Make every presentation, tour, or public event accessible with the Listen Technologies LS‑57‑072 iDSP Advanced Level II Stationary RF System. This professional assistive listening system from Listen Technologies is built for venues up to 100 people and delivers dependable, high‑fidelity audio so attendees never miss critical information. The kit pairs an LT‑800‑072 72 MHz transmitter with four LR‑5200‑072 iDSP receivers that offer multi‑channel selection for language interpretation and separate audio feeds.
