TX925 WIR Model • System Infrared®SoundPlus

SoundPlus® Infrared System •Model WIR TX925

D

Description:

The WIR TX925 is ideal for simultaneous language interpretation for up to two languages. It can operate up to 18,000 sq ft in two channel mode or 28,000 in single channel mode. Operating on 2.3 and 2.8 MHz, the WIR TX925 is less susceptible to traditional radio and lighting interference. Listen to the program with the optional RX22-4four-channelreceiver,RX14-2two-channelreceiver or the RX16two-channel/stereoreceiver.

Applications:

Simultaneous Interpretation • Audio Description • Media Rooms • Conferences • Boardrooms • Courtrooms

Schools • Universities • Cinemas • Churches

The coverage area for the TX9 will vary depending on the receiver being used. The diagram above demonstrates the receiver coverage when operating a single TX9 emitter in single channel mode. Patterns are direct radiation patterns.

Note: Reflections of the infrared light from walls, ceilings and floors may change these patterns.

Fig. 5: 3-DimensionFoot Pattern

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

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.

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.

Reflections of the infrared light from walls, ceilings, and floors may change these patterns. Important: Remember to point the emitter towards the listening audience!

If you’re not getting sufficient coverage with a single, properly installed TX9 Emitter, you may need to add additional WIR TX9 Emitters to achieve full coverage of your listening area. Figures 8a and 8b illustrate how multiple emitters can be used for large room installations.

Fig. 8a above is a typical example of how multiple emitters are used to cover larger listening areas. Generally it is desirable for the illumination patterns to overlap. Note: The coverage area will vary depending on the infrared receiver being used; refer to Figures 4 and 7 to determine how many emitters are required to achieve full coverage of a listening area.

Added to Same Emission Point (50% increase)

When two emitters are used at the same emission point in single channel mode, the overall coverage area increses 50%. When using an RX22-4receiver, as a result, the coverage area will increase to an estimated 42,000 ft2 (3,902 m2); theRX14-2will increase to 5,250 ft2 (488 m2); the RX16 will increase to 4,590 ft2 (426 m2 ).

Bid Specs

Modulator, Model MOD 232

The infrared system shall consist of separate modulator and emitter units, with portable receivers. The modulator unit shall be a half-rackstyle, metal enclosure. A rack panel shall be available to mount one or two modulator units within a single EIA rack space. An adjustable floor stand and mounting bracket shall be available to mount the modulator and emitter together for portable operation.

The modulator shall provide two channels of selectable FM carrier signals; 2.3/2.8/3.3/3.8 MHz, so that a single modulator can be used to simultaneously transmit up to two channels, and two modulators can be ganged together to transmit up to four channels simultaneously. The carrier signals shall use 50 kHz deviation and 50 µS pre-emphasis.The carrier signals (baseband) shall be transmitted to one or more emitters by 50 ohm RG58 coaxial cable withBNC-typeconnectors. ABNC–typebaseband input jack and baseband output jack shall be provided on the modulator. The modulator shall be powered by an external 24 VAC, 10 VA,50-60Hz power supply, connected via athree-pinMolex power connector.

It shall have a rocker-typepower switch, power LED indicator, four carrier indicator LEDs and two bargraph-typeLED audio indicators. The modulator shall have a modulated IR LED on the front panel for testing purposes, and a headphone jack that accommodates mono and stereo 1/4" headphones, and channel monitoring switch. The modulator shall have two rotary audio input level controls, and a screwdriver adjustable control for varying the input compression from 1:1 to 4:1. The modulator shall have two timers that automatically shut off the carriers when there is no audio signal present for 15 minutes. The modulator shall have two combination input jacks that accept3-pinXLR plugs for balanced microphone input or 1/4" TRS plugs for balanced or unbalancedline-levelinputs. The XLR inputs shall be low impedance, accept signal levels from 100 µV to 90 mV and supply 15 V simplex power per DIN45596. The TRS jacks shall accept balanced or unbalanced audio signal levels from 21 mV to 10 V. The modulator shall have CE, FCC, RoHS, and WEEE approval and carry afive-yearparts and labor warranty.

The modulator shall be the Williams Sound Corp. model MOD 232.

Emitter, Model TX9

The emitter shall be contained in a metal enclosure with a shatter-resistantlens. The emitter shall include anomni-direc-tional mounting bracket for permanent installation and a bracket shall be available for mounting on a floor stand for portable installations. Each emitter shall be powered by a 24 VAC, 50 VA,50-60Hz power supply. The power connector shall be a3-pinMolex-type.The emitter shall have aBNC-type50 ohm baseband input and aBNC-typebaseband 50 ohm output jack. The emitter shall have a repeater circuit to allow multiple numbers of emitters to operate from the baseband signal. The emitter shall have a visible LED indicator for power and for baseband signal. Carrier frequency is 50KHz to 8 MHz. The emitter shall shut off when the baseband signal is not present. The emitter shall provide an effective coverage area of 28,000 sq ft (2,600 sq m) in single channel mode and 18,000 sq ft (1,700 sq m) in two channel mode when using theRX22-4receiver. The emitter shall beconvection-cooled,without fans. The emitter shall have CE, FCC, RoHS, and WEEE approval and carry afive-yearwarranty on parts and labor.

The emitter shall be Williams Sound Corp. model WIR TX9.

Four-ChannelReceiver, ModelRX22-4

The receiver shall be a body-packtype with IR detector lens behind face of the unit. The unit shall have a lanyard for handsfree operation. The receiver shall have arotary-typevolume control. The receiver shall operate for 60 hours with two AA alkaline batteries and for 30 hours per charge with NiMH AA batteries. The receiver shall be charged without battery removal via charger contacts in the case. Adrop-incharger accessory shall recharge the batteries in 8 hours when used with CHG 3512 charger. The receiver shall be housed in an impact resistant plastic case with a hinged battery door that does not separate from the receiver. The receiver shall receive 2.3 MHz, 2.8 MHz, 3.3 MHz or 3.8 MHz modulated IR signals with 50 µSde-emphasis.The receiver shall have a 3.5 mm stereo phone jack and accommodatelow-impedancemono or stereo earphones and headphones. The receiver shall accommodate neckloop telecoil couplers. The receivers shall provide 110 dB SSPL90 output with EAR 013earbud-typeearphone.

The system electrical frequency response shall be 25 Hz to 16 kHz, +1, -3dB and thesignal-to-noiseratio shall be 60 dB. The receiver shall have CE, FCC, RoHS, and WEEE approval. The receiver shall be covered by afive-yearparts and labor warranty, excluding earphones, headphones, batteries and chargers.

The receiver shall be the Williams Sound Corp. model WIR RX22-4.
