Personal PA ™ Value Pack System Wide-Band FM Wireless Listening System Transmitter Model PPA T27 Receiver Model R35 QUICKSETUPGUIDE MFRM 010A Model PPA VP ® 2 SYSTEMOVERVIEW Thank you for purchasing the Personal PA Value Pack System from Williams Sound Corporation. The PPA VP 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 is for those who need help overcoming background noise, reverberation, or distance from the sound source. The versatile PPA VP 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 R35 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 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 PA Value Pack System. If you have any problems with this Williams Sound product, don’t hesitate to call us toll-free at 1-800-843-3544.
