HEC-5000 Circuitry

Features for HEC-5000
  • 5 Channels of Hum Reduction
  • 100 MHz Bandwidth
  • Low Signal Loss
  • No Gain or Phase Distortion
  • Passive Device, Failure Free
  • Easy-to-Use
The HEC-5000 now joins other multi-channel hum eliminators manufactured by Allen Avionics. Like the HEC-3000, which provides 3 channels of hum reduction, and the HEC-4000 that provides 3 channels of hum reduction plus 1 channel of transformer isolation, the HEC-5000 hum eliminator stops all 50 Hz or 60 Hz hum. The HEC-5000 is designed to eliminate hum in video applications caused by long cable runs or ground loops.

This newest addition has a bandwidth of over 100 MHz per channel, making it suitable for most HDTV applications and many video projection systems with 100 MHz bandwidth. The HEC-5000  has channels for Red/Y, Green/CB, Blue/RC, H.Sync and V.Sync.
