Kramer SG_B00CQCQ4M8_US PT-571 HDMI Twisted Pair Transmitter

The Kramer PT-571 is an HDMI-over-twisted-pair transmitter that converts an HDMI source signal into Kramer's DGKat format for transmission over a single shielded twisted pair cable — extending the reach of HDMI from its practical limit of approximately 15 feet to a full 100 meters (330 feet). At 1.65 Gbps data rate, it carries uncompressed 1080p at 60Hz with full HDCP and EDID signal integrity intact. EDID pass-through is the technically critical feature that separates professional AV extension hardware from consumer-grade solutions: by maintaining the EDID handshake across the cable run, the PT-571 ensures the source device reads display capabilities correctly and outputs the appropriate resolution automatically, eliminating the resolution negotiation failures that are endemic to passive HDMI cable extensions or lower-tier extenders.

This unit targets professional AV installation scenarios where a display, projector, or digital signage screen must be positioned significantly farther from the source than HDMI cable can reliably span — conference rooms, lecture halls, retail signage, and hospitality AV systems. The single-cable twisted pair infrastructure is cost-efficient at installation scale compared to fiber optic alternatives, and the DGKat format maintains signal fidelity at the full rated distance without the compression artifacts associated with some HDBaseT implementations. The key pre-purchase constraint is the proprietary ecosystem requirement: the PT-571 requires the matching Kramer PT-572+ receiver, and the 1.65 Gbps bandwidth specification limits it to 1080p content exclusively — installations requiring 4K signal distribution will need a different product tier entirely.
