Peavey Assisted Listening Transmitter
The transmitter operates on the 72-76 MHz auditory assistance frequencies. Transmitted field
strength shall not exceed 8000 uV/m at 30 meters.
Maximum FM deviation should not exceed 75 KHz. Transmitter signal pre-emphasis is 75 uS.
Frequency stability is controlled by a phase locked loop synthesizer with crystal reference and
accurate /-.0005% over 0-50 degree s C. The transmitter provides a permanently
mounted telescoping whip antenna.
The FCC approved transmitter is powered by a UL and CSA listed AC wall transformer providing
9V DC input to the transmitter via a 3.5mm DC jack. The transmitter includes a ¼” line-in jack,
mounted on the rear panel and ¼” electret condenser microphone jack with 9V DC power (at 1.0
mA), and mounted on the front panel. Also included, is an adjustable audio level control and a
red LED “Power On” indicator.
PEAVEY Assisted Listening Receiver
The receiver operates on a single frequency in the 72-76 MHz auditory assistance band.
Frequency stability is controlled by a phase locked loop synthesizer with crystal reference and
accurate -.005% over 0-50 degrees C. The receiver de-emphasis is 75 uS. The receiver
provides a 3.5 mm headphone output jack mounted on the top panel.
The receiver is powered by (2) AA batteries. The receiver has an OFF/ON/VOLUME control
mounted on the top panel, LED lamp to indicate battery strength, and an antenna shall be
