SYSTEM OPERATION
- Take the antennas from the shipping box and connect the
antennas to the F connectors on the
rear panel of the AWR6122U receiver. Set the
antennas at an angle 45 from the floor and 90 away from each other to
achieve the best RF reception.
|
- Connect the AWR6122U receiver DC input to an AC power
source via the supplied AC/DC adaptor.
|
-
If needed, adjust
the squelch control of each channel to overcome any excessive external interference signal
or noise that exists when the transmitter is turned off. If the external interference
signal or noise exists when the transmitter is off, adjust the squelch control knob slowly
until the unwanted interference signal or noise is muted. (Note: Setting the squelch too
high will reduce the range of this wireless system.)
|
- Connect the AWR6122U receiver audio outputs to the
microphone inputs of a mixer via phone plug cables.
(Note: There are three outputs: one unbalanced mixed output, one balanced
channel A output, and one balanced channel B output.)
|
- If the AWX6120 handheld microphones are to be used in
the wireless system, place two rechargeable AA batteries into the battery housing of each
AWX6120 microphone with the battery polarity oriented as indicated. If the batteries need
to be recharged, set the AWX6120 microphones (with the recharge contacts facing downwards)
onto the recharge sockets on the AWR6122U receiver. (Note: Never recharge any battery that
is not made to be rechargeable.) The
orange recharge LED indicators will be on when the batteries are being recharged. After
the batteries are fully charged, the orange recharge LED indicators will turn
greenf.
|
- Turn on the power of the AWR6122U receiver.
|
- Turn on the On/Off switch on each of the AWX6120 microphones.
The low battery LED indicator will blink once and then stay off. If the low battery LED
indicator stays on, recharge the rechargeable AA batteries in the AWX6120 microphone.
|
- Once the AWX6120 handheld microphones are turned on, the RF indicators on the receiver will be on to
indicate a proper reception.
|
OPERATION NOTES
- The AWX6120 microphone is equipped with a microphone
sensitivity adjustor (Mic. Adj.). Turn the
Mic. Adj. Knob clockwise to increase the microphone input sensitivity. Turn the Mic. Adj.
Knob counter-clockwise to reduce the microphone input sensitivity.
|
- The brand new rechargeable AA batteries for the handheld
microphones need to be charged before use.
|
- The AWX6120 handheld microphone needs to be turned off before changing the batteries or battery.
|
- The AC/DC adapter used for the AWR6122U has a DC output
of 12-18V, tip positive.
|
- 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 AWR6122U receiver.
|
- Do not drop the microphone on the floor or strike the
microphone with any object.
|
- Always turn off the microphone and remove the batteries
if the microphone is not to be used for a period of time to prevent the microphone from
being damaged by a leaking battery.
|
- Avoid placing the receiver in a corner to prevent any RF
reception deterioration.
|
- Try to place the receiver as far away from any digital
equipment, including computers and some CD players, as possible.
