Overview

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.

Pros & Cons

👍 Pros

  • 100-meter transmission range over a single twisted pair cable eliminates the multi-cable runs or active repeaters required by standard HDMI at distances beyond 15 feet
  • HDCP pass-through ensures protected content from Blu-ray and DRM sources transmits without handshake errors that plague lower-grade extension solutions
  • EDID pass-through enables automatic source-to-display resolution negotiation across the extended signal path, preventing manual resolution forcing at the source
  • 1.65 Gbps data rate supports uncompressed 1080p at 60Hz — the full bandwidth demanded by professional AV presentation and digital signage sources at 1080p
  • Single twisted pair cable infrastructure significantly reduces installation material cost compared to fiber or multiple-cable HDMI solutions for long runs

👎 Cons

  • 1.65 Gbps bandwidth ceiling makes the PT-571 incompatible with 4K or HDR signal formats — this is strictly a 1080p-era extension device
  • Requires matching Kramer PT-572+ receiver — no cross-brand compatibility means the full solution cost requires sourcing both units from Kramer's ecosystem
  • DGKat is a proprietary Kramer signal format, not the open HDBaseT standard, which limits long-term flexibility if infrastructure needs to support third-party AV equipment
  • No power-over-cable (PoC) functionality is confirmed for this model, meaning the receiver end requires independent power sourcing
  • At a professional AV price point, this unit addresses only signal extension — switching, scaling, and matrix routing require additional upstream hardware

Frequently Asked Questions

The PT-571 supports signal extension up to 330 feet (100 meters) over a single twisted pair cable using Kramer's DGKat technology. The cable type used affects performance — Kramer recommends their DGKat-compatible shielded twisted pair cables for reliable transmission at full rated distance.
The PT-571 is designed to work with the Kramer PT-572+ (or compatible DGKat receiver). It is not a universal HDBaseT transmitter and will not pair with arbitrary twisted-pair receivers from other manufacturers. This is a proprietary signal format — both transmitter and receiver must be matched Kramer DGKat units.
Yes. The specifications confirm HDCP signal pass-through. This means copy-protected content — Blu-ray, streaming sources, and DRM-protected corporate AV sources — will transmit through the extension link without triggering HDCP handshake failures, which is a common point of failure in lower-quality HDMI extension solutions.
The PT-571 supports data rates up to 1.65 Gbps, which is sufficient for uncompressed 1080p at 60Hz (which requires approximately 1.5 Gbps). It will not support 4K/UHD resolutions — those require HDMI 2.0 bandwidth of 18 Gbps, far beyond this unit's specification. This is a 1080p/1.4-era device.
Yes, EDID pass-through is confirmed. EDID (Extended Display Identification Data) is the communication protocol through which a display tells a source device what resolutions and formats it supports. Without EDID pass-through, the source (computer, media player, etc.) cannot identify the display and may default to a mismatched resolution or fail to output signal entirely. The PT-571's EDID handling ensures the source and display negotiate correctly across the extended run.
