Performance
There are two types of antenna design for the
handheld transmitter microphones “built-in” and
“external”. The “built-in” design is normally
incorporate upper side of PCB in the housing and
the microphone capsule module as transmitting
antenna. The advantages are to avoid the antenna
breakage due to external design, inconvenience and
able to shorten the microphone housing design.
However, its drawbacks are poor transmission
efficiency especially when replacing microphone
capsules, unstable and deteriorated transmission
efficiency if it is gripped over the antenna area. The
“external” design enhances transmission efficiency
and stability, however, it causes inconvenience and
it may be damaged by accidental crashing.
MIPRO's patented design provides an ideal solution.
The antenna is integrated in the battery holder at
the bottom side of the housing, so it successfully
combines the advantages of both “built-in” and
“external” design.
The matched antenna and transmitter circuit
enhance transmission efficiency and stability
regardless capsules and battery replacement, or
change of grip positions and housing materials.
Microphone capsule, audio modulation, RF output
and antenna transmission constitute the perfect
straight-line layout of the transmitter PCB so that it
can achieve the best transmission quality and
efficiency. ACT-30H/30Hr are the most evolved
design model for built-in antenna transmitters
nowadays.

Top Grille: Protects detachable microphone
capsule module and internal foam prevents
breathing, wind and POP noises.
LCD Screen: Displays group, channel, battery
status and error codes.
Remote Volume Control Buttons: Press
to
decrease or
to increase volume wirelessly.
Power On/Off Switch: Slide the power switch
to the “ON” position for use or to the “OFF”
position when not in use.
! An interference-free working channel can be
synchronized quickly and precisely by MIPRO's
proprietary ACT function.

ACT Infrared (IR) Port: Receives signals from
receiver to synchronize frequencies.
1. Gently twist the microphone housing in a
counter-clockwise direction
2. Remove the old batteries from the battery
compartment, if any are installed.
3. Insert two new AA alkaline batteries in the
battery compartment with correct polarity
orientation.

Operating instructions
LCD Screen
1. LCD screen on the transmitter and the RF
level/indicator shown on the receiver will be lit
when the microphone is turned-on, denoting
normal status. A blank LCD screen maybe due to
an incorrect battery polarity orientation.
GROUP CHANNEL BAT
ERR
!ERR Message: When “ERR” appears in the
display it indicates that an operational error has
occurred. Please refer to the following codes to
diagnose which error you are experiencing.
2. The audio level or indicator show on the receiver
will be lit when there is audio line or microphone
input from the transmitter.
ERR no01
EEPROM is not being programmed or
internal data error.
ERR no02
For testing only.
ERR no03
The frequency you want to program is
above the switching bandwidth of the
transmitter. Use a receiver with an
appropriate frequency group. (At this time
the microphone is still operating and the
frequency remains unchanged. To clear the
displayed "ERR" message, switch the
handheld transmitter off and on again.)
ERR no04
The frequency you want to program is
below the switching bandwidth of the
transmitter. Use a receiver with an
appropriate frequency group. (At this time
the microphone is still operating and the
frequency remains unchanged. To clear the
displayed “ERR” message, switch the
handheld transmitter off and on again.)
Caution
Remove the batteries if unused for a long period of
time to prevent battery leakage, corrosion and
causes damage to electronics.
!“Group” & “Channel” : When both the group
and channel numbers are displayed, it means that
you are using the pre-programmed frequency of
the receiver.
!“Channel” Only : If “Channel” only is displayed,
it means that you are using a frequency which is
not pre-programmed.

General tips for improving system
Performance
1. Performer should avoid holding the microphone over or
near the antenna section as this will deteriorate
transmission efficiency. Severe deterioration if performer
directly covers up the antenna section with both hands.
100%
80%
40%
10%
0%
Indicates the power remaining in the transmitter
battery. When the battery has less than 10% power
remaining it must be replaced or recharged. If an
under voltage condition continues, the LCD will show
“Poff” and the system will shut down to prevent
being overly discharged.
“Poff” - Power Off :
2. Many performers tend to hold the microphone by the
top grille. Unfortunately, this position seriously degrades
both the sound quality and directionality of a
microphone. Even the most expensive microphones will
have its original sound quality compromised by this
method. Grabbing a microphone by the grille will isolate
the capsule's acoustic resonance circuit and or change
the capsule resonator's frequency. This results in an
inferior performance in both frequency response and the
separation of directionality. In addition, a palm's soundfocusing effect will tend to strengthen resonances in
certain frequencies and can cause unwanted echo.
3. A proper technique is required for using directional
microphones because the distance between the
microphone and your mouth has a significant impact on
sensitivity and performance. There is an inverse
relationship between microphone sensitivity and the
distance from the mouth to the microphone.
Consequently, performers with a ''weaker'' sound level
cannot expect to hold the microphone too far away from
their mouth and compensate by turning up the amplifier
volume to increase the sound level as this can easily
cause echo or feedback. In contrast, performers with a
''louder'' sound level should not hold the microphone too
close as this can easily result in distortion by causing
the amplifier system to be overloaded.
When the power switch is turned off, the LCD will
show “Poff” (for Power Off) first and then the
system will shut down and no further messages will
be displayed.
