2A
`Hold the wall mounts in place at the desired mounting point and mark the four
drill holes required.
`Please use wall mounting template for the distance between the two wall mounts.
`Drill the holes. To do so, use an appropriate drill bit for the respective surface
(dia. 6 mm, depending on the wall type).
`Push the wall plugs (M6 x 26) into the drill holes.
`Screw four screws into the drill holes. Leave the screw heads protruding from the
wall by approx. 2mm.
`Place the wider part of the wall mounts on the screw heads, then gently press

Also comply with the information in the user manual for the device you
want to connect to the soundbar.
7.1. Connecting audio devices via AUX IN
7.1.1. Audio cable with 2 x 3.5 mm diameter jacks
connect an output device to the soundbar using the headphone output socket on
the output device.
`Set the output device to a medium volume level and then switch it o.
`Insert the jack plug into the soundbar’s AUX IN socket.
`Insert the other jack plug into the headphone output socket on the output
device.
7.1.2. Audio cable with cinch plugs
You will need an audio cable with cinch plugs, 1 x 3.5 mm jack -> 2 x cinch (not
supplied) to connect an audio device to the soundbar using the cinch outputs on
the audio device.
`Set the output device to a medium volume level and then switch it o.
`Insert the jack plug into the soundbar’s AUX IN socket.
`Insert the red and white cinch plugs at the other end of the cable into the

DE
EN
FR
NL
IT
ES
Devices such as stereo receivers or televisions usually have one red and
one white audio output socket. These are usually marked as OUT, AUDIO
OUT, LINE OUT or similar.
7.2. Connecting audio devices via the optical
connection
You can connect digital ampliers or televisions with an optical digital output to
the soundbar via the OPTICAL connection. To do this, you will need an optical
digital cable (supplied）
`Set the output device to a medium volume level and then switch it o.
`Plug the optical digital cable connector into the OPTICAL connection socket on
the soundbar.
`Plug the other optical digital cable connector into the corresponding digital
output socket on your output device.
If no sound is output, switch the audio output format on your output
device to PCM (Pulse Code Modulation) mode.
7.3. Important information regarding HDMI CEC/
HDMI ARC
7.3.1. HDMI CEC (Consumer Electronics Control)
CEC enables all devices connected via HDMI to communicate with each other. This
connection then means that you can use the remote control for your television, for
example, to adjust the volume on your device or mute it.
In order to use HDMI CEC functions, all components connected must support HDMI
CEC. The name and range of functions may vary depending on the manufacturer. To
this end, please note the information in the user manual for the device in question.
All HDMI cables that support HDMI 1.3 standard or later also support HDMI CEC.
7.3.2. HDMI ARC (Audio Return Channel)
Using ARC means not only that audio signals are received via HDMI, but that these
signals can also be sent back along the same cable.
In order to use HDMI ARC functions, all components connected must support HDMI
ARC. In addition, you will need at least one “High Speed” HDMI cable (version 1.4 or
later, supplied).
