4 to 1 (1 to 4) RCA Audio Signal Switcher, L/R channel Power Amplifier Selector, 1 In and 4 Out Audio Switch, Suitable for CD Players, Radios, Decoders, Power Amplifiers and Active Speakers (RCA 0401)

It is a selector for multiple audio sources in a home audio system, suitable for L/R channel devices. For example, CD players, DVD players, radios, decoders and other sound sources, as well as switching between power amplifiers and active loudspeakers, and between pre- and post-amplifiers. It is a selector (4 in and 1 out, 1 in and 4 out), not a mixer, and cannot input/output simultaneously (ABCD cannot input/output simultaneously and can only select one channel for operation).Connect the output cables from various home audio-type devices to the RCA inputs on our unit (located on the rear panel). Easily switch between different audio sources by turning a knob on the front panel.Audio format: unbalanced analogue signalConnection cable: Coaxial audio cable (RCA signal cable)This saves the hassle of repeatedly plugging and unplugging cables, prevents wear and tear on the jack contact points, and makes it easier to compare audio equipment. This is a good idea if you have problems with frequent plugging and unplugging of audio cables.Model: RCA 0401 HGNet weight: 1.82 lbs/825 gPackage weight: 2.25 lbs/1020 gUnit size: 6.77×7.6×2.55 inches (17.2×19.3×6 cm)Package size: 9.8×8.3×3.5 inches (24.2×21×9 cm)Packing List:Audio Switcher×1Notice:The speaker may make a "pop" sound when switching. This problem is not related to the switch. It is related to the DC potential difference between the front and back of the switch. Whether it is pure DC coupling or capacitive isolation, as long as there is a potential difference, there will be a "pop" sound, and the size of the sound is proportional to the potential difference. Neither mechanical switches nor relay switches are immune. The relay closing time is short and the impulse is sharper. Carefully designed front and rear panels make switching noises inaudible. If you encounter this problem, you can set the amplifier tone to "0" or turn the amplifier off and on again.
