6. There is no sound from the Secondary Speaker.
• Make sure the Secondary Speaker is connected to power.
• Check if the connection between the two speakers is lost (the LED indicator light of
the Primary Speaker is blinking white and blue).
If the connection is lost, short press the P/S pairing button (P) on the back panel of
the Primary Speaker to re-establish the connection. Wait a while until the connection
is established.
Note:
Do not press the button for more than 1 second.
• If the problem persists, connect the speakers with the inter-speaker cable and turn on
Cable Mode in the KEF Connect App.
7. There is dropout from the Secondary Speaker.
• If the speakers are connected wirelessly, try to move them closer to each other.
• If the problem persists, connect the speakers with the inter-speaker cable and turn on
Cable Mode in the KEF Connect App.
• A congested network or multiple wireless devices lead to high interference. Try to
minimize the interference around the speakers.
8. The audio is out of sync with the picture when using the speakers with a TV.
• If available, try the video delay/lip sync function of your TV.
• Use HDMI/optical input, and try to avoid Bluetooth connection. There is an inherent
delay in the Bluetooth codec.
9. 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 LED indicator light of the Primary Speaker is blinking light blue, the HDMI
connection is not found. In this case, make sure that the HDMI cable is connected to
the ARC port of the TV.
If the LED indicator light of the Primary Speaker is pulsing light blue, 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. 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 LED indicator light of the
Primary Speaker illuminates light blue briefly and then fades out (both CEC and
ARC connections are now established).
