The Marmitek Split 418 UHD is an active 1-input / 8-output HDMI splitter for distributing the same audio and video signal from a single HDMI source to eight displays simultaneously. It is suited to presentation environments, multi-room installations, and any setup where one source must reach multiple screens at the same time.

Unlike passive splitters, the Split 418 UHD actively amplifies the signal to maintain image quality at all eight outputs without degradation. It supports Ultra HD 4K (4k2k@24/30), Full HD 1080p, and all 3D formats. The EDID switch allows independent selection of video resolution (4k2k, 1080p, 1080i) and audio format (HD Audio, DTS 5.1, Dolby Digital, PCM 2.0) for the HDMI output. The interference-free solid metal casing adds structural durability.

Key Features

• 1 HDMI input, 8 HDMI outputs — simultaneous signal distribution to eight displays
• Supports Ultra HD 4K (4k2k@24/30), Full HD 1080p, and all 3D formats
• EDID switch for independent video resolution and audio format selection per output
• HDCP 1.4, CEC, EDID, DVI, Deep Color (36-bit), x.v.Color compliance
• Video bandwidth: 10.2 Gbps, clock frequency: 300 MHz
• Maximum HDMI cable length: 15 m per output

• Supports LPCM 7.1, DTS-HD Master Audio, Dolby TrueHD, DTS, Dolby AC-3, and 2.0CH audio

Product Benefits

• Eight simultaneous outputs make the Split 418 UHD appropriate for commercial presentation rooms, sports bars, hotel lobbies, and multi-zone home cinema installations
• Active signal amplification maintains consistent image quality at all eight outputs regardless of the display at the end of each run, up to the 15 m per-output cable limit
• The EDID switch resolves compatibility mismatches in mixed-resolution installations, letting each output negotiate an appropriate resolution independently
• The solid metal casing resists electromagnetic interference from nearby equipment, which is especially relevant in rack-mounted AV installations
• Support for DTS-HD Master Audio and Dolby TrueHD ensures lossless audio is delivered to all connected displays without downmixing

Why You'll Love It

• Eight outputs eliminate the need to daisy-chain multiple two-output splitters, which would introduce additional latency and potential signal degradation at each stage
• The EDID switch gives granular control over each output's resolution and audio format, making it straightforward to accommodate a mix of older and newer displays in the same installation
• The solid metal build makes the Split 418 UHD suitable for permanent rack installation alongside other AV equipment, with no risk of housing flex or connector loosening over time
• One power adapter and one source cable feed the entire eight-output distribution, keeping the source equipment area tidy with minimal cabling
