+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.

+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?
