1. Optical fiber audio converter TV, PS4 connected to the power amplifier speaker, the TV is connected to the speaker with double lotus interface through the coaxial interface2. TV fiber to speaker, TV fiber interface and 3.5mm interface speaker connection3. Headphones and speakers are used simultaneously, dual-channel audio output at the same time, synchronization without delay4. HiFi high-fidelity lossless sound quality transmission adopts HiF circuit design, electronic noise reduction, pure timbre, no noise without current, no distortion, avoiding the defects of multiple Spaces5. Independent power supply, sound synchronization without delay, with power supply line, no need to install drivers, stable sound quality without attenuation6. High-performance chip, clearer sound, fuller tone, high-speed CPU operation, effectively reduce electromagnetic interference, longer service life7. No need to install the driver, the sound can be output synchronously after connecting and pluggingName: Digital Fiber Coaxial Audio ConverterInput: digital fiber / coaxialOutput: RCA left and right channels / 35 stereoChip: Highly integrated conversion chipProduct weight: about 55gcolour:GoldMaterial:metalsize:Product size: 78 * 54 * 24mmPackage Contents:1*Audio ConverterOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
