The LINK 2TM Plug-In Transmitter

1. Transmitter Set-Up

First, slide open the BATTERY COMPARTMENT DOOR (39) to expose compartment. Insert a fresh 9V ALKALINE BATTERY (41), observing polarity. Close the battery com- partment door.

2.Handheld Microphone Installation

•Step 1 - Rotate the transmitter’s threaded LOCKING RING (33) clockwise toward the XLR CONNECTOR (32) until it stops.

•Step 2 - Hold your mic in one hand and The Link 2 in the other.

•Step 3 - Plug your mic into the XLR CONNECTOR.

•Step 4 - Lock the mic into place with the adjustable threaded LOCKING RING by rotating the ring, counterclockwise, to the top of the transmitter.

•Step 5 - To release the XLR CONNECTOR, turn the threaded LOCKING RING clockwise and press the RELEASE BUTTON (40).

3.Lavalier Microphone Installation

The lavalier microphone you are using must terminate with an XLR connector and conform to the pin assignments shown below. If they do not conform, you must use an appropriate adapter or the lav mic may not work with the Link 2. If you have any questions, please con- tact your Nady dealer or Nady Systems’ Customer Service Department.

Note: the pin assignments on The Link 2’s XLR connector are as shown:

1 Ground

XLR	3		6.5K	6.2K
		2		Phantom Volt. (full 9V battery
Connector	1 2			voltage) switchable
Top View
		3		Mic
				Input

Note: Select phantom power, as needed, with the PHANTOM POWER ON/OFF SWITCH (38)

4. Microphone Operation

a. Turn on The Link 2 by sliding the ON/STANDBY/OFF SWITCH (37) to the STANDBY position (transmitter on, audio muted) or the ON position (transmitter and audio both on). The LOW BATTERY INDICATOR LED (36) will give a single quick flash, indicating usable battery strength. In case of dead or low battery, the indicator will either not go on at all or stay on continuously, indicating a battery voltage below 7V. If this occurs, replace with a fresh 9V battery. Remember to turn the transmitter off when not in use.

b. The Link 2 is now ready to use. The AF DISPLAY LEDs (9) on the 401 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 401 receiver instructions. The AF LEVEL LED DISPLAY (9) on the 401 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 overload distortion. Re-position the microphone farther from the source or adjust the Link 2 transmitter gain with the VOLUME LO/HI GAIN SWITCH (35). Set for the maximum possible level without noticeable distortion on the high level peaks. Set the GAIN SWITCH to LO to decrease the audio level, and set the GAIN SWITCH to HI to increase the audio level. The red LED indicator should flicker 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.)
