Description:

The Language Interpretation System, model WIR SYS 4, is the ideal package for courtrooms that may be required to translate up to four languages simultaneously. Participants wear the RX22-4 body-pack style receiver to listen to the language of their choice. They can sit anywhere in a 11,000 ft

area and can adjust the volume to meet their comfort level. For the hard of hearing participant, the RX22-4 receiver can be used with a neckloop (included) to amplify the participant’s telecoil equipped hearing aid. SoundPlus infrared technology ensures privacy and security: the message of the proceeding will not travel outside the walls of the courtroom.

Each WIR SYS 4 package includes: two (2) TX9 emitters, two (2) MOD 232 modulators, four (4) RX22-4 receivers, four (4) HED 021 headphones, one (1) NKL 001 neckloop, and one (1) RPK 005 rack panel kit. The WIR SYS 4 meets and exceeds government ADA regulations for public hearing assistance, and is backed by a five-year warranty.*

To determine the best location for the emitter, it helps to think of the IR emitter as an invisible floodlight. You’ll want to aim it so the listeners are “flooded” with the infrared light. The emitter should also be positioned high enough so it won’t be blocked by people and other physical obstructions. See Figure 6 below. Mount the emitter at least 2 ft. (.61 m) above the audience. Position the emitter to face in a slightly downward angle, 20°, that will increase the “throw” of the infrared beam.

Fig. 5: 3-Dimension Foot Pattern

Fig. 6: Vertical Beam Spread

The TX9 floods the listening audience with a cone shape light pattern as shown here.

Minimum Receiver Range When Operating with a TX9 Emitter in Single Channel Mode

The path of the cone shape light leaves a pattern on the ground, or "foot print, " and indicates where the strongest receiver reception will occur.

The actual coverage area will vary depending on the sensitivity of the receiver being used. Refer to Figures 4 and 7 to determine how many emitters are required for 100% coverage of the listening area.
