  • Mode 2 allows Dante audio via the Dante PoE Port, then TCP/IP and web-GUI control via the TCP/IP port

Dante® Audio
The NPA100DA features both a Dante Audio input and a Dante Audio output. The current source that is selected will always be the source that is output via Dante (eg: analogue line input, optical audio input, or HDMI ARC input). Please note: It is not possible to route the Dante® audio input into the NPA100DA to the Dante® audio output within the same NPA100DA due to limitations within the Dante® Ultimo chipset utilised.
Dante® Controller
Dante® Controller software is required in order to set up and configures the NPA100DA as well as control your Dante® network. Audinate provides extensive training videos and documentation on their website. This can be found here:

Upon connecting the NPA100DA to a compatible network, the Dante® Controller software should automatically discover the device. The NPA100DA will appear in the Dante® Controller with the name “NPA100DA”. On the “Routing” screen it is possible to then create audio routing between Dante® transmitters and receivers within the same system.

Dante® Controller
By default, the NPA100DA is shipped with the network settings set to obtain an IP Address automatically. This means that if a DHCP server is present on the network, the NPA100DA will be provided with an IP Address. If no DHCP server is present then the NPA100DA will receive a default IP Address in the range. To change the IP Address of the NPA100DA, enter the “Network Config” menu in the “Device Info” screen of the Dante® Controller software:

Advanced Dante® Settings

It is possible to change various Dante® related settings of the NPA100DA under the “Device Info” screen in the Dante® Controller software. To do so, select the “Device Config” menu.
Here it is possible to adjust the sample rate of the NPA100DA. Please note: that Dante® products can only transmit or receive audio from other Dante® products that are set up with the same sample rate. A mismatch in sample rate may stop audio from transmitting.
Under the “Device Config” screen the latency of the NPA100DA can be configured with a 1, 2 or 5 milliseconds delay.

Web-GUI Control

The NPA100DA features an in-built web GUI for the control and configuration of the unit. By default the device is set to DHCP, however if a DHCP server (eg: network router) is not installed the device IP address will revert to the below details:
Default Username: bloodstream
Default Password: 1234
Default IP Address:
The device can also be accessed via its mDNS name which is defaulted to: http://npa100da.local/
The web-GUI supports multiple users along with multiple user permissions as follows:
Guest Account – This account does not require a user to log in. The Guest account can only change sources for each zone. Guest access can be changed by the Admin, limiting inputs or outputs as necessary. The Guest account can be disabled.
User Accounts – User accounts can be utilised, each with individual login details. User accounts can be assigned permissions to specific areas and functions. A User must log in to make use of these functions.
Admin Account – This account allows full access to all functions of the unit as well as assigning users with permissions as required.
Login Page:
The Login Page allows a user or admin to log in and access additional functionality within the web GUI.
Once a user is selected from the list it is required to enter the password for that user in order to sign in
Please note the first time the Admin logs into the web GUI, the default admin password will need to be changed. It is important to record this password as there is no way to recover it in the event that it is forgotten.
Guest Control Page:
The Guest Control Page allows a guest to change source inputs by simply selecting the square that corresponds with the input you wish to listen to. The guest can also adjust the master volume output of the unit by using the volume slider or the volume up / down buttons as well as the mute toggle button.
The guest user also has the ability to adjust the microphone input volume, as well as select the MIC only button which will mute all source audio with the exception of the microphone input.

Input Page
: The Input Page allows for a user to adjust settings related to the inputs of the NPA100DA, including changing the source input. To change inputs, simply select the input required. The user also has the ability to adjust the volume for each input independently, as well as mute individual inputs. The following Microphone input settings can also be adjusted at the bottom of the Input page:

  • MIC Enabled – enable or disable the microphone input
  • Anti Feedback – when enabled, the unit attempts to reject microphone feedback loops to avoid squealing
  • Auto Gain – when enabled, the unit will automatically adjust the microphone input gain based on the audio signal level being received
  • Auto Duck – when enabled, the input audio signal will automatically reduce in level when microphone audio is sensed
  • Duck Level – when enabled, this is the level in % that the input audio signal will be reduced to
  • Duck Sensitivity – sets the sensitivity level of the Auto Duck function between 0-100 (low to high)
  • Mic GEQ – 3 band graphic EQ to adjust the audio performance of the microphone input

The user can also update their password via the Update Password button, or log out via the Log Out button.

Output Page:
The Output page allows users to change settings specific to the outputs of the NPA100DA. The NPA100DA features 4 audio output options:

  • Master output – this controls the audio output for all outputs (independent of the individual outputs below)
  • Amp output – this controls the audio amplifier output volume
  • Line output – this controls the analogue line-level output volume
  • Dante output – this controls the Dante audio output volume

It is also possible to invert either the left and/or right audio channel, mute each output, and mix each output (stereo output, left channel only, right channel only, left and right channels summed into mono) as well as adjust the audio delay from 0-50ms. The Amp output also has the ability to change the output impedance. It is important to configure this to either 4 or 8 to match the impedance of the speakers being used or you could risk clipping the amplifier output. A user can also adjust the 31 band GEQ (Graphic Equaliser) per each output channel (Amp, Line and Dante). There are 3 configuration options – Flat, Custom and Custom 2, where a user can save their own configuration into these slots.

User Page:
The Users page allows the admin to add, remove or disable users. Updating the passwords of a user can be carried out from here also.
You can adjust individual user permissions such as source input selection and output selection, to allow users access to only specific inputs and outputs.
Settings Page:
The Settings page allows users to change settings specific to the network configuration of the NPA100DA such as the devices IP address and port settings. You can also adjust the mDNS or Domain Name for the device, which can also be used to access the unit via, for example, http://NPA100DA.local/
