INTRODUC TION
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 24 groups and 40 channels in each
frequency band. Band-1 748-7773MHz, Band-2 795-820MHz, and Band-3 846.000-871MHz. 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.

SYSTEM OPERATION
3. UWS-1K Receiver Buttons Function
Each time the Set Button (19) is pressed the LCD Menu (10) display will cycle through the set up
menus in this order: MAIN MENU->CHANNEL->GROUP->SQL->MAIN MENU and then repeat.
The selected function will flash for 20 seconds before returning to the MAIN MENU. To exit from any
setting menus, press Transfer Button (18) once.
When pressing the Transfer Button (18) once while MAIN MENU is displayed, the Power LED (9)
will flash quickly. This LED indicates IR transmission is in progress. Press Transfer Button (18)
again to stop or it will expire in 20 seconds automatically.
The UP-DOWN Rocker button (20) works only while setting the menu. At Power OFF the UWS-1K
receiver will store the last settings entered and re-display them at Power ON. It can be reprogrammed to any new group/channel, and SQL level. The default factory setting is Group 13, Chan-
nel 01, and SQL 01.
4. Selecting the UWS-1K Receiver Group, Channel,
& SQL Setting
See Section 26 below (RF Interference and Finding Open Channels) also for help in finding desired
channel(s) of operation in setting up your system(s).
Choose the UWS-1K operating frequency by selecting one of 25 Groups and one of 40 Channels
in each group that are determined to be desirable open channels as per the procedure outlined
in Section 26. The first two large digits on the left are the GROUP (11) and the second two large
digits on the right are for the CHANNEL (11). Press the Set Button (19) once to enter the CHAN-
NEL (11) set up mode and then press the UP-DOWN Rocker button (20) once for single stepping
through the channels or hold continuously for faster channel selection. Select one of 40 channels
available from the CHANNEL (11) menu and advance to GROUP (11) set up mode by pressing Set
Button (19) or press Transfer Button (18) to exit.
Press the Set Button (19) again to enter the GROUP (11) set up mode and then press the UP-
DOWN Rocker button (20) once for single stepping through the groups or hold continuously for
faster group selection. Select one out of 25 groups from the GROUP (11) menu and advance to
SQL (14) set up mode by pressing Set Button (19) or press Transfer Button (18) to exit.
Press the Set Button (19) once to enter the SQL (14) set up mode and then press the UP-DOWN
Rocker button (20) once for single stepping through the SQL (RF muting/squelching) levels or
hold continuously for faster SQL level selection. Select one out of 50 levels from the SQL menu and
advance to Exit set up mode by pressing Set Button (19) or press Transfer (18) to exit.
Press Set Button (19) once to exit or press Set (19) twice to restart selection of a different channel, group, or SQL level. When the exit mode is reached, the new group/channel/SQL selected are
programmed.
5. UH/UB-1K Transmitters Buttons Function
Press the Power Button (23/32) for more than 2 seconds to power up the transmitter (please also
see section 14 & 18 below). It will now be in standby (audio input muted) mode. Press the Power
Button (23/32) again briefly to unmute or to mute the audio.

SYSTEM OPERATION
6. Selecting the UH/UB-1K Transmitters Group &
Channel Setting
Both the UH/UB-1K transmitters have to be programmed for the channel and group selected on
the UWS-1K receiver via the IR reception link between the receiver and transmitter during the first
20 seconds after the transmitter is powered up. As soon as the transmitter LEDs light up indicating Power ON, the Transfer Button (18) on the UWS-1K receiver must be pressed once while the
MAIN MENU is being displayed. The Power LED (9) of the receiver will flash quickly indicating IR
transmission to the transmitters of the Group and Channels selected on the receiver is in progress.
Successful transfer is complete when the Signal Strength indicator on the receiver’s LCD Display
(10) indicates a received signal from the transmitter being programmed. Press Transfer (18) again
to stop when this happens or just let it expire in 20 seconds automatically. (Important note: there is
no other way to program the Group and Channel selected in the UWS-1K receiver into the UH/UB1K transmitters so the above procedure must be followed carefully.)
UWS-1 K RECEI VER
7. Rack-mounting the Receiver
There are two options available for rackmounting the UWS-1K: single or side-by-side with another
UWS-1K receiver.
a. Single mounting: Just attach the optional Rack Ears (1) to each side slot and tighten with
supplied screws (as shown).
b. Side-by-side mounting: Attach the two optional Join Pieces (2) and tighten the four supplied
screws. Then attach the rack ears to each side slot and tighten with supplied screws (as
shown).
(Note: Do not mount the receiver on a rack directly above an amplifier or other source of high heat.
This could degrade the performance of the UWS-1K. Always ensure adequate airflow and heat dis-
sipation in any rack configuration.)
8. Installing Antennas
Install antennas by connecting the two Antennas (3) included with your system to the two RF
Screw-On Connectors (4) located on the back of your UWS-1K receiver. The optimal positions
of the antennas are 45 degrees from the receiver and 90 degree from each other. For maximum
range, it is always best to maintain a line of sight (no obstructions) between the receiver antennas
ant the transmitter at all time whenever possible.
9. Powering the Receiver
To power the receiver, plug the AD-DC adaptor (16.5VDC/0.4A) provided into the DC Input Jack
(5) on the back of the receiver. Then plug the adapter into an AC outlet. (Note: Any 16.5VDC source
with 400mA capacity can also be used.) Connect either the XLR Balanced (6) or 1⁄4” Unbalanced
Output (7) to your mixing board, effect, or amplifier.
To turn ON, press the Power Switch (8) for 2 second. The Power LED (9) will light and the LCD
Display (10) will show the Group (11), Channel (11) assignment, RF Level Meter (12), Diversity
(13), and the audio AF LED (15) displays (when the transmitter is activated).
To turn OFF, press the Power Switch (8) for 3 seconds and release. The receiver will turn off.
