OPERATION INSTRUCTIONS
1.
Turn the volume controls of the receiver and
device in use to a minimum setting before
turning on the microphone transmitter. After
the receivers power switch is set to the on
position, the power switch’s red indicator
illuminates to denote normal power status.
2.
If the SIGNAL LED indicators of the receiver
are illuminated before switching on the
microphone or transmitter, it indicates the
receiver is receiving interference signals. The
more LEDs that illuminate the more severity of
interference. This system has “Pilotone” and
“NoiseLock” dual-squelch features so noise
output will not occur. If multiple channels are
used and both SIGNAL and AUDIO LEDs
illuminate before the transmitter is turned on,
simply adjust the Squelch controls clockwise
until the AUDIO signal indicators extinguish.
(Figure 9). However, by adjusting the squelch
controls it affects the sensitivity level of the
receiver, therefore, shortening the operating
distance and decreasing the stability.
Figure 9
3.
Under normal circumstances, the SIGNAL
indicator lights up when a microphone or
transmitter is turned on near the receiver to
indicate the receiver is ready for normal
operation. Once sounds enter into the
microphone the AUDIO LED indicators will
10
Download from Www.Somanuals.com. All Manuals Search And Download.
illuminate according to the strength of sound
level. If the LEDs do not illuminate or sound is
not present at the output, the system is not
functioning properly and must be checked.
4. RECEIVER AND AMPLIFIER VOLUME ADJUSTMENT:
a.
Unbalanced Audio Output: Switch the level
switch on the rear panel of the receiver to the
left “LOW” Position, then adjust the volume
control to twelve o’clock position. Adjust the
volume control of the amplifier or mixer to an
appropriate sound level. The volume control is
used for fine adjustment of the microphone
sensitivity. When the knob is turned to the
twelve o’clock position the output sensitivity
level of the wireless microphone is the same
as a normal dynamic microphone. Once the
receiver output level is appropriately adjusted,
do not adjust the volume control again. Adjust
the mixer or amplifier volume control if the
sound level needs to increase or decrease.
b.
c.
Balanced Audio Output: Adjust according to
the unbalanced audio output method in the
previous step. (Note: The level switch does
not effect the balanced output.)
To obtain the same sensitivity level when
using a wireless microphone and a wired
microphone with one amplifier or mixer
connect both the receiver output and the wired
output to a “MIC-IN” input jack of the amplifier
or mixer. Adjust the volume controls of the
amplifier or mixer to the same desired level,
then properly fine adjust the receiver volume
control to match the same sensitivity as the
wired microphone.
11

d.
If the receiver output level is adjusted to a
level that is near the maximum input level of
the desired device, it will cause saturation
distortion of the device when the receiver
output level is increased due to a increase in
level by the sound source. Conversely, S/N
ratio will decrease if the receiver volume
control is adjusted too low.
5.
Plug the cable of the mains unit into DC
socket on the receiver’s back panel. Thread
the cable through the cable grip as shown in
the figure below (Figure 10). The cable grip
prevents the connector from being pulled off
by accident.
Fig. 10
5.
Caution
1.
Since the installation of the antenna influences
the operating efficiency of the receiver, the
most important rule is to minimize the distance
as much as possible between the receiving
antenna and the microphone for the best
reception and performance.
2.
The output voltage of the external DC power
supply should not be below 12V, otherwise it
will not work properly. If the voltage is over
15V some components of the receiver will be
damaged due to excessive current draw. Use
a power supply with a 1A minimum rating.

SELECTING A FREQUENCY CHANNEL ON THE RECEIVER
Your local dealer/distributor should be able to advise
you on the best frequency selection for your area and help
with selecting combinations of non interfering frequencies
for multi channel installations. Interference is the most
commonly reported “fault” with wireless microphone
systems; we offer thirty channels from which to choose to
help solve the problem. If you are interfered with, please try
changing the group/channel combination before picking up
the phone. Remember a group/channel combination which
works in one venue will not necessarily work in another
venue but the solution could be no more than the turn of a
dial away. Cross frequency interference is not a fault, it is a
merely a symptom of some form of outside interference or
incorrect frequency selection.
Make your choice of group and channel. (Ensure that
the same combination is selected at the transmitter). If a “-”
symbol is displayed, it means that your choice of switch
position has no connection (only thirty of the possible switch
settings are used so there will be some blanks). A two digit,
numeric display is required for an operational group/channel
combination. There are six group numbers available.
Groups one through four each have six available channels,
one through six. Groups five through six each have three
available channels, one through three. All channels within
the same group are non-interfering (except Group six) when
used in multiple system installations. Move through the
groups and channels until you come to a clear combination.
Please take care when changing the switch settings, the
switches are fragile components. Your local dealer/
distributor will be able to help you with advice as to the
specific frequencies represented by the various group/
channel combinations available to you. This information
may be useful, particularly in a multi use venue.

Insert the 9-volt battery taking care to observe
the correct polarity. If the polarity is correct,
the battery status indicator lamp will flash
briefly. If no flash is observed, then it is likely
the polarity is incorrect or the battery is dead
flat and needs to be replaced.
3.
Replace the grill/ball screen assembly, taking
care to line up the 3 pins and polarizing lug
with the 3 contractor plates. Screw the grill/ball
screen back in to place, taking care not to
force the turns. The turns should be smooth
and easy. If the grill/ball screen assembly
appears to either not engage, or tries to cross
thread, remove it and check for the correct
alignment of the pins.
