When it comes to wireless sound, your KEF speakers are like a high-performance car. Designed by engineers obsessed with precision, they deliver an incredible audio experience. Whether you’re watching TV, gaming or playing records, the right cable connection allows your LS50 Wireless II speakers to immerse you in superb soundscapes.
01. Transform your TV experience
Televisions are getting thinner. But your sound shouldn’t. LS50 Wireless II is the perfect companion for your set-up. The latest generation Uni-Q drivers create a wide, dynamic sound stage to deliver rich dialogue and explosive sound effects. HDMI ARC (Audio Return Channel) and CEC (Consumer Electronics Control) allow all the sound from your TV’s connected devices to be played through your KEF speakers. You can also control the sound with your TV’s remote control.
With most modern TVs, you can use an HDMI cable. Connect your HDMI cable to the ARC/eARC port of your TV. On the back panel of the primary speaker, use the HDMI input, marked TV (V). Then, select “TV” mode in your KEF Connect app. You can also turn on “TV” mode with the source button on the top panel of the primary speaker or on the remote control. The TV icon on the top panel stays lit when the connection is successful.
Set up and sit back
You may need to adjust the settings on your television, so check the manual. Keep in mind some TV manufacturers use different names for HDMI ARC and CEC connections (for example: Anynet+ or Simplink). You can follow similar steps to use optical or coaxial cables. For all of these, it’s important to set the audio output format to PCM 2.0 (some TVs will just state PCM) – not Dolby or Bitstream.
02. Step into a new world
Game designers create immersive worlds for players to escape to. From the rumble of a V8 engine to the clinking of a bullet casing dropping to the floor, sound matters. It can make you feel the expanse of an endless horizon or the squeeze of a dark, damp dungeon. Your speakers place you in the heart of the action.
03. For the record lovers
If you love the warmth of records, LS50 Wireless II will fill your home with that fluid feel of analogue sound. It will stay true to the original recordings – that crackle of a bygone era.
Make sure you have a phono stage in the chain. Some turntables have one built in, others require a separate one. You’ll need an analogue stereo cable with a 3.5mm jack on one end to connect your turntable/phono stage to your KEF speakers. The turntable end most commonly needs to have stereo RCA connections.
Expert tip: The analogue input is converted to digital, allowing all your analogue sources to benefit from the same Digital Signal Processing (DSP) wizardry applied to the digital inputs, maximising both the performance and the experience.
04. Go deeper with a subwoofer
With a subwoofer, you’ll get that deep, low bass. That rumble. That extra impact. Subwoofers help you really feel the sound whether you’re listening to music or enjoying a movie. Just imagine watching Jaws without those ominous notes rising from the sonic depths.
KEF has developed a wide range of subwoofers to suit all tastes and rooms. Discover more here.
[O] Optical input jack: Plays audio (e.g. Blu-ray player, cable box) through an optical cable. Maximum resolution : 96kHz/24 bit. (Connector also referred to as TOSLINK.)
[C] Coaxial digital cable: Plays audio (e.g. audio player) through a coaxial / RCA cable. Maximum resolution: 192kHz/24 bit.
[X] Auxiliary input jack: Plays audio from an analogue source (e.g. turntable) through a 3.5 mm audio cable.
[T] Primary/Secondary connection port: Connects the primary and secondary speakers with the inter-speaker cable.
[S] Subwoofer output jack: Connects a subwoofer to the speakers through an RCA cable.
[E] Service port: This is specifically for our technicians to use when servicing your speakers.
[N] Network port: Connects the speakers to a router with a LAN cable. Maximum resolution: up to 384kHz/24bit.
[A] AC input connector: Connects the speakers to the power source with the power cables.
We don’t recommend doing so. While most TVs have Bluetooth, the delay can be significant. Some TVs also feature a lip sync setting, but these tend to delay the audio to match the lagging video.
