9878 & 9880 OPTIONAL RECEIVERS
In addition to the two 9879 wallplate/receivers (shown on page
one) that come with each 9870D system, Audio Authority offers the
option of using the 9878 dual-gang, stainless steel wallplate (left)
or the enclosed 9880 receiver (right). The three can be used in any
combination with each other.
DUODRIVE SYSTEM OVERVIEW
The 9870D is comprised of
the Model 9871 RCA-to-Cat 5
Driver and the Model 9879
wallplate. These products enable
distribution of audio, video and
IR control signals on Cat 5 cable
runs of up to 1,000 feet. The
buffered Cat 5 bus outputs on
each 9871 drive one or two 9879
wallplates.
To expand output capacity of
the system, connect together an
unlimited number of Drivers using
an Audio Authority Kit 46. The
9879 offers a wallplate/receiver
form factor to fit a standard
single-gang electrical box. DC
power for each wallplate is
supplied through the Cat 5 cable
from the 9871’s power supply.
In addition to its Cat 5 outputs,
the 9871 RCA bus output may be
used as a pass-through output
for a nearby HDTV and/or home
theater.
