The ALD-800 from Nady is a versatile VHF wireless assistive listening system that allows you to share an audio source with multiple listeners up to 300' away, ideal for museums, theaters, houses of worship, educational facilities, and more. The system includes a base station transmitter and 4 beltpack receivers. The system can support an unlimited number of receivers (sold separately), allowing you to add as many listeners as you like. The system is pre-tuned to 1 of 8 channels designated for listening assistance by the FCC. This provides clear transmission, and also allows you to set up multiple systems for different applications in the same vicinity.

The transmitter has mic and line level 1/4" input connectors with a manual input gain control. It also offers an automatic level control function. It has an extendable and positionable antenna, and LED indicators to show when the unit is turned on and transmitting audio. The transmitter operates on DC power via the included wall adapter.

Each beltpack receiver is compact and lightweight, fitting easily into a pocket or clipping to clothing. The top panel offers a power/volume wheel with a power LED indicator. A standard 3.5mm headphone jack accommodates the included stereo earbuds, or most other consumer headphones. The receiver uses the headphone cable as the antenna to minimize bulk and weight. Each receiver operates on a single 9V battery.

Note! Additional systems are available separately in 7 other pre-tuned frequencies from 72-76MHz.

    Comments about Nady ALD-800 Wireless Assistive Listening System (AA: 72.1MHz):

    We purchased this wireless system to use in church, for its "assistive listening" purpose. For this it works well.

    The transmitter is easy to connect to a line-out jack on the PA system.

    The receivers show good battery life, and have volume controls with a volume range that can satisfy a wide range of deafness.

    There's a bit of a hiss in the earbuds, especially when the volume is loud.

    The earbuds unfortunately aren't standard. They have a mono, not a stereo, 3.5mm plug. But this problem was easily solved by buying some 38-cent stereo-to-mono adapter plugs (Monoprice order number 7128).

        Comments about Nady ALD-800 Wireless Assistive Listening System (AA: 72.1MHz):

        Don't be fooled. This product is not a good investment, but a waste of money. When I opened my box, one of the receivers was already broken. A second one stopped working a day later, when I tried it for the second time...

        It's simply too cheap. Cheap parts, cheap labour, cheap results. Actually, no results at all!

        I'll finish this with a quote from a Tarantino movie:
        "Long story short, we hear a story too good to be true... it ain't." - Lt. Raine

        Take my advice and buy some real gear.
