Channel Audio

Configuring the Two-Channel

Audio Power Amplifiers

Bogen’s Nyqust-based networked two-channel audio power amplifi-

ers (NQ-A2060, NQ-A2120, NQ-A2300) support small, medium, and

large Nyquist intercom solutions in schools and in commercial

paging and public address solutions.
Available in 120, 240 and 600-watt models, the audio power amplifi-

ers 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

lowing:

appliance as the URL.

tions
