BASIC DSP™RECEIVERS
The LR LR-3200 is an Assistive Listening Receiver designed to be compact and simple to use. The unique
design of the receiver allows them to be worn as a necklace, using the belt clip or concealed in a pocket,
making this the most inconspicuous ALS receiver on the market.
Each receiver can be purchased with a Ear Phone/Neck Loop Lanyard that is designed to hold the receiver
like a necklace similar to the Blue Tooth™ transceivers used with many of the today’s hearing aids.
The Ear Phone/Neck Loop Lanyard can be used as the induction loop for those users who have T-coil
enabled hearing aids or cochlear implants, inducing the received audio directly into these T-coil enabled
devices. The Ear Phone/Neck Loop Lanyard also provides the connection to Listen’s Universal Ear Speaker,
Earphones and Headphones, incorporating a short connection cable that plugs directly into the Ear Phone/
Neck Loop Lanyards 3.5mm headset jack located 2/3 of the way up the lanyard. A second 3.5mm extension
cable provided with Listen’s universal earphones provides the length of cable required to place the receiver
in a pocket or using the belt clip.
