OPERATING INSTRUCTIONS
UHF-16 Receiver
4. Choosing an Operating Frequency
Choose an operating frequency by selecting any of the 16 UHF operating frequencies available in the band
provided, using the UP/DOWN BUTTONS (12). The CHANNEL SELECTED (11d) and OPERATING
FREQUENCY (11f) icons in the LCD DISPLAY
(11d)
(11a)
(11b)
(11c)
(11) indicate the channel and frequency you
have selected. You must also set your
transmitter UP/DOWN BUTTONS (20,25) to
the same channel you choose on the receiver.
(See UH-16 or UB-16 TRANSMITTER
OPERATING INSTRUCTIONS, page 10 & 13
and CHANNEL DISPLAY AND UP/DOWN
BUTTON OPERATION, page 15). For a listing
of the frequencies in each of the 3 available
bands, see page 16.
(11e)
(11f)
5. Mute Adjustment
The receiver has two audio mute circuits.
a. The Tone Squelch™ blocks the audio noise when the channel signaling tones are not present. It helps
avoid interferences from unwanted transmissions. This feature is strongly recommended for situations
where the transmitter is turned on and off during use. Without Tone Squelch™, an unwanted signal may
enter your inactive receiver when your transmitter is switched off. You then risk a pop or disruptive noise
coming from your sound system. This type of interference is eliminated by the Tone Squelch™. The
receiver detects a tone signal coming from your transmitter, which opens the squelch, allowing your
modulated signal to be heard. This feature is selectable and not recommended for applications where the
transmitter will always be on, or for use with instruments.
The Tone Squelch™ mode can be configured with the Up/Down buttons. See CHANNEL DISPLAY AND
UP/DOWN BUTTON OPERATION, page 15.
(Note: If the receiver is configured for Tone Squelch™ mute, the transmitter must also be configured to
send the tones, otherwise the receiver audio will remain muted. The signaling tones are also used to
display the transmitter battery status. If the Tone Squelch™ is defeated, this function will not be
operational.)
b. The Receive Level Mute blocks audio noise when the received signal level is too low, or interfering
transmissions are high.
A MUTE (RF SQUELCH) CONTROL (13) is provided on the front panel. This control should be adjusted
counterclockwise to the minimum position at which there is no audio output signal from the receiver when
your transmitter is not in use. This is the most sensitive setting for your receiver and offers the maximum
operating range. However, in areas of high RF activity, the mute may need to be adjusted. When the
transmitter is off and the receiver’s RECEIVED RF LEVEL METER (11a) icon flickers or displays one or
more segments, and/or white noise (hiss) is heard at the receiver output, the MUTE CONTROL (13) should
be turned clockwise until the noise is muted (squelched). Turning the MUTE CONTROL too far clockwise
will reduce operating range but will yield a quieter mute function. Note that the MUTE CONTROL operates
independent of the RF LEVEL METER so that adjusting the MUTE will not affect any readings at the RF
LEVEL METER.
6. Diversity Operation
During operation only one of the A or B DIVERSITY STATUS ICONS (11e) will be lit, indicating the
receiver’s DigiTru Diversity™ circuitry is selecting antenna input A or B for the best signal. This is normal
and ensures that the received audio will not be interrupted. Sometimes, especially at ranges greater than
75 feet, the squelch circuit will activate in certain locations of the transmitter with respect to the receiver.
Such areas are called “null spots” and indicate that the transmitter is out of range for that given location,
and the user should move closer to the receiver or to another area to re-establish the radio link.

OPERATING INSTRUCTIONS
UHF-16 Receiver
7. Connecting Audio Output
The UHF-16 receiver provides both a fixed mic level BALANCED AUDIO OUTPUT XLR (4) and an
adjustable 1/4” line level LINE OUTPUT JACK (3).
(Note: 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.)
a. Instrument Connection (using the UB-16 transmitter in the “Instrument” setting)
Insert an audio cord with a 1/4" mono phone plug in the LINE OUT JACK (3) on the rear panel of the
receiver. Plug the other end of the cord into an amplifier, effects, or mixing board. Adjust the VOLUME
CONTROL (7) on the UHF-16 receiver clockwise to about 3/4 full, until the volume level is comfortable for
your application. This setting is roughly equivalent to a direct instrument cord connection. Turning the
volume up to MAX will provide 4 dB gain over a cord.
b. Microphone Connection (using the UH-16 handheld microphone transmitter, or the UB-16 transmitter
with either a headworn or lavalier microphone). For microphones, use either the BALANCED MIC OUTPUT
XLR (4) or the 1/4" line level LINE OUT JACK (3).
Plug an XLR connector into the BALANCED XLR OUTPUT (4) jack on the rear of the unit and plug the
other end into your amplifier or mixing board. For your convenience, the XLR output level is preset at the
factory for MIC level and is not adjustable with the receiver VOLUME CONTROL (7).
(Note: Make sure the volume is turned down when making connections.)
To use the 1/4" LINE OUT socket, follow the instructions for the Instrument Connection (above), except
start the receiver VOLUME CONTROL (7) at 1/2 MAX and adjust until the volume level is optimal. If the
volume is set too high, you may overload your mixer or amp.
The UHF-16 receiver is equipped with an AF DISPLAY ICON (11a), which displays up to 4 segments,
depending on the strength of the audio signal from the transmitter. Occasional flickering of the 4th bar
segment of this display on loud inputs to the transmitter is normal. If this segment displays continuously,
decrease the volume to the transmitter or overload distortion may result.
Your UHF-16 receiver is now operational and ready to use. Now that you have completed the above steps,
proceed to instructions for the Nady UHF-16 transmitter included with your system.
(Note: Only one transmitter can be used with one UHF-16 receiver. It is not possible to use two transmitters
on the same frequency and mix the output of these transmitters into one wireless receiver. If you have any
questions, please contact the Nady Systems Customer Service Department. See SERVICE, page 18.)
8. Locking the keyboard
To avoid accidental reconfiguration of the Channel setting or Tone Squelch™, the keyboard can be locked
by holding both the UP and DOWN BUTTONS (12) at the same time for 3 seconds. See the CHANNEL
DISPLAY AND UP/DOWN BUTTON OPERATION, page 15.
9. Simultaneous Multi-Channel Operation
For simultaneous operation of up to 4 –5 channels in a given application and in the same band, use the
procedure outlined above for setting up each channel, ensuring a different frequency for each system.
Operation of a greater number of channels simultaneously can sometimes be more difficult as the channel
combinations must be chosen with care to avoid intermodulation interference between the channels, which
involves more planning than just selecting different frequencies. For additional help and tips to enable more
complicated multi-channel simultaneous operation, contact the Nady Service Department for more
information. (see SERVICE FOR YOUR NADY WIRELESS, page 18).

depending on the strength of the audio signal from the transmitter. Occasional flickering of the 4th bar
segment of this display on loud inputs to the transmitter is normal. If this segment displays continuously,
and/or distortion is heard, decrease the volume to the transmitter. Due to the wide available dynamic range,
generally no adjustment will ever be needed for the transmitter input gain. There is a control under the mic
ball assembly available for rare cases where it’s desirable to make an input gain adjustment. For
instructions on how to access this internal control, please contact the Nady Systems Customer Service
Department. See SERVICE, page 18.
(Note: The microphone element can easily be destroyed by the buildup of salts and minerals from
perspiration and saliva. It is good practice to put a windscreen on the mic element at all times to protect it.)

transmitter must also be configured to send the tones, otherwise the
receiver audio will remain muted. The signaling tones are also used to
display the transmitter battery status.)
7. Locking the Keyboard
To avoid accidental reconfiguration of the Channel setting or Tone
Squelch™, the keyboard can be locked by holding both UP and DOWN
BUTTONS (25) at the same time for 3 seconds. See the CHANNEL
DISPLAY AND UP/DOWN BUTTON OPERATION, page 15.
(33)
8. Microphone and Instrument Operation
The transmitter is now ready to use. The RECEIVED RF LEVEL ICON
(11a), and either the A or B DIVERSITY ICON (11e) on the UHF-16
receiver should now be lit, indicating a received signal from the
transmitter. The receiver TX LED INDICATOR (10) should be on.
a. Instrument Use.
Plug the 1/4" phone plug from the INSTRUMENT (31) cord into the instrument. Verify that the INPUT
SELECTOR SWITCH (23) is in the GT position. When ready to play, slide the audio OFF/STANDBY/ON
SWITCH (28) to the ON position. Adjust the volume of the receiver as per the Audio Output Instrument
Connections section of the preceding UHF-16 receiver instructions.
(Note: The INPUT LEVEL CONTROL (26) is deactivated and not used when the UB-16 is in GT, instrument
mode. Levels should be adjusted with the volume control of your instrument.)
The UHF-16 receiver is equipped with an AF DISPLAY (11a) icon, which displays up to 4 segments,
depending on the strength of the audio signal from the transmitter. Occasional flickering of the 4th bar segment
of this display on loud inputs to the transmitter is normal. If this segment displays continuously, turn down the
instrument volume, or noticeable distortion may result. Experiment and set for maximum possible gain without
audible distortion on the high level peaks. (Note: Turning down the gain or instrument volume too much can
compromise the signal-to-noise and is not recommended.)
(Note: Scratchy noises can sometimes occur when some electric guitars with dirty pots or connections are
used with any wireless system. Therefore, the supplied INSTRUMENT (23) cord has a factory installed
capacitor inside the 1/4" plug. This 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 give you scratchy noises, we
suggest these steps to eliminate them:
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 hot to ground terminals of the guitar’s volume and tone pots to provide
extra filtering.)
13
OPERATING INSTRUCTIONS
UB-16 Bodypack Transmitter
b. Microphone Use (with either a lavalier or headworn microphone)
Secure the connection from the LAVALIER (33) or HEADWORN MIC (34) cord by turning the slip ring on
the plug into the transmitter clockwise to thread it on to the jack. To unplug, reverse the process. To use
the lavalier mic, attach it at chest level. Do not place it 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 boom so that the
mic is about one inch to the side of the front of the mouth.
When ready to speak, verify that the INPUT SELECTOR SWITCH (23) is in either the HM position (for a
connected headworn mic) or the LT position (for a lavalier mic) and slide the OFF/STANDBY/ON SWITCH
(28) to the ON position. Adjust the volume of the receiver as per the Audio Output Microphone
Connection section of the preceeding UHF-16 receiver instructions. For optimum performance, an INPUT
LEVEL CONTROL (26) is provided. Adjust the gain by turning the control with the supplied small slotted
screwdriver. For lavalier mic use, it is recommended that the level be set at about 2/3 maximum. For
headworn mic use, it may be advisable to turn the gain down somewhat, depending on the volume levels
expected. In either application, experiment and set for maximum possible gain without audible distortion
on the high level peaks.
(Note: Turning down the gain too much can compromise the signal-to-noise and is not recommended.)
9. Cautions
a. Feedback
Observe care in selecting P.A. volume, transmitter location and speaker placement so that acoustic
feedback, howling and screeching, will be avoided. Please also note the pickup pattern characteristics 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 models that are used close to the mouth.
b. Microphone Damage
The headset or lavalier microphone element can easily be destroyed by the buildup of salts and minerals
from perspiration and saliva. It is good practice to put a windscreen on the mic element at all times to
protect it.
c. No Audio
If the receiver is configured for Tone Squelch™ mute, the transmitter must also be configured to send the
tones, otherwise the receiver audio will remain muted. See preceding Mute Adjustment section, page 8.
