5.4. Remote Audio Input Connections
The HUB1616 / HUB1408 has 8 control ports (REMOTE INPUTS) with RJ45 connector,
for the connection of eMCONTROL1 type remote control panels. Each of these ports,
besides providing DC power and establishing the digital communication bus with the
remote panels, has a mono audio input, balanced and with line level, considered a
remote
input
of the HUB unit. In this way, it is possible to expand the number of audio inputs of
the equipment with these 8 remote inputs, in addition to the local inputs available through
audio connectors on the rear panel of the matrix.

Connecting a balanced mono audio signal to a REMOTE port of a HUB device is done as
follows:
•
Live or direct signal
>
Terminal 8 of the RJ45 connector
•
Cold or inverted signal
>
Terminal 7 of RJ45 connector
•
Ground
>
Terminal 6 of RJ45 connector
If an eMCONTROL1 type remote panel is used to control an area of the installation, the
eMCONTROL1 panel itself has an internal connector to receive the audio signal from an
adjacent and complementary panel, such as the WPaMIX-T in the pair of the example
below. This type of configuration is ideal to have zone control and remote audio from the
zone itself: a single standard CAT5 cable, connected between the eMCONTROL1 panel
and a REMOTE port of the HUB unit, is used to carry out the exchange of DC power,
digital control data and remote audio signal, physically entered in the eMCONTROL1
complementary panel, to the HUB unit.
