Configuring the Nyquist VoIP Speakers
The Nyquist VoIP Ceiling Speaker Gen 2 (NQ-S1810CT-G2) and Nyquist VoIP Wall Baffle
Speaker Gen 2 (NQ-S1811WT-G2) are VoIP talkback speakers designed to work with the
Nyquist Series IP network-based intercom and paging solution.
The ceiling talkback speaker assembly consists of an 8" cone speaker and VoIP module
preassembled onto a 13" steel ceiling grille painted with bright white enamel.
The VoIP wall baffle talkback speaker assembly consists of an 8" cone speaker and VoIP
module preassembled onto a bright white injection-molded wall baffle speaker enclo-
sure.
Both types of speakers are 802.3af-compliant and are designed to facilitate rapid and effi-
cient deployment using existing network Power over Ethernet (PoE) ports. They also have
a Form-C relay for controlling third-party devices. These VoIP speakers enable ease of
placement wherever needed within a facility.
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 firm-
ware.)
The Nyquist server can automatically discover and configure the Nyquist VoIP speakers,
but you can also manage the device and manually configure some settings through the
web-based user interface (web UI). The following sections describe the process for
manual configuration. For information about using Nyquist’s automatic configuration
process, refer to the Nyquist System Administrator Guide.
To access the appliance’s UI:

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 TFTP Server
from DHCP will automatically be set to “Yes”, this
field will become read-only, and DHCP will be used to
configure this setting. To change this value, the TFTP
Server from DHCP setting must be set to No, which
makes the field editable.
Note: This setting is not available when Standalone
Operation is enabled.
TFTP Server from DHCP “Yes” means the device will use the DHCP option 66
value to retrieve an address for the TFTP Server from

Setting DSP Parameters
When you select DSP from the appliance’s web UI, the DSP page appears.
From this page, you can set parameters for DSP, which is a form of processing that uses
digital data to simulate characteristics found in analog circuits. With DSP, you can alter
analog signals, such as audio signals, that have been converted to a digital format.
You can also select Save Settings to Server to back up all configuration settings to the
Nyquist server.
The DSP page allows you to adjust the signal level for the Output channel, as well as view-
ing level indicators for both the input and output signals. Selecting the DSP Features
button (hamburger menu above the OUT signal indicator) displays a menu that allows
you to access DSP features, as described in the following table.
Figure 7. DSP Page

16
Setting the Channel Level
The Channel Level control is a vertical slider that is adjusted in 1-dB increments and con-
trols the output level for the channel. The Channel Levels can range from -60 to 12 dB. If
you place the mouse over the slider, the numerical value of the level appears.
Adjusting Volume Levels
The vertical slider control can be used to adjust the channel’s output level in 1-dB incre-
ments between -60 and +12 dB. The overall adjusted output level of the channel signal
can be viewed on the OUT VU meter, marked in 2-dB increments between -60 and 0 dB.
Tip: For best results, use the vertical slider to adjust the input level until you have a strong signal (i.e.,
within the green and yellow areas on the meter), then adjust the final output levels using the DSP Outputs
controls.
To adjust the channel volume level:
1On the appliance Web UI’s main page, select DSP.
2Use the channel’s slider to adjust the volume level.
Knob Adjustments
Many DSP controls use knobs to adjust one or more settings. The value of a knob can be
adjusted in one of two ways:
1Click the knob control, hold the mouse button down, and drag the mouse up or down
to increase or decrease the value.
2Double-click the knob, type a value into the resulting popup, and click the Save but-
ton.

Presets
There are a number of DSP effects that are used to enhance the quality of the audio
signal being played on the VoIP speaker device (though not all of these effects are visible
and available for customization). Due to design differences between the VoIP speaker
models (e.g., microphone placement), these DSP settings must be customized for each
model.
Bogen has created predefined sets of model-specific DSP configurations to customize the
signal for each device. These configurations are available via Presets.
Note: It is important that the preset corresponding to the speaker model be specified.
Selecting Presets from the Menu icon on the DSP page displays the Presets page.
Table 8. Intercom Tuning Settings
Switching Sensitivity Specifies the minimum level of the received signal at which
the microphone signal will be muted and the output (i.e.,
speaker) channel will be enabled.
The range is -90 to -20 dB.
Talkback Threshold Specifies the minimum talkback (i.e., microphone) signal at
which talkback will be enabled. The lower the level, the
more sensitive the microphone is to activating.
The range is -144 to +24 dB.
Talkback Decay Specifies the rate (in dB/second) at which the noise gate
that enables the talkback (i.e., microphone) signal will close
once opened. A larger value means the gate will closer
faster, thus disabling the microphone signal sooner.
Tip: If the microphone audio sounds choppy, set this to a smaller
value.
The range is 0 to +1000 dB/sec.
