5. Configuration
Before making input, output and GPIO connections,
an initial UXA4401 amplifier configuration should
be established. It is particularly important that the
amplifier output format is configured appropriately for
the speakers that are to be connected.
Configuration requires that UXA4401 amplifiers are
connected to mains power and network services. These
connections are described in the following two sections.
5.1 Mains Power Connection
UXA4401 amplifiers 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 amplifier
and connect it to a switched mains supply.
UXA4401amplifiers have no mains power switch and are
operational as soon as mains power is connected.
5.2 Network Services
UXA4401 amplifiers are configured via a web page
interface. Before the configuration menus can be
accessed, UXA4401 amplifiers must be connected to the
same TCP/IP network as the computer or mobile device
that is to be used for configuration access.
5.2.1 Wired (Ethernet) Network Connection
To connect a UXA4401 amplifier to a TCP/IP network using a wired
connection (Ethernet) follow the steps below.
1. Use an Ethernet cable to connect the UXA4401 amplifier rear
panel Network Control socket to a free socket on a network router
or switch, or directly to an Ethernet equipped laptop or desktop
computer.
2. Connect the UXA4401 amplifier to mains power using the
supplied mains cable. Wait for the front panel Network indicator
to illuminate green to indicate that the amplifier has network
connectivity.
3. The UXA4401 amplifier default LAN IP address is 192.168.64.100.
Configure the laptop or desktop computer for a fixed IP address
in the same IP range; eg. 192.168.64.10, with Subnet mask of
255.255.255.0 (or prefix 24) and set the Gateway to 192.168.64.1.
Configuration
4. Open a laptop or desktop web browser and enter the address
http://192.168.64.100. The UXA4401 Control Web App interface
will open to enable amplifier configuration as required.
Note: UXA4401 amplifiers can be configured to use DHCP for network
connection if required. However, if a UXA4401 amplifier using DHCP is
power cycled, it is possible that the TCP/IP network router will assign
it a different IP address, leaving its configuration page inaccessible via
the previous address. If this occurs, a network scanning app can be
used to identify the new IP address. DHCP and Fixed IP address option
settings can be found in the Settings Tab menu described in Section
5.3.
5.2.2 Wireless (WiFi) Network Connection
To connect a UXA4401 amplifier to a TCP/IP network using a
wireless connection (WiFi) follow the steps below.
1. With the UXA4401 amplifier 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, UXA4401 (product serial number)'
using the password, 'password' . The amplifier 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 UXA4401 Control Web App interface
will open to enable amplifier configuration as required.
4. Select the Web App Settings Tab followed by WiFi > WiFi Mode
> Client to configure the amplifier to connect to the required WiFI
network. The WiFi network name and password will be required.
It is strongly recommended that the UXA4401 amplifier
Access Point WiFi password is changed following initial
wireless connection.
