Connections
6.5 Speaker Cable Gauge
PowerZone Connect speaker connection
cable gauge should be chosen
appropriately to reect the type of
installation. The adjacent tables specify
the appropriate cable gauge for less than
0.5dB cable loss with different installation
types and cable lengths.
6.5 GPIO Connections
If any PowerZone Connect GPIO
functionality is required, cables will need
to be connected to the supplied GPIO
connector. Connecting cables to the GPIO
connector is illustrated in Diagrams 6d.
Note: The GPIO GPO connection has an
output impedance of 1kΩ. Connected
devices must be able to sink 3.3mA. Shielded
cables should be used.
Conguring GPIO functionality is
described in Section 5 of this manual.
6.6 Network Connections
PowerZone Connect ampliers are
TCP/IP network connected devices
that are congured via a web page
based interface. Wired (Ethernet) and
wireless (WiFi) connection options
are available. Connecting PowerZone
Connect ampliers to a TCP/IP network is
described in Section 5 of this manual
