4. Installation
Note: The rack mounting and desk/wall mounting components
described and illustrated in Sections 4.1 to 4.3 are not supplied
with PowerZone Connect ampliers but are available to purchase as
accessories. Contact your amplier re-seller for more information.
4.1 PowerZone Connect Mounting
The PowerZone Connect ampliers are shipped without rack
mount hardware attached but can be congured for rack
installation using one standard rack ‘ear’ and one half-rack
extension piece as illustrated in Diagram 3a. The installation
and equipment rack should be congured to provide
appropriate ventilation airow space around the sides and
rear of the amplier as illustrated in as illustrated in Diagram
1a. Ventilation airow space of at least 25 mm (1 in) should
be maintained along at least one side of the amplier at all
times. Ventilation apertures are also located on the rear panel
of the amplier and must not be obstructed. It is important to
retain at least 80 mm (3.1 in) free space for airow behind the
amplier rear panel.
In addition to rack mount ears, optional rack mount rear
support hardware is available and can be attached to the
amplier. Rear support hardware may be appropriate if
the amplier is to be used in a mobile rack or potentially be
subject to signicant movement. Diagram 3b illustrates the
use of rack mount rear support hardware.
Multiple PowerZone Connect ampliers can also be
mechanically connected using accessory connecting plates.
Diagram 3c illustrates the use of connecting plates.

4.2 Free-standing
If not installed in an equipment rack, PowerZone Connect
ampliers can be placed free-standing on a at surface.
Adhesive rubber feet are supplied for this purpose.
PowerZone Connect ampliers can also be attached
to the underside of desks or wall mounted using
connecting plate hardware. The adhesive rubber
feet should also be used in these circumstances
to minimise the possibility of vibration between
the amplier and mounting surface. Wall and desk
mounting is illustrated in Diagrams 4a and 4b.
It is important in any free standing installation that
airow through the amplier’s side panel mounted
fans and rear panel ventilation apertures is not
compromised by adjacent items. At least 80mm of
free space behind the amplier and 25mm along at
least one side should be retained at all times. Mounting Plate +

Conguration
5. Conguration
Before making input, output and GPIO connections, an
initial PowerZone Connect DSP amplier conguration
should be established. It is particularly important that
the output amplier format is congured appropriately
for the speakers that are to be connected.
Conguration requires that PowerZone Connect DSP
ampliers are connected to mains power and network
services. These connections are described in the
following two sections.
5.1 Mains Power Connection
PowerZone Connect ampliers incorporate a power factor
corrected power supply and can be used with mains input
voltage from 100V AC to 240V AC, 50/60Hz. Use the mains
cable supplied with the amplier and connect it to a switched
mains supply.
PowerZone Connect ampliers have no mains power switch
and are operational as soon as mains power is connected.
5.2 Network Services
PowerZone Connect ampliers are congured via a
web page interface called PowerZone Control. Before
the conguration menus can be accessed, PowerZone
Connect ampliers must be connected to the same TCP/
IP network as the computer or mobile device that is to
be used for conguration access.
Wired (Ethernet) Network Connection
To connect a PowerZone Connect amplier to a TCP/IP
network using a wired connection (Ethernet) follow the steps
below.
1. Use an Ethernet cable to connect the PowerZone Connect
amplier rear panel Network Control socket to a free socket on
a network router or network switch.
2. With the PowerZone Connect amplier connected to mains
power, wait for the front panel Network indicator to illuminate
green to indicate that the amplier has been assigned an IP
address.
3. Use a network scanner app to identify the IP address
assigned by the network router to the PowerZone Connect
amplier.
4. Open a computer or mobile device web browser and enter
the IP address identied in the Step 3 above. The amplier
conguration web page interface will now open.
Note: If a PowerZone Connect amplier is power cycled it is possible
that the TCP/IP network router will assign it a different IP address,
leaving its conguration page inaccessible via the previous address.
If this occurs, a network scanning app can be used to identify the
new IP address. Alternatively, the amplier can be congured to use
a xed IP address via the LAN conguration menu.
Wireless (WiFi) Network Connection
To connect a PowerZone Connect amplier to a TCP/IP
network using a wireless connection (WiFi) follow the steps
below.
1. With the PowerZone Connect amplier connected to mains
power, wait for the front panel WiFi indicator to illuminate
green.
2. Use a mobile, laptop or desktop device to search for available
WiFi networks. Connect to, PowerZone Connect (product
serial number)’ using the password, ‘password’. The amplier
serial number can be found on its rear panel.
3. Open a computer or mobile device web browser and enter
the IP address: 192.168.4.1. The amplier conguration web
page interface will open.
4. Select the Settings tab followed by WiFi > WiFi Mode >
Client to congure the amplier to connect to the required
WiFI network. The WiFi network name and password will be
required.
It is strongly recommended that the PowerZone Connect
amplier Access Point WiFi password is changed following
initial wireless connection.
Conguration
5.3 Conguration Menus
Opening a web browser that is network connected to a
PowerZone Connect amplier initially displays PowerZone
Control Web App Dashboard screen illustrated in Diagram
5a. The Dashboard is the ‘home’ screen from which all other
conguration options can be accessed.
The Dashboard screen shows the amplier status and output
zones on the right and the conguration menu access tabs on
the left. The functions available under each tab are as follows.
Input Tab
The Input Tab provides naming, mono/stereo selection,
sensitivity, and gain trim for each amplier input channel. An
internal pink noise source, provided for system testing and set
up, can also enabled or disabled and adjusted for gain via the
Input Tab.
Zone Tab
The Zone Tab enables installation zones to be dened and
named, and provides access to further sub-menus. Zones
might be bar or restaurant areas for example, or different
rooms in a home. For all Zone Tab menus, the installation zone
under conguration is selected by highlighting one of the zone
identiers (A, B, C or D) at the top of the page.
• The Source menu option enables inputs to be assigned to
installation zones.
• The GPIO Volume Control option enables external volume
control to be applied to individual installation zones. The
GPIO conguration menu can be found under the Settings
Ta b .
• The Compressor option enables default or custom signal
compression to be applied to individual installation zones.
Note: Compression can be useful to reduce the volume difference
between loud and quiet audio material. The lower the compression
threshold is set, the more the difference between loud and soft will
be reduced. The overall zone volume may need to be increased
when compression is used. The default compression parameters are
appropriate for most installations.
Output Tab
The Output Tab enables amplier outputs to be named and
provides access to further sub-menus. For all Output Tab
menus, the amplier output under conguration is selected by
highlighting one of the output identiers (1, 2, 3 or 4) at the top
of the page.
Note: The number of individual outputs available for conguration
will depend on the PowerZone Connect amplier model and the
input, zone and output mode conguration.
• The Routing menu enables zones to be assigned to amplier
outputs.
• The Delay menu enables delay to be applied to individual
amplier outputs.
• The Equalizer menu enables parametric equalization to be
applied to individual amplier outputs. Equalizer settings
congured for one amplier output can be copied and
applied to other outputs.
• The Crossover & Gain menu enables high or low-pass
crossover lters and gain adjustment to be applied to
individual amplier outputs. Crossover lter settings
congured for one amplier output can be copied and
applied to other outputs.
• The Speaker EQ menu enables parametric
equalization to be applied to individual amplier
outputs following the application of crossover
ltering. Equalizer settings congured for one
amplier output can be copied and applied to other
outputs.
• The Driver Alignment menu enables delay to be
applied to individual amplier outputs following
the application of crossover ltering.
