Introduction

Our NPA70DA networked audio zone amplifier delivers advanced audio integration within a commercial or residential AV installation. The NPA70DA features a 2 x 35W digital amplifier (1 x 70W mono) or 70V / 100V hi-level constant voltage output and Dante® audio integration. The NPA70DA can be powered via PoE++ from a compatible network switch, or locally should the switch not support PoE++. The unit also includes the ability to lower the amplifier power output subject to PoE capabilities, support for combined or independent LAN and Dante® connections, DSP with a 31 band EQ, audio delay for lip sync correction, and control via front panel, IR, RS-232, TCP/IP, web-GUI or 12V trigger.

FEATURES

• Advanced network audio amplifier with Dante® integration
• Supports 2 x 35W @ 4 / 8 ohm, 1 x 70W @ 4 / 8 ohm or 70 / 100V constant output for multiple speakers with longer cable runs
• Supports power via PoE++ on Dante® LAN connection or local power supply*
• Dual network option – independent Dante® and LAN control ports, or combined to a single LAN
• 2ch Dante® / AES67 audio input
• DSP with 31 band EQ with +3dB/-10dB and audio delay
• Local 12V input trigger for automated power control
• Control via front panel, IR, RS-232 and IP
• Auto standby mode with signal sensing
• In-built web-GUI for setup and control

Trigger Connection

The NPA70DA features a trigger input to allow 3rd party devices to trigger the units power on or off. 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.

IR Connection
The NPA70DA supports both 5V and 12V IR receivers via the IR input. There is a toggle switch to the right of the IR input port to specify the voltage required. Please note: if using a Blustream IR receiver, the switch should be in the 5V position.

The wiring for a Blustream IR receiver is as follows:

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

Dante® Audio & Dante® Controller
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 software is required in order to setup and configure the NPA70DA as well as control your Dante® network. Audi provide extensive training videos and documentation on their website. This can be found here: http://www.audinate.com/products/software /dante-controller

Upon connecting the NPA70DA to a compatible network, the Dante® Controller software 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.within the web GUI.

Dante® Controller
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 software:

Advanced Dante® Settings

It is possible to change various Dante® related settings of the NPA70DA 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 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.

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 the 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.

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 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.

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/

System Page:
The System page allows users to change the system configuration of the NPA70DA such as:

• Identification: flashes the ID LED on front of the unit for the specified time period
• Key Lock On/Off: enable or disable to front panel keys from functioning
• Power On/Off:  turn the unit on or off
• Input Trigger On/Off: 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 after 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

Information Page:
The Information page provides useful information such as firmware version and network settings.
