Overview

A 1000-channel select UHF dual wireless system for simultaneous operation of two transmitters.

The Nady 2W-1KU wireless system has the best performance and price value in
professional UHF wireless, offering clear-channel, frequency-agile operation on the UHF band for interference-free performance in any application or locale. The Nady 2W-1KU wireless system has two independent UHF receivers each delivering 1000 user-selectable channels with AUTO-SCAN for easily locating clear channels, frequency synthesized in pre‘programmed 00-09 groups and 00-99 channels in the (U.S.) Band 1: 672.000- 696.975MHz, (Int.) Band 2: 795.000-819.975MHz ranges. The Nady 2W-1KU wireless system features proprietary companding and low-noise circuitry for an industry-best 120dB dynamic range, and the clearest, most natural sound available in wireless today.

BT-1KU Bodypack Transmitter
The Nady BT-1KU bodypack transmitter offers a choice of three versions: LT, LT/HM, or GT, and features road worthy all-metal case; power Off/Mute/On switch; flexible external antenna rod; and mini locking connector for lapel (LT), Headmic (LT/HM), or instrument (GT) applications. An LCD displays indicates selected Group, Channel, Audio Input Levels, and Battery level status; transmitting High/Low RF power switch for optimizing distance operation depending on application; and operation with two AA batteries (alkaline or rechargeable NiMH) for longest reliable, economical battery life.

2W-1KU Receiver:
The Nady 2W-1KU Receiver offers unsurpassed state-of-the-art PLL UHF performance with 120dB dynamic range and operation up to 500 feet line-of sight. It has two complete and independent wireless receivers with 1000 user-selectable UHF frequencies for simultaneous operation of two transmitters and true Diversity circuitry with two complete front ends per receiver for maximizing range and most effective elimination of signal dropouts. The AUTO-SCAN function easily locates clear channels and the ASC (Auto-Sync Channel) IR download feature sends selected Group/Channel information to transmitter via IR sender for easy frequency synchronization. Sophisticated IF filtering permits simultaneous operation of multiple systems in the same location.
