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
Perimeter Loops – Area Coverage (maximum)
Room aspect ratio 1:1 2:1 3:1
Maximum area m2 420 525 700

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
  • Slave 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

AUDIO SYSTEM

  • Frequency 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
