Isolation Transformers

A range of high quality passive signal isolation transformers for digital audio and video signals. The range includes;
6G-SDI Isolators, 3G-SDI Isolators, HD-SDI Isolators, SD-SDI Isolators, ASI Isolators, MADI Isolators and AES3 Isolators.

The Isolation transformers are used for providing the reduction and elimination of hum and noise caused by differences in ground potential, especially those above 20 volts, or induced currents in long cable runs. As a result, these ground problems manifest themselves as signal noise on the digital video transmission.

Hence, the resultant common mode noise causes degradation of the bit timing of the high speed digital signal leading to bit errors. a consequence of the bit errors is a  reduction of the quality of the video and data content within the transmission signal. Digital signals do not degrade gracefully as they often suffer from a cliff-effect causing the signal to be lost altogether.

However, the singular most common symptoms of hum in digital signals is intermittent horizontal black streaks. These streaks are often one line in thickness.

Installing an isolation transformer is crucial in implementing ground protection. This occurs when ground or earth potential differences are in existence between equipment. As a result, permanent damage to video equipment is often the consequence. Damage of this nature is not only costly but, crucially, could also take a video signal off-air.
