Easier access to cultural services – Sennheiser presents new infrared receivers

They use invisible light to work behind the scenes in many public facilities: infrared systems transmit information and music in museums and churches, amplify the sound in theatres for those with a hearing impairment and enable people to enjoy television at their own individual volume without disturbing others. With the new HDI 830 infrared stethoset receiver and RI 830 S bodypack receiver for use with headphones or hearing aid accessories, audio specialist Sennheiser is now offering two new stereo/two-channel models.
 

The two new receivers can be used wherever broadband infrared technology provides clearly intelligible sound in a high quality. They are compatible with Sennheiser’s SI 30, SI 1015 and SZI 1015-T infrared modulators and feature outstanding audio quality. Their frequency response extends from 50 to 16,000 Hz, also making them the ideal choice for listening to music. Both receivers can be switched between the A and B mono channels (2.3 and 2.8 MHz carrier frequencies) or used for stereo listening.   “Assistive listening is becoming increasingly important worldwide,” explained Martin Gurtner, Industry Team Manager for Installed Sound at Sennheiser. “The pioneers are above all the Anglo-Saxon countries, who take their obligation to provide accessible, “barrier-free” cultural services very seriously. In other countries too, there is an increasing awareness among cultural service providers, with theatres and churches now offering their visitors this flexible and high-quality form of assistive listening. Our new receivers are aimed at cultural facilities looking for a sturdy, low-cost and high-quality audio transmission solution.” Convenience for the user Their top-quality, ergonomic design makes the two receivers both attractive and user-friendly at the same time. The large volume control and balance adjuster allow the sound to be individually adapted for optimum listening.   The HDI 830 stethoset receiver comes with its own headphones. Perfectly fitting, adjustable ear cushions and a low weight ensure optimum wearing comfort. The receiver switches on automatically as soon as the ear bows are opened – and switches off again when they are closed.   The RI 830 S receiver is ideally suited for use with headphones or with hearing aid accessories such as induction neckloops or induction couplers, which are connected to the 3.5 mm jack plug socket. The on/off switch is integrated into the centre of the easy-to-use volume control.

Environmentally friendly charging technology
The charging unit takes just three hours to charge the receivers and their BA 300 accupack for up to 12 hours of use. The L 300 10-10 charging unit is designed in such a way that receivers can be placed in the unit in any direction. The charging process starts automatically, and the state of charge is displayed via LEDs. The charging unit has space for a total of ten receivers and a further ten single accupacks. A special assembly kit for desktop mounting is available as an accessory.
 
The HDI 830 and RI 830 S infrared receivers and the matching L 300 10-10 charging unit will be available in stores from October.
