FAQ

Q Can Listen's other 72 MHz receivers (LR-500-072, LR-400-072, and LR-300-072) be used with the LS-ADA-072 system?
A 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.

The LR-200-072 does not have an LCD screen, the ability to SEEK for open frequencies, SQ (Super Quiet), squelch or programmability. Also, the Signal to Noise is 62 dB compared to 80 dB on Listen’s other receivers.
Q Is there a limit to the number of transmitters I can use in one room?
A Yes. The 72 MHz LT-800-072 has a maximum of (8) eight.

The building came an exceptional, state-of-the-art sound system, equipped with assistive-listening units from Listen Technologies. We have been thrilled with the crisp, clear sound these units affords, as well as their ease of use.
