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 no adjustments besides audio volume are
required.
• 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 for the desired audio
level.
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.

OPERATING INSTRUCTIONS FOR THE NADY WA 120
Powering the WA 120
• External Adapter
Plug the external AC adapter provided into the Power input jack (14)
on the back of the receiver. Then plug the AC adapter into a standard
115VAC outlet. 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. Plug the RB-120 into the Battery Power/Recharge
jack (17) while the WA 120 is connected to AC power with the provided
AC adapter. If the Battery charging LED (20) 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 charg-
ing LED indicator (20) 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 Battery Power/Recharge jack
(17). The RB-120 can be easily stored in the Storage compartment (12)
while in use or transporting.
(Note: Connecting the AC adapter will automatically disconnect the inter-
nal battery power.)
• (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.)
