BAL hum eliminators upgraded

BAL Broadcast has extended its range of broadcast hum and noise eliminators by the addition of a product suitable for use in serial digital high definition systems.
Interconnects in a High Definition Broadcast chain can result in ground loops and the introduction of induced noise. Even though SDI in more immune to extraneous noise and low frequency component (hum) problems can still exist as often seen in a smearing of the eye pattern. As with analogue signals once there is noise in the system it is extremely difficult and costly to remove.
Jitter caused by induced noise effects can compound other system problems and result in the loss of a recoverable digital signal. HD-SDI serial digital signals transmissions at 1.485Gb/s over a cable contain a range of frequencies and are subject to analogue type distortions, like induced noise, as well as digital distortions related to sampling and quantizing. Unlike analogue systems the digital signals do not degrade gracefully but are subject to a knee effect and sudden crash. Using the HD-SDI Ground Loop Eliminator the potential for this type of data loss can be greatly reduced. The four transmission rates of SMPTE 259m and SMPTE 292 1.485 Gb/s HD SDI are supported. The device is housed in a metal box fitted with BNC connectors.
Power is not required so making it convenient to insert in any position within a cable run. Hum Eliminators and Isolation Transformers are also available for standard SDI, S-Video, Analogue Composite, Analogue Component and audio.
