and audio quality features that allow you to really enjoy the freedom of wireless without
any of the problems.
Engineered For Dependable UHF Systems
As all the other Audio2000'S®
wireless products, the AWM6074U system has been engineered to be dependable UHF system with a wide audio
frequency range, high S/N ratio, and outstanding performance equal to that of any
professional wireless systems costing much more. This is achieved through strict
component selection and high quality circuit design. A delicately designed silence
circuit eliminates static noise when the transmitters are either turned off or out of
transmission range. An auto mute circuit is incorporated in these systems to
effectively eliminate the popping noise when the switch is turned on or off.
System Designed For Accessibility
The AWM6074U system has been
designed and manufactured to be dependable, problem free, versatile and easy to
use. The AWM6074U system is
intended to be readily accessible to everyone with exceptional performance at a preferred
and affordable price.

OPERATIONS
SYSTEM OPERATION
(I) HANDHELD
MICROPHONE SYSTEM
-
-
-
-
Place one 9V battery into the battery
housing of the AWX6070 microphone with the battery polarity oriented as
indicated.
-
Turn on the power of the AWR6074U
receiver. The Power On LED light will be turned on.
-
On the AWX6070, 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 AWR6074U receiver will
be turned on. The corresponding channel 1 AF LED light or channel 2 AF
LED light will be on whenever the AWX6070 receives any sound while the
On/Off switch is set at the “ON” position.
-
Adjust the volume control knob on the
AWR6074U receiver to have an optimal sound quality.

-
-
Place one 9V battery into the battery
housing of the AWX6070M transmitter with the battery polarity oriented
as indicated. Connect the supplied lapel (lavaliere) microphone to the
AWX6070M transmitter.
-
Turn on the power of the AWR6074U
receiver. The Power On LED light will be turned on.
-
On the AWX6070M, 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 AWR6074U receiver will
be turned on. The corresponding channel 1 AF LED light or channel 2 AF
LED light will be on whenever the AWX6070M 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.
-
Adjust the volume control knob on the
AWR6074U receiver to have an optimal sound quality.

Place one 9V battery into the battery
housing of the AWX6070H transmitter with the battery polarity oriented
as indicated. Connect the supplied headset microphone to the AWX6070H
transmitter.
-
Turn on the power of the AWR6074U
receiver. The Power On LED light will be turned on.

OPERATION NOTES
-
The AWX6070, AWX6070M,
or AWX6070H needs to be turned off before changing the 9V battery.
-
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 AWR6074U receiver.
-
Avoid placing the receiver in a corner
to prevent any RF reception deterioration.
-
Avoid placing the receiver antennas
close to an obstruction or close to any metal surface.
-
Try to place the receiver as far away
from any digital equipment, including computers and some CD players, as
possible.
-
If more than one AWM6074U wireless
microphone systems are stacked together or placed in a rack, do not let
the antennas touch each other or cross each other.
-
Before the AWM6074U is to be used in a
new location, place the AWR6074U 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.
-
Do not drop the transmitter on the floor
or strike the transmitter with any object.
-
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.
