ILD1000G Professional rack mountable loop driver

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.

  • 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 typeMaximum Cable Length (m)
    Normal Use*Transient Speech*
    1.0mm2 copper132153
    2.5mm2 copper181230
    4.0mm2 copper188246
    1.8mm2 flat copper tape233271

     

    * 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.

    AUDIO SYSTEM

    Frequency response80Hz to 6.5kHz
    DistortionTHD+N
    Automatic gain controlThe AGC is optimised for speech. Dynamic range >36dB
    Metal loss correctionCorrects 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 monitoringThree 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 ContactA pair of relay contacts are provided for remote fault monitoring
    AncillaryTo supply Ampetronic ancillary units ±15V DC 0.15A power outlet on rear panel
    CoolingForced ventilation. Air intake on left panel, air ejection at rear

  • 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.
