An upgrade of the previous OREI HDA Audio extractors, the new HDA-912 4K supports higher video resolutions like 4K50/60Hz, 4K 30hz, 1080P 3D and 1080P120HZ. Mathias Vanwolleghem is at Institut d'Electronique de Micro-electronique et de Nanotechnologie, CNRS, Université Lille 1, 59650 Villeneuve d'Ascq, France,Ĭhristopher R. OREI HAD-192 4K is one of the best Extractors designed to output audio signals from any compliant HDMI source to digital-analog or optical stereo output. 1 Opto-isolators prevent high voltages from affecting the system receiving the signal. With no parallel limiting resistor, the feedback may approach an open circuit condition at maximum gain. An opto-isolator (also called an optocoupler, photocoupler, or optical isolator) is an electronic component that transfers electrical signals between two isolated circuits by using light. When used in the feedback loop, Figure 1c, a fixed resistor should be used in parallel.
