Upgraded Digital Toslink Fiber Optical Splitter 1 in 2 Out Audio Adapter Cable
1. Introduction
The ANDTOBO Digital Toslink Fiber Optical Splitter is designed to expand your audio connectivity by allowing a single digital optical audio source to be simultaneously connected to two different receiving devices. This device is ideal for scenarios where you need to output audio from one source, such as a television or game console, to multiple audio systems like a soundbar and wireless headphones.
Important Note: This splitter operates unidirectionally, meaning it converts one input signal into two output signals. It does not support reverse use (connecting two input devices to one output device).

2. Setup Guide
2.1 Before You Begin
- Ensure your television or audio source has a suitable optical square interface.
- Remove the transparent protective covers from all optical cable ends before insertion. Failure to do so will prevent proper connection.
- A USB power adapter (not included) is required to power the splitter. The included USB-C cable connects the splitter to a USB power source.
2.2 Connecting the Splitter
- Connect the male optical port of the ANDTOBO splitter to the digital optical audio output port of your source device (e.g., TV, PS4, X-Box).
- Connect your first receiving device (e.g., soundbar, Hi-Fi system) to one of the two female optical output ports on the splitter using a Toslink optical cable.
- Connect your second receiving device (e.g., headphones with optical input, Bluetooth adapter) to the remaining female optical output port on the splitter using another Toslink optical cable.
- Connect the included USB-C power cable to the splitter's USB-C port and the other end to a USB power source (e.g., a USB wall adapter, a USB port on your PS4 or TV).

3. Operation
Once all connections are securely made and the splitter is powered, the digital audio signal from your source device will be simultaneously transmitted to both connected output devices. You can now enjoy audio through both devices at the same time.
Remember, the splitter is designed for a 1-input to 2-output configuration. Attempting to use it in reverse (2 inputs to 1 output) is not supported and will not function correctly.
4. Care and Maintenance
- Keep the device clean by wiping it with a soft, dry cloth. Avoid using liquid cleaners or aerosols.
- Store the splitter in a cool, dry place away from direct sunlight and extreme temperatures.
- Handle optical cables and ports with care. Avoid bending optical cables sharply, as this can damage the fiber.
- Always replace the protective caps on optical cable ends when not in use to prevent dust and debris from entering the fiber.
