HOW TO CONNECT AUDIO OUTPUT:
There are three rear outputs as shown in the below diagram:
1. MIC 2 BALANCED OUTPUT is balanced audio output using XLR connection.
The grounding of the balanced XLR connection delivers better quality signal and
reduces unwanted noise. This output enables adjusting MIC 2 effects
independently without affecting MIC 1 effects.
2. MIC 1 & MIC 2 MIXED UNBALANCED OUTPUT is unbalanced audio output
using ¼” connection. In effect, two channels are sharing one single signal. To
produce different effects on each microphone, MIC 1 and MIC 2 need their own
independent signals by using two separate XLR connections.
3. MIC 1 BALANCED OUTPUT is balanced audio output using XLR connection.
The grounding of the balanced XLR connection delivers better quality signal and
reduces unwanted noise. This output enables adjusting MIC 1 effects
independently without affecting MIC 2 effects.
UHF WIRELESS SYSTEM DIAGRAM:
We highly recommend using balanced XLR connections if the distance between the
microphone receiver and the amplifier/mixer is more than 10 feet. The grounding of the
balanced XLR connection delivers better quality signal and reduces unwanted noise.

OPERATION
HOW TO SET UP MICROPHONE FREQUENCY
Setting up the microphone is quick and easy. Please follow these simple steps:
STEP 1: Press UP “
▲ ”/DOWN “ ▼ ”on the receiver to select desired frequency.
STEP 2: Open battery compartment on the microphone. Point MIC’s IR PORT
directly at the receiver’s IR PORT that is located on the upper-left-hand corner.
STEP 3: Press SET to initiate the synchronization process. The IR PORT will show
red light if it is sync correctly.
Operation
Each unit is fully tested and qualified by the manufacturer. However, due to the nature of
wireless connection, interference may occur because of local environments and/or radio signals
emitted by other wireless devices within the household.
If MIC 1 or MIC 2 is actively picking up RADIO FREQUENCY (RF) signal when the microphone is
turned off, this is an indication that the frequency is being used by some other active device within
a 200 feet radius. Therefore, selecting a different frequency is highly recommended.

HOW TO ADJUST MICROPHONE VOLUME
Turn VOLUME left to decrease the volume and right to increase the volume on
the receiver.
STEP 1: Press
and hold SET on
the receiver. Do
not release it.
STEP 2: Press UP
“
▲ ”/DOWN “ ▼ ”
on the receiver to
select the desired
squelch level.
STEP 3: Release
both buttons to
set the squelch
level.
SQUELCH (SQ) is used to avoid reproducing noise when the microphone does not
receive enough signals. A value of 0 turns the squelch level off, resulting in more noise and
interference. In contrast, a value of 9 turns the squelch level to the maximum, providing the most
anti-interference ability. However, the drawback of using a higher level of squelch is the reduced
range of the microphone.

TROUBLESHOOTING
CAUTION: Before troubleshooting any symptoms, make sure equipments
are turned OFF.
1. SYMPTOM: NO SOUND COMING FROM MICROPHONE
CAUSE: There is no indication of signal.
REMEDIES:
A. Battery may be low and should be recharged by placing the
microphone onto the CHARGER BASE.
B. Microphone and receiver should be in the same channel to allow
transmitting and receiving signal.
C. Volume is turned to a low level and should be turned to a high but
comfortable volume level.
D. Make sure no wires inside the microphone are loose. If so, reconnect
wires if possible.
E. Make sure the microphone is turned ON; not OFF.
2. SYMPTOM: RECEIVER LCD IS OFF.
CAUSE: Receiver is unpowered.
REMEDIES:
A. AC POWER CORD should be connected properly.
B. Make sure the right AC POWER CORD is being used.
C. Determine whether there is indeed current coming from the power outlet.
3. SYMPTOM: NOISES.
CAUSE: There is interference within your area.
REMEDIES:
A. Make sure user is not standing too close to speakers. Microphone being
too close to speakers will create feedback unless microphone volume is
turned down.
B. Audio cable of poor quality should not be used. Switching to a cable of
higher quality such as a balanced XLR cable can reduce noise.
C. Switch to a model that uses a different set of channels when the above
remedies do not work.
Troubleshooting

4. SYMPTOM: DISTORTION IS INCREASING GRADUALLY.
CAUSE: Battery is running low.
REMEDIES:
A. Recharge battery as soon as possible.
B. Make sure to fully charge battery before use.
5. SYMPTOM: POOR SIGNAL.
CAUSE: Objects can be disrupting communication between receiver and
microphone.
REMEDIES:
A. Make sure no objects are between receiver and microphone, such as
walls and shelves.
B. Make sure microphone usage is not in perimeter of police, fire or radio
stations.
C. Devices that send out radio signals can be disruptive, such as cell
phones, radios, computers, etc.
D. Switch to a model that uses a different set of channels when the above
remedies do not work.
