FM radio signal
The FM Tour Guide System is a portable, high-performance, wireless system composed of the PPA
T16 Transmitter and PPA R7 Receivers and designed for use in hearing assistance applications. The
system allows one-way transmission of a tour guide’s voice to hearing impaired group members by
using an FM radio signal. Using the system helps to overcome background noise and distance from
the person speaking. The Tour Guide System can be used for large or small tour groups, in noisy or
quiet environments. Under FCC regulations, the Williams Sound FM Tour Guide System may only be
used for hearing assistance.
The T16 Transmitter:
The T16 Transmitter is a battery-powered belt pack that is used with a microphone to pick up the
tour guide's voice. The Transmitter produces an FM radio signal to broadcast the tour guide's voice
to the receiver units. A simple slide switch on top of the transmitter turns the unit on or off. The T16
operates on a 9 Volt alkaline disposable battery or a 9V NiMH rechargeable battery.

Microphones:
A noise-cancelling, headset microphone (MIC 044) is the standard microphone. The noise-cancelling microphone helps to reduce background sounds in noisy environments. The microphone
plugs into the "MIC" jack on top of the Transmitter. The microphone is positioned directly in front of
the tour guide's mouth for maximum signal to noise ratio and so head movement does not affect
the loudness of the signal. The microphone cord acts as the transmitting antenna.
Optional Microphones:
An optional Hearing Protector Headset Microphone (MIC 036) is also available for extremely high
noise environments. It features ear muffs that completely cover both ears and provides 24 dB NRR
of attenuation for hearing protection. An optional Lapel Clip Microphone can be used in quieter
environments like museums or galleries. The MIC 081 has an omnidirectional pick-up pattern. The
MIC 054 has a directional (or cardioid) pick-up pattern, which will reduce background noise somewhat. A small hand-held microphone (MIC 026) is also available for tour guides who prefer to hold
the microphone.
The R7 Receiver:
The R7 Receiver is a battery-powered belt pack that is used with a headphone to hear the signal
produced by the Transmitter. The Receiver is pre-tuned to the Transmitter and has a user-adjustable
volume control. The headphone plugs into the "EAR/CHG" jack on top of the Receiver. The receiver
is turned on by rotating the volume control wheel. The receiver operates on a 9 Volt alkaline disposable battery or a 9V NiMH rechargeable battery.

HED 008 Hearing Protector EAR 022 Surround Style EAR 014, EAR 013 Mini Earphone
Headphones and Earphones:
The HED 001 Lightweight Headphone is the standard headset for the Tour Guide System. It offers
excellent sound quality and wearing comfort. The foam earpads may be removed for cleaning or
replacement. Replacement pads are part number HED 003-10.
The headphone plugs into the "EAR/CHG" jack on top of the Receiver. The headphones are wired
with a mono plug. If a stereo headphone is substituted, it will only work on one side of the headphone.
Optional Headphones and Earphones:
The HED 008 is a heavy-duty, hearing-protector headset. The HED 008 earmuffs completely cover
the ears and provide 24 dB NRR noise attenuation for hearing protection in high noise environments.
The EAR 022 Surround Earphone offers excellent sound quality in a unique style that hangs on the
ear. It is easy to keep clean since the earphone does not enter the ear. It is not recommended for
high noise environments.
The EAR 013 and EAR 014 are single and dual Mini Earphones. The earbud-style features a foam
covering that fits in the outer ear. The foam pads can be removed for cleaning or replacement.
Replacement pads are part number EAR 015-10.
Earpad Care:
Foam earpads may be removed and washed in a mild detergent, rinsed thoroughly, and air dried.
Replacement pads are also available from Williams Sound.
