Congratulations on your purchase. The Nady DKW-1 is the perfect entry level professional wireless, and delivers clear,
transparent audio for a variety of singing and speech applications. Although offered at a breakthrough new low price for a
professional wireless, this system is loaded with features:

• High-band VHF (170-216 MHz) operation for interference-free performance

•

Companding circuitry for a wide dynamic range (no overloading for loud inputs or background hiss during quiet use)

• Full frequency response from 40 –20,000 Hz

• 250 ft. typical, up to 500 ft. line-of-sight operating range

• Choice of transmitters:

• WHT-14 Handheld mic with a powerful neodymium cartridge that delivers unsurpassed audio, low handling
noise and enhanced feedback rejection

• WLT-14 Bodypack for lavalier/lapel headworn mic

• DKW-1receiver with unique vertical space-saving mini portable design and jumbo LED indicators for power ON,
transmitter ON and audio peak. Special added circuitry eliminates transmitter ON/OFF"pop" noise.

OPERATION

A. DKW-1 RECEIVER

1. Plug the AC/DC adapter (provided) into the 12VDC INPUT JACK (3)
on the back of the receiver. Then plug the power supply into an AC
outlet. Slide the POWER SWITCH (1) to the ON position. The
POWER ON LED (6) will now light and the receiver is operational.

2. Rotate and extend ANTENNA (7) to the full vertical position.

3. The 1/4” AUDIO OUTPUT JACK (2) provides a fixed, unbalanced
MIC level audio output for connection to your mixer with the 3 ft.
1/4” to 1/4” cord supplied. As when making any connection, make sure the
mixing board’s volume is at the minimum level before plugging in the
receiver to avoid possible sound system damage.

B. WHT-14 HANDHELD MIC TRANSMITTER

1. Unscrew the BATTERY COMPARTMENT COVER (8) and remove,
exposing the BATTERY HOLDER (11). Insert a fresh 9V BATTERY (9),
observing correct polarity as marked, and screw the cover back on to the
microphone. To ensure proper battery contact, the cover must be screwed
on completely.

2. Turn on the WHT-14 by sliding the OFF/MUTE/ON SWITCH (10)
to the MUTE position (transmitter on, audio muted) or the ON position
(transmitter and audio both on). The BATTERY INDICATOR LED (12)
will give a single quick flash, indicating usable battery strength. In the case of
a dead or low battery, the LED will either not go on at all or will stay on
continuously, indicating that the battery should be replaced with a fresh one.

3. The microphone is now ready to use. The TRANSMITTER SIGNAL
RECEIVED LED (5) on the DKW-1 receiver should now be lit. When ready
to speak, slide the transmitter switch to the ON position and adjust the mixing
board volume level as needed. The AUDIO PEAK LED (4) will flicker on the
receiver with the audio peaks of the microphone input. This is normal. If the
indicator lights continuously, it means the signal is too loud and there is the
possibility of overload distortion. Back off from the microphone until the
indicator only flickers on peaks.

transmitter location and speaker placement so that acoustic feedback (howling
or screeching) will be avoided. See also Section C 3 below.]

Opening Battery Compartment

C. WLT-14 LAVALIER/LAPEL OR HEADWORN MICROPHONE BODYPACK TRANSMITTER

1. Snap open the BATTERY COMPARTMENT (13) and insert a fresh 9V BATTERY (14), observing the correct polarity.
Close the compartment.

2. The WLT-14 is provided with a 3.5mm LOCKING JACK (18) for connecting the microphone. Plug in either the
LAVALIER/LAPEL (19) or the HEADWORN MICROPHONE, as supplied. To secure the connection, turn the metal slip
ring on the plug clockwise to thread it on to the jack. To unplug, reverse the process. Slip the transmit
ter into a pocket or clip on to your clothes. To use the lavalier mic, attach it at chest level. Do not place too close to
the mouth—a distance of about six inches usually works best. To use the headworn mic, place it on the head and
adjust the mic boom so that the mic is about one inch to the side of the front of the mouth. (

headworn mic wire is also the transmit antenna, and rolling up or shortening the wire may reduce the effective
operating range. Extend the wire fully during use, and keep it as straight as possible.)

3. Turn on the WLT-14 by sliding the OFF/MUTE/ON SWITCH (15) to the MUTE position (transmitter on, audio
muted) or the ON position (transmitter and audio both on). The BATTERY INDICATOR LED (16) will give a single
quick flash, indicating usable battery strength. In the case of a dead or low battery, the LED either will not go on at
all or will stay on continuously, indicating that the battery should be replaced with a fresh one.

4. The microphone is now ready to use. The TRANSMITTER SIGNAL RECEIVED LED (5) on the DKW-1 receiver should
now be lit. When ready to speak, slide the transmitter switch to the ON position and adjust the mixing board volume
level as needed.

[Note: Observe care in selecting P.A. volume, transmitter location and speaker placement so that
acoustic feedback (howling and screeching) will be avoided. Please also observe the pickup patterns of the
microphone selected: omnidirectional mics pick up sound equally from all directions and are prone to feedback if
not used carefully. Unidirectional mics are more resistant to feedback, but pick up sound sources best that are
directly in front of the mic. Also, mics that are farther from the sound source, such as lavaliers, require more
acoustic gain and thus are also more prone to feedback than close-source mics such as handheld or headworn mics
that are used close to the mouth.]

5. For optimum performance, an AUDIO INPUT LEVEL CONTROL (17) is provided. Adjust the microphone gain with a

small slot-head screwdriver. Set for maximum possible gain without noticeable distortion on the high level peaks.
Turning the trim control clockwise increases the audio level; turning it counterclockwise decreases the audio level.
Experiment for the best sound for your application. The AUDIO PEAK LED (4) will flicker on the receiver with audio
peaks on the microphone input. This is normal. If the indicator lights continuously, it means the signal is too loud and
there is the possibility of overload distortion. Re-position the microphone farther from the source or adjust the AUDIO
INPUT LEVEL CONTROL (17) until the indicator flickers only on the loudest inputs.
