PERSONAL PA® FM Tour Guide Systems

System Overview

Thank you for purchasing the TGS PRO 737 or TGS PRO MULTI Personal PA® Tour Guide System from Williams AV.
The Personal PA® Tour Guide System is a portable, high-performance, wireless listening system. It is composed of a PPA T46
Transmitter, microphone, and optional PPA R37 or R35-8 receivers equipped with headphones or earphones. The system
allows one-way transmission of a tour guide’s voice to group members using an FM radio signal. Using the system helps
group members overcome background noise and distance from the person speaking. The Personal PA® Tour Guide System can be used for large or small tour groups, and in noisy or quiet environments. Your Personal PA® Tour Guide System has two principal parts: the transmitter and the 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 and headphones are used to pick up the broadcast up to 150 feet away. See Figure 1. To avoid difficulties, please read through these instructions as you begin to use the system. Then save them for questions that arise as you continue to use your system. If you have problems with the Personal PA®
Tour Guide System, don’t hesitate to call Williams AV at 1-800-843-3544 or +1 952 943 2252.

72-76 MHz Wideband Transmitter

PPA T46 Overview
Much like a miniature radio station, the PPA T46 transmitter broadcasts over an FM radio signal. Receivers are used to pick up the broadcast up to 150 feet away. The system helps large or small groups overcome background noise and distance to clearly hear the speaker. The PPA T46 FM transmitter broadcasts voice and/or audio programs on one of 17 available channels, 72-76 MHz.
Listeners use PPA R35-8 / PPA R37 receivers equipped with headphones, earphones, or neck loops to hear the broadcast.
(An R1600 speaker can also be used.) The PPA T46 features a convenient, dual preset mode that allows users to set separate channel/volume/auxiliary gain levels for each preset and then toggle back and forth between them. The OLED user interface on the PPA T46 is an easy-to-read digital display and active read-out. The unit also features a flexible microphone and auxiliary inputs, push-button on/off/ mute controls, settings lock, and selectable compression. To avoid difficulties, please read through these instructions, and keep them for reference.

Using the System

The nominal operating distance between the transmitter and receiver is about 150 feet. The operating range will vary in different
buildings and surroundings. In some locations, the signal may momentarily disappear. This is called a “drop-out” and is due to
the reflection and cancellation of the radio signal. Moving a few feet should restore the signal. Keep the transmitter and receiver units at least 3 feet apart. If the transmitter gets too close to a receiver, it may overload the receiver, causing noisy reception or blocking of the signal.
Do not use more than one transmitter on the same channel (frequency) at the same time unless they are physically separated by
more than 200 feet. Operating more than one transmitter on the same channel at the same time in the same place will result in
interference.

Using Multiple Systems for Multiple Groups:
For multiple tour groups within the same facility, multiple Tour Guide Systems may be operated on the same channel at the
same time by maintaining physical separation of more than 200 feet between groups. The physical separation of groups takes
advantage of the FM capture effect which causes receivers to lock onto the closest transmitter.

Figure N: Tour Guide Group Separation

In Case Of Difficulty

If your Tour Guide System is not working, check the following:

1.  Read through the manual and user guide carefully to verify the proper setup and installation of your system.

2. Make sure the batteries are fresh or completely charged and that the “plus” and “minus” terminals are installed correctly.

3. If the rechargeable batteries work for a short period of time (less than 1 hour) even after they are fully charged, they must be
   regenerated. Leave them in the receiver or transmitter with the unit turned on for 5 – 6 hours. Then turn the receiver or transmitter off, place it in the charger, and fully charge the receiver and transmitter (refer to charger instruction manual). This should restore normal battery life. Rechargeable batteries will gradually lose their capacity over time and may need to be replaced every 1-2 years.

4. Make sure the microphone is plugged into the Transmitter and the earphone or headphone is plugged into the Receiver.

5. Move the transmitter and receiver closer together. You may be out of range. When using the system indoors, it’s normal for the signal to momentarily disappear in certain locations. This is called a “drop-out.” Moving a few feet will restore the signal.

6. Do not try to use more than one transmitter on the same channel in close proximity to each other. MORE THAN ONE
   TRANSMITTERS ON THE SAME CHANNEL WILL RESULT IN INTERFERENCE IF THEY ARE CLOSE TOGETHER. Keep the transmitters at least 200 feet apart or use separate channels for each system used.

7. If you are still hearing interference on the receivers, turn the transmitter off and listen with a receiver. If you hear the interference with the transmitter off, you need to change to a clear channel (see pages 8-9). Call your Williams AV
   representative at 1-800-843-3544 or +1 952 943 2252 for details.

8. Make sure the transmitter and receiver(s) are on the same channel/frequency.

Troubleshooting

•  Verify Transmitter and Receiver are both ON
• Verify Transmitter and Receiver are both on the same channel/frequency.
• Verify Transmitter mic is not muted.
• Verify mic volume and aux volume levels – try turning them up.
• Verify the microphone with the cord is plugged in.  The cord acts as the transmitting antenna.
• If using the Aux input, verify the aux source is playing, and the level indicator (on the front of the transmitter) is pulsing.

Can’t hear the person speaking above the

room noise

|

• Adjust the microphone volume in the menu
• Reposition the microphone closer to the mouth

Limited Range|

•  The microphone cord is the transmitting antenna.  Make sure it is not coiled up or obstructed, and that it is a Williams AV-approved mic.
• Verify the transmitter’s distance from the receiver – try bringing them closer.
• Verify there are no other transmitters in the area on the same (interfering) channels.
•  Transmitter batteries low?   Receiver batteries low?  Try new batteries and if this works, recycle the old ones.

Feedback (squealing)|

• Lower the microphone volume in the menu
•  Increase the distance between the microphone and the listening speaker
