OPERATING INSTRUCTIONS FOR THE NADY WA-120
Powering the WA-120
• External Adapter
Plug the external provided AC/DC Adaptor into the External DC input
jack (14) socket. Then plug the AC/DC adapter plug into a standard
115VAC or 240VAC outlet (The AC adapter will detect the line voltage
automatically). Turn on the unit using the Power switch (2).
(Note: To avoid damaging your unit, use only the provided AC adapter
connected to the power input jack.)
• RB-120
The WA-120 can be powered internally using the optional RB-120 re-
chargeable battery. Observe the RB-120 battery positive (+) and nega-
tive (-) polarities when installing it into the Optional RB-120 recharge-
able battery slot (11) while the WA-120 is connected to AC power with
the provided AC adapter. If the Battery charging LED (16) turns red,
the RB-120 is not fully charged and should be allowed to charge while
the WA-120 is powered by the AC adapter. (Note: Turning off the WA-
120 Power switch (2) will allow the RB-120 to recharge more quickly.)
If the Battery charging LED indicator (16) lights green, the RB-120 is
fully charged and ready to power the WA-120 alone. Shut off the Power
switch (2) and disconnect the AC adapter. Turn the unit back “ON” and
the RB-120 will power the unit while still connected to the optional RB-
120 rechargeable compartment (11). The RB-120 can be easily stored in
the Storage compartment (11) while in use or transporting.
(Note: Connecting the AC adapter will automatically charge the internal
RB-120 battery power.)
(Note: Connecting the AC adapter will automatically disconnect the inter-
nal “D” cell batteries. The WA-120 does not recharge “D” cell batteries.)
• (8x) “D” Cell Batteries
The WA-120 can also be powered internally with (8x) ”D” cell batteries.
Insert the batteries while observing the correct polarity as marked. For
longest operation use only alkaline or rechargeable batteries. Replace
the batteries when the output volume drops or the range of the wireless
decreases.
(Note: The WA-120 does not recharge “D” cell batteries.)

Attention:
1. If feedback (howling sound) occurs, try first turning down the
treble control (8). If feedback still is present, try turning down the
volume (7) or repositioning the WA-120 with respect to the wired
or wireless mic being used.
2. Extend the antenna (1) fully whenever using the wireless micro-
phone to ensure optimum performance and maximum range.
Wiring Illustration
Then MIC input (3) can be used to connect a hard wire MIC.
The REC OUT (9) can be connected to a recording device or to the input
jack of a power amplifier to further amplify and enlarge the audio power.
For stereo to mono conversion of the signals, wire the connecting cord
as per the the following illustration:

Stand Mounting the WA-120
The WA-120 can be mounted on
the optional MST-4B aluminum
tripod stand for convenient place-
ment in a higher position. Contact
your dealer or the Nady service
department. (See Page 12)

WA-120 WIRELESS MICROPHONE RECEIVER OPERATION
The WA-120 contains a built-in high quality quartz-locked, fixed
frequency VHF wireless receiver precisely matched to the Nady WHT
or WLT transmitter supplied; therefore generally no adjustments
besides audio volume are required. In high RF activity environment, the
MUTE (16) also needs adjusting to eliminate interference.
• After the amplifier has been turned on by the main Power switch
(2), turn the wireless receiver’s MIC/TS Volume control (7) slightly
clockwise.
• Switch on the wireless microphone and the RF receiving indicator (6)
will light up indicating normal reception.
• Adjust the MIC/TS Volume control (7) clockwise (CW) for the desired
audio level.
• The MUTE control (16) affects the usable distance. Turn CCW for
maximum range or CW for minimum range, which also reduces the
chance of RF interference and resulting audio noise at the limit of
the operating range or when transmitter is off. A range walk test will
determine the required setting.
Note: If using more than one wireless microphone (handheld and/
or bodypack) on the same frequency, switch only one on at a time.
Microphones on the same frequency will interfere with each other.
However, one wireless microphone can be used with two or more
WA-120 wireless amplifiers with the same frequency simultaneously to
increase the overall sound level.

WHT HANDHELD MICROPHONE TRANSMITTER
The Nady WHT is a sleek tapered microphone with these special
features:
• Features the Nady DM -10D unidirectional neodymium dynamic
cartridge for optimum true sound, maximum feedback rejection and
minimal handling noise
• OFF/STANDBY/ON switch allows convenient audio muting with the
transmitter “ON”
• Low battery LED indicator flashes once for unit “ON”; lights steady for
low battery alert
Transmitter Set-up and Operation
• Unscrew the battery compartment cover end cap (1) and remove,
exposing the battery compartment. Insert a fresh 9V battery, observing
polarity. Re-attach the battery cover.
• Turn on the microphone power switch (2) on the handle of the
microphone. The battery indicator LED (3) will give a single quick
flash, indicating usable battery strength. In the case of a dead or
low battery, the indicator will either not go on at all or will stay on
continuously, indicating a need to replace the battery. To preserve
battery life, turn the transmitter off when not in use.
• The RF ON indicator on the WA-120 should now be lit.
• Adjust the volume of the WA-120 to the desired level.
WLT LAVALIER/ HEADMIC BODYPACK TRANSMITTER
The Nady WLT is a rugged compact bodypack designed for use with
lavalier or headworn mics, and includes these special features:
• OFF/STANDBY/ON switch allows convenient audio muting with the
transmitter “ON”
• Low battery LED indicator flashes once for unit “ON”; lights steady for
low battery alert
• Locking 3.5mm mini-jack provides secure connection for removable
microphones
• Easily accessible input level adjust control for optimum sound
• Operates on 9V batteries for economical and long life operation.

Transmitter Set-up and Operation
• Snap open the battery compartment (1) and insert a fresh 9V battery
(2), observing the correct polarity. Close the compartment.
• The WLT is provided with a 3.5 mm locking jack (3) for connecting
themicrophone. Plug in either the Lavalier/Lapel (4) or the Headworn
microphone (5), 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 transmitter 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.
(Note: The lavalier or headworn mic wire is also the transmit antenna,
and rolling up or shortening the wire may reduce the effective operat-
ing range. Extend the wire fully during use, and keep it as straight as
possible.)
• Turn on the WLT by sliding the OFF/STANDBY/ON SWITCH (6) to the
STANDBY position (transmitter on, audio muted) or the ON position
(transmitter and audio both on). The battery indicator LED (7) 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.
• The RF ON light on the WA-120 should now be lit.
• Re-position the microphone farther from the source or adjust the audio
input level control (8) if the monitored volume is to loud or distorted
after adjusting the receiver.
• Adjust the volume control of the WA-120 to a comfortable listening level
as desired.
[Note: Observe care in selecting volume, transmitter location and
speaker placement so that acoustic feedback (howling and screeching)
will be avoided. Please also observe the pickup patterns of the micro-
phone 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.]
(Note: Microphone elements 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.)
