Installation Notes
- High or low impedance speaker connection options can be selected independently for each output channel via the amplifier configuration web interface.
- Analogue input sensitivity can be adjusted independently for each channel via the amplifier configuration web interface.
- S/PDIF digital audio I/O routing can be configured via the amplifier configuration web interface.
- GPIO (General Purpose Input/Output) options can be configured via the amplifier configuration web interface.
- Ensure that rack or other confined installation does not restrict the airflow required for safe and reliable operation of the equipment. It is important to ensure that the 40°C maximum operating temperature for the equipment is not exceeded.
Wireless Network Control Connection
A mobile, laptop or desktop device with WiFi functionality and a web browser
is required.
Follow the steps below.
- Connect the CXA amplifier to mains power using the supplied mains cable and wait for the front panel WiFi indicator to iltuminate green.
- Use a mobile, laptop or desktop device to search for available WiFi networks. Connect to, ‘Cloud (product serial number)’ using the password, ‘password’. The amplifier serial number can be found on its rear panel.
- Open a mobile, laptop or desktop device web browser and enter the following IP address: 192.168.4.1. The amplifier configuration web interface page will open in the browser app to enable amplifier configuration as required.
It is strongly recommended that the CXA amplifier WiFi password is changed following initial wireless connection.
A laptop or desktop device with Ethernet functionality, a web browser and a
network scanning app is required.
Follow the steps below.
- Connect the CXA amplifier Network Control socket to a free socket on a network router or network switch using an Ethernet cable.
- Connect the CXA amplifier to mains power using the supplied mains cable and wait for the front panel Network indicator to illuminate green to indicate that the amplifier has been assigned an IP address.
- Use a network scanner app to identify the IP address assigned by the network router to the CXA amplifier.
- Open a laptop or desktop device web browser and enter the IP address identified in the Step 3 above. The amplifier configuration web interface page will open to enable amplifier configuration as required.
This symbol is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.
** CAUTION**

- Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
- To reduce the risk of electrical shock, the power cord shall be connected to a mains socket outlet with a protective earthing connection.
- Do not defeat the safety purpose of the polarized or grounding type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
