Configuring the Nyquist Integrated

Power Amplifier

The NQ-GA20P2 is a plenum-rated Nyquist 20-watt integrated power amplifier that

works as a page zone extender to facilitate voice access to a single zone of one-way

paging over the Nyquist network.

It also works in background music applications, leveraging the exhaustive audio manage-

ment and distribution capabilities of Bogen’s Nyquist platform.

The NQ-GA20P2 appliance uses the latest in Class D amplifier technology and provides

unparalleled sonic quality, exceptional reliability, and reduced power consumption to

permit standalone PoE+ operation over the local network.

The Nyquist server or system controller can automatically discover and configure the NQ-

GA20P2, but you can also manage the device, and manually configure some settings,

through the appliance’s web-based user interface (web UI).

A short 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 settings and configurations that can be applied to this device

which are not controlled by the Nyquist server. For information about using Nyquist’s auto-

matic configuration process, refer to the appropriate Nyquist System Administrator Guide.

To access the appliance’s UI:

1Access 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 web UI navigation bar, select Stations, select Stations Status,

navigate to the device that you want to configure, and then select the Link icon.

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

2At the Nyquist Appliance Login page, enter username and password, and then select

The dashboard for the selected appliance appears.

Using the Dashboard

The dashboard displays the following fields:

Figure 1. Nyquist Appliance Login

Figure 2. NQ-GA20P2 Dashboard

The following buttons are available at the top of all pages in the application.

Table 1. Appliance Dashboard Fields

Device Type Identifies the model of this device.

Serial Number Identifies the serial number for the device.

MAC Address Specifies the Media Access Control (MAC) address,

which is a unique identifier assigned to network inter-

faces for communications on the physical network seg-

ment.

Firmware Version Provides the firmware version installed on the device.

Standalone Operation Enables or disables Standalone mode.

Table 2. Appliance Dashboard Buttons

Dashboard Displays the dashboard.

Configuration Settings Accesses the Configuration Settings page where you can

view and set various options. If Standalone Operation is

not enabled, you can also receive configuration settings

from a Nyquist server.

Network Settings Accesses the Network Settings page where you can view

and set network settings, such as the static IP address.

Firmware Update Accesses the Firmware Update page where you can view

the current Nyquist version, update firmware to a new

version, restore the configuration to factory defaults,

and reboot the appliance.

Logs Accesses log files, which record either events or mes-

sages that occur when software runs and are used when

troubleshooting the appliance.

DSP Accesses the DSP page where you can view and set

parameters for Digital Signal Processing (DSP).

Help Accesses the appliance’s online help.

Manual Displays this appliance’s configuration guide.

Logout Logs out of the appliance’s dashboard.

Standalone Operation

This device can run in Standalone Operation mode, where it will not interact with a

Nyquist server (e.g., E7000 or C4000). This means the device will not:

• Fetch device configuration from Nyquist server

• Register with Nyquist server (via SIP)

• Store backup information to Nyquist server

• Allow access to Nyquist server-based NTP

Standalone Operation mode is ideal for scenarios that do not require the full functionality

provided by an integrated system, such as the Bogen C4000 or E7000 Series, but has the

ability to provide paging, multi-channel audio processing, and a SIP endpoint for a PBX/

VoIP phone system. It can be used to play music, audio, paging, and related functions.

Updating Firmware

When you select Firmware Update from the appliance’s web UI, the Firmware Update

page appears. From this page you can determine which Nyquist firmware version the

appliance is using and if an update is available. You can also load a firmware release,

install the loaded firmware, restore the configuration to factory defaults, and reboot the

appliance.

Note: A Nyquist appliance connected to the Nyquist network receives a configuration

file from the Nyquist server that includes the latest firmware available from the server.

If the firmware is different from the one installed on the appliance, an automatic firm-

ware update occurs unless the Firmware parameter for the station is left blank. Refer to

the Nyquist System Administrator Guide for more information.

To use the Firmware Update page:

1On the appliance web UI’s main page, select Firmware Update to view or update the

firmware version.

2If the device is in Standalone mode, selecting the Check for Updates button checks

the Bogen website for the latest firmware version available. If a version newer than

the one currently installed is found, it is downloaded to the appliance.

3If you already have a firmware file you would like to install to the appliance, select

Upload Firmware to upload the firmware file from your computer to the appliance. A

popup screen appears that allows you to select the file that you want to upload. You

can navigate to the file’s location. After you select the file, select Upload.

4The page displays the uploaded firmware version (“New Nyquist Version”) and an

Update Firmware button appears. Select this button if you want to update the appli-

ance’s firmware to the uploaded version.

5If you want to return your appliance to its original factory configuration, select

Restore Factory Settings.

6Select Reboot Appliance to restart your appliance.

Figure 3. Firmware Update Page

Network Settings Tab Parameters

Network settings can be configured dynamically by the Nyquist server or manually by

using the appliance’s web UI.

To manually configure network settings:

1On the appliance web UI’s main page, select Network Settings.

Table 3. Firmware Update settings

Current Nyquist Version Shows the version of the appliance’s currently

installed firmware.

New Nyquist Version Shows the version of the firmware that has been

loaded, though not installed, onto the appliance.

Update Firmware Available only when a new firmware version has

been loaded onto the appliance (as specified in

New Nyquist Version).

Installs the loaded firmware. A reboot may be

required after installation.

Upload Firmware Prompts the user to specify a firmware file, which

will then be loaded (though not installed) onto the

appliance.

Note: To obtain the firmware file for a specific ver-

sion, please contact Bogen Customer Service.

Check for Updates Available only when the appliance is configured

for Standalone mode.

Checks the Bogen website for the latest firmware

version available and, if it finds a version newer

than what is currently installed, downloads it to

the appliance.

Restore Factory Settings Returns the appliance to its original factory con-

figuration.

Note: This does not install the original appliance

firmware. The firmware will not be changed.

Reboot Appliance Restarts the appliance.
