3 to 3 RCA Audio Signal Switcher, Power Amplifier Selector Switch 3 in 3 Out, for CD Players, Radios, Decoders, Power Amplifiers, and Active Speakers (RCA 0303GL)

It is a selector for multiple audio signal sources in a home audio system, suitable for L/R channel equipment. For example, sources such as CD players, DVD players, radios, decoders, and switching between power amplifiers and active loudspeakers, and between the pre- and post-amplifier. It is a selector (3 inputs, 3 outputs), not a mixer, and cannot input/output simultaneously (ABC does not input/output simultaneously, only one channel can be selected to operate).Connect the output cables of various home audio type devices to the RCA inputs (on the back) of our unit. 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)The purpose of this is to eliminate the need for repeated plugging and unplugging of cables, to avoid wear and tear on the contact points of the jack, and to facilitate the PK comparison of audio equipment. This is a great idea to solve the problem of frequent plugging and unplugging of audio cables.Model: RCA 0303GLNet weight: 1.49 pounds / 670 gPack weight: 1.85 pounds / 840 gUnit size: 6.61×5.63×2.48 inches (16.8×13×6.3 cm)Packaging size: 9.45×7.5×3.5 inches (23.5×19×9 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-end and back-end 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 switching nor relay switching is immune. The relay closing time is short and the impact pulse is sharper. Well-designed front and rear panels make switching noise inaudible. If you encounter this problem, you can set the power amplifier tone to '0' or switch the power amplifier off and on again after switching.
