System Connection Overview
The PPA T45 is an FM Wide-Band transmitter operating in the 72-76MHz bandwidth. Compatible Williams Sound receivers
include PPA R38, PPA R37, PPA R35-8 body packs and the PPA R1600 remote speaker.
Developed for hearing assistance in places of public access, the PPA T45 is designed for those who need help overcoming
background noise, reverberation, or distance from the sound source. It includes a complete audio processor optimized for the
needs of hearing impaired persons and is easily integrated with your existing sound system. The PPA T45 can also be used with a
microphone as a stand-alone system.
Your PPA T45 transmitter operates just like an FM radio station. The transmitter takes audio directly from a microphone or sound
system. This audio is then broadcast over an FM radio signal. FM radios can be worn by listeners or an AC powered amplified
speaker with built in receiver can be utilized as needed. The broadcast can be received up to 1000 ft from the transmitter *. This
allows listeners to sit anywhere in the area and listen to the broadcast at the volume level they need without disturbing others
around them.
Two models are available - one with Ethernet control (PPA T45NET) and one without Ethernet control (PPA T45). Ethernet control
allows the transmitter settings to be changed over a network with hard-wired or wireless devices (Figure 1).
*Range is dependent on the environment.
