Personal PA® DSP FM Wideband Transmitter 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.

Personal PA® DSP FM Wideband Transmitter Avoiding Hum in the Audio (as a Result of a Ground Loop) A hum created by a ground loop can often be eliminated by connecting a capacitor in series with the audio line shield to the transmitter’s ground. This method also maintains good RF shielding. Determining the effectiveness of this method for your installation usually requires some experimentation. Necessary capacitors can be obtained from Williams Sound or from any electronic parts supplier. See Figure 4.
Personal PA® DSP FM Wideband Transmitter Connecting the T45 to other Devices The Analog LINE/MIC Input jack can be used with standard pro audio electronics such as Condenser Microphones (15-45v) or an analog line output from a mixer. The combination jack accepts either XLR or 1/4”. This source must be configured in the menu before plugging the source into the jack. The RCA Audio Line Output jack can be used for monitoring, recording, or routing processed audio to another sound system.

Personal PA® DSP FM Wideband Transmitter General Setup Instructions 1. Position the PPA T45 transmitter near the sound system or mixer from which it will receive audio. It should be free from metallic objects that might interfere with the antenna signal. 2. If the transmitter is free-standing (not rack-mounted), install the ANT 025 whip antenna. Gently thread the ANT 025 onto the stud recessed in the hole on the top of the transmitter (Figure 2) and extend it all the way.

The facility labels a receiver and earphone for each regular user. The facility maintains the units. 3.
Personal PA® DSP FM Wideband Transmitter Troubleshooting The T45 “RF” (On Air) Indicator is not on • Make sure the transformer (TFP 048) is plugged into the transmitter and any remote power switch is on. • Make sure the electrical outlet is on. • Make sure the power button on the front of the T45 is pressed to the “on” position. • Make sure the 24 VDC power supply is working. • Make sure the RF output is not set to “OFF.
Personal PA® DSP FM Wideband Transmitter Insufficient range, good reception near transmitter, poor at a distance • Check to see if the transmitting antenna was installed as specified in this manual. If not, correct or replace the antenna. The signal should be clearly audible up to at least a 100-foot distance with the ANT 005 or ANT 025. • Make sure the transmitting antenna is not in an unsuitable location.
Personal PA® DSP FM Wideband Transmitter Remote Control is not working over Wi-Fi • Please note: If you have a network system administrator, please contact them first before attempting to troubleshoot the network yourself. If you don’t have a system administrator, the following steps are things you can try on a small, non-managed network. • This situation is most often caused by the mobile device losing connection to the router when the Wi-Fi on the mobile device has been turned off. 1.
Personal PA® DSP FM Wideband Transmitter Remote Control is not working over the hardwired Ethernet network • Please note: If you have a network system administrator, please contact them first before attempting to troubleshoot the network yourself. The following steps are things you can try on a small, non-managed network. • In this situation you have to check the entire signal path between the control device (laptop or desktop computer) and the T45. You can save some time by “pinging” the router and T45.
