Kramer amplifies and extends 4K

Kramer has focused on 4K distribution with the latest additions to its range. The PT-3H2 is an active range extender while the VM-2H2, VM-3H2 and VM-4H2 are all distribution amplifiers.
The PT−3H2 is a 4K@60Hz (4:4:4) equaliser and line driver for HDMI 2.0 and HDCP 2.2 signals. The unit extends the range when using long HDMI cables. More specifically, this is 10m to input, 10m from output, total 20m at 4K60 (4:4:4); 25m to input, 15m from output, total 40m at 4K60 (4:2:0); 30m to input, 15m from output, total 45m at 1080p60.

Moving on to the distribution amplifiers, the family has almost identical vital statistics with one key difference. All of the units offer a maximum data rate of 17.82Gbps and a maximum resolution of 4K@60Hz (4:4:4). In terms of signal transmission, each unit delivers an HDMI 2.0 and HDCP 2.2 compliant signal, supporting deep colour, x.v.Color, lip sync, 7.1 PCM, Dolby TrueHD, DTS–HD, CEC (OUT 1 only), 2K, 4K and 3D. They equally all offer Kramer intelligent EDID processing, I–EDIDPro, Kramer Equalisation and re-Klocking technology, Force RGB and selectable HDCP authorisation. The area where the units differ is the number of outputs. The VM-2H2 takes one HDMI input, equalises and reclocks the signal and distributes it to two identical outputs. For the VM-3H2, this is three outputs and the VM-4H2 follows the same process for four outputs.
