IQMDA40
12G/3G/HD-SDI UHD-4K Down Converter & Distribution Amplifier
The IQMDA40 is a 4K UHD quad- or single-link high-quality downconverter and distribution amplifier able to distribute a 12G SDI input to three outputs, while converting it for HD/SD simulcast or monitoring applications. It also includes a 12G/quad-link SDI 4K UHD frame synchronizer and processing for the downconverted channels with powerful picture enhancement tools. High Dynamic Range and Wide Color Gamut support allows S-Log3, HLG or PQ 4K UHD feeds to be integrated into an SDR workflow.
A variable aspect ratio converter with reading and writing of WSS, VI and 2016 AFD signaling, video processor and legalizer are also included.
Audio handling includes channel routing,...
