Configuring the Nyquist 4-Channel Audio Power Amplifiers

Bogen’s Nyquist-based networked four-channel audio power amplifiers (NQ-A4060-G2, NQ-A4120-G2, NQ-A4300-G2) support small, medium, and large Nyquist intercom solutions in schools and in commercial paging and public address solutions.

Available in 240-, 480-, and 1200-watt models, the audio power amplifiers provide flexibility and versatility without the need for add-on modules. Each model offers state-of-the-art, built-in Digital Signal Processing (DSP) software—including factory loudspeaker presets—that turns the amplifier into a complete audio solution.

A two-second press of the appliance’s Reset button reboots the device. If you press the Reset button for 10 seconds, the appliance returns to the factory default configuration settings. Returning to the default configuration settings does not change the appliance’s firmware.

The following sections describe the process for manual configuration. For information about using Nyquist’s automatic configuration process, refer to the appropriate Nyquist System Administrator Guide.

Note: Do not use third-party Chrome browser extensions with the Nyquist user interface.

To access the appliance’s Web-based user interface (UI):

1Before accessing the web UI for the first time, the Bogen Certification Authority (CA) digital certificate must be installed on the client. This certificate can be downloaded from any Nyquist appliance and enables your browser to recognize the Nyquist web application as a trusted site.

For details on how to download and install the certificate to your client computers, see "Installing the Bogen Digital Certification Authority".

2Access the appliance’s web UI by doing one of the following:

a)On your web browser, enter the IP address for the appliance as the URL.

b)From the Nyquist server’s web UI navigation bar, select Stations, select Stations Status or Appliance Status, navigate to the device that you want to configure, and then select the Link icon.
