Separate volume controls
Up to 150-foot reach
The avedio links Optical Audio Cable Splitter is a one-to-two TOSLINK distribution device rated 4.3 stars by shoppers. It is designed for users who want one source, such as a television or game console, to feed two receivers without continually swapping optical cables. Its most attractive feature is the stated support for separate volume controls on the connected soundbar and headset.
Pros
- Shares audio with two receivers
- Independent volume adjustment
- Broad source compatibility
- Long stated transmission distance
Cons
- Passive signal division
- Only one source at a time
We may earn a commission when you buy through this link, at no additional cost to you.
The splitter accepts a standard male optical input and provides two female outputs for equipment such as soundbars, digital amplifiers, digital-to-analog converters, and optical Bluetooth adapters. Supported formats include uncompressed PCM and 5.1-channel audio, including Dolby Digital Plus, DTS-HD High Resolution, and LPCM. The listing also states a maximum optical-cable distance of 150 feet with controlled loss.
Its practical limitation is that splitting is passive, so the available signal is divided between the two paths. The design supports only one active input at a time, and the separate volume-control claim ultimately depends on the connected receiving devices providing their own volume adjustment. Some receivers may also impose format or control limitations that are outside the splitter itself.
This is a strong recommendation for households that regularly divide listening between a soundbar and headphones or another speaker system. It combines a familiar 1-in-2-out layout with generous stated format support, plug-and-play operation, and a long-distance claim. Buyers should keep output cables within the stated transmission parameters and verify that both destinations accept the selected digital format.
Useful for Personalized Listening
Because each receiving device can retain its own volume setting, one listener can use headphones while another adjusts a soundbar or speaker system. This is particularly useful late at night, when the headphone user needs a lower level than the person watching television in the room.
Connection Flexibility for Modern Devices
The input and outputs are designed around common TOSLINK sources and receivers, covering consoles, disc players, set-top boxes, amplifiers, converters, and Bluetooth adapters. That broad device support makes it easier to build a shared digital-audio setup without introducing an unnecessary analog conversion.

- No 7.1-channel support
- Optical cables not included
We may earn a commission when you buy through this link, at no additional cost to you.
The listing specifies support for 5.1-channel Dolby-AC3, DTS, PCM, and LPCM 2.0 audio at 32 kHz, 44.1 kHz, 48 kHz, and 96 kHz. A shielded aluminum alloy body is intended to reduce interference, while over-voltage protection adds a measure of safeguard against an unmatched power adapter. The stated output reach is up to 25 meters, or 80 feet.
An important limitation is the explicit exclusion of 7.1-channel Dolby Digital Plus and Dolby TrueHD because those formats cannot be transmitted over the cited optical-fiber arrangement. Optical cables are not listed as included, and distributing one source across three paths divides the available signal more broadly than a two-output splitter.
Buyers who need three simultaneous destinations and use compatible 5.1-channel or stereo digital sources will find this configuration especially useful. It is less appropriate for modern surround formats that require 7.1-channel support. Confirm the source's output format and the receivers' optical input capabilities before installation.
A Three-Device Distribution Path
A three-output splitter reduces the need for multiple source devices in a room with several sound zones. Each receiver needs a compatible optical input and its own optical cable, allowing a television or player to serve multiple amplifier or speaker locations.
Shielding for Shared Equipment
The aluminum alloy enclosure and stated over-voltage protection are useful qualities for a component that may sit near several connected entertainment devices. The LED-free design remains simple, while the supported sample rates cover many conventional music and movie sources.

We may earn a commission when you buy through this link, at no additional cost to you.
A male optical plug serves as the input, and two female ports connect to receivers. The device uses a low-jitter synthetic fiber core with a precision-polished PMMA core, while the black braided jacket and metal connectors are intended to reduce vibration and wear. The listing states support for DTS, surround sound, and 5.1- or 7.1-channel configurations.
The routing requires attention. Although the splitter is designed to feed two receivers simultaneously from one source, using it in reverse to combine two sources into one receiver requires powering off one source before using the other. Its passive design also means signal strength is shared, and very long or poorly fitted optical leads may affect stability.
SOUNDFAM is a sensible option for a simple, powered-free installation with compatible digital equipment. It offers a clean two-way arrangement and a range of format claims for home cinema users. It is best suited to straightforward source sharing rather than advanced multi-zone distribution.
No-Power Simplicity
Because the splitter requires no external power, setup is limited to connecting the source and receivers. This reduces cable clutter and makes the unit convenient for a television, console, or compact home-theater system where every available outlet matters.
Flexible Two-Receiver Use

Its stated format support covers LPCM 2.0, DTS, and Dolby-AC3. Built-in one-meter optical fibers make the unit more self-contained than a splitter that requires every lead to be purchased separately. A power indicator shows operating status, and the listing claims a maximum output distance of 40 meters with optical cable loss below 0.2 dB per meter.
The package description refers to one optical cable being included, so buyers needing three output connections may still require additional suitable leads depending on how the built-in cables are arranged. The supported formats do not include 7.1-channel audio, and sharing a signal across three destinations can reduce headroom compared with a two-output device.
This splitter is a strong choice for a compact installation where one source must serve several digital receivers. Its integrated cables and status light simplify setup, while the range of stated compatible devices covers consoles, set-top boxes, HDTVs, and legacy media equipment. It is best for stereo and 5.1-channel sources rather than advanced 7.1-channel material.
Integrated Cables Simplify Installation
Built-in one-meter optical fibers reduce the number of loose connections surrounding the splitter. This makes the unit easier to place near a media console and can provide cleaner cable routing when each receiver is within a modest distance.
Three-Output Room Distribution
The three-output arrangement is useful for shared listening zones, powered speakers, or a soundbar and headphone system receiving the same source. Because the source is divided, careful testing is advisable to confirm stable audio on every connected path.

Buying Guide – How to Choose the Best Optical Audio Splitter
The right optical audio splitter depends on how many sources and receivers you need, the digital formats your equipment supports, the distance between connected components, and whether you prefer a passive, powered, or bidirectional design.
Choose the Correct Routing Configuration
A one-to-two splitter is the most common configuration and takes one optical source to two playback devices. A one-to-three splitter is useful when television or console audio must reach three sound zones, receivers, or headphone systems. Bidirectional splitters can also reverse their roles to connect two sources to one receiver, but only one source may be active at a time. Confirm the physical gender and placement of the male input and female outputs because a splitter cannot combine two simultaneous streams into one output.
Choose the number of outputs that matches the actual installation. A three-output unit is unnecessary if only two receivers are planned, while a two-output splitter cannot provide a third connection. The routing direction and source limitations should be understood before buying.
Match Supported Digital Audio Formats
Optical splitters must support the format emitted by the source and accepted by both receivers. Common options include PCM, LPCM 2.0, Dolby-AC3, DTS, Dolby Digital Plus, and DTS-HD High Resolution. The lists vary significantly among the products reviewed, with some explicitly excluding 7.1-channel Dolby Digital Plus and Dolby TrueHD. A receiver may support a format when connected directly yet behave differently when the source is routed through a splitter.
Check the audio-format menu in the source device, the specifications of every receiver, and the splitter's stated list. If using surround formats, enable the correct digital output mode and test both outputs after installation.
Assess Cable Length and Signal Loss
Long optical runs can work reliably, but cable quality, connector seating, and the number of split outputs all matter. The products state different limits, including 80 feet, 150 feet, and metric equivalents. One model specifically recommends output leads shorter than 10 feet, while others advertise 25- or 40-meter transmission distances. These claims should be treated as product specifications rather than guaranteed performance in every installation.
Measure the route before purchasing and choose a model whose stated range comfortably covers it. Avoid unnecessary sharp bends, keep plugs fully seated, and test every output with the intended source format.
Decide Between Passive and Powered Designs
Passive splitters require no power and are simple to install, but the optical signal is divided between outputs. Powered models may provide more consistent distribution and useful status indicators, yet they require a reliable USB or other power connection. Several compact splitters in this guide are passive, while the three-output LiNKFOR package uses a 5V 1A USB cable.
Choose a passive unit for a nearby, uncomplicated installation with compatible receivers. Consider a powered model when distributing to several locations, using long runs, or wanting a visible operating status.
Consider Included Cables and Installation Ease
Cable requirements vary considerably. Some models include built-in optical leads, the three-output LiNKFOR premium package includes four six-foot cables, and other splitters require all output leads to be supplied separately. Built-in leads reduce clutter and make it easier to connect several nearby devices, while detachable cables provide greater routing flexibility.
List the devices that need connections, count the required leads, and check connector types before ordering. A complete package can be more convenient, but it may still be less economical if it includes longer cables than the installation needs.
Evaluate Build Quality and Interference Resistance
Optical fiber inherently reduces sensitivity to electrical interference, but housing quality, connector plating, strain relief, and shielding still influence durability. Aluminum alloy bodies are available on the LiNKFOR three-output models, while several smaller splitters use ABS or PVC construction. Braided jackets, gold-plated connectors, precision-polished fiber cores, and buffer sleeves are useful indicators of attention to signal and mechanical reliability.
For equipment that is frequently plugged and unplugged, pay particular attention to connector fit and strain relief. In permanent installations, a rigid enclosure can also reduce accidental movement around tightly packed entertainment furniture.
Plan for Independent Volume Control
Several listings emphasize separate volume control for two connected outputs. In practice, the splitter determines whether signals can be treated independently, while the receiving soundbar, amplifier, DAC, or headphone adapter usually controls its own level. This arrangement is valuable for shared listening because one user can lower headphone volume without reducing the television speakers for everyone else.
Verify that both receiving devices have their own volume controls and that their formats match. If the destination devices cannot adjust levels independently, the splitter cannot create that function by itself.
Review Warranty and Support
Manufacturer support can be valuable when a device does not recognize a source format or when a connector behaves inconsistently. The reviewed products offer varying support arrangements, including an 18-month unconditional warranty for one VANAUX model, a 36-month manufacturer warranty for KabelDirekt, and customer-service commitments from several other brands.
Compare the coverage period and the process for obtaining assistance, but do not rely on warranty terms as a substitute for checking compatibility. A product is more likely to work well when its source and receiver formats align from the start.
How to Use and Care for Your Optical Audio Splitter
Begin by identifying the source device's optical audio output and the desired receivers. Connect the source to the splitter's male input, or connect the splitter's outputs to the two intended playback devices. If the unit is powered, connect its USB power cable before switching on the source and receivers. Keep each optical plug firmly seated but avoid twisting the connector.
Select the matching digital audio format on the source. For example, a console may offer PCM, Dolby Digital, or DTS options, while some televisions distinguish between passthrough and automatic decoding. Enable the selected format and test each output independently before watching a full program. If one output is silent, reseat its cable, check the receiver's input selection, and confirm that the receiver supports the source format.
For care, route cables without tight bends or repeated pulling at the splitter body. Keep the device away from moisture, excessive heat, and heavy objects. Clean optical ports gently with a dry, lint-free method, and avoid inserting dust or metal objects into a receptacle. If the splitter behaves inconsistently, disconnect power where applicable, unplug the connections, and reconnect them one at a time.
Frequently Asked Questions
Can an optical audio splitter send sound to two devices at the same time?
Yes, a one-to-two optical splitter can send one source to two compatible receivers simultaneously. The signal is divided between both paths, so each output may have less headroom than a direct connection. Both receivers must also support the digital format being transmitted by the source.
Can one optical splitter connect two consoles to one television?
Some bidirectional splitters can operate in reverse to connect two sources to one receiver. Only one source may be active at a time, so you must switch power or input selection manually. A standard one-to-two model may support this arrangement, but it is not suitable for playing both sources simultaneously.
Do optical audio splitters support surround sound?
Many do, but support varies by model. The products in this guide list combinations of PCM, LPCM 2.0, Dolby-AC3, Dolby Digital Plus, DTS, and DTS-HD High Resolution. Some explicitly exclude 7.1-channel Dolby Digital Plus and Dolby TrueHD, so check both the splitter and receiving equipment before purchasing.
Does splitting optical audio weaken the sound quality?
A passive splitter divides the available signal, which can reduce headroom or cause instability on one path, particularly with long cables or a marginal source. The device itself does not intentionally convert the audio into a lower-quality format. In practice, reliable connections, compatible formats, and suitable cable lengths help maintain stable playback.
Do I need additional optical cables for a splitter?
That depends on the package. Some splitters include built-in leads, while others include several loose cables, and some include none beyond the attached input section. Count the connections required for your source and receivers and check the package contents before buying additional TOSLINK or SPDIF optical cables.
Can I use a splitter for headphones and a soundbar together?
Yes, provided the soundbar and headphone receiver each have a compatible optical input. Many models emphasize independent volume adjustment for this arrangement, allowing each listener to set a different level. The receiver must handle the source's format, and the splitter must be configured for one source feeding both outputs.
Why does one output have no sound after connecting a splitter?
First, reseat the optical cable at both the splitter and receiver, then confirm the receiver has selected the correct optical input. Check that both devices support the source format and that the source is not sending an unsupported signal. If the splitter is passive, also test with shorter output cables because a divided signal can be less stable over long runs.
What is the difference between an optical splitter and an HDMI audio extractor?
An optical splitter distributes an existing digital optical audio signal to multiple receivers. An HDMI audio extractor normally takes audio from an HDMI connection and converts it to another format, often analog or optical. If the source already has a suitable optical output, a splitter is usually the more direct solution.
Final Thoughts on Choosing the Best Optical Audio Splitter
The avedio links splitter stands out as the most versatile one-to-two choice, with separate volume-control support, broad receiver compatibility, and a long stated reach. KabelDirekt is an economical bidirectional option for sharing one source or manually selecting between two, while the three-output LiNKFOR package is the most complete multi-device installation.
Prioritize the routing direction, number of receivers, digital formats, and cable distance before considering smaller conveniences. One-to-three models suit larger installations, compact one-to-two adapters work well near a single entertainment center, and bidirectional designs help when selecting between two source devices. Independent output levels are particularly valuable for shared soundbar and headphone setups.
Ratings and configurations can offer a useful starting point, but the exact device details remain decisive. Confirm the source format, receiver capabilities, power requirement, and included cables before ordering. Prices and availability change frequently, so checking current listings can help shoppers find the right optical audio splitter for their particular setup.
