Comtek CC-75 Overview
The Comtek CC-75 MLD Large Area Assistive Listening System includes a base station transmitter with rack mount, two receivers, two earphones, a remote dipole antenna, and a 12-volt power supply. The system can also be used with optional stereo or mono headphones, direct audio input cords with hearing aids, cochlear implant processors, and neckloops for hearing aids with a T coil. The CC-75 MLD is designed for use in scenarios where multiple transmitters are operating independently in the same building.
The base station transmitter is flash-memory programmable for quick setting recalls and is designed for permanent installation. The receivers are powered by two AA batteries for up to 100-hours and feature AutoSmart tuning that allows them to tune to the nearest compatible receiver. You can integrate additional PR-75 receivers into the system depending on your needs.
