5 Configurations
Before making input, output and GPIO connections, an initial Inca 500 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 Inca 500 amplifiers are connected to mains power and network
services. These connections are described in the following two sections.
5.1 Mains Power Connection
Inca 500 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.
Inca 500 amplifiers have no mains power switch and are operational as soon as mains
power is connected.
5.2 Network Services
Inca 500 amplifiers are configured via a web page interface called. Before the configuration
menus can be accessed, Inca 500 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 an Inca 500 amplifier to a TCP/IP network using a wired connection (Ethernet)
follow the steps below.
1. Use an Ethernet cable to connect the Inca 500 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 Inca 500 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 Inca 500 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.
4. Open a laptop or desktop web browser and enter the address http://192.168.64.100. The
Inca 500 Web App interface will open to enable amplifier configuration as required.
Note: Inca 500 amplifiers can be configured to use DHCP for network connection if
required. However, if an Inca 500 amplifier using DHCP is power cycled, it is possible that
the TCP/IP network router will assign it a dierent 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.
