Two Amplifiers to Two Pairs of Speakers Selector Switch (2 to 2) Manual Switcher 2 in 2 Out Metal Enclosure (AS 0202)

Used for switching loudspeakers and amplifiers in home audio systems, selecting one of two amplifiers and outputting one of two pairs of loudspeakers. It is not a mixer and cannot output simultaneously (AB will not output simultaneously, only one channel of A or B will work). It does not require a power supply. A manual switch selects channel A or B.2 amplifiers >> 2 pairs of loudspeakers:Use the "AMP-Select A/B" and "SPK-Select A/B" switches on the front of the switcher to select one of the two AMPs and send it to the Group A or Group B speakers.How to use:The switch is operated by swinging it up and down, the left (AMP) selects the amplifier and the right (SPK) selects the loudspeaker.Its function is to prevent 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: AS0202Features: 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: 2.94 Pounds / 1350 gPack weight: 3.44 pounds / 1580 gUnit size: 8.66×9.21×2.36 inches (22×23×6 cm)Pack size: 11.2×10.3×3.6 inches (28.5×26.2×9.2 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, you can either use a switcher with tube protection, or switch off the amp and then switch it on again after switching.
