MIPRO ACT-82a Wideband Dual-Channel Digital Receiver - Manual (Page 4)

! EIA-standard 19” 1U metal chassis.
! Expanded 120MHz wide bandwidth.
! 24-bit audio quality and digital RF transmission.
! Proprietary 128-bit RC4-derived encryption guarantees secure audio transmission, preventing
unauthorised listening.
! <2.9m latency; T.H.D. is lower than 0.04% at 1KHz.
! Enhanced RF filter and circuitry improve anti-interference characteristics and increase system
compatibility.
! DigitnamicPlus™ technology eliminates compander noise assuring original sound quality.
! Built-in user-defined microphone capsule equalisation (with ten presets) enables audio characteristics
to be modified to suit the performer's individual preference.
! Digital transmission offers better resistance to interference.
! Digital transmission quality is constant, therefore signal-noise ratio does not deteriorate as received
signal becomes weaker with distance.
! Proprietary audio A/D converter provides a true dynamic range of 115dB(A) which eliminates
saturation and distortion at higher frequencies under high SPL input conditions.
! Digital AES/EBU outputs for direct digital connection to digital consoles.
! Wordclock in/thru facility (with indicator) ensures correct synchronisation with other digital
equipment.
! Intuitive and easily accessible user controls, allowing for quick and easy system setup via a single
rotary control.
! Industry-standard AutoScan and ACT™(Automatic Channel Targeting) sync technology for fast, easy,
transmitter setup.
! Optional comprehensive PC-controllable MIPRO RCS2.Net software allows real-time network
adjustments and monitoring of multiple, large-scale systems.

MIPRO'S Proprietary "ACT" Function and Operation
Once ACT button is pressed, it
automatically syncs the selected receiver
frequency to any MIPRO ACT handheld or
bodypack transmitter in the same
frequency band quickly and precisely.
ACT Set-Up
! No manual frequency adjusting needed, unlike traditional transmitters.
! Simple, fast and precise frequency setup without mechanical errors.
! Once the frequency has been set, the data is written to memory in the transmitter.
What is ACT?
ACT Benefits：
! Ensure a receiver channel is set up, the transmitter battery is charged, and the transmitter is
powered ON.
! Press and release the ACT button on the receiver to activate the ACT sync function. Once activated,
the words “ACT” and “Sync” will illuminate.
! Move the ACT handheld or bodypack transmitter IR window to within 30cm (12”) of the IR port on
the receiver. The IR port on the receiver is located behind the “ACT” button itself and is indicated by
a round, dark red dot. The frequency will sync automatically.
! When the frequencies have successfully synchronised between the receiver and transmitter the
illuminated “ACT” and “Sync” will disappear. The RF meter will now illuminate and show full RF
strength.
“ACT” stands for “Automatic Channel Targeting”. MIPRO developed and patented this innovative InfraRed
(IR) technology in 2001. MIPRO was the first manufacturer in the industry to automatically synchronise
the frequency selected on the receiver to any ACT handheld or bodypack transmitter in the same
frequency band.
This ensures that the transmitter frequency now stays with that transmitter. That is, of course, until
a change is required. By performing the “ACT” function again, the frequency can be re-programmed
to another Group/Channel as necessary.
