LS50 Wireless II
|B. PLAYBACK AND STREAMING|
A1. How do I set up LS50 Wireless II?
First of all, a home Wi-Fi network is required. This is to ensure you can enjoy the full range of features and keep the system up to date.
Then, download the KEF Connect App from the App Store or Google Play Store and install it on your mobile device. Follow the instructions in the KEF Connect App to get the speakers connected (onboarded) to your home Wi-Fi network.
A2. What router specifications does LS50 Wireless II support?
IEEE 802.11a/b/g/n/ac, IPv4, IPv6, Dual-band 2.4 GHz / 5 GHz
A3. Can I use a mesh router?
Yes, we have tested the most popular mesh routers and they are working well with LS50 Wireless II. However, as there is not yet an industrial standard for mesh routers, each manufacturer may have their own meshing technology. If your mesh router does not work with LS50 Wireless II, make sure you have updated your router to the latest firmware or contact the manufacturer for solutions.
A4. How far apart can I place the two speakers?
Wireless: up to 8 meters apart depending on your network condition. A congested network environment will have more interferences and may reduce this distance.
A5. How large a room can LS50 Wireless II cover?
A6. Can I change the Primary Speaker as the left channel?
By default, the Primary Speaker is the right channel and the Secondary speaker is the left channel. After connecting the speakers to your home Wi-Fi network, you can inverse the L/R channels in the KEF Connect App.
A7. Do I need to pair the two speakers?
No, the two speakers are already paired at the factory. If you do not hear any sound from the Secondary Speaker, see chapter “Troubleshooting”.
A8. What is the purpose of the ethernet cable in the packaging box?
Use this inter-speaker cable to connect the Primary Speaker and Secondary Speaker if you prefer a higher sound resolution (192 kHz/24 bit), or if the wireless connection between the speakers is not stable. After connecting the inter-speaker cable, you must also enable Cable Mode in the KEF Connect App.
A9. Can I rename the speaker?
Yes, renaming can be done in the KEF Connect App. This will change the name for both Wi-Fi and Bluetooth connections.

In the KEF Connect App:
C1. What should I do to set up LS50 Wireless II to another network?
A factory reset is necessary. This will clear the previous network settings and all EQ and system preferences. For this purpose, press and hold the Reset button (R) on the back panel until the LED light above the button blinks.
C2. What should I do if I cannot find my LS50 Wireless II in the network during set-up?
Wait for about 30–40 seconds for the speakers to be visible on the speaker list.
C3. How do I report a bug or an issue?
In the KEF Connect App, go to “Settings” > “Support”. To let us better understand the bug or issue, please provide a descriptive report.
C4. There is no sound from both speakers.
Check if the speakers are already turned on and not muted.
C5. There is dropout from both speakers.
Check if there is a network problem or you need to set up the speakers to a less crowded router channel.
Change the audio streaming quality in the KEF Connect App.
C6. There is no sound from the Secondary Speaker.
Make sure the Secondary Speaker is connected to power.
C7. There is dropout from the Secondary Speaker.
If the speakers are connected wirelessly, try to move them closer to each other.
C8. The audio is out of sync with the picture when using LS50 Wireless II with a TV.
If available, try the video delay/lip sync function of your TV.
C9. I have connected the speakers to the TV with an HDMI cable, why is there no sound?
Make sure the source is switched to TV for the speakers. Check the TV icon on the top panel of the Primary Speaker.
If the TV icon is blinking, the HDMI connection is not found. In this case, make sure that the HDMI cable is connected to the eARC or ARC port of the TV.
If the TV icon is pulsing (fade in/fade out), only CEC (not ARC) connection is established (TV may respond without sound). In this case, do the following:
The HDMI CEC connection needs to be enabled on the TV. As manufacturers may name this connection differently (e.g. Anynet+ for Samsung, Simplink for LG), please check the user manual of your TV on how to turn on HDMI connection for your TV. Once the HDMI CEC connection is enabled, the TV icon on the top panel should turn solid (both CEC and ARC connections are now established).
If there is only no sound but everything else is working, please make sure that the audio output of HDMI is set to PCM (this is often set to Dolby Digital by default). As the settings menu of each TV manufacturer is different, please refer to the user manual of your TV.
For HDMI eARC input, make sure the connecting HDMI cable is of high speed with Ethernet to provide sufficient bandwidth and speed.
Change the HDMI cable (our internal tests found that HDMI cables of lower quality may not be able to establish the connection).
If the problem persists, please report the issue in the Support section of the KEF Connect App for investigation. In the meantime, use the Optical connection as a fall-back solution.
C10.I have connected the speakers to the TV with an optical cable, why is there no sound?
Make sure your TV is set to output digital audio in PCM format.
C11.I cannot find a radio station or podcast in the KEF Connect App.
We are constantly updating and expanding our database for radio stations and podcasts. Please use the Support function in the KEF Connect App and send us the RSS link of the website. After verification, we will add it to our database.
C12.I cannot adjust the speaker volume.
Check if you have set a maximum level for volume adjustment.
|D. LED INDICATORS|
The connection and operation status can be checked through the colours and patterns of the LED indicators on the top panel of the Primary Speaker.
