Profile

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/ACT-30Hr are the most evolved
design model for built-in antenna transmitters
nowadays.

Key Features

! The microphone capsule is connected to the transmitter

PCB and then screwed onto the housing to prevent the
potential malfunction caused by improper contact.

! Modularized PCB and microphone capsule can be easily

detached and assembled. Optional premium microphone
capsule modules are available.

! ACT-30H is constructed of sturdy plastic housing to

enhance the transmission efficiency. Special coated
treatment prevents from handling noise and paint
stripping.

prevent the malfunction when knocked. Multi-color rings
for easy channel identification.

! LCD on the housing displays working group, channel,

battery level and error codes.

! High-efficiency low spurious emissions UHF PLL

synthesized RF technology.

! An interference-free working channel can be synchronized

quickly and precisely by MIPRO's proprietary ACT function.

! MIPRO vocal condenser microphone capsule exhibits high

fidelity, wide dynamic range, fast transient responses, low
feedback howling, accurate sound image characteristics,
transparent sound quality and extremely low handling
noise.

! Proprietary high dynamic range modulation circuitry

sustains a maximum SPL of 140dB so performers can be
confident it won't distort when sing loudly.

! Optional MU-89b true condenser microphone capsule is

ideal for natural sound reproduction.

! Built-in volume buttons in ACT-30Hr handheld transmitter

enable volume loudness can be adjusted wirelessly for
MIPRO MA-708 & MA-808 portable PA systems.
