5. Connecting the Audio Output
The Encore DUET receiver provides both a fixed mic level BALANCED AUDIO OUT- PUT XLR (14) for each channel and an adjustable line level A + B UNBALANCED AUDIO OUTPUT 1/4" JACK (13) which provides a mixed (summed) Ch A plus Ch B
output signal. The mixed level from the A + B UNBALANCED OUTPUT is controlled by the rear panel VOLUME CONTROLS (6) for each channel. (Note: As when mak- ing 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. Also make sure that the phantom power on the input of the mixer is turned OFF before making connection to the receiver.)
a.Instrument Connection (using the WGT instrument transmitter) Insert an audio cord with a 1/4" mono phone plug in the A + B UNBALANCED OUTPUT JACK (13) on the rear panel of the receiver. Plug the other end of the cord into an amplifier, effects, or mixing board. Adjust the appropriate VOLUME CONTROL (6) for the channel being used on the Encore DUET receiver clockwise to about 3/4 rotation, until the mixed volume level is comfortable for your application. This setting is roughly equivalent to a direct instrument cord connection. Turning the volume up to maximum will provide 4dB gain over a cord. (Note: Since this a mixed output of Ch A & Ch B, both channels with be processed simultaneously by the amplifier and/or effects connected to, which may not be appropriate for your application.
b.Microphone Connection (using the WLT transmitter with either a headset or lavalier microphone or the WHT handheld microphone transmitter)
For microphone use, either the BALANCED MIC AUDIO OUTPUT XLRs (14) or the 1/4" line level A + B UNBALANCED OUTPUT (13) can be used. The XLR output is set at a
For your convenience, the XLR output levels are preset at the factory and are not adjustable with the receiver volume controls. To use the 1/4" A + B UNBALANCED OUTPUT JACK (13), follow the instructions for the Instrument Connection(above), except start with the receiver volume at 1/2 MAX and adjust the volume control for each channel until the mixed Ch A & Ch B volume level is optimal. If the volume controls are set too high, you may overload your mixer or amp.
4. Microphone Operation
a.Turn on the Link 2 by sliding the ON/STANDBY/OFF SWITCH (41) to the STANDBY position (transmitter on, audio muted) or the ON position (transmitter and audio both on). The LOW BATTERY INDICATOR LED (40) 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 bat- tery voltage below 7V. If this occurs, replace with fresh 9V battery. Remember to turn the transmitter off when not in use.
b.The Link 2 is now ready to use. Most or all of the RF DISPLAY LEDs (4) on that channel of the Encore DUET receiver should now be lit, indicating a received signal from that transmitter. When ready to speak, slide the transmitter switch to the ON position and adjust the volume of that channel of the receiver as per the Audio Output Microphone Connection section of the above Encore DUET receiver instructions. The appropriate AF LEVEL LED DISPLAY (5) on the Encore 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 overload distortion.
(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 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
(Note: Microphone elements can easily be destroyed by the buildup of salts and minerals from perspiration and saliva. It is good practice to put
