Configuring the Four-Channel

Audio Power Amplifiers

Bogen’s Nyquist-based networked four-channel audio power ampli-

fiers (NQ-A4060, NQ-A4120, NQ-A4300) 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 ampli-

fiers 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 that includes factory loudspeaker presets

and that turns the amplifier into a complete audio solution.
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 the process for manual configuration.

For information about using Nyquist’s automatic configuration pro-

cess, refer to the

Nyquist System Administrator Manual

To access the appliance’s UI:

Step 1

Access the appliance’s web UI by doing one of the fol-
lowing:

a On your web browser, enter the IP address for the

appliance as the URL.

b From the Nyquist web UI navigation bar, select

Sta-

tions

, 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.
