1. What are the physical connectivity options for Phantom Premier and its accessories?

Phantom has an optical input. On Phantom, this entrance is located at the back of the Phantom, accessible once the electrical plug is disconnected.  

From the optical input, you can connect a variety of devices such as:

  • TV
  • Blu Ray
  • CD Player
  • DVD Player
  • A vinyl turntable
  • Your Internet router (if it provides you with TV access)
  • Laptop/Computer


Most devices that provide audio have this output.

The quality of the optical cable is essential, to avoid crackling when you play Phantom. In addition, the length of the cable is also important, the shorter the length, the less the quality delivered will be affected. 

We do not have specific brands to recommend, a simple search on the internet will help you find the right cable. 


This type of optical cable is also called Toslink.


If your external device does not have an optical output, it is always possible to use our Devialet Arch. You can find out any detailed information about this network hub here


There is also an Ethernet jack on the back of your Phantom, which will allow you to connect your Phantom directly to your router and network.








2. How can I activate the optical input in the Devialet App?

If you have one or more devices connected to your Phantom system via optical cable, you do not need to activate any particular option in the app. The optical input is always active and listening so as soon as an audio signal is received through this source, your Phantom system will play it.



3. Some additional information you need to know

If you want to use Phantom with your television, here are some important information to know:

  • The vast majority of TVs play Dolby or another proprietary format automatically as soon as a signal in this format is sent to it. At Devialet we don't consider this format as qualitative enough, that's why Phantom can't translate this format when it receives it and is therefore incompatible with Dolby, DTS, Surround or Dolby Atmos. We therefore recommend that you change the settings of your TV so that it does not use this format, and so that it allows your Phantom to play all the sounds presented to it. The recommended format in this case is the PCM format, which is the most standard and functional format on the market. To find this option on your TV, please refer to your TV manufacturer's information.

  • It is also recommended that you force your TV to play sound only on its optical output, rather than playing on the TV and Phantom speakers at the same time. Please consult the documentation supplied with your TV or simply consult the website of the manufacturer of your TV.

  • Finally, TVs transmit a very low volume stream via the optical output as a general rule. If after your installation, you hear a weak sound on your Phantom, please play with the volume of your Phantom from Devialet App.

  • If no sound comes out after finalizing your installation, we recommend testing with another optical cable. As this type of cable is very fragile and sensitive, it may be damaged. To test your installation, you can always unplug one side of your optical cable and check that there is a red light in the cable when the cable is carrying a signal. If you do not have a red light, it is highly possible that your cable is not properly connected to the source.

We recommend our customers to consider their TV as the central unit in their installation. This means having only the TV connected to one of the Phantoms, rather than each device such as DVD / Blu-ray etc... This way you will have only one source to control (the TV) and set up, as it will be able to transmit a compatible signal to your Phantoms. Whenever you want to watch a DVD, Blu-Ray, or even just watch TV, your Phantom will play these signals through its connection to the TV.



3. FAQ


  • When I play sound from my TV or DVD player with my Phantom, I have a delay between video and sound - how do I adjust this latency?

This is called: "Lipsync".

The connection between the TV and your Phantom system can generate a constant latency of around 160 ms (this value may be lower depending on the audio signal processing specific to your TV). There are several solutions to compensate for this delay, and a large majority of televisions allow for adjustment and better synchronization of sound and video (this is usually called A/V Sync or Lipsync).

  • From a TV, by navigating in the audio/video settings, you should find an option for this setting, which will then have to be adjusted to 160ms (several tests with different values will allow you to define the right synchronization).
  • From a computer, many video software apps allow this adjustment too (such as VLC Player).
  • From a DVD or Blu-Ray player, some models allow this adjustment (like the OPPO-103).
  • From the Devialet app, you can adjust this with the "latency" setting bar at the parameters of your Phantom.


  • I would like to connect two different devices to the same optical socket on my Phantom - is this possible?

There are solutions of this type on the market that will allow you to centralize several optical sources in a single box.

Note: We usually recommend the Lindy brand for this type of equipment, this is the brand we use in our professional installations.

You will find here some devices of this type.  



  • Sometimes when I play via optical on my Phantoms, I get a crackling sound. How can I avoid it?

Different aspects have to be taken into account here:

  • The length of the optical cable affects the quality of the transmitted sound, it is the case for all Hifi materials, the shorter the cable, the better it will be for the quality of the sound rendered.
  • The quality of the cable has obviously a lot to do with the quality of the sound. Ask your sound dealer for advice.
  • It is possible to identify a problem on your cable or connection by simply unplugging one side of the cable and check if a red light is transmitted in the cable when it receives information. If there is no red light, either your connection on the opposite side is not made correctly or the cable is defective.



  • How can I get rid of the cable between my TV and my Phantom?

There are of course additional solutions for connecting your TV to your Phantom system, such as Airplay or Bluetooth. Please refer to your TV's documentation to find out how these protocols work as embedded in your TV equipment.

We still recommend using the Optical interface for a stable setup to play your Phantom with your TV. 



  • I have a Sonos Connect, how can I integrate my Phantom to a Sonos system?

Sonos Connect has an optical output, so you can simply plug it into one of your Phantom devices. Please follow the instructions above to activate the optical source on your Phantom. You will need to use the Sonos application to control the tracks you play.

Note: If you want to multi-room with Sonos and Phantom speakers, you may have latency between the two types of devices, so you can check the Sonos Help Center to see if latency is adjustable in Sonos devices.



  • Why do my Phantom switch to the TV input when it's off?

Some TVs switch an audio signal to optical even when they are turned off. As the Phantom's optic is always on, it will not consider this signal as silence, and will, therefore, decide to turn off any other source (Airplay, Bluetooth, etc) to play the "silence" sent by the TV. It is therefore recommended for the time being to disconnect the optical cable from the TV when you are not using it. 

A solution would be adding an ON/OFF optical switch.
