USING MULTIPLE EMITTERS

Listening areas of more than 10,000 square feet (930 square meters) will require a TX10 and

at least one TX8 Emitter for complete coverage. Place one TX10 transmitter on the left side

of the front wall and one TX8 emitter on the right hand side. For extremely large venue,

additional TX8s should be located to maximize coverage throughout the listening area.

Figures 5a and 5b illustrate infrared light patterns and recommended emitter locations. A

WIRM-1 Infrared Field Strength Meter may be used to check signal strength if the TX-10 is

operating on 95 kHz.

Step 1: Determine the length of coaxial cable needed to reach between the emitters. 100

feet (30 m) of coaxial cable is included with each emitter. You will need to cut it to

length. Additional RG–58 coax can be added. Make sure you leave some slack at

each end.

Step 2: Install BNC connectors on each end of the cable. (See Figure 13.)

Step 3: Connect the baseband cable from the Baseband Out jack on the TX10 Transmitter

to the Baseband In jack on the first TX8 emitter in the chain. Use the cable clamps

and screws provided to secure the cable. The coax can also be routed through

conduit before attaching BNC connectors. You can chain as many emitters together

as you need. Remember that each emitter needs its own power supply.
