KEF X300A Wireless - Hi-Fi Your Computer

HI-FI YOUR COMPUTER. NOW IN WIRELESS

At last - the freedom to stream music wirelessly via Airplay® or DLNA from your computer, smartphone or any other mobile device in a way that allows you to experience uncompromised high fidelity sound. Everything about the X300A Wireless digital hi-fi speaker system is designed to make your enjoyment of music easier as well as more intense.

KEF X300A Wireless


WIRELESS HIGH FIDELITY

Like a professional studio monitor, each X300A wireless speaker has two dedicated class AB amplifiers – one for LF/MF and one for HF – to ensure accurate, distortion-free sound reproduction. Speaker hum and electromagnetic interference are minimised by using toroidal transformers of the type specified for audiophile grade hi-fi amps. With digital USB connection between speakers, the X300A wireless system turns your desktop, laptop, tablet or other mobile device into a source of listening pleasure to true high fidelity standards.

WIRELESS HIGH FIDELITY

HIGH DEFINITION SOUND

A dedicated high quality DAC in each speaker virtually eliminates interference by separating decoding from playback, allowing the X300A system to reproduce the full depth and complexity of high resolution music files to the same standard as the artist intended. All this high end technology is complemented by the award-winning Uni-Q point source' driver array derived from KEF's flagship speaker, the Blade. The result is a spacious, accurate and exquisitely detailed sound field, whatever device your music is played from.

Please make sure your computer is close to the speakers to ensure they are not out of range from network. If problem persists, there are several actions to tackle this problem:

  • Make sure your anti-virus software and firewall are not blocking the Setup Wizard. Try to add the Setup Wizard to exceptions list of your anti-virus and firewall.
  • Make sure LAN cable is not connecting to the speaker.
  • If you have more than one pair of X300A Wireless running in wireless setup mode, Setup Wizard can only randomly connect to one pair in each setup. Try to do the setup one at a time.
  • Check your Wi-Fi network of computer. If you are connected to "KEF X300A Wireless" already, try to disconnect and go through "First time setup" again.
  • If problem persists, please try the wired connection method (details at B8).


B5: I cannot see the network selection page.

There are two common reasons to this problem, please try below solutions:

  • Turn off any proxy server. Click the "Refresh" button and try again.
  • Make sure your computer and speakers are within range of home router signal. Try to move your computer and speakers closer to the router.
    If you are running the Setup Wizard on PC, there may be random error from Internet Explorer. If the above actions cannot solve your problems, try to select home Wi-Fi network in the Wi-Fi network list of your computer. Restart the Setup Wizard and go through the "First time setup" again.
  • If problem persists, please try the wired connection method (details at B8).


B6: I cannot see my home Wi-Fi network in the network selection list.

There are several reasons for this problem:

  • Make sure your home router is using WPA2 security encryption.
  • Make sure your home router supports IEEE 802.11 b/g.
  • Check if your Wi-Fi network is automatically set at Channel 12-13. Try to manually set your Wi-Fi network to channel 1-11. For details please refer to the user's guide of your router.

B7: I have selected my home network and entered the password, why is my setup still unsuccessful?

First of all, check the light indicator of your speaker. If Amber light is on, you may have entered a wrong password and therefore X300A Wireless cannot connect to your home network.

  • Press and hold the standby button to turn off the speaker.
  • Press and hold again until Blue/ Amber light is flashing.
  • Go through the "First time setup" process again with the correct router password.

In the case where your PC fails to reconnect to your selected network, Setup Wizard will not be able to find the speakers. Check the Wi-Fi network your PC is connected to, ensure it is connected to your selected home network and refresh the page. You should then see a message indicating a successful setup. If problem persists, please try the wired connection method (details at B8).

B8: Can I do the setup without Setup Wizard?

Yes you can use the LAN cable came with the speaker to do the setup. If your computer is running an old OS, or do not have wireless connection or cannot run the Setup Wizard, this wired connection method should resolve your setup issues. This method can also avoid most of the wireless connection problems which leads to setup failure.

D2: I cannot see X300A Wireless from my streaming device.

Please make sure your streaming device and X300A Wireless are connected to the same network. If Amber light is on, please refer to the section "Error Signal" for troubleshooting.
Sometimes unstable network can cause this problem as well, if the above actions cannot solve the problem, try to refresh speaker list.

D3: I have selected X300A Wireless as output speaker, however streaming did not start.

First of all, check if blue light is blinking. If yes please refer to more information at section "H2: What should I do if I see the error signals?".
Sometimes connection between speakers and your device can be lost due to unstable network signal or random settings from your device. To resume connection, re-select X300A Wireless in the speaker selection menu / AirPlay menu, or close and restart music player. However connection drop-out should not be a regular issue, if problem persists please contact your local dealer or service help desk.
If there are no error signals and you can discover your speaker in the network, please be a little more patient. Streaming usually will not start immediately and AirPlay will take more buffering time. If you are playing lossless music formats, it will take a little more time to stream to speakers as well.

D4: Why my wireless streaming was sometimes interrupted?

Minor interruption during streaming is normal when there is weak Wi-Fi signal or heavy network traffic. Heavy streaming workload of your other Wi-Fi devices at home is one of the common reasons for this issue. To maintain quality streaming, we recommend you to avoid downloading and uploading activities during music streaming.
Signal interference by other nearby Wi-Fi devices can also weaken music streaming stability. If it is happening frequently, try to use a W-Fi analyzer app to detect the signal strength and look for a better signal channel. For details please refer to the user manual of your router.
