SYSTEM OVERVIEW
Thank you for purchasing the Personal PAValue Pack System from
Williams Sound. The PPAVP 37 System is a Wideband FM
Listening System which operates in the 72-76 MHz frequency band.
Designed for hearing assistance in places of public access, the
PPAVP37 is for those who need help overcoming background noise,
reverberation, or distance from the sound source. The versatile
PPAVP37 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 T27 Transmitter and the PPA
R37 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 1000 feet (305 m).
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 PAValue Pack System.
If you have any problems with this Williams Sound product, please
call us toll-free at 1-800-843-3544.

for connecting a line-level, unbalanced audio source. On the front
of the T27, a 3.5mm “Mic Input” jack is available to connect a
Williams Sound electret microphone. Connect the desired audio
source to the T27 transmitter and proceed to Step 6.
þSTEP 6: ADJUST THE AUDIO LEVEL
With the audio source playing, use a small screwdriver or tuning
wand to rotate the “Adjust” control on the front of the T27: 1)
clockwise to increase the audio level; or 2) counterclockwise to
decrease the audio level. Refer to the audio “Level” indicator
LED on the front of the T27 as you make your adjustments:

USING A RECEIVER WITH A HEARING AID
Williams Sound PPAR37 and PPAR35-8 receivers can be used
with hearing aids using three different methods:
NECKLOOP TELECOIL COUPLER
Neckloops are cords which hang around the neck and couple mag-
netically with T-Coil equipped hearing aids.
SILHOUETTE TELECOIL COUPLER
These telecoil couplers are worn behind the ear, right next to tele-
coil-equipped hearing aids.
DIRECT AUDIO INPUT (DAI) CORD
DirectAudio 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.
þRegular users purchase their own receiver and take care of
their own batteries and earphone.
þSome facilities label the receiver and earphone with the names
of regular users so each person uses the same receiver and
earphone.
þUshers 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.
þThe receivers can be stored in a multiple compartment storage
case with a credit card or driver's license left as collateral for
the receiver.
þRegular 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 prop-
er setup and installation of your system.
TRANSMITTER FREQUENCY DISPLAY (LED) NOT LIT.
þMake sure the wall transformer is plugged into the transmitter.
þMake sure the electrical outlet is on.
NO SOUND THROUGH RECEIVERS.
þIf some of the receivers work, but others don't, check for bad bat-
teries or earphones on the receivers that aren't working.
þCheck to see that the receiver frequency matches the transmitter
frequency. On the transmitter, the frequency is illuminated on the
LED panel on the front of the unit. On the receiver there may be
asticker on the inside of the battery door of the receiver. If these
frequencies do not match, see Frequency Change Instructions on
page 6 (transmitter) and page 11 or 13 (receiver).
þIf none of the receivers work, check to see if the power is con-
nected to the transmitter and the frequency display on the front of
the transmitter is illuminated.
þCheck to see if the transmitter is connected properly to the sound
system. See page 7.
þTurn the screwdriver-adjust audio input level control on the front
panel of the T27 transmitter clockwise to increase the audio level.
Make sure that the audio light is flashing occasionally but not
continuously.
þIf 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 T27 transmitter.
þMake sure the antenna is installed and connected properly.See
page 5.
INSUFFICIENT RANGE,GOOD RECEPTION NEAR TRANSMITTER,POOR AT A DISTANCE
þCheck to see if the antenna was installed correctly. If not, correct
or replace the antenna. The signal should be clearly audible at
least 100 ft with line of site to transmitter antenna.
þCheck to make sure no other transmitters (or other devices) are
transmitting on the same frequency (channel).

18
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.
þTurn the screwdriver-adjust audio level control on the front of
the T27 transmitter counter-clockwise to decrease the audio
level. The audio indicator light should flash occasionally, but
not be lit continuously.
SOUND THROUGH THE RECEIVERS IS WEAK AND NOISY.
þTurn the screwdriver-adjust audio level control located on
the T27 front panel clockwise to increase the input signal
strength. The audio indicator light should flash occasionally.
þIncrease the input signal level from the sound system.
BUZZING OR HUMMING NOISE IN SOUND SYSTEM.
þThere is nothing wrong with the T27 Transmitter. One or more
pieces of equipment in the sound system are being disturbed
by RF (Radio Frequency) signals produced by the T27. 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:
þMove the Transmitter away from the other sound equipment.
þMake sensitive equipment more immune to RFI/EMI. The
manufacturers of your audio equipment may offer applica-
tion notes for this purpose. Williams Sound offers a docu-
ment 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 neces-
sary technical skills, this is best left to a qualified electronics
repair technician.
