4 In 2 Out 2 In 4 Out RCA Audio Signal Selector Switch Device with Remote Control Do you have trouble at that how to connect 4 sets stereophonic signal source and 2 sets output equipment? Do you have trouble at that how to connect 2 sets signal source equipment and 4 sets output equipment? One strong stereophonic shift distribute device able to solve the problems that multiply equipment plug in and out, double way use. With remote control shift function. 1. 4 sets stereophonic input, 2 sets stereophonic output adopt digit switch shift and remote control shift, will not generate burst sound when shifting 2. Input and output able to be used once inserted, non consumption shift at input and output signal. 3. 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. 4. 4 sets signal 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. 5. This product able to realize two operating methods, 4 input 2 output, reversely wiring realize 2 input 4 output, double ways use. 1. 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 Product Parameter 1.
