CC-75 Higher Power Large Area Assistive Listening System (FCC Part 90)

The CC-75 large area assistive listening system features the all new PR-75 AutoSmart-Tuning® receiver and BST-75 higher power base station transmitter operating under FCC Part 90 with 120 mW with remote dipole antenna. With a simple, one-button tuning control, the PR-75 receiver will automatically select the transmitter in closest proximity. This system is ideal where multiple transmitters in the 72-76 MHz band are operating independently in the same building. The PR-75 AutoSmart-Tuning® receiver makes it possible for the listener to use the same receiver to attend multiple programs at church services, school classes, museum exhibits, theaters, and stadiums, etc.

The BST-75 base station transmitter may be used with a rack mount and an external antenna for permanent installation or placed on a table top using the plug-in antenna on top of the transmitter for portable, easy system set up. The BST-75 transmitter is powered by 12 volt DC or AC power for permanent or field installations. The PR-75 receiver operates for 100 hours on two AA batteries and may be used with headphones, direct audio input cords for use with hearing aids, cochlear implant processors, and also with the NTC-102 neckloop for use with hearing aids having a "T" coil.

The complete CC-75 system includes one BST-75 synthesized base station transmitter, PR-75 AutoSmart-Tuning® receiver, SM-N earphone or LS-3 headset, RMK-75 rack mount, and RDA-2b remote dipole antenna.

Optional Accessory:


The NBC 9-3-12 Digital Fast Charger / Storage Case with self-diagnostic features will charge up to 12 PR-75 receivers and allows for easy system management. A full charge is obtained between 1/2 to 5 hrs. depending on battery charge status. LEDs provide an indication as to which batteries are fully charged and which ones are still being charged.
