System Overview
Thank you for purchasing the Personal PA Value Pack System from Williams
Sound. The PPA VP 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 PPA VP 37 is for those who need help
overcoming background noise, reverberation, or distance from the sound
source. The versatile PPA VP 37 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 difculties, 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, please call us
toll-free at 1-800-843-3544.

rules allow only the use of antennas provided by Williams Sound. To use
a remote antenna supplied by Williams Sound, the antenna cap may be
removed by turning it counter-clockwise with a pliers or wrench. Please

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.
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 “ ” or up “
” 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 “ ” and up
“ ” 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.
To UNLOCK the desired frequency, press and hold both down “ ” and up
“ ” 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
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 3.5 mm “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.

6. Adjusting the Audio Source. 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
Never On = Audio source is TOO LOW.
Blinks occasionally = Audio source is OPTIMAL.
Always on = Audio source is TOO HIGH.
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.
