Configuring the Nyquist Matrix Mixer
Pre-Amp
The Nyquist Matrix Mixer Pre-Amp (NQ-P0100) is a mixer preamplifier that allows micro-
phone, AES3 digital, and line-level source inputs to be integrated into a Nyquist system.
These input sources can then be routed to any endpoint or group of endpoints on the
network for paging or audio distribution.
You can let the Nyquist server automatically discover and configure the Matrix Mixer Pre-
Amp, or you can manually configure it through the Matrix Mixer Pre-Amp’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 automatic configuration process, refer to the 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 inter-
face.

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

this value will be auto-configured via DHCP option
66, assuming the DHCP server has been configured
to provide option 66. For details, see the documenta-
tion for your DHCP server.
Note: A TFTP server runs on the Nyquist server on
port 69 (the standard TFTP port) and the optional
Nyquist DHCP service automatically provides this
TFTP address via option 66.
Note: If this value is unspecified, the DHCP Server
Override will automatically be set to “Yes”, this field
will become read-only, and DHCP will be used to con-
figure this setting. To change this value, the DHCP
Server Override setting must be set to No, which
makes the field editable.
Note: This setting is not available when Standalone
Operation is enabled.
DHCP Server Override “Yes” means the device will use the DHCP option 66
value to retrieve an address for the TFTP Server from
DHCP.
“No” means the device will ignore the DHCP option
66 value and use the manually configured value of
the TFTP Server (see above).
Note: This setting is not available when Standalone
Operation is enabled.
