• For 1080p resolution, fi rst make certain that the input cable is as short
as possible and none of the output cables are more than 30 meters
long. HDMI cable design and quality are extremely important in long
cable runs where capacitance can severely effect performance. Our
1391A Extender/DDC Corrector may be a necessary accessory to use
in extreme length applications.
• Make certain that the Distribution Amplifi er is receiving power by
looking at the power LED. It should be illuminated and not fl ickering
on and off. Intermittent operation generally means a problem with the
DC power adapter or low AC voltage being applied to the DC adapter’s
input.
• If you still experience problems using the distribution amplifi er, you
should attempt to determine what is wrong by fi rst attaching the source
device directly to each of the destination devices in turn using the
same cables you are using with the expanded system. This is a way of
determining if the problem is due to bad cables or a problem with the
other devices. If you are unable to obtain a signal using this simplifi ed
path, suspect the cables, the source device or the destination device.
• Remember that HDMI devices communicate with one another so the
source device and all destination devices must be fully HDMI capable.
In addition, HDCP encryption requires processing dependent on the
equipment you have connected to both the source and destination
devices.
