INTRODUCTION
Thank you for choosing the Nady UWS-1K Series wireless system, and congratulations on your
choice. The Nady UWS-1K series systems are by far the best performance and price value in
professional UHF wireless. They offer clear channel operation on the wide-open, uncluttered UHF
band for interference-free performance in any application or locale. The UWS-1K series delivers
1000 user switchable channels, frequency synthesized in 25 groups and 40 channels in each fre-
quency band. Band-1 748-773MHz, Band-2 795-820MHz, and Band-3 846-871MHz. The UWS-1K
Series 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.
