Introduction
The award winning Mini-TX UHD is the world's smallest ultra-low latency UHD wireless video transmitter on the
market, measuring just 85mm long by 56mm wide and 28mm deep. It can transmit in two entirely different
frequency bands via its software-defined radio, offering complete on-site spectrum flexibility without the need for
changeable radio modules. But, even with its compact size, the Mini-Tx UHD includes all the features expected
from a traditional wireless video transmitter, and more, with pre-distortion, GPS, Wi-Fi, and a 3-axis accelerometer
as standard and a dual UHF receiver to add robustness and flexibility to the camera control.
The Mini-Tx UHD also includes changeable connector panels for different applications, like a single UHD/HD video
input, Quad HD/Single UHD inputs or Quad HD with power and control over SDI. Additional features available with
the Mini-Tx UHD include video formats up to 2160p59; HEVC and AVC video encoding at 8/10-bit 4:2:2/4:2:0; up
to 32 Mbps video bitrate per pedestal; four channels of embedded SDI audio; two channels of analogue MIC/Line
selectable audio with MIC phantom power; MPEG1L2 audio encoding; support for HDR; and Tx frequency options
from 1.4 to 7.5 GHz. The transmitter also allows power and BSI data to be transmitted over SDI (HD only).
