Nady Systems ENC Duet, Owner'S Manual

1. Snap open the 

BATTERY COMPARTMENT (22)

 and insert a fresh 

9V BATTERY (23)

, 

observing the correct polarity. Close the compartment.

2. The WLT is provided with a 

3.5 mm LOCKING JACK (24) 

for connecting the 

microphone. Plug in either the 

LAVALIER/LAPEL (25)

 or the 

HEADWORN 

MICROPHONE (26)

, 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 operating range. 

Extend the wire fully during use, and keep it as straight as possible.)

3. Turn on the WLT by sliding the 

OFF/STANDBY/ON SWITCH (27)

 to the STANDBY 

position (transmitter on, audio muted) or the ON position (transmitter and audio

both on). The 

BATTERY INDICATOR LED (28)

 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. Most or all of the 

RF DISPLAY LEDs (4)

 on 

the Enc

-

DUET receiver should now be lit, indicating a received signal from the 

transmitter. When ready to speak, slide the transmitter switch to the ON position 

and adjust the volume of the receiver as per the Audio Output Microphone

Connection section of the above Enc

-

DUET receiver instructions. The 

AF LEVEL LED 

DISPLAY (5)

 on the Enc

-

DUET receiver will light up to 5 LEDs (4 green 

and 1 red) for all input signals. Occasional flickering on and off during use of 

the top red LED indicator in this display is normal, however if the red LED stays 

on continuously, it means the signal is too loud and there is the possibility of over-

load distortion. Re-position the microphone farther from the source or adjust the 

AUDIO INPUT LEVEL CONTROL (29)

 until the red LED indicator flickers only on the

loudest inputs. 

(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.) 
(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.)
