Williams Sound WIR SYS 75P PRO overview

  • 1Description

The WIR SYS 75P PRO Infrared Jury Deliberation Room System by Williams Sound is a two-channel professional infrared transmitter combining an infrared modulator and an emitter into a single mountable enclosure. It can be used for applications in various environments for high-quality audio programs such as music, theater and audio description. The WIR SYS 75P transmitter will accept any line level with balanced or unbalanced audio inputs. Infrared receivers detect the transmission and convert the light signals back into audio signals. The WIR SYS 75P operates on frequencies of 2.3 to 3.8MHz and minimizes high-efficiency lighting interference. LED status indicators can be turned off after the initial setup. No FCC license or radio approval is required with this equipment.
