Specifications

Perimeter Loops – Area Coverage (maximum)

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.

Combined systems for very large areas

Multiple ILD1000G amplifiers can be combined using Ampetronic ILC Parallel DriveTM technology to drive systems in excess of 4000m2
Contact Ampetronic support for details.

Maximum Cable Length

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*
1.0mm2 copper 132 153
2.5mm2 copper 181 230
4.0mm2 copper 188 246
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.

INPUTS

Power 120W 230V AC nominal, 45-65Hz [120V option available]
Power switch and LED indicator on front panel
Input 1 XLR balanced microphone input for 200-600Ω microphones;
15dB user selectable gain boost; + 15V DC phantom power (selectable); sensitivity – 55dBu; front panel recessed gain control
Input 2 Selectable microphone / line XLR balanced input, switched between microphone and line on the rear panel. Microphone specifications as for input 1
Line specifications: 15dB user selectable gain boost;
sensitivity -30dBu; overload protected; phantom power disabled in line mode; front panel recessed gain control
Input 3 Line input 6.3mm jack socket balanced line input; sensitivity -30dBu;
overload protected, front panel recessed gain control
Link I/O 6.3mm jack socket insert point for connection of SP5 phase shifter
0dBu signal can be used for recording

OUTPUTS

Drive voltage 31.8Vrms 45V peak at maximum output current
Drive current • 9.2Arms (13Apk) continuous 1kHz sine wave peak >13A
• Short term peaks >19A
• Front panel recessed control
• Drive current indicated on 6-LED display in 3dB increments
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

 

AUDIO SYSTEM

Frequency response 80Hz to 6.5kHz
Distortion THD+N
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.

ADDITIONAL FUNCTIONS

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
Status Contact A pair of relay contacts are provided for remote fault monitoring
Ancillary To supply Ampetronic ancillary units ±15V DC 0.15A power outlet on rear panel
Cooling Forced ventilation. Air intake on left panel, air ejection at rear

 

PHYSICAL

Dimensions Full width 1U 19″ rack mount
Width 430mm Depth 220mm Height 44mm
Mounting options • Freestanding
• 1U 19″ rack mount (brackets included)
• Wall mounting (requires additional brackets)
Weight 3.75kg
Environment IP20 rated; 20 to 90% relative humidity; 0 to 35ºC
Standards

Standards compliance

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.
Some Ampetronic products are CSA registered for sale in the USA and Canada – contact Ampetronic for details.

ILD1000G Professional rack mountable loop driver

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.

Applications include

  • Conference facilities
  • Large places of worship
  • Theatres
  • Sports halls
  • Lecture halls
  • Cinemas
