6 In 4 Out RCA Audio Switcher Signal Selector Distribute Device Switch Control Do you have trouble at that how to connect 6 sets signal source output and 4 sets equipment? Do you have trouble at that how to make 4 sets equipment output send sound at the same time after 6 sets equipment select shift output? One strong stereophonic shift distribute device able to solve the problems that multiply equipment plug in and out, 1. 6 sets input adopt 6 gears mechanical switch manually shift, gears switch will not generate burst sound when shifting 2. 4 sets output has independent switch, able to start at the same time, also able to be closed independently, start at the same time no consumption at the signal source tone quality and volume. 3. Simple installation: Input and output, able to be used once inserted, convenient to install, signal source non consumption shift, then can enjoy different hearing experience 4. Mainly used to select and shift various stereophonic signal input mutually use to output one set or multiply sets equipment, example there has multiply stereophonic signal source (TV audio frequency, MP3 player, CD player, video game, mobile phone, PAD, computer, gramophone) and other equipment need output to power amplifier or source loudspeaker box. 5. 6 sets audio source select shift device solve the complex circuit plug in and out operation, unify connect the equipment signal source which need input to the shift device then easily convenient to select.
