Description
Analogue Four-Channel Diversity Receiver / Transmitter Set
- 1 x ACT-747B receiver
- 4 x ACT-72TC bodypack transmitters
The ACT 700 series is robust and can be used flexibly and professionally in a variety of applications. The bright color VFD (vacuum fluorescent display), which is unique in the industry, offers a wide viewing angle on the high-contrast and crystal-clear display of all parameters. With a further improved 3rd generation RF and IF circuitry, the receivers offer excellent and superior audio and radio quality.
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.
