Counter Loop Driver

Power supply (PS-55-01) sold separately.

Our innovative 1 to 1 Hearing Loop Driver is a special type of audio amplifier designed especially for driving hearing loops.

Applications

For use in any situation where one to one communication takes place at a counter, booth or desk, such as in: 

  • Banks
  • Post offices
  • Supermarkets
  • Theatres
  • Information centres
  • Airports
Standards
  • Induction loop performance compliant with BS EN60118-4 (when correctly installed)
Features
  • Microprocessor control
  • Energy-saving “green” standby mode is achieving a power saving of up to 80% during quiet periods
  • Advanced audio processing feature AGC, compression, and noise gate
  • Constant-current loop drive
  • Continuous self-testing
  • Isolated audio line input allows the driver to take alternative audio sources (optional)
  • Power and LED status indication
Specifications
Physical Data
  • Dimensions:
    Height - 116mm (4.57”)
    Width - 116.2mm (4.58”)
    Depth - 40mm (1.57”) 
  • Weight: 120g (0.26lbs)
  • Construction: ABS Plastic Construction Housing
  • Finish: Matt Black Fine Texture
Technical Data

Inputs
  • Input 1 (Microphone):
    Screw terminals on 3.8mm 2 pole Phoenix connector
    Single-ended electret microphone, powered by 5V via 2.2K ohms
  • Input 2 (Line) (Optional, HLD2-01 only):
    Screw terminals on 3.8mm 2 pole Phoenix connector
    Transformer isolated, 0dBu into 1K Ω, may have series resistance added for optional 75V or 100V line inputs
  • Power: Centre positive power jack, 14V DC 2.14A via 2.1mm from our power supply unit (PS-55)
Loop Output
  • Loop connection: Screw terminals on 3.8mm 2 pole Phoenix connector
  • Loop drive current: 2Arms compliance current @ 1kHz sine wave
  • Loop drive voltage: 4Vrms compliance voltage @ 1kHz sine wave
Audio
  • Frequency response: 100Hz – 5kHz (±3dB)
  • Distortion: Better than -40dB, inputs at nominal level
Automatic Gain Control
  • Processor controlled:
    Dynamic range: 40dB typical
  • Attack time: 10 milliseconds
  • Release time: typically 10 seconds, varies with program content
Indications
  • Status LEDs:
  • 3 colour LEDs indicate power, input and output diagnostic information
  • Connection provided for our LED halo indicator microphone
Self Test
  • Microprocessor controlled: Unit, including microphone and loop connections is continuously monitored, and internal and external LED indicators are updated
Energy Saving
  • Sound activated: Unit will enter low energy “sleep” mode when acoustic conditions indicate lack of usage
