1. SoundPlus Infrared System Model WIR TX900 eoooc2Socscc Description The WIR TX900 is a high performance cost effective infrared system designed for simultaneous lan guage interpretation of up to four languages Operating on 2 3 3 8 MHz the WIR TX900 is less sus ceptible to traditional radio and lighting interference When using the optional RX22 4 four chan nel receiver the WIR TX900 will operate up to 28 000 ft in single channel mode ideal for auditori ums theaters or other large venues Applications e Simultaneous Interpretation e Audio Description Conferences Multi Media Rooms Boardrooms e Courtrooms Schools Universities e Cinema Churches MOD 232 Modulator Size Weight 8 5 Wx8 2 D x 1 7 H 21 5 cm x 20 8 cm x 4 4 cm 3 1 lbs 1 5 kg Color Black epoxy paint with white legends Rack Mount 1 2 rack space wide 1 rack space high one or two modulators may be mounted in a single IEC rack space with RPK 005 single or RPK 006 double Rack Mount Kits Power Supply Wall Transformer 24 VAC 50 60 Hz 15 VA North America TFP 016 UL CSA Europe TFP 027 01 2 pin Schuko plug CE UK TFP 027 02 3 pin UK plug CE Modulation FM Wideband 50kHz deviation 50uS pre emphasis Carrier Frequency Channel A Selectable 2 3 2 8 3 3 3 8 MHz Channel B Selectable 2 3 2 8 3 3 3 8 MHz Signal to Noise Ratio More than 60 dB Frequency Response 30 to 16 000 Hz 1 dB 3 dB electri2. Helping People Hear SoundPlus Infrared System Model WIR TX900 2000000609 Fig 5 3 Dimension Foot 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 flood light 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 6 Vertical Beam Spread Minimum Receiver Range When Operating with a TX9 Emitter in Single Channel Mode RX22 4 Receiver 150 45 m GL e RX14 2 80 24 m RX16 70 21 m E Range SCREEN STAGE NOTE SPECIFICATION
