product presentationDo you have trouble at that how to connect 10 sets stereophonic signal source and 2 sets output equipment?Do you have trouble at that how to connect 2 sets stereophonic signal source and 10 sets output equipment?One strong stereophonic shift distribute device able to solve the problems that multiply equipment plug in and out, double way use.1. 10 sets stereophonic input adopt 10 gears mechanical switch manually shift, gears switch will not generate burst sound when shifting2. 2 sets output switch shift, 2 sets output cant be output at the same time.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 experience4. 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. 10 sets audio frequency signal 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.6. This product able to realize two operating methods, 10 input 2 output, reversely wiring realize 2 input 10 output, double ways use.Product ParameterMaterial: metalColor: blackInterface: RCA interfacePower supply: neednt additionally connect power supply, able to be used once insertedInput and output impedance: 10K - 50KFrequency responding: 20 - 20kHz.Distortion:
