The Intelligent DSP IR Receiver Package 1 from Listen Technologies includes the LR-4200-IR iDSP IR Receiver, an integrated neck loop/lanyard, and a universal ear speaker.

Listen Technologies Intelligent DSP IR Receiver

The Listen Technologies Intelligent DSP IR Receiver is for use with the company's infrared assisted listening systems. The unit features two 3.5mm stereo output jacks that can drive two pairs of headphones or a single LA-430 lanyard for T-coil users (both available separately). The result is a convenient listening experience in small-to-medium places where it's difficult to hear—including theaters, boardrooms, classrooms, courtrooms, houses of worship, and more.

The receiver has an OLED display that shows unique channel names, battery status, channel status, volume status, and charge activation. The micro-USB connection is used with the free iDSP software suite for set up, programming, inventory management, firmware updates, and charging via any standard USB port. A field-replaceable, lithium-ion battery is included with the unit that powers it for up to 8 hours.

Listen Technologies LA-430 Intelligent Earphone Neck Loop Lanyard

The Listen Technologies LA-430 Intelligent Earphone Neck Loop Lanyard is an integrated neck loop that works with any of the company's iDSP receivers and any of their earphones (available separately) and uses a DSP loop driver to deliver an improved listening experience for people who have hearing aids and cochlear implants with telecoils. It is capable of providing the proper field strength and a flat frequency response from the neck to the listening plane of the hearing aid—in accordance with IEC60118-4 standards. An automatic gain control circuit with a dynamic range of 36 dB optimizes speech and provides clear, intelligible audio.

The LA-430 plugs into an iDSP receiver and easily slips over the head to be worn around the neck like a lanyard; a quick release ensures immediate removal if necessary. The 3.5mm earphone jack on one side provides a connection to Listen's universal earphones or a similar pair of earbuds. The LA-430 enables venues to meet legislative requirements for assistive listening and deliver an enjoyable listening experience in places where it's difficult to hear, such as theaters, lecture halls, concert venues, and houses of worship.
