The Nady Systems RFD Hearing Assistance Receiver (HH Channel) features advanced design and high-quality construction and is fully compliant with ADA regulations. The pre-tuned portable wireless receiver is a single-channel unit that operates on 1 of 8 frequencies in the 72 to 76 MHz radio band, with wideband modulation for high quality audio. The RFD Hearing Assistance Receiver can be used both outdoors and indoors in bright light without affecting performance.
Frequency stability is controlled by a phase locked loop synthesizer with crystal reference and accurate within ±.005% over 32 to 122°F (0 to 50°C). The receiver de-emphasis is 75 µs. The receiver provides a 3.5mm headphone output jack mounted on the top panel.
This pocket-sized Nady receiver works in conjunction with the ALD-800T HH-Channel Transmitter (sold separately) and has adjustable volume control and comfortable, high performance earphones.
The receiver is powered by a 9V alkaline battery. It has an Off/On/volume control mounted on the top panel LED lamp to indicate battery strength, and an antenna is integral to the earphone/earbud cord.
