How do I set up LS50 Wireless II?

A Wi-Fi network is required for initial setup. Download the KEF Connect App from the App Store or Google Play Store and install it on your mobile device. Follow instructions in the app to get the speakers connected (onboarded) to your Wi-Fi network.

What should I do if I cannot find my LS50 Wireless II in the network during set-up?

Make sure your device, speakers and router are within sight. The speakers broadcast on Channel 2 (2.4 GHz band). If your router overlaps this channel, it may cause issues. Go to your router settings and configure the 2.4 GHz channel to avoid overlap.

What router specifications does LS50 Wireless II support?

IEEE 802.11a/b/g/n/ac, IPv4, IPv6, Dual-band 2.4 GHz / 5 GHz

For better streaming stability, especially on hi-resolution music files, a 5 GHz Wi-Fi network with a router transmission speed of at least 1300 Mbps is recommended.

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.

Wired: Cable length up to 10 meters

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.
