3 x 1 optical audio switch with bi directional manual control What it does Connects 3 digital audio sources to a single digital output, or routes one input to 3 outputs, using a bi directional manual switch. Supports 3 input fiber optic Toslink digital audio connections and 1 output Toslink connection. Output connects directly to a TV or home theater receiver, enabling flexible source selection without unplugging cables. PCM, Digital and DTS signals pass through the unit without conversion. Key benefits Simplifies switching between multiple optical audio sources to a single display or receiver. Expands the optical input capacity of a home theater or AV receiver by providing additional input ports. Maintains native digital audio formats (PCM, Digital, DTS) for clean, reliable sound transmission. Bi directional design offers flexible assembly to match your existing cabling and device layout. Easy to install and operate with a straightforward, manual switching mechanism. Ports and compatibility Four optical digital jacks in total: three input Toslink ports and one output Toslink port. Output jack wired to the main unit (TV or AV receiver) to enlarge the number of optical connections. Three input jacks connect to devices (players, consoles, streamers) and route digital audio to your main unit. Use scenarios Scenario 1: You have three digital sources (Bluray player, game console, streaming box) but only one optical input on your TV or AV receiver. Use the switch to select which source is sent to the display or receiver. Scenario 2: You want to expand your AV receiver's optical input options. Connect each device to one of the three inputs and connect the switch's output to the receiver's optical input. Scenario 3: In a bi directional setup, configure the connections so that a chosen device can route its audio flow to the main unit or vice versa as your system requires, using the four Toslink ports. Size, material and performance Compact optical switch with four Toslink ports designed for straightforward integration into standard home theater layouts. Built to pass through native PCM, Digital and DTS signals without alteration, preserving audio integrity through the switch. Summary This device provides a practical, reliable solution to manage multiple digital audio sources with a single optical connection to a TV or AV receiver. It expands input capacity, preserves signal formats, and offers flexible, bi directional switching to fit a variety of home theater configurations.
