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 within +/-.0005% over 0-50 degrees 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 line-in jack, mounted on the rear panel and 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 within +-.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 integral to the earphone/ear bud cord
