Accessories

ILD500 optional accessories

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

Input adaptors and preamplifiers

By using the appropriate input adaptor or preamplifier the ILD500 will accept multiple additional inputs or audio inputs from other sources:

Input type Adaptor
Additional microphone and / or line inputs 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

The ILD500 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.

Perimeter Loops – Area Coverage (maximum)

Room aspect ratio 1:1 2:1 3:1
Maximum area m2 420 525 700

 

For any Induction Loop System, area coverage is dependent on several factors. Please check these assumptions and contact Ampetronic for advice if required:

  • Loop must be 1-2m above or below the receiver height
  • There should be no metal structures in the plane of the loop
  • Sufficient voltage to drive the loop – check the cable table below

Maximum Cable Length

The ILD500 is designed for SINGLE TURN loops for optimum audio quality.

  • Loops with DC resistance from 0.3 to 2.0Ω
  • Impedance up to a maximum of 2.2Ω

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 83 96
2.5mm2 copper 114 145
4.0mm2 copper 118 154
1.8mm2 flat copper tape 147 170

 

* 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.

ILD500 Specifications

INPUTS

Power 85W 230V AC nominal, 45-65Hz [120V option available]
Power switch and LED indicator on front panel
Microphone input XLR balanced microphone input for 200-600Ω microphones;
15dB user selectable gain boost; + 15V DC phantom power (selectable); sensitivity – 70dBu; front panel recessed gain control
Line input 6.4mm jack socket balanced line input; sensitivity – 30dBu; overload protected; front panel recessed gain control
Link I/O 6.4mm jack insert point for connection of SP5 phase shifter
0dBu signal can be used for recording

OUTPUTS

Drive voltage 17.0 Vrms (24.0Vpk) at maximum output current
Drive current 6.4 Arms (9.0Apk) continuous 1kHz sine wave
Short term peaks: >13A
Front panel recessed control
Drive current indicated on 6-LED display in 2dB increments
Loop connector Neutrik NL4 (supplied)
Loop Monitor Provides access to actual audio signal in loop
3.5mm stereo headphone connector on front panel

Freq. response 80Hz to 6.5kHz
Distortion THD+N
Automatic Gain Control The AGC is optimised for speech. Dynamic range >36dB
Front panel recessed input level control
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
• Overheat – unit is too hot (mutes output signal)
• Loop error – short circuit / open circuit error
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
