Product Description
The Contacta HLD2 1 to 1 loop driver is an under-counter audio amplifier for driving hearing induction loop systems, providing improved communication and customer experience for the hearing impaired.
*Please contact the CIE office on T 0115 9770075 for information on related products and accessories.
Combined with Contacta's IL-AE97 or IL-AE99 Loop Aerials and microphone options, this one-to-one hearing loop driver relays the sound source to someone wearing a hearing aid device. Contacta's HLD2 is very efficient with a high quality sound reproduction and controlled by a microprocessor which shuts off when not in use.
The HLD2 does not come with a power supply. You will require part codePS-55-00.
Also available in complete systems kits:
• IL-K200-00-00 Under Counter Induction Loop Kit with Mini Boundary Microphone
• IL-K200-00-00 Under Counter Induction Loop Kit with Mini Boundary Microphone
• IL-K200-20-00 Under Counter Induction Loop Kit with Halo Gooseneck Microphone
• IL-K300-00-00 Above Counter Induction Loop Kit with Mini Boundary Microphone
