T
he Model 9870D DuoDrive
™
incorporates the key signal paths necessary for
premium home audio and video entertainment systems. Consisting of one 9871
Driver and two 9879 wallplate/receivers, the DuoDrive distributes component video up 
to a resolution of 1080p, as well as both digital and analog audio, over two inexpensive, easy-to-install CAT 5 cables from a single 
source to two remote locations. The DuoDrive is easily expandable in increments of two outputs by adding additional 9870Ds. 
Audio Authority’s unique cable length compensation also allows adjustment for the optimal signal strength at any distance up to 
1,000 feet from the source, faithfully preserving the signal’s original color and detail for maximum enjoyment.
• Distribute audio and video to multiple areas 
 of the home over CAT 5 cables
• Single-source/two output distribution, 
 expandable in pairs with additional modules
• Distributes HDTV component video, digital 
 audio, and analog audio.

Each of the two Model 9871 
Driver outputs works over a pair 
of inexpensive, easy to install 
Cat 5 cables. The wall-mountable 
9870D system accepts digital and 
analog audio, and HD component 
video inputs.
The Cat 5 outputs from a Model 9871 driver terminate 
at 9879 wallplate/receivers, (or 9880 self-enclosed 
receivers) which provide a remote connection point for 
an HDTV video and/or audio sound system. The active 
circuitry in the wallplates is powered through the Cat 5 
bus, so no power connection is required at the remote 
zone. Each receiver can be adjusted to compensate 
for the cable length up to 1,000 feet. Component 
video, digital and analog audio signals are carried on 
two Cat 5 cables to each wallplate/receiver. A control 
signal pathway for a 3rd party IR remote system is also 
part of the Cat 5 bus. This pathway allows the desired 
source to be selected remotely via IR.
