A longitudinal stop-coil, for reducing induced main-frequency hum in medium-length co-axial circuits, such as video feeds. This is a portable design, housed in a standard Canford extruded box with…
These analogue video isolators are useful in both broadcast and CCTV applications, where there are differences in earth potential between video circuits, such as between different locations on a…
LL1575 The LL1575 is a high-bandwidth transformer designed for CCTV (closed circuit television) use, but can be useful in certain broadcast applications. It can be used where there are differences in…
Hum, the term for low-frequency noise induced by power-supply alternating currents, can present problems in even the best designed audio and video installations. These accessories may become …
BAL HD-SDI-HUM High Definition Hum Eliminator SDI and HD-SDI signals suffer less from extraneous noise and low frequency hum problems than do analogue video signals. However, within complex broadcast…
Blocking DC currents while remaining transparent to PAL and NTSC video signals, these transformers balance ground potential and eliminate hum interference. 'Severe' interference caused by 50 or 60Hz…
