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.

have any questions.

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.
