2. Introduction
This D Series Induction loop driver range have been designed as high quality digital, networkable
singleanddualloopoutputdrivers,primarilyforusewithmultipleloop(MultiLoop)orPhasedArray
loop designs or where the facility to control or access the unit via a network is required.
An Array System provides a solution where a simple loop around the room perimeter will not work.
Arrays are the standard solution for buildings with metal structure or reinforcements, or for covering
large areas. Arrays can also dramatically decrease the ‘spill’ of the magnetic signal outside of the
room, allowing induction loops to be installed in adjacent rooms, and providing an improved level
ofcondentiality.Arrayscanalsobeusedtochangethewaytwoloopsinterferewitheachother,
providing ways of solving even the most complex installation problems.
Depending on a number of factors regarding the installation of the loop and the set-up of the driver
the D Series drivers can provide compliance with IEC60118-4 for perimeter loop areas of up to 2 x
1,300m2 or phased array systems upto 3,300m2.
Ease of installation, set-up and operation have been major factors in the design, combined with
optimised performance, and the freedom from R.F.I. generation.
TheDSeriesoutputchannelscanbeconguredtobeshiftedinphaseby90°,orinphasewith

Induction Loops’ handbook available from the Ampetronic website or contact Ampetronic for advice.
Location
The unit may be free standing or 19” rack mountable using the rack ‘ears’ supplied. Fitting of the
‘ears’ is achieved by removing the three forward most screws on both sides. The same screws

Operation
If you are unfamiliar with Ampetronic D Series products please pay close attention to the setup
procedure in order to take advantage of the advanced features that these drivers offer.
The D Series drivers analyse the loops that they are connected to at switch-on to check that
theyhavetherequiredcharacteristics.Iftheloopresistanceexceeds10ΩthentheerrorLEDwill
illuminate and a warning about high loop resistance is displayed. If the loop output clips whilst the
500Hz test tone is active a warning about the loop being open circuit is displayed.
The driver has two inputs labelled 1 and 2. Both inputs can be set to line, mic or mic with phantom
power.Additionallyinput2hasanAESdigitalinputaccessedthroughthesameXLRsocket.The
driver has two loop outputs labelled Loop A and Loop B. enabled versions of the drivers
are also available.
Factory Settings
From the factory the drivers are provided with the following setting:
Current: -20dB from full output
Metal Loss Compensation (MLC) OFF
Input Gain Channel 1 -80.0
Input Gain Channel 2 -80.0
Driver Name “Name not set”
Phase Shift OFF
DC 12V Power OFF
Ethernet Parameters Set by DHCP
MLC OFF
TheDSeriesdrivershavetheiradjustmentsetindecibels(dB).Asettingof0dBequatesto
maximum current or to maximum input gain. A value of less than 0dB will reduce the current
or input gain accordingly. This change is to simplify adjusting the driver output to meet the
international performance Standard.
If the loop output is measured to be 2.7dB below the required level then adding 2.7dB to the current
output should bring it to the Standard.

connecting a wireless router to the driver for WiFi access.
Control Interfaces
The D Series drivers have two user control interfaces.
1. Capacitive Touch interface on the unit front panel
2. Browser Interface available via a network connection
(username: admin, password: ampetronic)
The front panel touch switches and LCD display implement a simple menu system on the front of
the driver whilst the Ethernet interface allows control through a web browser on a remote device.
The driver web interface can be accessed by connecting an Ethernet cable from a computer
EthernetporttotheD-SeriesEthernetport.Openabrowser(Chromeisrecommended)andenter
the following numbers into the address bar: 169.254.0.10
Ampetronic D Series Installation Handbook & User Guide Page 7
Start Up Tests
When D Series drivers are switched on they execute a series of tests that check the driver’s internal
systems and also the loops that they are connected to. These tests take about 5 seconds and the
display reads “DIAGNOSTICS IN PROGRESS” whilst they are being performed.
IfeverythingisOKthedisplayshouldread“AMPETRONICDXX-X”(wheretheX’schange
dependentuponthemodelofDSeriesdriveryouhavepurchased)onthetoplineandthenameof
thedriverunderneath.Ifanerrorwasdetectedthentherederrorlightwillashandthedisplaywill
read the cause of the error. Please refer to section 10 where the error messages are explained in
detail.
Initial Setting up
D Series drivers include a test signal generator that can produce 5 different test signals: Sinewave,
pinknoise,pinknoise–1Ksinewave(combi1K)signal,combi1.6kHzandcombi2.5kHz.
These signals over-ride the inputs on the back of the driver. Switching off the test signals routes the
sum of the signals on inputs 1 and 2 to the loop outputs.
N.B. This driver is not stereo in that input 1 does not exclusively drive loop A and input 2 drive loop
B. The factory default settings of the driver have both input gains set to -80dB which is effectively
off.

Setting up the Ethernet Interface
Ethernet infrastructure with DHCP server is available
ThefactorydefaultsettingfortheDynamicHostCongurationProtocol(DHCP)isenabled.This
allows the driver to request values for IP address, Gateway, Subnet Mask, Primary and Secondary
DNS values from the host network DHCP server.
If an existing Ethernet IP system is available then the driver can be plugged into it and it will
congureitself.WhenthedriverobtainsanIPaddressitwilldisplayitonthefrontpanelLCDfor5
seconds.
To view the web interface type the IP address displayed into the web browser address bar on your
device.
Ethernet infrastructure but DHCP is not available
If a DHCP server is not available, it is possible to enter values for the IP address, Subnet mask
DNS and Gateway from the front panel using menu 7 Ethernet. Before you can do this, you will
need to switch off DHCP and restart the driver.
After entering these values, the driver needs to be restarted again either by switching the power off
and on or selecting menu option 7.9 Sys Restart.
Caution: Setting the Ethernet values incorrectly can lead to problems on the Ethernet system and
could potentially bring the network down.

from the front panel or via another web connection, these changes will be shown on the web page
as they happen.
Settings Tab
The settings tab allows control of the most important settings of the driver. The items on this page
are sliders and drop down boxes. In order that the slider settings cannot be changed by a large
amount accidentally, the clicking on a slider track to set a value is disabled.
To alter a value it is necessary to click on the slider handle and move it. The value is not sent to the

possible to click in the text box next to the slider and enter a value directly. There are two important
points to note about directly entering values into the text box.
First, although the slider will move as the value is altered, no information is sent to the driver as this
happens.
Second, the value only gets sent to the driver when the edited slider “loses focus” which means that
youhavetoclick(ortouchifonamobiledevice)atapointsomewhereawayfromtheslideryou
have just adjusted. Only at this point is the new value transferred to the driver.
There are 13 adjustable parameters on the settings page:
Test Signal Freq: Controls the frequency of the continuous sine wave test signal
Test Signal: Drop down box that selects the test signal from OFF, Pink Noise,
Sine Wave, Combi 1K, Combi 1.6K and Combi 2.5K
Current: Controls the level of current to loops A and B. Maximum current is
with the slider at 0 dB and minimum with the slider at -80 dB
Current Offset: Controls the level of current B with reference to current A. A

11. AUDIO NETWORKING
Dante network audio enabled D Series drivers contain all the necessary hardware to connect simply
to a Dante controlled network.
To connect your D Series driver to a Dante controlled network you will need to connect the driver to
a networked switch via the Dante network port on the rear of the unit.
N.B. If the Dante network port is not installed then Dante is not supported on the unit.
To connect to a Dante network:
Turn on the driver and it should automatically be detected by the network and appear on the Dante
Controller software Router Tab
An example factory default Dante name for will appear as: AmpetronicD14-2-001EC0F91557
Where the ‘001EC0F91557’ part of the factory name is the MAC address of the control Ethernet
port on the D14-2 driver and this number can also be read from the web control interface.
Thus if you can get DANTE controller and a web browser running on the same PC, you can easily
match which driver is which on the DANTE controller.
If you are installing multiple D Series drivers on the same network it is possible to then change
the name to something more appropriate, e.g. D14-LectureTheatre3, in the ‘Device Info’ tab of the
Dante controller.
The Dante controller software is available on the Audinate website:
https://www.audinate.com/products/software/dante-controller
Full instructions and training on how to use the Dante controller, including the following topics and
troubleshooting tips for setting up a network are available on the Audinate Website:

12. Telnet Commands
Introduction
This document describes the telnet command format and the commands that the Driver recognises.
The Telnet interface of the Driver is on port 9760. Therefore to make a Telnet connection to an
amplierwhoseIPaddressis10.2.0.144theTelnetcommandwouldbe‘Telnet10.2.0.1449760’.
Command Format
The commands break down into two groups – those that set a value in the Driver and those that
read a value back.
Setting Commands
Thecommandisastringfollowedby“=”andthenthevalueasspeciedinthetablebelow.
For example, to set the current to -20dB the command is “cur=-20 ” is sent. The space command
(ASCIIcharacter32)isusedtoendacommandandtriggertheinterpretertoprocessthecommand.
This means that space is never used within a command.
The recognised commands are:
Command Function Accepted parameters
cur Sets the current drive level of the Driver -80 to 0
curo Sets the current offset. –ve means channel B is
quieter than channel A and visa versa -10 to +10
inp1 Set the input 1 gain dB -80 to 0
inp2 Set the input 2 gain dB -80 to 0
mlc1 SettherstMLCslopelevelindB/Octave 0.0 to 4.0
mlcf Set the MLC mid frequency in Hz 200 to 5000
mlc2 Set the second MLC slope level in dB/Octave 0.0 to 4.0
mlcq Use a pre-set MLC response 0 to 18
tfrq Set the frequency of the test sine wave in Hz 200 to 5000
tsts Setthetestsignalusedbytheamplier

”Pink”
“Sine”
in1m Set the input mode of channel 1 – send a number
corresponding to the required input mode
0 = “line”
1 = “mic no phantom”
2 = “mic with phantom”
in2m Set the input mode of channel 1 – send a number
corresponding to the required input mode
0 = “line”
1 = “mic no phantom”
2 = “mic with phantom”
3 = “AES digital input”
4=“DANTE”(iftted)
phse Sets the phase shift mode 0 = “no phase shift”
1 = “channel B shifted by 90”
pwlc Controls Emails on power cycling “true” enables,
“false” disables
erlc Controls Emails on error conditions “true” enables
“false” disables
