Mipro ACT-747-T

Specifications

Features:

• EIA standard 19 “RU robust, heat-dissipating metal housing with perfect shielding against interfering interference.
• UHF-PLL synthesizer with high stability and low side emissions.
• 3rd generation Mipro: Improved RF filter elements and circuits for lower sensitivity to interference signals and more interference-free channels.
• 104 preset channels in 10 groups together with the auto-scan function enable the quick search for interference-free channels.
• The world’s first ACT ™ (Automatic Channel Targeting) offers precise and fast frequency synchronization between the receiver and transmitter.
• True diversity antenna system for best reception quality.
• Dual squelch setting for NoiseLock and pilot tone. Transmitter can be switched on / off at any time without causing disturbing noises.
• The bright color VFD (vacuum fluorescent display), unique in the industry, offers a wide viewing angle on the crystal-clear display of all parameters. Automatic dimming of the display in standby mode.
• All settings can be made intuitively and quickly using a single rotary knob.
• Setting the reception sensitivity via the interference warning display. Higher sensitivity for a wider reception area, lower sensitivity to reduce interference.
• The output signal can be tapped via 3 levels as a single or sum signal. The output level is matched to the sensitivity of the microphone capsule and ensures optimal performance.
• TNC antenna connections with 8V power supply (e.g. for optional boosters)
• PC control software for real-time control and monitoring.
• Internal switching power supply for a stable voltage supply of 100 ~ 240V AC.

Professional analog handheld transmitter:

• Stable PLL circuit. Automatic synchronization with the frequency of the receiver thanks to the patented MIPRO ACT ™ function (Auto Channel Targeting).
• The ACT-72T / ACT-72TC is compatible with the ACT-717/727/747 receivers with a bandwidth of 24 MHz.
• The world’s smallest bodypack transmitter with a robust metal housing made of a special magnesium alloy and battery compartment for operation with two AA batteries (ACT-72T) or a rechargeable lithium battery ACT-72TC).
• After use, simply place the ACT-72TC (battery operation) in the charging station for charging.
• The antenna, power switch and mini XLR input are located on the top of the transmitter.
• The backlit LCD display shows channel, gain, RF output power, mute, battery status as well as lock and error information.
• The innovatively designed battery cover enables quick and easy access to the controls – but at the same time prevents accidental operation.
• External wired mute switch can be connected as a remote control via a 3.5 mm jack socket.
• Input impedance for microphone and guitar (high / low) and input sensitivity of the microphone used can be set (6 levels: + 12dB to -18dB).
• Mini XLR input with secure screw cap for connecting guitars, lavalier and neckband microphones.
• The adjustable belt clip allows the transmitter to be carried in different positions.
