Andoer 1-in-4-out Stereo Audio Amp Signal Distributor 1 Channel Input 4 Channels Output RCA US Plug black

If you want to run several long lines between the TV audio line and a receiver on the other side of the room, provide high gain through any line level signal source, allow longer cable lines to run, or require buffering to solve low volume problem, you shouldn t miss this stereo audio distribution amplifier. You can use it to add signal amplifiers between the line level signal source and the power amplifier, and the RCA jack matches almost all other product interfaces.This product can increase the sound quality of the control signal and reduce the bottom noise. Features: 1 * input interface for connecting TV audio, MP3 player, video game machine, smartphone, tablet, computer, record player and other line level signal source devices. 4 * output interfaces for connecting power amplifiers, speakers or headphones to achieve 4-channel stereo audio output simultaneously, and improve sound quality and reduce noise. Input and output both adopts standard RCA interfaces, compatible with most audio devices, straight plug and use, easy to use. 4 stereo outputs use high-precision potentiometer, supports independent volume adjustment and has an independent signal gain amplification function(+20dB). Input power is controlled by switch, and comes with a power adapter for more convenient usage. Compact size design, lightweight and portable, and won t take up much space.
