3x1 Optical Toslink Digital Audio Switch, bi directional, manual operation. Expands the capacity of a home theater A/V setup with four optical jacks in total: three input jacks and one output jack. What it is and how it works Three input jacks and one output jack: A 3x1 optical Toslink switch that provides three input sources to a single digital audio output, enabling you to expand the optical inputs available to your main unit (typically a digital A/V receiver or amplifier). Bi directional manual switch: The unit is designed to be bidirectional and operated manually. It can route a chosen optical signal from the inputs to the output, or in some configurations route an input signal to multiple outputs. Output connection: The output jack connects directly to the main unit (receiver or amplifier) to expand the number of optical inputs available. Input connections: The three input jacks connect to devices such as optical audio sources and allow you to output digital audio to your main unit. Signal support: PCM, Digital and DTS signals can pass through this unit. Key benefits Easy expansion of optical audio inputs: Add three devices to a single optical input on your main receiver or TV, reducing the need to swap cables. Flexible routing: The bidirectional manual switch provides versatile routing options to fit different home theater layouts. Maintain digital audio formats: Passes through common digital audio formats (PCM, Digital, DTS) without altering the signal. Simple, reliable operation: A straightforward manual control keeps setup and use intuitive. Attributes and compatibility Four optical jacks in total: three inputs and one output. Three input devices can be connected to the switch to feed the main unit through a single optical output. Output is designed to connect directly to a TV or home theater receiver. Use scenarios Scenario 1: Multisource to a single AVR Connect three optical devices (for example, a Bluray player, a game console, and a streaming box) to the three input jacks. Connect the output jack to your digital audio/video receiver or amplifier. Use the switch to select which source is sent to the AVR, enabling you to enjoy any source through your home theater system without swapping cables. Scenario 2: TV audio routed through the home theater system Connect the TV's optical audio output to one input. Connect the switch's output to the home theater receiver. When you want TV audio through the AVR's processing, select the TV input on the switch. Scenario 3: Single source to multiple destinations (bi directional capability) In appropriate configurations, use the bidirectional functionality to route one optical source input toward three outputs as needed, allowing flexible distribution to multiple devices. Notes Output connects directly into the TV or home theater receiver. Designed to handle common optical digital audio formats, including PCM, Digital, and DTS signals. This description preserves the original product's function, the 3x1 Toslink configuration, the four optical jacks, and the bidirectional, manual switching capability, while presenting clear benefits, practical uses, and straightforward setup.
