Description

Ampetronic
ILD1000G Professional Rack Mountable Audio Induction Loop Driver   9.2Arms   for areas up to 1300m sq


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.

Features
  • Very high output for the largest applications
  • High efficiency class-G amplifier with low heat dissipation
  • Very compact 1U rack mount, wall mount or free standing

ILD1000G optional accessories

Ashton Audio 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

 

Input adaptors and preamplifiers

By using the appropriate input adaptor or preamplifier the ILD1000G will accept multiple additional inputs or audio inputs 
from other sources:

Input type

Adaptor

Additional microphone

MP221 preamps can drive up to 2 mics + 2 line inputs

100V line input
Low impedance speaker line
Line Level

ATT-UJ & ATT-UX transformer isolated attenuators

Unbalanced microphones

MAT1 adaptor

 

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.

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 Ashton Audio 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:

* 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.

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 monitorProvides access to actual loop current via a 3.5mm stereo 
headphone connector on front panel
StatusA 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 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 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

CoolingForced ventilation. Air intake on left panel, air ejection at rear
