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.

þSTEP 3: CONNECT THE POWER
Locate the TFP 036 power supply cord equipped with the 5-pin
DIN connector, then plug the connector into the “Power In” jack
located in the back of the T27. Plug the power supply into the
AC outlet. On power up, the number “8” will scroll across the
T27 display while the system initializes. The system will then
display the default system frequency (72.9 MHz) or the last
selected frequency set by the user.
þSTEP 4: SELECT THE FREQUENCY
The T27 has 17 available channels in the 72-76 MHz band. By
default, the T27 frequency is set to 72.9 MHz. To change the
frequency on the T27, press and release the down “q” or
up “p” frequency selector button until the desired frequency is
displayed. After 3 seconds, the frequency selection will be set,
and the audio will begin transmitting on the new frequency.
NOTE: You can LOCK this selection to prevent others from
accidently changing the frequency.
To LOCK the desired frequency, press and hold both down “q”
and up “p”frequency selector buttons for 3 seconds until the
word “Loc” appears on the display. The frequency is now locked.
Should the user press the frequency selector button while in
“Lock” mode, the word “Loc” will be displayed for 2 seconds.
ToUNLOCK the desired frequency,press and hold both
down “q” and up “p” frequency selector buttons for 3 seconds
until the transmitter displays ”Un” then “Loc” on the display.
The frequency is now unlocked.The user is now free to change
the frequency on the T27 as needed.

þSTEP 5: CONNECT THE AUDIO SOURCE
On the back of the T27, an RCA-type “Audio In” jack is available
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:
Audio Level Indicator LED
1.) Never On =Audio source is TOO LOW.
2.) Blinks occassionally =Audio source is OPTIMAL.
3.) Always on =Audio source is TOO HIGH.
þSTEP 7: LISTEN WITH AN FM RECEIVER
IMPORTANT: The FM receiver being used with the T27
transmitter will need to be on the same frequency as the
transmitter.
Install the receiver batteries, plug in the earphone, turn on the
receiver and walk around the listening area. The signal should be
clear and quite loud when the volume is turned up. See pages
10-13 for detailed receiver instructions.
