SYSTEM OVERVIEW

Thank you for purchasing the Personal PA Value Pack System from Williams Sound Corporation.

The PPA VP System is a Wide-Band FM Listening System which operates in the 72-76 MHz

frequency band. Designed for hearing assistance in places of public access, the PPA VP is for

those who need help overcoming background noise, reverberation, or distance from the sound

source. The versatile PPA VP is easily integrated with your existing sound system or can be used

with a microphone as a stand-alone system.

The system has two principal parts: the T17 Transmitter and the R35 Receiver. Much like a

miniature radio station, the Transmitter and microphone pick up the sounds you want to hear and

broadcast them over an FM radio signal. The receivers are used to pick up the broadcast up to

500 feet away.

To avoid difficulties, please read through these instructions as you begin to use the system. Then

save the manual for questions that arise as you continue to use your PERSONAL PA Value Pack

System.

If you have any problems with this Williams Sound product, don’t hesitate to call us toll-free at

1-800-843-3544.

T17 TRANSMITTER SET-UP AND INSTALLATION

STEP 1: INSTALL THE ANTENNA

The “rubber duckie” whip antenna fits into the hole on top of the transmitter and threads onto a

mounting stud inside. Guide the antenna onto the stud and turn it clockwise to tighten. Do not use

excessive force to tighten the antenna. It only needs to be “finger-tight.”

STEP 2: CONNECT THE TRANSMITTER TO POWER

The T17 is supplied with a wall transformer power supply. Plug the transformer into a 120 V, 60

Hz wall outlet. Then plug the power cord into the “Power” connector on the rear panel of the T17.

The green indicator light on the front panel of the T17 should glow when the power is connected.

There is no on/off switch. The T17 is designed to be continuously on. The wall transformer can

be plugged into a switched outlet that turns on when the other sound equipment is turned on. If

turning the T17 on creates a hum or buzz in the sound system, see the Troubleshooting section on

page 16.

STEP 3: MAKE AUDIO CONNECTIONS

3A: (IF YOU WILL BE USING THE T17 WITH ITS OWN MICROPHONE AS A STAND-ALONE SYSTEM)

Any Williams Sound microphone with a 3.5 mm mini phone plug can be used with the T17.

Plug the microphone into the “Mic” jack on the front panel of the T17.

The T17 is designed to supply positive DC voltage to the plug tip of 2-wire, “barefoot”

electret (power condenser) microphones. If you will be using the T17 with a non-Williams

Sound, Lo-Z (dynamic) microphone, this DC power should be turned off. (See page 7.) If you

use both the Microphone input and the Audio Input on the T17, the signals will be mixed

together.

3B: (IF YOU WILL BE USING THE T17 WITH AN EXISTING SOUND SYSTEM)

Refer to the figure 1 on page 3. Use the audio cable supplied to connect the T17 “Audio In”

jack to an appropriate audio output jack on the sound system mixer or amplifier. The T17 is

designed to work with an unbalanced, line-level audio signal. Suitable connections are:

Choice 1: TAPE OUT or LINE OUT Jack

Choice 2: BOOSTER or BRIDGING Jack

Choice 3: Speaker Terminal, 8 Ohm Tap

If your amplifier or mixer does not have RCA-type connectors, you can obtain adapters from

your Williams Sound Authorized Dealer or a local radio parts store. If the TAPE OUT jack is

already in use, a Y-Cord can be used to connect the T17 and a second device to the same jack.

STEP 4: TEST THE SYSTEM

Use a receiver to test the system and set the input level control. See the section, Receiver Use

Instructions.

TURNING OFF DC MICROPHONE POWER

The T17 is designed to supply positive DC voltage to the plug tip of 2-wire, “barefoot” electret

(power condenser) microphones. If you will be using the T17 with a non-Williams Sound, Lo-Z

(dynamic) microphone, this DC power should be turned off. (See Figure 4.) If you use both the

Microphone input and the Audio Input on the T17, the signals will be mixed together.

Step 1: Unplug the power cord from the T17 and remove its antenna.

Step 2: Use a phillips-type screwdriver to loosen the two screws on the rear of the

Transmitter. Remove the cover. Slide the circuit board out of the case.

Step 3: Use the diagram to locate the HD4 Jumper. This black jumper is also labeled on the

T17 circuit board.

Step 4: Pull the HD4 Jumper off the two pins it connects. DO NOT MAKE ANY OTHER

ADJUSTMENTS! For handy storage, simply turn the jumper sideways and place it

on just one of the two pins.

Step 5: Re-assemble the Transmitter.

FREQUENCY CHANGE INSTRUCTIONS

Normally, the PPA VP’s factory-set channel (usually 72.9 MHz) requires no change. However, if

another hearing assistance system or authorized radio service is operating on 72.9 MHz in your

area, it may prove necessary to use an alternate channel In this event, the PPA VP’s operating

frequency can easily be changed to an alternate channel to avoid interference.

TRANSMITTER FREQUENCY CHANGE INSTRUCTIONS:

IMPORTANT: Some cities have other radio services licensed on hearing assistance channels.

Under FCC rules governing hearing assistance, you must yield to them. A list of cities where

other radio services are known to exist is included with the transmitter. Do not use frequencies

that are known to be used by licensed radio services in your city, either if they are on the list or if

you discover one.

Step 1: Unplug the power cord from the Transmitter and remove the antenna.

Step 2: Use a phillips-type screwdriver to loosen the two screws on the rear of the

Transmitter. Remove the cover. Slide the circuit board out of the case.

Step 3: Use the diagram to locate the frequency selector switches on the circuit board.

Locate the switch programming chart on the bottom of the Transmitter case.

FIGURE 6: SETTING THE T17 FREQUENCY SELECTOR SWITCHES

12345678

OFF

Switches set for 72.9 MHz

IMPORTANT: Make sure the FM receiver being used is operating on the same frequency

as the T17 transmitter. See R35 frequency change instructions on page 12.

Step 4: Use a paper clip or small screwdriver (not a pencil point) to move the switches to

correspond with the switch positions on the programming chart. (See Figure 6.)

Select a new frequency at least two channels away from the one you are

experiencing interference on. DO NOT TOUCH ANY OF THE OTHER

ADJUSTMENTS!

Step 5: Re-assemble the Transmitter and plug it in. Connect a tape player or radio to the

transmitter to provide a tuning signal for the receivers.

CAUTION!
