OPERATIONS


SYSTEM OPERATION
(I)     HANDHELD MICROPHONE SYSTEM 

  1. Set the antennas at an angle 45  from the floor and 90  away from each other to achieve the best RF reception.

  2. Connect the AWR6012U receiver DC input to an AC power source via the supplied AC/DC adaptor.

  3. Connect the AWR6012U receiver audio output to the microphone input of a mixer via the supplied audio cable or any other appropriate cable.  (Note: There are two types of outputs: one unbalanced output and two independent balanced outputs.)

  4. Place one 9V battery into the battery housing of the AWX6030 microphone with the battery polarity oriented as indicated.

  5. Turn on the power of the AWR6012U receiver. The Power On LED light will be turned on.

  6. On the AWX6030, the On/Off switch has three positions: “ON”, “MUTE” and “OFF”. When the On/Off switch is turned to the “MUTE” or directly to the “ON” position, the low battery LED indicator will blink once and then stay off. If the low battery LED indicator stays on, the 9V battery needs to be replaced. When the On/Off switch is set to the “MUTE” or “ON” position, the corresponding channel 1 RF LED light or channel 2 RF LED light on the AWR6012U receiver will be turned on. The corresponding channel 1 AF LED light or channel 2 AF LED light will be on whenever the AWX6030 receives any sound while the On/Off switch is set at the “ON” position.

  7. Adjust the volume control knob on the AWR6012U receiver to have an optimal sound quality.

(II)   LAPEL (LAVALIERE)  MICROPHONE SYSTEM 

  1. Set the antennas at an angle 45  from the floor and 90  away from each other to achieve the best RF reception.

  2. Connect the AWR6012U receiver DC input to an AC power source via the supplied AC/DC adaptor.

  3. Connect the AWR6012U receiver audio output to the microphone input of a mixer via the supplied audio cable or any other appropriate cable.  (Note: There are two outputs: one unbalanced output and one balanced output.)

  4. Place one 9V battery into the battery housing of the AWX6030M transmitter with the battery polarity oriented as indicated. Connect the supplied lapel (lavaliere) microphone to the AWX6030M transmitter.

  5. Turn on the power of the AWR6012U receiver. The Power On LED light will be turned on.

  6. On the AWX6030M, the On/Off switch has three positions: “ON”, “STDBY” and “OFF”. When the On/Off switch is turned to the “STDBY” or directly to the “ON” position, the low battery LED indicator will blink once and then stay off. If the low battery LED indicator stays on, the 9V battery needs to be replaced. When the On/Off switch is set to the “STDBY” or “ON” position, the corresponding channel 1 RF LED light or channel 2 RF LED light on the AWR6012U receiver will be turned on. The corresponding channel 1 AF LED light or channel 2 AF LED light will be on whenever the AWX6030M transmitter receives any sound while the On/Off switch is set at the “ON” position.  The audio level adjustment knob is preset at midpoint. If you need to increase the audio level, use a screwdriver to turn the audio level adjustment knob clockwise. Turn the audio level adjustment knob counter-clockwise to reduce the audio level.

  7. Adjust the volume control knob on the AWR6012U receiver to have an optimal sound quality.

(III)  HEADSET MICROPHONE SYSTEM 

  1. Set the antennas at an angle 45  from the floor and 90  away from each other to achieve the best RF reception.

  2. Connect the AWR6012U receiver DC input to an AC power source via the supplied AC/DC adaptor.

  3. Connect the AWR6012U receiver audio output to the microphone input of a mixer via the supplied audio cable or any other appropriate cable.  (Note: There are two outputs: one unbalanced output and one balanced output.)

  4. Place one 9V battery into the battery housing of the AWX6030H transmitter with the battery polarity oriented as indicated. Connect the supplied headset microphone to the AWX6030H transmitter.

  5. Turn on the power of the AWR6012U receiver. The Power On LED light will be turned on.

  6. On the AWX6030H, the On/Off switch has three positions: “ON”, “STDBY” and “OFF”. When the On/Off switch is turned to the “STDBY” or directly to the “ON” position, the low battery LED indicator will blink once and then stay off. If the low battery LED indicator stays on, the 9V battery needs to be replaced. When the On/Off switch is set to the “STDBY” or “ON” position, the corresponding channel 1 RF LED light or channel 2 RF LED light on the AWR6012U receiver will be turned on. The corresponding channel 1 AF LED light or channel 2 AF LED light will be on whenever the AWX6030H transmitter receives any sound while the On/Off switch is set at the “ON” position. The audio level adjustment knob is preset at midpoint. If you need to increase the audio level, use a screwdriver to turn the audio level adjustment knob clockwise. Turn the audio level adjustment knob counter-clockwise to reduce the audio level.

  7. Adjust the volume control knob on the AWR6012U receiver to have an optimal sound quality.

(IV)      GUITAR OR INSTRUMENT SYSTEM 

  1. Set the antennas at an angle 45  from the floor and 90  away from each other to achieve the best RF reception.

  2. Connect the AWR6012U receiver DC input to an AC power source via the supplied AC/DC adaptor.

  3. Connect the AWR6012U receiver audio output to the guitar amplifier input via the supplied audio cable or any other appropriate cable.  (Note: There are two outputs: one unbalanced output and one balanced output.)

  4. Place one 9V battery into the battery housing of the AWX6030G transmitter with the battery polarity oriented as indicated. Connect the supplied guitar to the AWX6030G transmitter.

  5. Turn on the power of the AWR6012U receiver. The Power On LED light will be turned on.

  6. On the AWX6030G, the On/Off switch has three positions: “ON”, “STDBY” and “OFF”. When the On/Off switch is turned to the “STDBY” or directly to the “ON” position, the low battery LED indicator will blink once and then stay off. If the low battery LED indicator stays on, the 9V battery needs to be replaced. When the On/Off switch is set to the “STDBY” or “ON” position, the corresponding channel 1 RF LED light or channel 2 RF LED light on the AWR6012U receiver will be turned on. The corresponding channel 1 AF LED light or channel 2 AF LED light will be on whenever the AWX6030G transmitter receives any audio signal while the On/Off switch is set at the “ON” position.  The audio level adjustment knob is preset at midpoint. If you need to increase the sound level, use a screwdriver to turn the audio level adjustment knob clockwise. Turn the audio level adjustment knob counter-clockwise to reduce the sound level.

  7. Adjust the volume control knob on the AWR6012U receiver to have an optimal sound quality.

OPERATION NOTES 

  1. The AWX6030, AWX6030M, AWX6030H, or AWX6030G needs to be turned off before changing the 9V battery.

  2. Signal dropout or unexpected noise may be caused by a low battery or by an excessive distance between the transmitter and the receiver.  If you encounter signal dropout or unexpected noise, please check the battery first.  If battery is still fresh, try to readjust the antennas on the AWR6012U receiver.

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

  4. Avoid placing the receiver antennas close to an obstruction or close to any metal surface.

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

  6. If more than one AWM6012U wireless microphone systems are stacked together or placed in a rack, do not let the antennas touch each other or cross each other.

  7. Before the AWM6012U is to be used in a new location, place the AWR6012U receiver at the intended location and walk-through the area with the transmitter to locate any radio frequency blind spot, where a momentary loss of sound or short period of noise may occur whenever the transmitter is moved to this spot.

  8. Do not drop the transmitter on the floor or strike the transmitter with any object.

  9. Always turn off the transmitter and remove the battery if the transmitter is not to be used for a period of time to prevent the transmitter from being damaged by a leaking battery.
