AV-transmitter Kramer Electronics PT-3H2

PT−3H2 is a compact AV transmitter and HDMI 2.0 line driver designed to equalize and extend 4K HDR signals with HDCP 2.2 support. It supports a maximum resolution of 3840 x 2160 (4K@60Hz) with 4:4:4 chroma and a bandwidth up to 18 Gbit/s. The unit is HDTV compatible and implements HDMI standards including HDR10, HDCP 2.2 and HDMI 2.0, with support for ARC and CEC.

Advantages

The device provides signal equalization and reclocking to preserve image quality over long HDMI runs and includes an external power supply option. Its small form factor (50 x 26 x 15 mm) makes it easy to install in confined spaces or integrate into AV racks and distribution setups. The PT-3H2 extends HDMI range reliably while maintaining HDR and HDCP compliance.

Suitable for (tasks / use cases)

• Extending HDMI connections for 4K@60Hz displays
• Professional AV installations and presentation systems
• Home theatre setups requiring HDR10 and HDCP 2.2 support
• Situations with long HDMI cable runs where signal integrity must be preserved

How to use

Connect the source device to the PT-3H2 input and the display to the PT-3H2 output using HDMI cables. If running long cable runs, place the unit near the midpoint or at the transmitter end according to the required input/output cable lengths to meet the stated range figures. Provide power via the optional external power supply when required by the installation to ensure stable operation and signal reclocking.

Recommendations

For best performance at 4K@60Hz (4:4:4), use high-quality HDMI 2.0 cables and keep the input and output cable lengths within the specified ranges; use the external power option in installations with marginal cable lengths or where maximum signal integrity is needed.
