THE PFM T32 OR T31 TRANSMITTER
The PFM Transmitter is a battery-powered body-pack model 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 PPA
Transmitter operates on two AA non-rechargeable alkaline batteries (BAT 001), or two AA
rechargeable NiMH batteries (BAT 026).
MICROPHONES
A noise-cancelling, headband microphone (MIC 086) 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 should be positioned directly
in front of the tour guide's mouth to achieve an optimal signal to noise ratio and so that 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 noise
isolation for hearing protection.
An optional Lapel Clip Microphone can be used in quieter environments like museums or galleries.
The MIC 090 has an omnidirectional pick-up pattern. The MIC 056 has a directional (or cardioid)
pick-up pattern, which will reduce background noise somewhat.
A directional hand-held microphone (MIC 027) is also available for tour guides who prefer to hold
the microphone.
THE PPA R35 RECEIVER
The PPA R35 Receiver is a battery-powered body-pack receiver 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 on/off control, LED power and low battery indicator. The headphone plugs into
the “EAR” jack on top of the Receiver. The PPA R35 Receiver operates on two AA non-
rechargeable alkaline batteries (BAT 001), or two AA rechargeable NiMH batteries (BAT 026).
