9.2ARMS, for areas up to 1300m2
The ILD1000G sets the standard for high performance professional perimeter induction loop systems. Utilising a new amplification technology, the ILD1000G provides the highest power output available in a single channel amplifier, while halving power consumption and heat dissipation.
It features ample power to drive the largest perimeter loops to over 1300m2, and high voltage headroom to ensure high quality audio output even in the longest cable runs. All of this power and performance is packaged in an elegant and space efficient 19”1U case.
The ILD1000G is also designed for versatility, with 3 configurable inputs to cope with any scenario, usable freestanding, wall mounted or rack mounted with the included brackets. The ILD1000G is built to our exacting standards and is backed by our 5 year warranty.

Ampetronic can supply an extensive range of additional accessories for installation – discuss your requirements with our sales team and we will provide materials and equipment to suit your application.
|Input adaptors||A range of input adaptors and interface cables to accept most audio source inputs, see table below|
|Installation Accessories||• 18mm x 0.25mm copper tape
• PVC extrusion to protect copper tape
• Installation / warning tape to fix cable or tape to a floor
|Wall mount brackets||WMF1-U|
|Phase shifter||SP5 for an array system requires a design which can be provided by Ampetronic|
By using the appropriate input adaptor or preamplifier the ILD1000G will accept multiple additional inputs or audio inputs from other sources:
|Additional microphone||MP221 preamps can drive up to 2 mics + 2 line inputs|
|100V line input
Low impedance speaker line
|ATT-UJ & ATT-UX transformer isolated attenuators|
|Unbalanced microphones||MAT1 adaptor|
Capable of driving the largest practical perimeter loops – theoretical area coverage >1000m2 for square areas, >1300m2 for rectangular areas, though the practical limit may be set by the installation environment. Ampetronic design tools and support are available to check the expected performance for your application.
Multiple ILD1000G amplifiers can be combined using Ampetronic ILC Parallel DriveTM technology to drive systems in excess of 4000m2
Contact Ampetronic support for details.
The ILD1000G is designed for SINGLE TURN loops for optimum audio quality.
For loops with DC resistance from 0.5 to 3.0Ω , impedance to 3.5Ω
Maximum cable length is dependent on cable type and on the application:
|Cable type||Maximum Cable Length (m)|
|Normal Use*||Transient Speech*|
|1.8mm2 flat copper tape||233||271|
* Short term speech (e.g. service counter, airport PA system) can cope with limited clipping at high frequencies – Ampetronic recommends delivery of full current up to 1.2kHz for these applications.
Longer term usage or signals with music or high quality audio must deliver full current to at least 1.6kHz to prevent fatigue and give acceptable intelligibility. Many commercially available systems do not deliver sufficient voltage to reproduce critical high frequencies – ask us for more details.

|Loop connector||Neutrik NL4 Speakon (supplied)|
|Loop monitor||Provides access to actual loop current via a 3.5mm stereo
headphone connector on front panel
|Status||A pair of isolated relay contacts to indicate system status;
fault = open circuit: system O.K. = short circuit
|Idle||1/6 peak Output Current (Speech)||1/3 peak Output Current (Pink noise)||Full Power|
|Driver||Channels||Current (ARMS)||Load Resistance (Ohms)||AC In (W)||BTU||AC In (W)||BTU||AC In (W)||BTU||AC In (W)||BTU|
|Frequency response||80Hz to 6.5kHz|
|Automatic gain control||The AGC is optimised for speech. Dynamic range >36dB|
|Metal loss correction||Corrects system frequency response due to metal structures in a building.
Gain constant at 1kHz, adjustable gain slope from 0 to 3dB per octave. This does not compensate for signal loss from metal structures which can be significant.
|Fault monitoring||Three LED fault indicators on the front panel;
• Overload – delivering over the rated current or voltage
• Overheat – unit is too hot (mutes output signal)
• Loop error – short circuit / open circuit error

The ILD1000G is CE marked to all relevant safety and EMC standards.
All Ampetronic amplifiers can be used to create a system that meets the requirements of IEC118-4 and the relevant recommendation of BS7594, however the design and installation of the system is equally important to meet these Induction Loop Standards.
