SYSTEM OPERATION

1. Fully extend the antennas and set them at an angle perpendicular to the floor to achieve the best RF reception.

2. Connect the AWR6112 receiver AC input to an AC power source via an AC cord..

3. Connect the AWR6112 receiver audio output to the microphone input of a mixer via a cable.  (Note: There are two outputs: one unbalanced mixed output and one balanced mixed output.)

4. Place three rechargeable AA batteries into the battery housing of each of the AWX6112 microphones with the battery polarity oriented as indicated. If the batteries need to be recharged, insert the AWX6112 microphones (with the recharge contacts facing downwards) onto the recharge sockets on the AWR6112 receiver. (Note: Never recharge any battery that is not made to be rechargeable.)  The recharge LED indicators will turn red when the batteries are being recharged. After the batteries are fully charged, the recharge LED indicators will turn yellow.

5. Turn on the power of the AWR6112 receiver. After the power of the AWR6112 is turned on, the fluorescence display will be turned on showing the volume control levels of channel 1 and channel 2.

6. Turn on the On/Off switch on each of the AWX6112 microphones. The low battery LED indicator will blink once and then stay off while the Normal Power LED indicator will then be turned on. If the low battery LED indicator stays on, recharge the rechargeable AA batteries in the AWX6112.

7. Once the AWX6112 microphones are turned on, the audio levels, channel numbers and the corresponding frequencies on the fluorescence display will be on to show the reception statuses.

8. Adjust the volume control knobs to have an optimal sound quality.

 

OPERATION NOTES

1. The brand new rechargeable AA batteries for the handheld microphones need to be charged before use.

2. The AWX6112 handheld microphones need to be turned off before changing the batteries.

3. Signal dropout or unexpected noise may be caused by a low battery or by an excessive distance between the microphone and the receiver.  If you encounter signal dropout or unexpected noise, please check the batteries first.  If batteries are still fresh, try to readjust the antennas on the AWR6112 receiver.

4. Do not drop the microphone on the floor or strike the microphone with any object.

5. Always turn off the microphones and remove the batteries if the microphones are not to be used for a period of time to prevent the microphone from being damaged by a leaking battery.

6. Avoid placing the receiver in a corner to prevent any RF reception deterioration.

7. Try to place the receiver as far away from any digital equipment, including computers and some CD players, as possible.

 

TROUBLESHOOTING

 

 

PROBLEM	POSSIBLE CAUSES	SOLUTIONS
No sound.	Receiver is off.	Turn on receiver.
	Transmitter power switch is off.	Turn on transmitter power switch.
	No battery or bad battery in transmitter.	Insert or replace battery.
	Wrong polarity or faulty battery contact	Correct polarity or battery contact.
	Receiver audio cable is missing or defective.	Connect, repair or replace cable.
Short range or signal dropouts.	Low transmitter battery level.	Replace transmitter batteries.
	Poor antenna reception.	Reposition antenna or receiver.
	Faulty transmitter antenna.	Return transmitter to factory or authorized service station for service.
	Too many obstacles between the receiver and transmitter.	Move the obstacles or move the receiver away from nearby metal objects.
Signal Interference.	Another wireless microphone operating on the same frequency	Use a wireless microphone with different operating frequency.
	Placement too close to a digital signal processor or similar device (CD player, stage lighting, etc.).	1.       Select another operating frequency 2.       Move receiver to another location
	External electromagnetic field source	1.       Select another operating frequency. 2.       Remove source of interference
Distortion.	Low transmitter battery level	Replace transmitter batteries.
	AF Level control on the transmitter set too high, overloading the receiver circuit.	Turn down the AF Level control on the transmitter.
	Volume control on the receiver set too high, overloading the subsequent sound device input.	Turn down the volume control on the receiver.
Momentary loss of sound when transmitter is moved around the performing area.	Radio frequency (RF) blind spots.	Reposition the receiver.  If the momentary loss of sound problem cannot be removed, walk through the performing area and mark “Blind” spots.  Avoid these “Blind” spots during performance.
Low sound level.	Faulty cable connection.	Check cable connection between the receiver and the subsequent sound device.
	Receiver volume control set too low.	Turn up receiver volume control.
Sound levels between two microphones are different.	The receiver volume control and/or  the microphone AF Level control need to be adjusted.	1.       Adjust the transmitter gain control as necessary. 2.       Adjust the receiver volume control as necessary.
