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.

If you’re using the PPA VP with an existing sound system, make sure the sound system is turned on.
Have someone speak into a sound system microphone while you listen with the receiver and
earphone. You should be able to hear their voice through the receiver.
If you’re using the PPA VP with a microphone—and not a complete sound system—have someone
speak into the microphone while you listen with the receiver and earphone. You should be able to
hear their voice through the receiver.
R35 RECEIVER FREQUENCY CHANGE INSTRUCTIONS
Selecting a frequency for the R35 receiver requires an adjustment to the internal tuning
coil. See figure below to locate the coil to be adjusted. A plastic tuning wrench (PLT 005)
will be needed to adjust this receiver’s tuning coil.
Most Williams Sound single channel Receivers are set at the factory to 72.9 MHz.
The Receiver must be tuned with a weak and somewhat noisy signal. If tuned too close to
the transmitter, with a strong signal, the most accurate tuning of the receiver is not possible.
To Change the Frequency to Another Channel:
STEP 1: Set the transmitter to the channel desired and remove the antenna.
STEP 2: Connect an audio source to the transmitter such as a CD or cassette player or
microphone.
STEP 3: Move the receiver about 25 feet away from the transmitter to set the tuning.
STEP 4: Open the battery compartment on the back of the receiver.

STEP 5: Locate the Tuning Coil (see figure above). The tuning coil is a small. shiny
metal can with a screwdriver slot in a tuning slug in the top center. The Tuning Slug is
usually black or gray.
STEP 6: With the earphone or headphone supplied with the receiver plugged into the Ear Jack,
turn the volume control to a comfortable level, and listen for the transmitted signal.
STEP 7: Gently put the tip of the tuning wrench into the slot in the tuning slug. Be careful not to
push hard on the slug so as not to damage the threads in the coil, and do not screw it
down more than 3 turns into the coil.
STEP 8: Turn the tuning slug in a counterclockwise direction about two turns. Then, slowly turn
the tuning slug in the clockwise direction until the signal is heard. There may be two
signal points heard. The one which is received first is a false response. Be sure to
continue tuning slightly further to the correct point, which will be much louder. Tune
back and forth to find the center of the point of best response to the program being
heard.
STEP 9: Mark down the date, and if a new frequency has been chosen, mark it down inside the
receiver case for future reference.

USING A RECEIVER WITH A HEARING AID
Williams Sound PPA Receivers can be used with hearing aids using three different methods:
NECKLOOP TELECOIL COUPLER
Neckloops are cords which hang around the neck and couple magnetically with T-Coil equipped
hearing aids.
SILHOUETTE TELECOIL COUPLER
These telecoil couplers are worn behind the ear, right next to telecoil-equipped hearing aids.
DIRECT AUDIO INPUT (DAI) CORD
Direct Audio Input cords can be used with compatible hearing aids as well as with Cochlear
Implant Processors.
SUGGESTIONS FOR RECEIVER MANAGEMENT
Different types of facilities will use different approaches for receiver management and earphone
sanitation. Below are some options that customers have used successfully.
Regular users purchase their own receiver and take care of their own batteries and earphone.
Some facilities label the receiver and earphone with the names of regular users so each
person uses the same receiver and earphone.
Ushers issue receivers to people who request them. Earphones are sanitized after use. Foam
ear cushions can be replaced or washed with a mild detergent, rinsed thoroughly and air-
dried. The EAR 022 Surround Earphone can be sanitized with an alcohol pad.
The receivers can be stored in a multiple compartment storage case with a credit card or
driver's license left as collateral for the receiver.
Regular users purchase their own earphone or headphone and bring them to use with
receivers at the facility.

TROUBLE SHOOTING GUIDE
Read through the manual and user guide carefully to verify proper setup and installation of your system.
TRANSMITTER “POWER” LIGHT NOT ON.
Make sure the wall transformer is plugged into the transmitter.
Make sure the electrical outlet is on.
NO SOUND THROUGH RECEIVERS.
If some of the receivers work, but others don't, check for bad batteries or earphones on the receivers
that aren't working.
Check to see that the receiver frequency matches the transmitter frequency. The frequency sticker is
on the bottom of the transmitter and inside the back cover of the receiver. If they do not match, see
Frequency Change Instructions on page 8 (transmitter) and page 12 (receiver).
If none of the receivers work, check to see if the power is connected to the transmitter and the
“Power” light is on.
Check to see if the Transmitter is connected properly to the sound system. See page 6.
Turn the screwdriver-adjust input level control located on the T17 front panel clockwise to increase the
input signal strength. Check to see that the audio light is flashing occasionally but not continuously.
If you are not using an input signal from a sound system, make sure the Williams Sound microphone
is plugged into the “Mic” jack on the front of the T17 transmitter.
Make sure the antenna is installed and connected properly. See page 6.
INSUFFICIENT RANGE, GOOD RECEPTION NEAR TRANSMITTER, POOR AT A DISTANCE
Check to see if the antenna was installed correctly. If not, correct or replace the antenna. The signal
should be clearly audible at a 300 foot distance.
SOUND THROUGH RECEIVERS IS LOUD, BUT DISTORTED. NOISE (ROOM NOISE OR ELECTRONIC NOISE) SEEMS TO
GROW AFTER TALKING STOPS. AUDIO INDICATOR LIGHT IS CONTINUOUSLY ON.
Turn the screwdriver-adjust input level control located on the T17 front panel counter-clockwise to
decrease the input signal strength. The audio indicator light should flash, not be lit continuously.
SOUND THROUGH THE RECEIVERS IS WEAK AND NOISY. AUDIO INDICATOR LIGHT IS NOT LIT.
Turn the screwdriver-adjust input level control located on the T17 front panel clockwise to increase
the input signal strength. The audio indicator light should be flashing
Increase the input signal level from the sound system.
BUZZING OR HUMMING NOISE IN SOUND SYSTEM.
There is nothing wrong with the T17 Transmitter. One or more pieces of equipment in the sound system
are being disturbed by RF (Radio Frequency) signals produced by the T17. The most likely suspects are
your amplifier, mixer, or tape deck. The RF gets into the other equipment primarily through the power
cord, speaker wires, or unshielded inputs, all of which can act as antennas. Try the following steps.
Move the Transmitter away from the other sound equipment.
Make sensitive equipment more immune to RFI/EMI. The manufacturers of your audio equipment
may offer application notes for this purpose. Williams Sound offers a document giving suggestions
for improving RF immunity in existing audio equipment. (Technical Bulletin: Buzz Or Hum In The
Sound System, FRM 531) Unless you have the necessary technical skills, this is best left to a qualified
electronics repair technician.
