The Professional HDMI 2.1 Cable with detachable MPO fiber optic technology (HDMI fiber optic cable) sets new standards in digital signal transmission for 10K Ultra HD. It is excellently suited for professional installations and home theater systems that require lossless, high-resolution image transmission with data rates up to 48 Gbps. As an ideal solution for connecting devices with HDMI 2.1 interfaces over long distances, it supports 10K video formats with up to 120 Hz and HDR (High Dynamic Range). Even with extremely long transmission paths up to 100 m*, the fiber optic cable guarantees optimal performance. A special feature is the professional and compact MPO connector system (Multiple-Fiber Push-on/Pull-off), which allows for convenient installation through conduits (minimum inner diameter 16mm). The transmission direction can be flexibly changed by swapping the HDMI-MPO adapters.The source-side HDMI-MPO adapter is powered through the HDMI interface, while the display-side adapter uses a free USB port or a separate USB power supply (not included) for power.This cable offers the highest image and sound quality for demanding AV transmissions in professional and high-end home applications. *Lengths up to 100 m are available upon request. Outstanding video and audio quality – even across long distances: This HDMI 2.1b fiber optic cable was specifically developed for high-quality, professional applications where maximum transmission performance over long distances is essential. Ideal for: High-end home cinema setups Gaming events AV installations with HDMI networks Digital signage & large-format displays Important note: No ARC / eARC support. This cable does not support Audio Return Channel (ARC / eARC). This means audio cannot be sent back from the TV to an AV receiver or soundbar – for example, when using integrated TV apps or built-in DVB-T/C/S tuners. Audio transmission from the source to the TV, however, works flawlessly and in the best possible quality. Click here for application examples, FAQs, etc.

The LS-404 Micro AIR is a further installment in the success story of the Micro AIR technology: As with the already legendary AIR Helix cables, air is also a central component of the insulation concept in the Referenz Micro AIR technology. Due to the low speaker impedances, however, low line resistances and a low inductance are also very important for speaker cables. For this reason, the Referenz LS-404 Micro AIR uses a total of 8 concentric copper conductors in addition to the air dielectric. Thanks to this multicore architecture, the magnetic fields of the positive and negative conductors overlap and neutralize each other. This significantly reduces the inductance of the cable, which guarantees unaltered transmission of the audio signal over a broad frequency spectrum. Due to our approach, the LS-404 has an extremely balanced sound character with precise timing, on top of a solidly controlled foundation. This cable is primarily designed for full-size floorstanding loudspeakers. The impression sound makes on the listener is always subjective, of course, and depends in no small part on the overall constellation of a hi-fi system. In the end, the decisive factor is your own personal listening impression. Click here and discover the exciting details

Because the outputs on hi-fi devices only supply extremely weak signals and are sensitive to high cable capacitance, the capacitance of a cable plays a significant role when connecting components together. A “low-pass filter” can be created that cuts off high frequencies and also causes phase shifts. This is the reason why RCA and XLR audio cables are ideal companions for the air-based insulation used in the MICRO AIR technology. Another special feature of the NF-204 Micro AIR is its symmetrical architecture, which guarantees high immunity to EMC radiation. Alone or in combination with the LS-204/LS-204-XL, the NF-204 Micro AIR opens up the connection floodgates and allows your components to perform at their very best.

Because the speaker cable carries the largest current in the entire device chain, a suitable conductor cross-section is required to transport it with as little loss as possible. This current generates correspondingly strong magnetic fields and, since it is alternating current, there is a frequency-dependent resistance in the inductance of the cable. Low inductance is therefore particularly important for speaker cables - and this is precisely what has been achieved with the LS-1205 Air: The cable's inductance value has been reduced by a particularly ingenious arrangement of the conductors, the 4-fold "multicore" structure, enabling it to behave in a completely sound-neutral way over a wide frequency range. In addition, the magnetic fields generated around the individual conductors overlap and neutralize each other. This means that all frequencies are transported unhindered and without any time delay, enabling a fabulously open and detailed musical presentation. At the end of the air helix, the LS-1205 Air’s four conductors are separated into so-called aluminum splitters for the receiving connector. In the area between the splitters and plug, in-akustik uses highly flexible molded parts made of a special elastomer. These parts are fixed inside the splitter using a specifically designed plastic plug. This means that the cable remains reliably flexible in the connection area as well. The molded parts run right to the front of the connectors and enclose their inner workings - which underscores the sleek yet attractive design of the LS-1205 Air.
