4 Product Overview Components Our HLD9 is a pioneering modular hearing loop driver for perimeter or phased array congurations, suitable for large area applications such as theatres, conference facilities, sports arenas, concert halls and auditoria. The HLD9 uses cutting edge switching converter technology to deliver high eicacy and high performance with low noise. 1 2 3 4 5 1
Contacta HLD9, 5 1. Power Supply Input. Power Sources - This product should be operated only from the type of power source indicated on the marking label. If you are not sure of the type of power supply to your home, consult your product dealer or local power company.

Contacta HLD9, 14 Troubleshooting Symptom Possible Fault Action I’ve adjusted the HF comp and see no change. 1) The driver is working close to maximum output so there is not enough headroom for the HF comp to make a dierence. 1) Check loop characteristics. If response OK at 1 amp, the headroom is inadequate. I start the driver and immediately the status light turns on. I start the driver and test sequence starts, but after it’s done, the status light turns on. I’ve connected the loop and the driver doesn’t work, the status light comes on. My driver has been working well for a couple weeks and now
Contacta HLD9, 15 Symptom Possible Fault Action No signal on the line input. 1) No input signal connected. 2) HLD in slave mode. 3) Equipment failure. 1) Check “active” light: if unlit check source, if lit, adjust level. 2) HLD must be in PERIMETER or PRIMARY. 3) Seek assistance. The low signal light is on. 1) The HLD is having to use very high gain to process the input signal. 1) Increase the input signal level at source, reduce the HLD input level setting. The Drive level indicate current is owing but I hear nothing in the loop. 1) Shorted feeder cable (unlikely). 2) Loop listener not working or being used away from loop. 1) Check feeder cable,
