System Overview
Thank you for purchasing the Personal PA System
400 from Williams Sound Corporation. The PPA
System 400 is a Narrow-Band FM Listening System
which operates in the 72-76 MHz frequency band.
Designed for hearing assistance in places of public
access, the PERSONAL PA System 400 is for those
who need help overcoming background noise,
reverberation, or distance from the sound source.
The versatile PPA 400 is easily integrated with your
existing sound system or can be used with a
microphone as a stand-alone system.
Your PPA System 400 has two principal parts: the
T17 Transmitter and the R19 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 these
instructions as you begin to use the system. Then
save the manual for questions that arise as you
continue to use your PERSONAL P
A System 400.
