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 management and distribution capabilities of
Bogen’s Nyquist platform.
The NQ-GA20P2 appliance uses the latest in Class D amplifier tech-
nology and provides unparalleled sonic quality, exceptional reliability,
and reduced power consumption to permit standalone PoE+ opera-
tion over the local network.
You can let the Nyquist server or system controller automatically dis-
cover and configure the NG-GA20P2, or you can manually configure
it 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 the process for manual configuration.
For information about using Nyquist’s automatic configuration pro-
cess, refer to the appropriate Nyquist System Administrator Man-
ual.
Note: Do not use third-party Chrome browser extensions with the
Nyquist user interface.
