Amtune Single-Cable Solutions for USB-C Meeting Rooms

The meeting table has been quietly rewired. Where a credenza once held a tangle of HDMI, DisplayPort, analogue audio and power adapters, the 2026 expectation is a single USB-C cable: plug in a laptop and video, audio, USB peripherals, control and charging all travel down the same run. The design community has noticed. In the 2026 Pro AV awards cycle, an extension system that simultaneously carries 4K120Hz HDMI or USB-C video over DisplayPort Alt Mode, USB 3.2 Gen 1 data, RS-232 control and up to 60W of power delivery across 100 metres was singled out for praise — specifically because its point-to-point architecture requires no network configuration or IP expertise.

The engineering reality behind that simplicity is demanding. Copper HDMI is reliable for only a handful of metres, so anything beyond the credenza needs extension. USB is far less forgiving than video: data links that behave over a two-metre cable often collapse over thirty unless the extender is designed for USB 3.2 specifically. HDCP and EDID must be preserved end to end or the source refuses to hand over the picture, and a display that reports the wrong capabilities will quietly downgrade a 4K laptop to 1080p. Power delivery adds a fourth constraint, because a dock that cannot charge the laptop creates its own support ticket. Get any one of these wrong and the room feels broken even though every component is technically in specification.

Amtune addresses the room as a chain rather than a box. The AV converter range handles format and connector translation at the source, including USB-C, HDMI, DVI, SDI and HDBaseT. AV extenders then carry high-definition video, audio and control data over Cat cable and fibre while preserving EDID and HDCP behaviour, with Power-over-HDBaseT available where an outlet behind a display is impractical. Where several sources share a room, the AV switch family provides dependable routing and the HD video seamless hybrid matrix adds glitch-free switching with HDMI, DVI, SDI, HDBaseT and fibre inputs. For larger estates, AV-over-IP codecs and decoders extend the same philosophy across the campus network.

The outcome for integrators is a shorter bill of materials, fewer cables to dress and a room that behaves the same way for a visiting presenter as it does for the resident team. Because the entire chain comes from a single manufacturer, EDID, HDCP and control behaviour can be validated as a system rather than patched together in the field, and OEM and ODM programmes are available for partners who need specific connector sets, form factors or branding.
