Installation
- As an active speaker, the IMAGE requires its own power supply. To do this, connect your IMAGE speaker to your
power outlet with the delivered power plug.
- The fabric cover can be easily attached or removed.
- The IMAGE is only suitable for wall mounting. Before mounting, make sure the wall on which the IMAGE is to be
mounted is strong enough to support the unit. In case of doubt, please contact a specialist. To attach the IMAGE to
the wall it is necessary to mount two suitable brackets (screws or similar) at a distance of 34 cm from the wall. First
connect your IMAGE to the power before you hang it on the wall, as this is more difcult to do afterwards.
Connecting external audio sources
The IMAGE wall speaker has both a digital and an analog connection to play audio signals.
Digital input with PROLOG
For maximum performance and lossless digital signal transmission, it is recommended to use a PROLOG Control Unit
(PROLOG 2, PROLOG 8) as source. To do so, connect your IMAGE speaker to your PROLOG with an XLR audio cable. The
PROLOG 2 offers streaming (Bluetooth, AirPlay® and DLNA), an optical digital input (TOSLINK) as well as analog inputs
(RCA) with a high-quality analog-to-digital converter.
Analog input
External, analog devices can be connected to the analog XLR input of the device.
Switching the inputs
Switching the inputs is not necessary with the IMAGE. Both input signals (analog and digital) are played automatically.
Be careful not to accidentally play multiple sources at the same time.

Integrate PROLOG into your home network
The easiest way to integrate the PROLOG into your home network is to use a Ethernet connection with your
network. Use the Ethernet connection on the back of the device. Your PROLOG will appear as a DLNA and
AirPlay® speaker in your network after a few seconds.
If you want to connect the PROLOG wirelessly to your own network, you can do this with the “AirLino®“-App:
1. Install the AirLino®-App which can be downloaded on the Apple App Store or Google Play Store
2. Activate WiFi on your device
3. Search for the WiFi-network “PROLOG“ and connect to it
Note: If your PROLOG is already integrated in your home network, you must connect to your home network.
4. Open the AirLino®-App. The setup wizard will start automatically
5. You can choose a custom name for your PROLOG to recognice the device easier in the future
6. Choose your home network name and enter the correct password of the network
The AirLino®-App will now try to connect your PROLOG to the home network
Note: If the device is not ready after 60 seconds there might occured an error. Please check if you entered the
correct network password and try the setup again. In some cases it is useful to unplug your PROLOG and try all
steps again after at least 10 seconds.
7. If the setup was successfully, your PROLOG is visible in the network. You can now see your PROLOG in your audio
streaming device.
8. Enjoy the music through your IMAGE
Note: Please make sure that the WiFi connection and the signal are stable and strong enough to manage high quality
audio signals in your home network. Low quality WiFi routers might cause problems. Please contact a wireless network
specialist if problems occur.
Streaming - wireless music playback with PROLOG 2
In combination with the PROLOG 2 you can stream music from a variety of sources wirelessly to the IMAGE wall speakers.
For this you need a wireless connection from your audio source (smartphone, tablet, etc.) to the PROLOG 2. The built-in
Bluetooth, AirPlay® and DLNA audio-receiving components start automatically and are ready after a short while. Then
connect to your smartphone, laptop, iPod touch, or similar device as follows:
Establish Bluetooth connection
1. Activate Bluetooth in the settings of your audio source (e.g. smartphone, tablet)
2. Search for “PROLOG“
3. Connect with “PROLOG“ like any other Bluetooth device
4. Make sure (in the settings of your audio source) that the audio signal is played via your Bluetooth connection
5. Enjoy the music through your IMAGE wall speakers
Note: When Bluetooth is activated once again, the device will automatically connect to the PROLOG 2 as soon as the
PROLOG 2 is within range.
Note: Not every device supports Blutooth apt-X. Therefore, the sound quality might differ.

Pairing the remote control
At factory settings, the remote control is not paired with the PROLOG 2. If you have several remote controls of the same
type, pairing is useful to avoid conicts.
1. Use a pen or a straightened paper clip to press the pairing button on the back of the PROLOG
2. The device is now in pairing mode for 30 seconds
3. Now press any key on the desired remote control (e.g. the “Mute“-key)
4. The device is now paired with this remote control and accepts only commands from this remote control
Note: If the PROLOG 2 does not receive any command from a remote control during the 30 seconds it is in pairing mode,
the pairing is canceled and the PROLOG 2 accepts commands from any remote control of the same type.
Wake-up function
In case of inactivity, the IMAGE automatically activates the standby mode after a while to avoid unnecessary power
consumption. The automatic wake-up functionality automatically reactivates the IMAGE wall speaker when there is
an incoming audio signal. Accordingly, the loudspeakers can remain permanently connected to the power connection
without affecting the energy consumption or the lifetime of the product.
Sound optimization
In order to achieve an optimal sound experience, it is advisable to observe the following points:
- Mount your IMAGE wall speakers on the wall - they are designed and optimized for this application.
- Your IMAGE wall speakers offer a unique, lossless music reproduction – especially in combination with a PROLOG.
It is therefore advisable to play high-resolution music les or uncompressed formats (such as WAV or Apple
Lossless).
- Make sure your room has adequate acoustic damping. Too much reverb negatively affects the music signal.
Curtains, upholstered furniture or carpets can support good room acoustics and contribute to a pleasant damping.
- For the best possible sound quality, the entire signal routing should be digital. Use the digital audio input of your
PROLOG to attach various sources and connect the IMAGE and PROLOG via the digital XLR connectors. This
ensures lossless signal transmission.
Note: There are no rules that apply to all environments. Nevertheless, it is advisable to consider the above points.
Saftey instructions
Please observe the safety instructions when using the IMAGE, otherwise warranty claims may expire.
- Do not expose to rain or moisture. There is a risk of re and the risk of damage.
- Do not use near liquids (bathtub, etc.).
- Do not place burning objects (candles, etc.) next to or on the speaker.
- Do not place near heat sources.
- Use only with original manufacturer accessories.
- Do not connect the speaker during thunderstorms.

is a risk of electrical shock. All necessary repairs are to be carried out exclusively by a service partner or
manufacturer, otherwise the guarantee and warranty claim expires.
Maintenance
The IMAGE is maintenance-free. Clean the surface only with a soft dry to slightly moist cloth or a feather duster. Do
not use scouring powder, alcohol, gasoline, polish, wax or other similar liquids. Do not set up the IMAGE in a humid
environment. Frequent temperature changes, humidity and excessive sunlight will damage the speaker and may alter
its appearance. If the speaker is destroyed by improper use, contact the manufacturer and nd out about repair options.
The speaker membrane should not be touched.
