I purchased this new in March 2024, but I'm selling it because I no longer need it. This is an audio line selector that allows you to switch between audio devices equipped with stereo RCA terminals in a configuration of 2 inputs to 4 outputs or vice versa. **Product Features:** ■ Simple RCA Interface Usable in Both Directions The input/output terminals are designed to be used in both directions, supporting either 2 inputs to 4 outputs or 4 inputs to 2 outputs. ■ Convenient and Simple Remote Control Included The included remote control allows you to easily switch between multiple device connection configurations with the touch of a button, without having to move from your listening position. ■ Precise Control and Attention to Detail Designed Specifically for Audio The dedicated design, which considers crosstalk, employs carefully selected high-performance components from Japanese manufacturers, fulfilling its capabilities as an audio device despite its small size. Precise MCU control minimizes the open time of the contacts to suppress switching noise. Equipped with a selection state memory function, it starts up with the selection settings from the last power-off when the power is turned on, and is designed to be user-friendly, going into a safe open state (all terminals are disconnected) when the power is turned off. **Product Specifications:** Brand: FX-AUDIO- Series: ACCESSORY SERIES Product Model Number: LS-02J Color: Black Switching Configuration: 2 inputs – 4 outputs Input/Output Terminals: Stereo RCA terminals (gold-plated terminals) Functions: 2 inputs to 4 outputs switching, remote control support, selection state memory function Power Consumption: 1W (0.2W in standby) Power Supply: DC12V / Power capacity 0.5A or more Power Connector: DC jack, outer diameter 5.5mm x inner diameter 2.1mm (center positive) Accessories: Infrared remote control, USB power cable, instruction manual Size: Width 117mm x Depth 107mm x Height 35mm (excluding protrusions) Weight: 335g
