alphatronics SL-Line+

One for all

With the new models of the SL-Line+, alphatronics introduces the next improved generation of mobile smart TVs. The SL-Line+ is available from 22 to 40 inches. Whether it's a motorhome, caravan, or camper van: there's space for your new SL-Line+ in all vehicles.

The heart of alphatronics devices bearing the abbreviation "DW" is the operating system. For this purpose, we rely on webOS Hub in the next phase of expansion. This brings a host of new features, including PVR recording, Timeshift, Apple AirPlay 2, and Apple HomeKit integration. The webOS Hub operating system offers a wide range of applications (via Content Store) and stands out for its simple and particularly intuitive use. To ensure that all televisions are always up to date, updates are regularly provided via OTA (Over-The-Air).

The SL Line+ is available in screen sizes of 22", 24", 27", 32" and 40". It is equipped with a triple tuner (DVB-S/S2, DVB-T/T2, DVB-C), HbbTV, CI+ (new 2.0 standard), DVD player (slot on the right side of the unit), 2x USB port, 2x HDMI™ port, Bluetooth® 5.0, as well as a new light wave port (SPIDF / Toslink), which enables connection to digital soundbars or hearing aids.

Product Information


New Design with illuminated logo

Discover the elegance of alphatronics SL-Line+! True to our motto "Big in Detail," we continuously evolve our products, crafting them with sophistication and timelessness. In this model year, we have further optimized the devices of the SL-Line+ with an almost frameless casing, high-quality materials, and proven quality, giving them a new design. As a special highlight and eye-catcher, these models now feature an illuminated front logo, which can be dimmed or completely turned off in three levels using a switch on the bottom

Intuitive operation through webOS Hub

More intuitive, faster, smarter - In order to make our TV sets even more intuitive to operate, we have decided to use the well-known webOS Hub operating system. This enables us to further develop the alphatronics quality we have been accustomed to up to now in the user interface (UI) as well. The centerpiece of alphatronics devices with the abbreviation "DW" is the operating system. In the next expansion stage, webOS Hub is being used. This brings a wealth of new features, including PVR recording, Timeshift, and Apple AirPlay 2.


PVR Recording function and Timeshift

Design your TV program according to your preferences and your own schedule. Thanks to the PVR recording function and the intuitive program manager, recordings can be scheduled easier than ever before. This is particularly advantageous on the go, where fixed broadcast times are often difficult to adhere to. In areas with limited live TV reception, the recording function provides a reliable way to enjoy independent entertainment. Connect an external hard drive for the PVR recording function (we recommend an SSD hard drive with a maximum of 1TB).

With the Timeshift function, the program can be paused and played back at a later time.

Apple AirPlay 2

In a time where the connection between smartphones and TV sets is becoming increasingly important, we are proud to offer you Apple AirPlay 2 with our new TV devices. Immerse yourself in the world of seamless connectivity and discover the Apple universe in a completely new way. With AirPlay 2, the connection between your smartphone and your television is easier than ever before. You can transfer and display photos, music, or videos directly from your Apple device to your TV.

Whether you want to showcase your latest vacation photos or enjoy your favorite music in the best quality, Apple AirPlay 2 makes it possible.


Ideal for working from anywhere

Why not turning your alphatronics TV into a screen?

Our TV devices offer various options to make mobile working in your vehicle even more convenient:

Connections and Second Screen: Our TV devices come with two USB and two HDMI ports. This allows you to easily connect a keyboard, mouse, and other accessories to your television. Use your alphatronics TV either wirelessly (Windows+K) or traditionally via an HDMI™ cable as a second screen.

Support for USB Webcams: Currently, models C920, C922, C925, and C930 from the manufacturer Logitech are supported.

Eye Care: Activate the blue filter to reduce eye strain, especially during longer screen sessions.

Useful family mode

Do you use the built-in family mode and ensure harmonious television usage even while traveling?

This mode includes the following options:

Maximum Volume Mode: Limit the volume level to prevent hearing damage, especially when using headphones.

Usage Limits: Here, you can set the times and duration for which the TV device can be used.


100% Pixel error free panel

Since an optimal image is important to us, every panel is tested to be 100% free from pixel defects. With this, we guarantee our customers the best possible TV experience even when they are on the move.

Shortcuts to Netflix and Amazon Prime Video

Easily access Netflix and Prime Video thanks to the designated buttons and enjoy your favorite programs.


External antennas

Another highlight of the SL Line+ are the external antennas with SMA connection. Sometimes, even small things can create big differences. The external antenna can increase reception performance by up to 15% compared to an antenna built into the unit.

Integrated DVD player

For situations where streaming is not reliably available or there is no reception (DVB-T, SAT, WIFI), all models with the abbreviation "DW" feature a side-mounted slide-in DVD drive. This allows you to enjoy your favorite movies and series on DVD even while on the go.


Turn your smartphone into a remote control

With the "LG ThinQ" app, you can also operate your TV via your smartphone. This is available for all Android and iOS-based devices (via the respective store). Various features are available via the app, such as a digital remote control, switching the unit on/off via the smartphone, and sharing the screen, pictures or videos on the TV.

With the help of the integrated CI+ slot, you can decrypt and receive modules as well as cards from corresponding pay TV providers. To do this, simply insert the Smart Card (including module) into the CI+ slot of your alphatronics television set.


Bluetooth® version 5.0

With the alphatronics Bluetooth® version 5.0 module, the TV set can not only send the sound signal via Bluetooth® , but also play music from the mobile phone via the TV. Thanks to the Bluetooth® standard 5.0, Bluetooth® end devices can now connect to the TV even faster. Further advantages include improved connection stability and low power consumption.

Function "Enjoy Sound together"

The audio standards in the reception area and streaming, featuring Dolby Atmos, DTS, or 5.1 Surround Sound, are continuously expanding. Alphatronics TV devices have also been enhanced with a digital optical connection (also known as SPDIF or Toslink). This allows you to connect your soundbar or hearing aids with the best transmission quality. The audio signal is transmitted losslessly to the connected device via an optical cable. Additionally, our "DW" or "W" models offer the new feature of "Enjoying TV sound together". The sound can be played simultaneously through the integrated speakers and a connected Bluetooth® headset at different volume levels.


HDMI CEC & ARC Function

All units with the new operating system support full HDMI CEC (for controlling other devices) as well as ARC for playing sound on external devices. This allows, for example, a soundbar with HDMI™ input, a console or an Android stick to be connected and controlled via the TV's remote control.

Triple Tuner (DVB-S/S2, DVB-T/T2, DVB-C)

Are you already using a satellite dish, a DVBT antenna or do you not yet know how you want to equip your vehicle? Thanks to the integrated triple tuner, you have a mobile TV for all types of reception. You can also use the campsite's cable TV via DVB-C.


OTA – Over the Air Update

Always up to date thanks to updates via the Internet. All models with webOS Hub as an operating system benefit from regular updates as well as permanent feature upgrades. Our tip: Activate "automatic software updates" in the TV settings and let the TV set do the rest itself.


Delivered with one terrestrial aerial AN-5

Active DVB-T antenna for indoor use with integrated low-noise amplifier, HDTV compatible. Magnetic base for easy attachment. Low power consumption as the power is supplied directly from the TV's USB port.

The quality of alphatronics
