Introduction

Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront the video, audio, presentation, and broadcasting professional on a daily basis.

Achieving the Best Performance

• Use only good quality connection cables (we recommend Kramer high-performance, high-resolution cables) to avoid interference, deterioration in signal quality due to poor matching, and elevated noise levels (often associated with low quality cables).

• Do not secure the cables in tight bundles or roll the slack into tight coils.

• Avoid interference from neighboring electrical appliances that may adversely influence

signal quality.

• Position your Kramer VP‑427H2 away from moisture, excessive sunlight and dust.

This equipment is to be used only inside a building. It may only be connected to other equipment that is installed inside a building.

Overview

Congratulations on purchasing your Kramer VP‑427H2 4K HDBaseT Receiver/Scaler.

VP‑427H2 is a high-performance receiver/scaler for extended-reach HDBaseT twisted pair,

HDMI™, bidirectional RS-232 and IR signals. The unit receives an HDBaseT signal that it converts to HDMI and passes Ethernet, IR and RS-232 signals. It also de-embeds and outputs an unbalanced stereo audio signal, and up- or down-scales the picture to match the resolution of the HDMI monitor.

VP‑427H2 is housed in a compact, Kramer MegaTOOL™ enclosure which can be mounted

side by side in a 19-inch rack adapter.

VP‑427H2 provides exceptional quality, advanced and user-friendly operation, and flexible

control.

Exceptional Quality

• Max. Output Resolution (HDMI) – Up- and down-scales to any resolution. (Maximum resolution: 4K@60Hz (4:4:4)).

• Max. Input Resolution (HDBaseT) – HDBaseT input resolution up to 4K@60Hz (4:2:0).

• Supports HDMI 2.0 and HDCP 1.4 / 2.2.

• Audio Support – Embedded and analog (supporting LPCM 2CH) for the output.

• HDBaseT Data Tunneling – Supports Ethernet tunneling, as well as bidirectional

tunneling for RS-232 and IR control.

• On-Screen Display (OSD) – For easy setup and adjustment, accessible via the front-panel buttons.

• Constant Sync – Maintains sync on the output, even if the input video signal is lost or interrupted.

• System Range – Up to 100m (328ft) at 4K.
