in-akustik home theater cables bring cinema-scale picture and sound into your living room. The range is built around HDMI: from Ultra High Speed HDMI 2.1 cables for 8K, including optical fiber versions for long cable runs, down to proven High Speed and Standard HDMI models. Designed by in-akustik, every cable relies on consistent shielding to keep video and audio signals free from interference. HDMI splitters, switches, and (e)ARC audio extractors complete the setup for projectors, receivers, and TVs.
HDMI splitter 1 > 2 high-speed scaler
The integrated scaler allows old and new devices to be combined and provides the appropriate format for each of them. This means a new 4K-capable TV actually receives a 4K format, even if an older Full HD TV is connected to the splitter in parallel. The intelligent EDID management (EDID engine) automatically generates the EDID data required for the source. The splitter therefore ensures that the connected devices always achieve their maximum potential.
HDMI high-speed splitter 1 > 8
This HDMI splitter simultaneously distributes picture and sound from an HDMI source (e.g. Blu-ray player, PS5 or similar) to up to eight displays (e.g. LED/plasma TV or projector). The splitter is HDMI 1.4 compatible and can handle all popular HDMI formats thanks to its high bandwidth of up to 10.2 Gbps. These include 3D and Full HD 1080p as well as the new high-resolution 4K x 2K format. The intelligent EDID management system (EDID Engine) automatically generates the necessary EDID data for the best picture and sound quality on the connected devices. It also ensures that all displays are able to play back images and sound at the same time.
High-speed splitter 1x HDMI > x2 HDMI
The Star HDMI splitter distributes an HDMI source (e.g. set-top box or DVD player) to two displays (e.g. LCD or plasma panels). The splitter is HDMI 1.3 compatible and supports all common formats. For long cable lengths, we recommend using the power supply unit included with the splitter.
MHL-HDMI switch 3 > 1
MHL (Mobile High-Definition Link) is the name of the new AV interface for mobile devices. Smartphones and tablet PCs that support this standard use their micro USB port for this purpose. With the appropriate adapter, this interface allows picture and sound to be played back in HD quality on a TV with HDMI input. The Premium MHL/HDMI Switch Box has an integrated MHL adapter. Smartphones and tablet PCs can be connected to the MHL input on the front of the unit, provided they support the MHL standard. The switch also has three HDMI inputs that can handle all common HDMI formats.
Wireless HDMI Kit
The Exzellenz Wireless HDMI Kit | 3D transmits picture and sound signals wirelessly up to 30m*. The kit supports Full HD, 3D and multi-channel audio formats. The set consists of a transmitter and a receiver, which are connected to the source or TV via the HDMI interface. For convenient control, commands from IR remotes can be transmitted back to the source via the return channel and the supplied IR sensors. The transmitter also has an HDMI output with a loop-through function. A TV can be connected here in parallel, close to the source, for example. In this case, the set works like an HDMI splitter. Transmitter and receiver are supplied with power via micro USB sockets using the power supply units provided. Alternatively, they can be powered via free USB sockets, e.g. on the Blu-Ray player or TV. However, this requires USB-A to Micro-B cables (not included) and the USB socket used must supply at least 1A. *Depending on the structural circumstances and the EMC load in the immediate surroundings. Typical range under real-world conditions is about 10m.
Home theater: Your path to the perfect film and sound experience at home
Popcorn and nachos at home
Having your own dream home theater is more than just a luxury – it's a gateway to unforgettable entertainment experiences right in your own four walls with a real cinema atmosphere. With the right home theater accessories, you can transform your living room into a place where films, series, and games come to life. Technology has made enormous strides in recent years, and the possibilities for creating a professional cinema experience at home are more diverse than ever. From high-resolution projectors and TVs to powerful sound systems, the world of home cinema offers the right solution for every requirement and budget.
TVs and projectors – the heart of your home theater
The foundation of any home theater is a good display device. Modern TVs with OLED or QLED technology offer an impressively high resolution with deep blacks and vivid colors. For a true cinema experience, projectors are the first choice, as they can project images over 100 inches onto your wall or screen. Depending on the size of your room and the lighting conditions, you can choose between different models to best suit your needs
HDMI cables – the invisible heroes
Often underestimated, but crucial to the success of your home theater setup, are high-quality HDMI cables. They transmit both video and audio signals between your devices and should therefore be chosen carefully.
Modern Ultra High Speed HDMI cables based on the HDMI 2.1 specification support resolutions up to 10K at 120 Hz as well as dynamic HDR formats such as HDR10+ and Dolby Vision. Thanks to their increased bandwidth of up to 48 Gbit/s, they ensure lossless transmission even with the most demanding content, such as high-frame-rate gaming or next-generation movie formats.
A well-shielded, precisely manufactured HDMI cable prevents signal loss, jitter, and interference – guaranteeing razor-sharp images, exact color gradients, and precise sound synchronization. Whether for your 4K TV, 8K projector, or future-ready 10K display: using certified Ultra High Speed HDMI cables ensures your system is prepared for the highest performance.
HDMI 2.2 – What’s new
The upcoming HDMI 2.2 standard further refines the capabilities introduced with HDMI 2.1. It is designed to deliver even more efficient bandwidth management, improved data integrity, and expanded support for new audio-video formats. Key enhancements include higher refresh rate handling beyond 120 Hz, optimized latency for real-time applications such as gaming and VR, and enhanced synchronization features for variable refresh rate (VRR) and quick frame transport (QFT).
HDMI 2.2 will also focus on smarter device communication, enabling seamless integration with AI-based image optimization and future HDR standards. While HDMI 2.2-certified devices are still emerging, cables designed to meet or exceed HDMI 2.1 Ultra High Speed specifications will remain fully compatible.
Sound components: The acoustic experience
Speakers – The voice of your home theater
An impressive picture deserves equally impressive sound. Speakers allow for a variety of configurations, from simple 2.1 systems to full surround sound like 7.2.2 or 9.1.4. Choosing the right speakers depends on your room size, budget, and personal preferences. Floor-standing speakers typically offer the fullest sound, while compact bookshelf speakers are more flexible in terms of placement. For the ultimate cinema sound, consider adding a powerful subwoofer to deliver the deep bass you can not only hear but also feel.
Amplifiers – The heartbeat of your home theater
A high-quality amplifier is crucial for the sound quality in your home theater. It amplifies the audio signals and ensures that your speaker system can deliver its full potential. Modern amplifiers offer a variety of connections and support advanced audio formats such as Dolby Atmos and DTS:X. When choosing an amplifier, make sure it has enough power for your speakers and that it has the latest connections and technologies.
