Nady Systems W1KULTBAND1 User Manual

Avoid acoustic feedback (howling or 
screeching) by taking care in selecting 
PA volume, transmitter location and 
speaker placement.

Please also note the pickup pattern 
characteristics of the microphone selected. 
Unidirectional mics are more resistant to 
feedback. However, they pick up sound 
sources best that are directly in front of the 
mic. Also mics that are farther from the 
sound source require more acoustic gain 
and thus are also more prone to feed back 
than close-source mics such as handheld.

If you are not getting audio through the 
system, carefully re-check all setups. 
Especially note that the receiver and 
transmitter must be set to operate on the 
same RF channel. For BT-1KU Bodypack 
transmitter, also confirm that the Power 
Off/Mute/On Switch (34) is not in the Mute 
position. The receiver’s Unbalanced line 
level Out (17) is adjustable so make sure 
the Volume (6) is set properly. 

If you encounter slight receiving interference 
when the transmitter is far from the receiver 
(from other than an operating TV station 
on the same frequency), often it can be 
overcome by adjusting the receiver‘s 
Squelch Control (16) (see Adjusting the 
Squelch). If receiving interference on a 
selected channel with the transmitter 
off, you must reprogram the receiver 
and transmitter to a different channel.

See: Selecting the W-1KU Receiver Volume 
Level / Group / Channel
Selecting the HT-1KU/BT-1KU Transmitter 
Group and Channel

To reprogram, you must first find an open 
channel. To do this, follow the operating 
procedure outlined in Selecting the W-1KU 
Receiver Volume Level / Group / Channel. 
With the associated transmitter off, scroll 
through the groups/channels to find one that 
shows no received signal on the receiver’s 
rF Signal Meter (7) (no bars). Also, there 
must be no bars either on each of the 
three immediately adjacent channels both 
above and below the selected channel 
for optimum interference-free operation 
(i.e. in a field of seven adjacent channel 
total—with the channel used in the middle). 
If operating multiple W-1KU Series systems 
simultaneously, repeat this procedure 
with every new channel being selected, 
with previously tuned systems all on, 
both transmitters and receivers.

Please note that wireless frequencies are 
shared with other radio services. According 
to FCC regulations, wireless microphone 
operations are unprotected from 
interference from other licensed operations 
in the band. If any interference is received 
by any Government or non-government 
operation, the wireless microphone must 
cease operation or change frequencies.
