MODULATOR SET-UP • Position the MOD 232 Modulator near the sound system or mixer from which it will receive audio. • Connect the power supply to the 3-pin Molex connector located in the back of the MOD 232. A green LED will illuminate on the front of the MOD 232 when the power switch is in the “On” position.
Configuration Switches
• Audio connection: The MOD 232 Modulator will accept a microphone using 3-pin male connector, or a 1/4 phone plug with a balanced or unbalanced line level signal. Connect the sound system accordingly to the audio inputs in the back of the MOD 232 labeled “Input CHA” and “Input CHB.”
Made in USA
• The MOD 232 Modulator has four selectable frequencies to choose from: 2.3, 2.8, 3.3, 3.8 MHz. This system is pre-set to 2.3 and 2.8 MHz. Frequency selection can be adjusted by using the “Configuration Switches” located on the back of the MOD 232 (see page 4). • Prepare MOD 232 to be connected to the TX9 emitter. Determine the length of RG-58 cable needed to reach from the emitter to the Modulator unit. Install BNC connectors to each end of the cable (see page 23 in manual). © 2010, Williams Sound

TX9 EMITTER SET-UP • Determine the coverage area needed for the seating area. When using the RX22-4 receiver, one TX9 will cover an area of 28,000 sq. ft. (2,600 sq. m.) in single channel mode. In two-channel mode, one TX9 will cover an area of approximately 18,000 sq. ft. (1,700 sq. m.). In four-channel mode, the coverage area is approx. 11,000 sq. ft. (1,000 sq. m.). Coverage area will vary depending on the sensitivity of the infrared receiver being used. See coverage drawings on pages 12-15 in the manual. To determine how many TX9 emitters are required for 100% coverage of the listening area, we recommend performing a site test.

• Determine placement and location for the TX9. Ideally, the emitter should be located high enough so not to interfere with people or other obstructions. Mount the emitter at least 2 ft. (.61 m) above the audience. The TX9 may need to be angled slightly downward to maximize the coverage area. Wall and ceiling mount brackets are available for permanent installation of the TX9 (see pages 16-17 in the manual). Emitter stands are available for portable applications (see pages 18-20 in the manual). • Connect the power supply to the 3-pin Molex connector located in the back of the TX9. When power is supplied to the TX9 emitter, a green LED indicator will be visible underneath the unit. When the baseband is activated, a red LED indicator will be visible underneath the unit. • Connect the baseband cable to the “Baseband Out” jack in the rear of the MOD 232, then connect the cable to the “Baseband Input” jack in the rear of the TX9 emitter. Additional TX9 emitters can be linked together as needed for coverage. See illustration in Figure A.
RX22-4 RECEIVER SET-UP • The RX22-4 comes standard with 2 AA alkaline batteries. • Plug in an earphone or headphone in the jack on top of the unit. • Rotate the receiver on/off/volume switch to turn the receiver on. A red “on” indicator will illuminate on top of the unit. Adjust the volume control to a comfortable listening level. • Turn the channel selector knob on the top of the unit to select from 2.3 MHz (Ch. 1), 2.8 MHz (Ch. 2), 3.3 MHz (Ch. 3), or 3.8 MHz (Ch. 4). • The RX22-4 can be tested by holding it up to the infrared emitter labeled “IR” on the front of the MOD 232 Modulator.

Above: Typical 4-channel configuration when using (2) MOD 232 Modulator, TX9 Emitter, and optional RX22-4 Receiver.
Note: Make sure the “SoundPlus IR” artwork is facing the TX9 emitter (Figure B). The front of the RX22-4 should not be covered; do not place the receiver in pants or shirt pocket. Do not obstruct the light path between the RX22-4 Receiver and the TX9 emitter or the unit will not function properly.
See manual for additional receiver instructions.
The four-channel set-up is similar to the described two-channel set-up (pages 1-2). The difference is the installation of an additional MOD 232 Modulator: RX22-4 FRONT
• Use the WCA 068 short coaxial cable (Figure C above) to link the two MOD 232 Modulators. • Connect the short coaxial cable to the “Baseband Output” jack of the first MOD 232 in the chain. Connect the other end of the short coaxial cable to the “Baseband Input” jack of the second MOD 232 in the chain.
QUICK SET-UP TROUBLE-SHOOTING
• Each modulator is set-up to accept two audio inputs. When the modulators are linked, they can accept a total of four audio inputs. Connect the input signals to the audio inputs in the back of the MOD 232 labeled “Input CHA” and “Input CHB.” Frequencies are pre-set to 2.3, 2.8, 3.3, 3.8 MHz. Frequency selection can be adjusted by using the “Configuration Switches” located on the back of the MOD 232 (see page 4).
• Is the sound system on and audio source active? • Are the power cables for the Emitter and Modulator secured and plugged in? • Are the power switches for the Modulator and Receiver in the “On” position?
• Wiring the Modulator to the TX9 Emitter: Connect a coaxial cable to the “Baseband Output” jack of the second MOD 232 in the chain. The other end of the coaxial cable will connect to the “Baseband Input” jack of the TX9. Additional TX9 Emitters can be linked together as needed for coverage. See Figure C above.
• Are the “On” LED indicators visible on the Emitter, Modulator and Receiver? • Are the baseband cables connected to the correct input/output jack? • Is the baseband LED “On” indicator illuminated underneath the Emitter? • Are the correct frequencies selected on the Modulator? • Are there obstructions between the Emitter signal and the Receiver? • Are the batteries in the Receiver installed and working?
