WIR TX75 Two-Channel Infrared Transmitter

System Overview

The WIR TX75 two-channel infrared transmitter combines infrared modulator and emitter technology into a single mountable enclosure—which reduces operating costs, eliminates the need for rack space and eases set-up.

The WIR TX75 is ideal for high-quality audio programs such as music, theater and audio description. The WIR TX75 will accept any line level, balanced or unbalanced audio inputs. Infrared receivers detect the transmission and convert the light signals back

into audio signals. The 2.3/2.8 MHz (or 3.3/3.8 MHz for TX75b) operating frequencies minimize high-efficiency lighting interference.

Up to two slave emitters can be added for additional coverage. Power, baseband, and digital data are fed to the slave emitters via a single CAT-5e cable for each emitter. No additional cables are required.

No FCC license or radio approval is required with this equipment. It can be used anywhere in the world.

NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area may cause interference in which case the user will be required to correct the interference at his own expense.

NOTE: A PLASMA MONITOR OR TELEVISION CAN DEGRADE THE AUDIO QUALITY OF THE WIR TX75 TRANSMITTER. FOR BEST PERFORMANCE, THE TRANSMITTER SHOULD BE POSITIONED AS FAR AWAY AS POSSIBLE FROM ANY PLASMA MONITOR OR TELEVISION.
