Safety Warnings
HEARING SAFETY
CAUTION!
Many Williams AV receivers are designed to amplify sounds to a
high volume level, which could potentially cause hearing damage
if used improperly. To protect your hearing and the hearing of
others:
1. Make sure the volume is turned down before putting on the
earphone or headphone—only then adjust the volume to a
comfortable level.
2. Set the volume level at the minimum setting that you need to
hear.
3. If you experience feedback (a squealing or howling sound),
reduce the volume setting and move the microphone away
from the earphone or headphone.
4. Do not allow children or other unauthorized persons access to
this product.
BATTERY SAFETY AND DISPOSAL
CAUTION!
Williams AV T46 transmitters are supplied with non-rechargeable
alkaline batteries. Do not attempt to recharge non-rechargeable
batteries; they may explode, release dangerous chemicals, cause
burns, or cause other serious harm to the user or product.
PACEMAKER SAFETY
CAUTION!
If you have a pacemaker or other medical device, make sure
that you are using the Williams AV transmitter in accordance with
safety guidelines established by your physician or the pacemaker/
medical device manufacturer.
Servicing or attempting to service this device will void the warranty
Refer servicing to qualified personnel. Servicing is required when
the system has been damaged in any way: if liquid has been
spilled or objects have fallen into the unit, if the unit has been
exposed to moisture, if the unit does not operate normally, or if the
unit has been dropped.
System Overview
Thank you for purchasing the PPA T46 Personal PA™ Body-pack
Transmitter.
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 neckloops 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 flexible microphone and
auxiliary inputs, push-button on/o/mute controls, settings lock and
selectable compression.
To avoid diculties, please read through these instructions, and
keep them for reference.

Quick Setup
1. Open the battery compartment. Slide the battery selection
switch to the correct position for the type of batteries that will
be used. Use “Alkaline” for non-rechargeable batteries, “NiMH”
for rechargeable NiMH batteries (only). (FIG. A) IMPORTANT:
If the battery switch is not in the correct position, damage may be
caused to the unit.
2. Install the AA batteries. Be sure to observe proper polarity
(+/-). Damage due to improper battery installation may void
the warranty on the product. The battery icon on the display
and the “Power On” LED on top of the unit will flash when the
batteries are getting low; you may continue to use until the unit
quits operating, then replace or recharge the batteries.

3. Plug in the microphone cord (sold separately) using the “Mic
Jack” on top of the transmitter (Figure B).
4. Optionally, plug in a desired audio source such as a CD or
MP3 player using the “Auxiliary Input” jack (WCA 087 stereo
auxiliary input cable included). If mic and auxiliary sources
are used together, the audio will be mixed. If only an auxiliary
source is desired, the mic can be muted. Do not remove the
mic from the “Mic Jack” as the microphone cable is also the
transmitting antenna. (Figure B)
5. Turn the unit on: press and hold the “ON/OFF/MUTE” button for
three seconds. The “Power On” indicator will illuminate green.

6. Select the desired operating frequency. Refer to the
following channel selection chart. Make sure the transmitter
and receiver channels match. Up to eight T46’s can operate
simultaneously on dierent channels. If this is desired, set
each T46 to 8-channel mode (see Advanced Settings, Step 4).
The frequencies in 8-channel mode correspond to the R35-8
channel set shown in the chart. This preset eight channel/
frequency selection is the only configuration that will allow
simultaneous eight channel use. (FIG. C)

Troubleshooting
Problem Solution
Can’t hear the person speaking/no audio · 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 cord is plugged in. The cord acts as the transmitting
antenna.
- Similar to the transmitter, the receiver earphone/headphone cord is the receiving
antenna. Verify the earphone/headphone cord is plugged in all the way on the
receiver.
· 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 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
