An optical audio switch is the ideal solution when you want to connect multiple devices to a single amplifier or soundbar. Many audio setups run into limitations because they only have a limited number of optical inputs, while the number of source devices keeps growing. With an optical audio switch, you can easily switch between your TV, game console, Blu-ray player and streaming box, without swapping cables and without losing audio quality.
This solution is suitable for both home use and professional environments where clarity and reliability matter.
What is an optical audio switch
An optical audio switch, also called a Toslink switch, combines multiple optical audio inputs into one output. You connect different audio sources and actively choose which source is played through your amplifier, soundbar or DAC.
Unlike a splitter, the signal is not divided. The switch always sends through one selected source, fully digital and without noise or interference.
When do you use an optical audio switch
Too few optical inputs
Your soundbar or amplifier often has only one optical input. Want to connect multiple devices, such as a PC, CD player or game console? An optical audio switch lets you connect multiple audio sources to one input and switch easily between them.
Keep your older amplifier
Older amplifiers without HDMI remain popular because of their sound quality. An optical audio switch makes it possible to connect modern devices without replacing your amplifier.
Gaming setup with multiple consoles
If you use multiple game consoles, you want to switch between sources quickly. An optical audio switch avoids constantly unplugging and reconnecting cables and keeps your setup neat and organised.
Audiophile and professional applications
When using DACs or in studios and presentation rooms where multiple sources come together, an audio switch provides stable and tidy signal routing.
Optical switch versus optical splitter
The difference between a switch and a splitter often causes confusion.
Optical audio switch
- Multiple inputs to one output
- You actively choose which source is playing
- Ideal when you do not have enough inputs
Optical audio splitter
- One input to multiple outputs
- All outputs receive the same signal
In short: a switch selects, a splitter distributes.
Connect TS21
What to look for when choosing an audio switch
Number of inputs
Decide how many sources you want to connect:
- 2 inputs for simple setups
- 4 inputs for advanced home cinema or gaming setups
Control options
There are different ways to control the switch:
- Manual switching via a button on the device
- Control with an (infrared) remote control
- Automatic source selection based on the active signal
A remote control adds extra convenience when the switch is placed out of sight.
Support for audio formats
Check support for:
- LPCM for stereo audio
- Dolby Digital and DTS for surround sound
- Sample rates up to 192 kHz
- Noise-free audio quality
No delay
For video and gaming, lip sync remains important. A good optical audio switch switches without noticeable delay.
Connecting an optical audio switch
Installation is simple and takes just a few steps:
- Connect all audio sources to the inputs using optical cables
- Connect the output to your amplifier, soundbar or DAC
- Provide power to the switch if required
- Select the desired source
LED indicators show which input is active.
