    Can I purchase additional LR-200-072 receivers for my LS-ADA-072 system?
    Yes! Order as many as needed. The additional receivers will need an earphone (LA-161) or any other Listen earphones and batteries before being used.
     
    What is the transmission range of the LS-ADA-072 system?
    Line of site up to 600 ft. (182.88 m) using the 90° Helical Antenna (72 MHz). Up to 1,500 ft. using other remote antenna options.
     
    Is there a limit to the number of transmitters I can use in one room?
    Yes. The 72 MHz LT-803-072 has a maximum of three.

    Yes. For best results, be sure the SQ function (Super Quiet) is turned off on any of the other receivers. Also, be sure to tune the receiver to the correct channel being used. All of Listen’s receivers (aside from the LR-200-072) can SEEK to find the best local 72-75 MHz transmission.

Also, the Signal to Noise is 62 dB compared to 80 dB on Listen’s other receivers.
