System Operation
• Short press (~ 1 second) to transfer the
selected frequency information from
the receiver to the transmitter for easy
synchronization prior the transmitter can
be used. When short pressing the ASC
IR Sync button while the main menu is
displayed, the IR leD (1) will light up red
and stay for about three seconds. This
indicates IR transmission is in progress
and IR data is transferring during this
period. A transmitter should be used
at this time to receive data from the
receiver (see IR Sync Programming
in Programming sections of HT-1KU
and BT-1KU transmitter sections).
Upon successful data transferred (usually
in about three seconds) the IR LED stops
and the transmitter’s backlight will light
up and the transmitter will transmit a
radio signal on the same channel as the
receiver. The Signal Strength and Diversity
indicators on the receiver’s LCD display
will then light up, indicating that the IR link
is completed. If manual channel selection
is preferred, skip this selection.
2W-1KU Receiver
Buttons Function
The Power Button (6) is used to turn both
receivers ON or OFF at the same time.
When this power button is pressed, the blue
backlights on the lCD Displays (7) will light
up indicating the receivers are on. Press the
Power button again to turn off the receivers.
The LCD will display “OFF” then the backlight
will turn off indicating the receivers are off.
At power-off the 2W-1KU receivers will
store the last settings entered and re-display
them at power-on. It can be reprogrammed
to any new Group/Channel, or Volume
level. The default factory setting is Group
04 (Receiver 1) and 05 (Receiver 2), and
Channel 00, Volume 63 for both receivers.
The (Up) or (Down) Buttons (4) are active
while in the Set mode, or can be used to
change Volume level (11) at anytime.
When the Set Button (3) is repeatedly
pressed the LCD display menus will cycle
in the following order:
Note: If you are using multiple transmitters at the
same location, set up the first transmitter and leave
it ON and keep it 3 ft. away from the receivers.
Then start AUTO-SCAN on the second receiver.
This avoids duplicate selection of the same channel
as already selected for the first receiver.

Installing antennas
Install antennas by connecting the two
antennas (20) included with your system
onto the two RF Connectors (15) located
on the back of the 2W-1KU receiver. The
two antennas must be installed in order to
the diversity circuit to work properly. The
optimal positions of the antennas are 45°
from the receiver and 90° from each other.
For maximum range, it is always best to
maintain a line-of-sight (no obstructions)
between the receiver antennas and the
transmitter at all times whenever possible.
Choose the 2W-1KU operating frequency
by selecting one of ten Groups (9) and one
of 100 Channels (10) that are determined to
be desirable open channels. Press the Set
button to enter the Group setup mode and
the Group icon will flash, then press the
Up/Down button once for single stepping

button to confirm the selection and the
display will return to the main menu. For
detail how to IR Sync the TX, see IR Sync
Programming in Programming sections of
HT-1KU and BT-1KU transmitter sections.
Powering the Receivers
To power the receivers, plug the supplied
AC/DC Power Supply (19) adapter into
the DC Input Jack (14) on the back of the
receivers, then plug the adapter into an
AC outlet.
Note: Any 16-18VDC power source with 800mA
minimum capacity can also be used.
To turn on, press the Power Button (6)
for two seconds. The lCD Display (7) will
light (showing Group, Channel, RF Level
Meter, Diversity, and Output Volume).
The 5-segment aF leD Tree (5) will display
the audio level when the transmitter is on
(audio is transmitted). To turn off, press the
Power button for two seconds. The LCD will
display “OFF” then the backlight will turn
off indicating the receivers are off.
Rack-mounting the Receiver
The Nady 2W-1KU dual receiver wireless
system includes a rackmount kit for front
antennas mounting. Simply attach the “L”
shape Rack ears (21) to the unit with the
supplied screws.
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
2W-1KU. Always ensure adequate airflow and
heat dissipation in any rack configuration.
Connect either the ¼” Unbalanced SUM line
Out (18) or each XlR Balanced Mic Outs (17)
to your mixing board, effect, or amplifier
inputs (See Connecting the Audio Outputs
section).

adjusting the Squelch
Connecting the audio Outputs
The 2W-1KU receiver has one Unbalanced
audio SUM Out (18) adjustable line level
audio output and two Balanced XlR Mic
Out (17) fixed level jacks and each works
independently per channel. The Unbalanced
Audio Out is controlled by (Up) or
(Down) Buttons (4). The receiver Volume
Display (12) will indicate the level selected.
For unbalanced output, plug a ¼” mono
(Tip/Sleeve) audio cable into the Unbalanced
Audio Out jack and plug the other end into
your mixing board or amplifier. When using
the BT-1KU instrument transmitter system,
connect the Unbalanced Audio SUM Out
directly to your instrument amp or preamp.
At maximum receiver volume setting, as
indicated by the Volume display, the system
output is approximately +4dB higher than a
direct cord-to-amp connection.
In normal operation, each 2W-1KU receiver’s
Mute Control (16) works independently and
should be adjusted clockwise (CW) to the
minimum RF squelch setting at which the
RF level Meter (12) and one of the Diversity
Indicators (8/13) will remain on while your
transmitter is in normal use, up to the
maximum operating range anticipated in use
for your application. However, in areas of
high RF activity, the Mute control may need
to be adjusted counterclockwise (CCW).
If the transmitter is off and the RF Signal
Meter (12) and Diversity Indicators (8/13) are
flickering or stay on continuously, the Mute
level should be adjusted higher level CCW
(counterclockwise for less mute sensitivity
level) to stop the flickering. Be careful not
to adjust a too high CCW setting as this
may reduce the operating range to below
what is needed. A range walk test will help
in selecting the proper level. If the range
is not critical, note that a counterclockwise
(maximum mute) setting will also yield
a quieter mute function, which might be
desired in certain applications. The Mute
level is factory preset at clockwise (CW) for
maximum sensitivity and operating range
(i.e. clockwise (CW) for minimum squelch
level—maximum usable range).
Note: Both receivers’ output will be mixed together
as per the individual receivers’ volume settings
as selected by the up/down volume controls.
If separate signals are required for each instrument
then the XLR outputs must be used, however, note
they are not line level or adjustable. The SUM out
is best utilized for switching between separate
transmitters during performance with only one audio
signal at a time fed to the instrument amplifier.
For balanced output, plug an audio cable with an
XLR connector into the XLR Balanced Mic Out
socket for each receiver and plug the other end into
your mixing board or amplifier inputs accordingly
As when making any connection, make sure
the amplifier or mixing board volume is at the
minimum level before plugging in the receiver
to avoid possible sound system damage.
audio level and Peak leD Indicator
The 2W-1KU receiver has two 5-segment
aF/Peak leDs Displays (5) and each works
independently per receiver. The AF/Peak
LEDs light up sequentially, indicating
the level of the audio signal from the
transmitter. Occasional flickering of the
top (red) Peak LED on loud inputs to the
transmitter is normal. If the Peak LED lights
continuously decrease the input audio level
to the transmitter or overload distortion
may result.
Your 2W-1KU receiver is now operational
and ready to use. Once you have completed
the above steps, proceed to the following
instructions for the HT-1KU handheld or
BT-1KU instrument transmitter.
Note: Only one transmitter can be used with one
receiver. It is not possible to use two transmitters
on the same frequency and mix the output of
these transmitters into one wireless receiver.
However, as this is a two receiver unit, two
transmitters on separate frequencies can be
utilized, one with each receiver.

the display will return to the main menu.
At Power Off the transmitter will store
the last settings entered and re-display
them at the next power on where it can be
reprogrammed to any new Group/Channel
or Volume level at the first time of use or
anytime later. The factory default setting for
Volume -10dB is same for all transmitters.
These settings are optimal for most
applications.

best for most applications.
For normal operation, the transmitter should
have the same Group/Channel as displayed
on the receiver. The default factory setting is
Group 04 (Transmitter 1) and 05 (Transmitter
2), and Channel 00 for all transmitters.
After programming is finished, slide the
battery cover back then turn the Mic Ball (25)
counterclockwise to secure the housing.
The HT-1KU is now ready for use.
Note: If procedure is not done correctly during the

previous programmed channel remains
unchanged.
The IR link is infrared light and thus works best
when this data transfer is accomplished in a
light-shielded or darker environment. It may not
be successful in a brightly lit area. If the transfer
fails, repeat the procedure in a darker location
or somehow shield the link from outside light to
successfully program the transmitter with the

Programming the BT-1KU
to the Selected Channel
The transmitter can be programmed to the
same frequency as selected for the receiver,
either via automatic synchronization using
the IR Sync function or manually on the
transmitter itself.
IR Sync Programming:
Use the wireless IR leD Receptor Sensor (45)
to download pre-programmed channels from
the receiver. Start programming by holding
the IR LED Receptor about 6”-12” from
the receiver’s IR leD Window (1), then press
the IR Sync Button (2) on the receiver to be
used. When short pressing the ASC IR Sync
Button, while the main menu is displayed,
the IR LED will light up red for about three
seconds. This indicates IR transmission is in
progress and IR data is transferring during
this period. Upon successful data transfer
(usually in about three seconds) the IR LED
stops and the transmitter’s backlight will
light up and the transmitter will transmit
a radio signal on the same channel as the
receiver. The Signal Strength and Diversity
Indicators on the receiver’s LCD display will
then light up, indicating that the IR link is
completed.
To change volume input level only, press the
Set button three times to select the volume
input level setting. Use the Up/Down to
change in four steps from 0dB to -30dB
(-30dB for loudest input). The level is preset
at -10dB for LT/HM and 0dB for GT. These
settings are optimal for most applications.

slide the power switch to “ON” to un-mute.
To mute, slide the power switch to “MUTE”
again. Adjust the volume of the receiver per
Connecting Audio Outputs section above.
Note: Avoid acoustic feedback (howling or
screeching) by taking care in selecting PA volume,
transmitter location and speaker placement.
note: If you are using multiple transmitters at
the same location, set up the first transmitter
and leave it ON and keep it 3 ft. away from the
receivers. Then start AUTO-SCAN on the second
receiver. This avoids duplicate selection of the
same channel as already selected for the first
receiver.
The RF Signal meter and the Diversity A/B
indicator on the receiver’s LCD display should
be “On” in normal operation.
Instrument Use (BT-1KU/GT only)
Secure the connection of the GT
(instrument) cable by lining up the slot
of the 3.5mm mini locking Input Jack (40)
connector and turning the ring to securely
lock in. When ready to play, slide the Power

hardwired cord or select up to an added
4-5dB boost by leaving the receiver volume
to maximum for normal use with guitars
and bass guitars. Note this function is best
when using two transmitters for switching
during performance as these is only a single
mixed output from the two receivers. If an
individual output per receiver is desired, use
the XLR Mic Outputs (17), noting that those
are only fixed Mic level outputs.
If you are not satisfied with a channel after
scanning, repeat again anytime for another
free channel.
Operating the BT-1KU
Bodypack Transmitter
During normal operation with the unit
powered on, the transmitter power level
can be changed by sliding the RF Power
Switch (46) to “H” to increase the
transmitted RF power (for longer range) or
to “L” to decrease the RF power (reduced
range). This is a useful feature as the “L”
setting increases battery life and also
optimizes the number of channels that can
be used simultaneously in a given location.
Use this setting for normal use not requiring
maximum operating range. A range walk
test before use will determine which
setting is best for your application.
Note: The audio level should be adjusted on
the instrument as when using a hard-wired cord.
For most applications the transmitter’s Input
Volume Level (29) should be set at 0dB for optimal
performance. Use attenuation levels (-10dB, -20dB,
-30dB) only for higher output instruments, such as
bass guitars with active pickups, and then only if
needed for cleaner sound.
The Power Off/Mute/On Switch (41) has three
positions and functions both as a power
on/off and as an audio mute on/off switch.
After the unit is powered on, slide the
power switch to the “ON” position to un-
mute the audio. With Power Off/Mute/On
switch in either in “MUTE” or ON” position

Cautions and Troubleshooting
To reprogram, you must first find an open
Feedback
channel. To do this, follow the operating
procedure outlined in Selecting the 2W-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 (12) (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 2W-1KU Series systems
simultaneously, repeat this procedure
with every new channel being selected,
with previously tuned systems all on,
both transmitters and receivers.
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.
no or low audio
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 (41) is not in the Mute
position. The receiver’s Unbalanced line
level Out (18) is adjustable so make sure
the Volume (11) is set properly.
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.
The above statement is valid only for use
in the U.S.A.
RF Interference and
Finding Open Channels
Note: More bars in the Received Signal (12) icon
indicate good signal strength in operation with the
transmitter on, but more than 1 bar showing with
the transmitter off also indicates the presence of
likely RF interfering signals at that location. If this
happens, select a different GRP/CH. One bar or
less is ideal for interference-free operation.
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 2W-1KU Receiver: 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.

Miscellaneous Tips
• For optimal operation with external
antennas, low loss RF shielded cable
should be used and the length of the
cable should not exceed 10 ft. (3 m).
• For the best operation, the receiver should
be placed at least 3 ft. (1 m) above the
ground and 3 ft. (1 m) away from a wall or
metal surface. The transmitter should also
be at least 3 ft. (1 m) from the receiver.
Keep antennas away from noise sources
such as motors, automobiles, neon lights,
signal processors, computers, as well as
large metal objects.
• The receiver antennas should be kept
away from any metal surfaces whenever
possible as they can reflect away or
shield the incoming RF signal.
• If the receiver’s volume control is set
too high, it may overdrive the input
of the attached audio mixer, causing
distortion. Conversely, if the output is set
too low, the overall signal-to-noise ratio
of the system may be reduced, causing
noticeable hiss. If such noise occurs,
adjust the output level of the receiver
so that highest sound pressure level
going into the microphone transmitter
causes no input overload in the mixer, but
permits the mixer level control to operate
in the normal range (not too high and
not too low). This provides the optimum
signal-to-noise for the entire system.
• A receiver cannot receive signals from
two or more transmitters simultaneously.
• Turn the transmitter off when it is not
in use. For longest life, remove the
batteries if the unit is not to be used for
a long period as the transmitters draw
a tiny residual current to maintain the
programmed settings, even when turned
off. Also, since batteries installed for a
long time can sometimes corrode and/or
leak, causing damage, it is generally
recommended that batteries be removed
whenever the transmitters are not
being used.
• Before inserting the batteries, ensure that • When using the BT-1KU bodypack for
they are inserted with the correct polarity.
instrument use: Scratchy noises can
sometimes occur when an electric guitar
with dirty pots or connections is used with
a wireless system. Therefore, the supplied
capacitor provides first-order filtering of
the RF signal from the cord into the guitar
and eliminates virtually all scratchy noises.
Should your equipment still produce
scratchy noise, we suggest these steps
to eliminate problems:
• Before operation, confirm that the
receiver and associated transmitter are
tuned to the same frequency group and
channel number.
• After making a receiver channel change,
ensure that the corresponding change is
also made on the matching transmitter.
• Use only brand new alkaline batteries.
Do not use “general purpose” carbon
batteries. When batteries are weak,
replace all the batteries at the same time.
Do not mix new and old batteries.
1) Make sure all guitar volume and tone
pots are clean and all contacts are solid.
This is very important.
2) Solder a 47pF capacitor across the pot
to ground terminal of the guitar’s volume
and tone pots to provide extra filtering.
• Position the receiver so that it has the least
possible obstructions between it and the
transmitter. Line-of-sight is best!
• During operation, the transmitter and the
receiver should be as close as possible for
optimum results but never closer than 3 ft.
(1 m) as that may overload the receiver’s
input circuitry and cause noises.
