Audio Authority 1391A
HDMI ver. 1.3 Extender w/ DDC Correction
Audio Authority 1391A HDMI ver. 1.3 Extender w/ DDC Correction
By installing the 1391A HDMI ver. 1.3 Extender w/ DDC Correction near the HDMI input, cable runs of up to 40 meters (130 feet) are now possible! If you have experienced HDCP handshake problems while trying to use inferior extenders, the 1391A has the performance you need! For example, if you have existing HDMI cables that just can't quite handle the highest HDTV resolutions, the 1391A can solve that problem in a matter of minutes!
Like most Audio Authority products, the 1391A comes with a one year limited warranty from the manufacturer.

A Better Extender through DDC Correction
Many mysterious handshake problems occur due to corruption of the DDC (Display Data Channel), yet many HDMI extenders
simply pass through this information without conditioning it. The 1391A actively preserves DDC information by compensating
for skew, impedance, and capacitance - all factors that can cause errors in long cable runs. It also equalizes the
high speed video channels to insure the perfect image transmission expected when using HDMI.
What is the Data Display Channel (DDC)?
Along with other responsibilities, the DDC handles the critical "key exchange" between HDCP sources. If this connection
is not constantly maintained, image drops and loss of handshake will occur, resulting in static or no picture. Even if the
video signals are completely intact, a failed DDC communication channel will result in no HDCP handshake, and therefore no picture.
Greater Reliability
Most other products designed to extend HDMI over long cable runs rely on the power supplied by the source over the HDMI
cable's built-in 5V rail. This is strictly prohibited by the HDMI specification - and for good reason! This 5V power
rail was intended to initialize the hot-plug detection circuit on the downstream HDMI devices (display, AV Receiver, etc.),
and if the full voltage is not present, the HDCP handshake cannot initialize.
The 1391 is powered by a separate, external power supply to ensure solid reliability and excellent performance, in total compliance with HDMI specifications.

Using the 1391A Extender/DDC Corrector
The Model 1391 reconstitutes the HDMI signal at the end of long cable runs, just before the display input. The maximum
cable length from the source to the 1391 input is 40 meters. The cable length from the 1391A output may be up to 5 meters
using premium cables. In some cases, more than one 1391A can be used in a single cable run, but this configuration is not recommended.
