Box Banana Connector Silver-Plated Audio Cable Banana Jack Switch Box Amplifier Selector (AS 0201)

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.Model: AS0201Features: High current silver alloy contact switch, 2.5 square metres of silver plated single crystal copper wire, pure copper gold plated banana jacks, selected parts are hand welded using a soldering station.Net Weight: 1.6 Pounds / 725 gPack weight: 1.98 pounds / 900 gUnit size: 6.57×5.83×2.44 inches (16.8×14.8×6.2 cm)Pack size: 9.25×7.48×3.54 inches (23.5×19.2×9 cm)Notice:There is no protection or impedance matching circuitry inside the switcher, but with the exception of many tube amps, it is very unhealthy to switch on with no load (no speakers) connected; so if you have a tube amp, this is the option Use a switcher with a tube protection function, or switch off the amp and then switch it on again after switching.
