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
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 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
- Frequency response: 100Hz – 5kHz (±3dB)
- Distortion: Better than -40dB, inputs at nominal level
- Processor controlled:
Dynamic range: 40dB typical - Attack time: 10 milliseconds
- Release time: typically 10 seconds, varies with program content
- Status LEDs:
- 3 colour LEDs indicate power, input and output diagnostic information
- Connection provided for our LED halo indicator microphone
- Microprocessor controlled: Unit, including microphone and loop connections is continuously monitored, and internal and external LED indicators are updated
- Sound activated: Unit will enter low energy “sleep” mode when acoustic conditions indicate lack of usage
