Allen Avionics HEC-4000 Overview

  • 1Description
  • 2Four Channels of I/O
  • 3High dB Isolation Between Channels
  • 4Connector Protection

Hum eliminators work best when interference causes small differences in ground potential (less than 20 VDC) or long cable runs have induced currents. HEC series units also work well when there are multiple power panels in a building that create differences in ground potential which induce ground loop current flow and 60 Hz hum.

Four Channels of I/O

Four input channels give this hum reducer the ability to pass GBR and YUV component signals plus sync.

High dB Isolation Between Channels

Up to 80 dB of isolation between channels is used while passing a full component signal; this ensures the same quality of hum reduction as the single channel HEC series while still maintaining separate channel integrity.

Connector Protection

Featuring 1/4 inch stainless steel guard rails to protect connectors in the field or studio mounted.
