SETTING UP THE TRANSMITTER
Your Nady ALD-800 requires minimum installation. Simply place the transmitter on any flat surface,
connect your mixing board to the transmitter’s back panel input (See CONNECTING AUDIO
INPUT below), connect the included power supply (as explained below), and the transmitter is
ready to broadcast to any number of ALD-800 receivers operating on the same channel.

the other end into an AC wall socket. Press power switch 2 . The “power on” LED 3 will light.
Extend antenna 4 fully and position 90 degrees from top of the transmitter.

1/4" mono phone jack accepts an unbalanced line level audio source at zero dBm nominal signal
level. If your mixer has XLR outputs only, you will need an XLR-to-phone plug adapter, available from
most electronics stores and music equipment stores.
USING A MICROPHONE
The Mic jack 7 on the front panel allows wireless cueing of on stage performers.
IMPORTANT: This 1/4” mono phone jack is designed for an electret condenser microphone, and
9V DC power is present at the input jack. If you wish to use a conventional dynamic microphone,
at least 20 dB more gain is required, and a preamp should be used. If a preamp is used, be sure
to have a blocking capacitor (1 mfd) between the preamp output and the E03 mic input. If a
dynamic mic is
