MIPRO ACT-515 Single-Channel True Diversity Receiver - Manual (Page 4)

Key Features and Benefits
! ACT-515/ACT-515B is a EIA standard 19” 1/2-unit true diversity receiver.
! ACT-515T/ACT-514BT is composed of two and housed in a 19”
1U receiver.
! Receiver provides bias voltage for MIPRO antenna systems to enhance reception
range and signal stability.
! Advanced true diversity technology for best reception quality.
! Dual "PiloTone & NoiseLock" circuits minimize interference.
! Backlit LCD displays group, channel, frequency RF & audio strength, A/B antenna,
transmitter battery status, interference warning indicator & panel lock.
! Easy parameters set up with SET, UP, DOWN & ACT operational buttons.
! Backlit LCD is lit in green when signal is received or button pressed. Backlit LCD is
lit in red when no signal or button pressed. Easy to identify working mode (green)
and standby mode (red) during performance.
! Balanced XLR / unbalanced 1/4 " audio output jack, output level switch and DC
input are on the rear panel.
! UHF PLL-synthesized technology for enhanced RF stability, lowered spurious
emissions and increased frequency agility.
! One-touch Autoscan for a clear, interference-free channel.
! Industry's first ACT syncs automatically and quickly a working channel.
! Adjustable 'SQ' for higher sensitivity to increase receiving distance or lower
sensitivity to reduce interference.
! Adjust SQ when Interference warning indicator is lit for ideal sensitivity level.
! Robust metal transmitter housings with patented mechanical design and high
efficiency circuits.
ACT-515/ACT-515B
What is ACT?
'ACT' stands for 'Automatic Channel Targeting'. MIPRO developed and patented this
innovative infrared (IR) sync technology in 2001. MIPRO was the first manufacturer in
the industry to automatically synchronize the frequency selected on the receiver to any
ACT handheld or bodypack transmitter on the same frequency band.
ACT Benefits:
No manual frequency adjusting needed, unlike traditional transmitters.
Simple, fast and precise frequency set-up without mechanical errors.
Once the frequency has been set, the data is stored in memory, meaning that the
frequency is set until it is changed by performing the 'ACT' function again, even
after powering off.
ACT Set-Up:
Ensure a receiver channel is set-up and transmitter batteries are fresh, installed
correctly and powered-on.
Press the 'ACT' button on the receiver to activate the ACT syncing function. Once
activated, the group/channel and working frequency start blinking.
Bring ACT handheld or bodypack transmitter within 30cm (12”) of the IR port on the
receiver. The IR port is located between the 'ACT' and “▼” buttons and indicated by
a round-shaped red color spot. The frequency will sync automatically.
When the frequencies are synchronized successfully between the receiver and
transmitter, the RF meter cursor and working frequency stop blinking and the
indicators in the RF meter are lit.
