Amplifier Output
The NPA70DA amplifier is capable of outputting the same
power at both 4 ohms and 8 ohms. The amplifier output
power varies depending on the input power supply or PoE
adapter connected to it, it does this by adjusting the internal
gain to allow you to get the most of the amplifier. Please
ensure that you select the correct impedence option via
the speaker impedence selection switch on the rear of the
device.

Trigger Connection
The NPA70DA features a trigger input to allow 3rd party devices to trigger the units power on or o.
When the trigger input senses a low voltage level (0V) it will enable the amplifier output, while when
it senses a high voltage level (5-12V) it will disable the amplifier out. This feature is enabeld by default
and can be adjusted via the web-GUI, or control API.
Network Connections
The NPA70DA features 2 x RJ45 sockets for combined or independent Dante® network and Control network
connectivity. The Network Mode switch, located next to the RJ45 socket, determines the mode of operation for the
RJ45 sockets as follows:
• Mode 1 allows combined Dante® audio, TCP/IP, and web-GUI control via the Dante® PoE++ port
• Mode 2 allows Dante® audio via the Dante® PoE Port, then TCP/IP and web-GUI control via the TCP/IP port

The NPA70DA features a Dante® Audio input as its only source input. The current source that is selected via Dante®
Controller will always be the source that is output via NPA70DA.
Dante® Controller soware is required in order to setup and configure the NPA70DA as well as control your Dante®
network. Audinate provide extensive training videos and documentation on their website. This can be found here:
http://www.audinate.com/products/soware/dante-controller
Upon connecting the NPA70DA to a compatible network, the Dante® Controller soware should automatically discover
the device. The NPA70DA will appear in the Dante® Controller with the name “NPA70DA”. On the “Routing” screen it is
possible to then create audio routing between Dante® transmitters and receivers within the same system.
Dante® Audio & Dante® Controller

NPA70DA USER MANUAL
www.blustream.com.au |www.blustream-us.com |www.blustream.co.uk08
Advanced Dante® Settings
It is possible to change various Dante® related settings of the NPA70DA under the “Device Info” screen in the Dante®
Controller soware. To do so, select the “Device Config” menu.
Here it is possible to adjust the sample rate of the NPA70DA. 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 NPA70DA can be configured with 1, 2 or 5 milliseconds delay.
By default, the NPA70DA 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 NPA70DA will be provided with an IP Address. If no DHCP server
is present then the NPA70DA will receive a default IP Address in the 169.254.xxx.xxx range. To change the IP Address
of the NPA70DA, enter the “Network Config” menu in the “Device Info” screen of the Dante® Controller soware:

Web-GUI Control
The NPA70DA features an in-built web-GUI for 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 below details:
Default Username: blustream Default Password: 1234 Default IP Address: 192.168.0.200
The device can also be accessed via its mDNS name which is defaulted to: http://NPA70DA.local/
The web-GUI supports multiple users along with multiple user permissions as follows:
Guest Account - This account does not require a user to login. 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 login and access additional functionality within the web GUI.
Once a user is selected from the list it is required to enter the pasword 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.

NPA70DA USER MANUAL
www.blustream.com.au |www.blustream-us.com |www.blustream.co.uk10
User Control Page:
The User Control Page allows a user to adjust the volume for the input our output, as well as mute the audio signal.
The input volume adjustment could act as an audio limit function to limit the maximum output volume. A User can
also adjust the signal mix (single channel only, stero or summed mono), audio delay or 31 band graphic eq with +3dB /
-10dB of adjustment.
The user can also update their password via the Update Password button, or log out via the Log Out button.
Guest Control Page:
The Guest Control Page allows a guest to adjust the master output volume of the unit by using the volume slider or the
volume up / down buttons as well as the mute toggle button.

User Page:
The Users page allows the admin to add, remove or disable users. Updating passwords of a user can be carried out
from here also.
Settings Page:
The Settings page allows users to change settings specific to the network configuration of the NPA70DA 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 unit via, for example: http://NPA70DA.local/

NPA70DA USER MANUAL

System Page:
The System page allows users to change the system configuration of the NPA70DA such as:
• Indentification - flashes the ID LED on front of the unit for the specified time period
• Key Lock On/O - enable or disable to front panel keys from functioning
• Power On/O - turn the unit on or o
• Input Trigger On/O - enable or disable input trigger function
• Power Mode - if the NPA70DA is connected to DC power supply, then PoE power modes will not be selectable. If
the NPA70DA is connected via PoE, it will default to the minimum PoE power specification (PoE+ Type 2 Class 4). It
is recommended to set this to the PoE power specification of the PoE adapter powering the NPA70DA
• Front Panel Lights - enable or disable the front panel LED lights, or set them to time out aer a specific time (15, 30
or 60 seconds)
• Serial Baud Rate - specify the baud rate of the serial RS-232 port on the device
• Auto Standby Time (minutes) - specify the time in minutes where the unit will enter standby mode if no audio
signal is being received on the selected input (default is 10 minutes)
• Firmware Update - allows a user to update the firmware of the device
• Factory Reset (Excludes Network Settings) - factory defaults all settings except for network configuration
• Factory Reset (Includes Network Settings) - factory defaults all settings including network configuration
• Reboot - power cycles the unit without changing any configuration settings
