Overview
Thank you for purchasing the Personal PA System
500 from Williams Sound Corp. The PPA System
500 is a Narrow-Band FM Listening System which
operates in the 72-76MHz frequency band. Designed
for hearing assistance in places of public access, the
PERSONAL PA System 500 is for those who need
help overcoming background noise, reverberation, or
distance from the sound source. The versatile PPA
500 is easily integrated with your existing sound
system or can be used with a microphone as a stand-
alone system.
Your PPA System 500 has two principal parts: the
T20 Transmitter and the R19, R19-4, or R19-6
Receivers. 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 this manual
as you begin to use the system. Then save it for
questions that arise as you continue to use your
PERSONAL PA System 500.
If you have any problems with this Williams Sound
product, don’t hesitate to call us toll-free at
