1. Product Introduction
The PT-MA-HDBT42 is a four-input by two-output matrix switcher with two HDBaseT
inputs, two HDMI inputs and two HDBaseT + HDMI outputs. The switcher transmits
4K video to distances up to 131 feet (40 meters) and 1080p video to distances up to
230 feet (70 meters) over a single CATx cable. The HDBaseT inputs and outputs
support 48V Power over Cable (PoC) feature, allowing the compatible transmitters
and receivers to draw their power from the matrix over the CATx cable.
The matrix supports downscaling so a 4K video input can automatically be down
scaled to a 1080p output when connecting a display that only supports resolution
up to 1080p. Moreover, the matrix switcher features comprehensive EDID
management and advanced HDCP handing to ensure maximum functionality with a
wide range of video sources. The switcher offers IR, RS232 and TCP/IP control
options.
1.1 Features
4x2 matrix switcher with HDBaseT inputs and outputs.
Fully compliant with the HDMI V2.0 and HDCP 2.2.
Supports video resolution up to 4K@60Hz 4:4:4, HDR10, Dolby Vision.
Supports auto-switching.
Features two mirrored HDMI outputs for two HDBaseT outputs, and all outputs
support 4K to 1080p down-scaling.
HDBaseT inputs and outputs support 48V PoC, allowing the transmitters and
receivers to draw their power from the matrix switcher over CATx cables.
Visually lossless video de-compression and compression for HDMI signals
transmission up to 40m at 4K and 70m at 1080p on HDBaseT inputs and outputs.
Supports Stereo + SPDIF audio outputs for audio de-embedding.
Controllable via front panel buttons, RS232, IR and TCP/IP (built-in GUI).
