Suitable for theaters, cinemas, auditoriums, classrooms, houses of worship, and more, the AL-9000 Assistive Listening Package from Anchor Audio provides a wireless listening-enhancement system for the hard-of-hearing, or indeed, anyone who wants to hear the goings on of a single-focused event more clearly.
Included in this package are four battery-powered belt-pack receivers, four in-ear headphones, a wireless transmitter base station, and a carrying case. Use the base station to connect dual inputs from the in-house system—or plug in microphones via its XLR inputs—and then transmit the signal to the listener wirelessly. The base station operates within a frequency range of 902 to 928 MHz, and each battery-powered belt-pack features 100 individual UHF channels for selecting between open frequencies.
Though this unit comes with four belt-pack receivers, it's completely expandable, so you can keep transmitting to people so long as the receiver can tune to your frequency. The AL-9000 is ADA compliant and rack mountable.
