cable to the socket on the rear panel of the
receiver.
4.1.3 Connect signal cable
Connect UNBALANCED socket in
receiver and MIC INPUT in the amplifier
with the supplied unbalanced audio cable.
The BALANCED socket specializes in
connecting sound stage with the optional
balanced audio cable. Do not use the
Balanced
and
Unbalanced
Sockets
simultaneously! This may cause signal
loss or increased noise.
4.1.4 Adjust the volume in advance
Adjust the volume of the receiver and amplifier to
“
MIN
”
and turn on the receiver, the LCD screen
of the receiver will light on and display as fig.10. Make sure the frequency or the channel of the receiver
are the same to the microphone.
Turn on the microphone, the
“
MUTE
”
will disappear, and the RF
signal will be displayed. At the
same time, the one of the diversity
indicator
“
A
”
or
“
B
”
will be
displayed, if the
“
A
”
appear means the inner receiver A get signal ,while the B works if the
“
B
”
appear.
When you speak to the microphone, the AF signal will be displayed. Moving the microphone, one of the
“
A
”
and
“
B
”
will be selected automatically to appear according to the better signal, this means the
diversity circuit is working to eliminating the blind area. So, this kind of model is fit for more complicated
condition than common model.
4.1.5 Set the volume
Set the VOLUME to get proper volume without feedback.
4.1.6 Change the frequency
To change receive frequency, press the UP key (

from packing box; revolve the two antennae to
the two ANT sockets on the rear panel of the
receiver. Place
the
receiver
near
the
performance area (stage). Point the antennae
upward. Make sure, that the transmitter
(microphone) will never get any closer to the
receiver than 10 ft (3m), optimum separation
is 16 ft (5m). There should always be a direct
line of sight between the microphone and
receiver. Place the receiver at least 5 ft (1.5m)
away from any big metal objects, walls,
scaffolding, ceilings, etc.
4.2.2 Switch on the power
Take out the power adapter, check if the AC voltage stated on the adapter matches the AC
electronic socket in the wall, and then put the adapter into the socket, connecting the power output
cable to the socket on the rear panel of the receiver.
4.2.3 Connect the signal cable
Connect UNBALANCED socket in receiver and MIC INPUT in the amplifier with the supplied
unbalanced audio cable. The BALANCED socket specializes in connecting sound stage with the
optional balanced audio cable. Do not use the Balanced and Unbalanced Sockets simultaneously! This
may cause signal loss or increased noise.
4.2.4 Adjust the volume in advance
Adjust the volume of the receiver and amplifier to
“
MIN
”
and turn on the receiver, the LCD screen
of the receiver will light on and display as fig.12. Make sure the frequency or the channel of the receiver
are the same to the microphones.
Turn on the microphone, the
“
MUTE
”
will disappear, and the
RF signal will be displayed. At the
same time, one of the diversity
indicator
“
A
”
or
“
B
”
will be
displayed, if the
“
A
”
appear means the inner receiver A get signal while the B works if the
“
B
”
appear.
When you speak to the microphone, the AF signal will be displayed. Moving the microphone, the one of
the
“
A
”
and
“
B
”
will be selected automatically to appear according to the better signal, this means the
