INTRODUCTION
Thank you for choosing the Nady U-41 QUAD wireless system, and congratulations on your choice.
The Nady U-41 QUAD Wireless systems are by far the best performance and price value in profes-
sional UHF wireless. It offers clear channel operation on the wide-open, uncluttered UHF band
for interference-free performance in any application or locale. The U-41 QUAD delivers 4 discrete
channels in frequency from 796.30 MHz to 803.30 MHz. The U-41 QUAD Wireless system feature
Nady’s proprietary companding and low noise circuit for an industry best 120dB dynamic range, and
the clearest, most natural sound available in wireless today.
USING THIS MANUAL
This booklet gives instructions for the operation of the U-41 QUAD Wireless systems: The U-41
QUAD receiver, transmitter models UH-4 Handheld Microphone, UB-4 bodypack Lavalier Micro-
phone, and Link-4 Snap-On microphone transmitters.
This manual will first explain the benefits of the U-41 QUAD Wireless System and then will take you
step by step on how to operate your new system. Each section will give you detailed information.
Also, included in this manual are the frequency chart, microphone-wiring guide, system specifica-
tions and servicing information.
