- Audio I/O routing can be configured via the configuration web app.
- GPIO (General Purpose Input/Output) options can be configured via the configuration web app.
- Ensure that rack or other confined installation does not restrict the front to rear airflow required for safe and reliable operation of the amplifier. It is important that the 40°C maximum operating temperature for the amplifier 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 [Amp Name] amplifier to mains power using the supplied mains cable and switch it on via the front panel Standby switch. Wait for the front panel WiFi indicator to illuminate green.
- Use a mo bile, laptop or desktop device to search for available WiFi networks. Connect to, [Amp Name] (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.
