1. INTRODUCTION

Congratulations on your purchase of a NT series network amplifier. The NT's flexible design will provide you with up to eight channels of audio with advanced DSP processing. A single NT amplifier offers eight-in, eight-out support (or four-in, four-out), and the entire system can be controlled through standard potentiometers or flexible remote software. Internal processing is accomplished through a high quality 40-bit floating point processor, with internal signal processors and routing all handled with ease.

NT series digital network amplifiers offer easy, effective means for injecting signal processors directly into your input and output path, with clear, easy-to-use software both onboard and on your Windows computer. The software offers full performance monitoring for each processor, giving real-time information on the load placed upon DSPs.

AUDIO OUTPUT

These euroblock outputs are used to connect speakers, either in low-impedance or distributed lines depending on your model. Amplified outputs are wired like so:

PIN 1: Cold (-)

PIN 2: Hot (+)

Each pair of amplified output channels can be bridged into one channel. This combines the output power of both channels creating a single channel with twice as much power.

To bridge channels, just wire the "+" pin of an odd-numbered channel to the "+" pin of the next even channel. When bridged, the "+" pin of the even channel becomes the "-" pin of the bridged new output.

When activating bridge mode, be sure to go into the Control Panel menu of the NT software and click the corresponding "Bridged" button.

4.4 IP ADDRESS SETUP

Connecting the NT series network amplifier to a computer for remote operation requires the user to enter an IP address for the unit. There are two controls that help determined the IP address of the NT network amplifiers. The first is the UNIT ID rotary control, that lets you select 0 – 9 and A – F. The second is the DIP switch located directly beside the rotary switch. The 3rd and 4th poles of the DIP switch can be used to set a numerical value between 0 and 3. These combine with the UNIT ID rotary switch to form a hexadecimal value for the last value of the IP address (as indicated below).

192.168.0.Xx 1 2 3 4 5 6 7 8

These values can be calculated in decimal using a programmer's calculator, or by checking the chart provided at the bottom of this page. The below image indicates how the last part of the IP address is determined using these switches

The DIP switch allows the first digit shown below to be selected between 0, 1, 2 and 3 with the configurations shown below. This determines the first digit of the IP address (in hexadecimal).

Value	3rd Pole	4th Pole
0	OFF	OFF
1	ON	OFF
2	OFF	ON
3	ON	ON

The UNIT ID rotary control allows a value between 0 and F to be selected. This determines the second digit of the IP address (in hexadecimal).

Once both digits of the hexadecimal IP address have been selected, it still needs to be converted to decimal for the user to have an accurate IP address. This is where the table below comes into play. If the DIP switches are set as "2" and Unit ID is F, this equals a hexadecimal value of 2F which converts to a decimal value of 47 (shown below). Therefore, in this example, the IP will be 192.168.0.47.

When setting the IP address using the UNIT ID controls, the second pole of the DIP switch must be set to the upper position. When in the lower position, the system will use the IP address set through the Windows Remote software.

1. Power on the NT series network amplifier.
2. Switch POLE 7 to OFF.
3. Switch the Power Switch to the "I" position (stand by).
4. Now your NT is restored to the factory default settings.

NOTE: A factory restore is particularly helpful in the event that user names and passwords are forgotten. Restoring to factory default settings will restore user names back to default values.

4.7 ACTIVATING ROTARY CONTROLS

Use pole 6 on the rear panel DIP switch to turn the front panel controls on and off. When OFF, the rotary volume controls on the front of the NT will be deactivated. In the event that controls are not functioning, be sure to check this before taking further action.

1 2 3 4 5 6 7 8

In addition to this switch, each and every individual control can be deactivated within the software. Within the Control Panel page, the ON/OFF buttons at the very bottom of each channel will allow you to turn the front panel rotary controls on and off.

4.8 FIRMWARE UPDATE

When performing a firmware update, a few steps need to be followed. First of all, set the first pole of the DIP switch to the upper-most position.

1 2 3 4 5 6 7 8

A connection needs to be established between the NT system and the Windows remote software. After this is done, enter the Global Settings tab and the Utility menu. At the very bottom of the page, click the "Update" button under the Firmware section. Users will be prompted to select the firmware file (available on the Asystems website) and the firmware update process will begin.

5. CONTROL SOFTWARE

Front Level Control: The Control Panel page also includes an on/off button for the front-panel level controls. These can be used in addition to the rear panel DIP (pole 6) to deactivate individual front panel rotary controls. In addition to this button, users can view the position of their front panel rotary controls through the virtual rotary controls featured at the bottom of the page.

Global Settings

LIM - Limiter/Compressor Settings

This menu allows compressors and limiters to be applied to channel outputs.

Limiter Threshold: This control determines the threshold for the limiter function. This means that no signal will surpass the selected threshold, being 'compressed' at a ratio of infinity:1.

Compressor Threshold: Use this control to set the threshold of the compressor function. Any signals that surpass the selected threshold will be compressed at the selected ratio.

Compressor Ratio: This control can be used to set the ratio for the compressor. The ratio is expressed as :

.

Compressor Attack: This control adjusts the attack time of the compressor, essentially determining the time taken for the compressor to kick in after it passes the selected threshold.

Compressor Release: The release control determines the time the NT will wait before disengaging the compressor when the signal bypasses the selected threshold.

System Clock

System Clock: This menu allows you to select a master clock source for digital devices. Selecting 44.1 or 48 kHz will set the NT as the master clock source and determine the sampling rate. Selecting AES/EBU, Network, or Word Clock will set these as the master clock. Whenever a new clock source is selected, the ENTER button must be pushed to confirm.

Power Settings: There are three power settings on the NT. The software power can be turned on and off, essentially enabling the NT to be turned on and off via the software – including event scheduling. The hardware power can be selected on and off, essentially allow the unit to be activated and deactivated using the hardwired switch on the front of the NT.

Utility

All of the DSP processes can have their settings saved for later use. While there are a number of factory presets available, users are always encouraged to find their own settings and save them for later use. The NT has onboard storage for a number of settings to be saved, or users can connect USB flash drives to save settings.

Also available in the Utility menu is a firmware update button. When a new version of firmware is available it can be installed using the "Update" button. Place the firmware update file on a formatted USB flash drive and insert it into a USB port. The "Update" button should take care of the rest.

After the firmware is updated, the initialize button can be selected to reset the device. Save any settings (or "scenes") before initializing the system.

Network

There are two pages under this tab.

PC

The PC menu offers a number of fields for network configuration. The user can offer a device name in this menu, while also including fields for the IP Address, Subnet Mask and Gateway Address.

The DHCP button allows users to enable a Dynamic Host Configuration Protocol on the unit. Enabling the DHCP allows your network to automatically provides an Internet Protocol (IP) host with its IP address and other related configuration information such as the subnet mask and default gateway.
