Inakustik Premium II 48G 2m

Certified Ultra High Speed by the HDMI organization, this Inakustik cable from the Premium range complies with the HDMI 2.1b standard and supports a maximum bandwidth of 48 Gbit/s. It is designed to ensure the transmission of audio and video signals that meet the specifications of HDMI 2.1-compatible equipment. The cable features OFC copper conductors, triple shielding, and gold-plated connectors.

Architecture designed for digital signals

The internal structure of the Premium II 48G is based on high-purity OFC (Oxygen Free Copper) conductors, assembled in twisted pairs with a 28 AWG gauge. This configuration limits electromagnetic interference between the various data lines. The triple shielding, a combination of a metal braid and two layers of foil, reinforces insulation against external interference, whether from Wi‑Fi signals, radio waves, or electrical noise from nearby devices.

The connectors feature 24‑carat gold plating that prevents oxidation and maintains optimal conductivity over time. A braided fabric sheath covers the whole assembly, offering better mechanical resistance than a simple plastic jacket. However, the cable’s rigidity, a consequence of this robust construction, requires a fairly generous bending radius when installing it behind furniture or a wall-mounted TV.

High-definition video and smooth gaming

With 48 Gbps of bandwidth, the cable supports the most demanding resolutions: 4K at 120 Hz with 4:4:4 chroma subsampling, 8K at 120 Hz with DSC (Display Stream Compression), and even 10K at 60 Hz in 4:4:4 HDR via DSC. For more common setups, 4K/60 Hz passes easily without any compression.

Gamers will appreciate compatibility with VRR (Variable Refresh Rate), which synchronizes the display’s refresh rate with that of the console or PC to eliminate screen tearing. ALLM (Auto Low Latency Mode) allows the TV to automatically switch to game mode when a console is detected. QMS (Quick Media Switching) and QFT (Quick Frame Transport) round out this feature set by reducing latency when changing sources or content.

HDR support includes HDR10, HDR10+ and Dolby Vision formats, covering most of the catalogs offered by streaming platforms and Ultra HD Blu-ray discs.

Multichannel audio and enhanced return channel

The Premium II 48G carries uncompressed HD audio streams: Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio, and DTS:X are sent directly to the receiver or soundbar. The eARC (Enhanced Audio Return Channel) function can send these same formats from the TV’s built-in apps to an external audio system, without the need for an additional optical cable.

CEC (Consumer Electronics Control) compatibility lets you control multiple devices with a single remote, while HDCP 2.3 ensures decoding of protected content, including that from the latest video-on-demand services.
