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. |
