How to Set-up Interference-free
Compatible Systems for ACT-82a?
-
To set up multi-channel operation, the user must select
factory preset channels within the same group.
-
A combination of preset channels under different groups can
result in possible interference.
-
If one of the preset channels within the same group
experiences interference, try to change to another preset
channel. If interference-free channels can’t be found, it is
highly recommended to change to another group. If
interference persists in all groups, changing to another
frequency band may be recommended.
-
For example, when setting with 5D band / Group 1 / Channels
1,2,3,4, and Channel 3 experiences interference, you have to
change to Channel 5 or another one in Group 1. If any preset
channel in Group 1 still experiences interference, you have
to change to Group 2 or another group. If interference
persists in all groups, you have to change 5D to 6D.
-
In Group 1~10, each group has 24 factory preset
interference-free channels. 1 meters minimum safe distance
is needed between the transmitters and the receivers for
operation. In Group 11~16, each group has 32 factory preset
interference-free channels. 3 meters minimum safe distance
is needed between the transmitters and the receivers for
operation.
-
For less than 24 interference-free channels, MIPRO
recommends in setting up channels from Group 1~10 to ensure
the optimal performance.
-
If more than 32 interference-free channels need to be used
in the same band, but not required for long-distance
reception, then setting up channels from Group 11~16 is
recommended. Transmitters need to be set in "low power" mode
and keep 3 meters minimum safe distance with receivers.
NOTE: The factory preset interference-free channels are
designed for MIPRO ACT-82a receivers only. Do not mix and use simultaneously with wireless microphone
systems from other brands.

-
Expanded 120MHz bandwidth
for increased preset compatible systems.
-
24-bit audio quality and true digital RF
transmission.
-
Proprietary 128-bit encryption guarantees
secure audio transmission, preventing unauthorised
listening.
-
Second generation DSP technology enhances
signal stability and reduces the risk of signal dropouts
during interferences.
-
DigitnamicPlus™ technology eliminates
compander noise assuring the original sound quality.
-
Built-in SmartEQ™ preset and user-defined
microphone capsule equalisation for faithful reproduction to
suit artist's preferences.
-
Digital transmission offers better
resistance to interference.
-
Digital transmission quality is constant,
therefore S/N ratio will not deteriorate as received signal
becomes weaker with distance.
-
Proprietary Audio A/D Converter provides
a true dynamic range of 115dBA to eliminate saturation or
distortion at higher frequencies under high SPL input
conditions.
-
Wordclock in/out facility with activity
indicator ensures correct synchronisation with other digital
equipment.
-
Full-colour VFD (vacuum fluorescent
display) can easily be viewed at distance, at any angle and
in day/night environments.
-
All controls are intuitive and easily
accessible, allowing for quick and easy system setup via a
single rotary controller.
-
Features MIPRO’s patented industry
standard AutoScan and ACT (Automatic Channel Targeting)
technology for easy, fast channel setup.
-
Receiver provides bias voltage for MIPRO
antenna booster systems.
-
Optional MIPRO RCS2.Net software allows
real-time network adjustments and monitoring of multiple,
large scale systems.
-
Ideal for studio, stage and music
performances as well as military, courtroom, conference,
boardroom and broadcast applications ~ anywhere audio
security and accurate, distortion-free reproduction of the
full sound spectrum are required.
