Mipro ACT-747B/ACT-72T*4 Quad Channel Diversity Receiver with 4 Body Pack Transmitters

Features of the Mipro ACT-747B/ACT-72T*4 Quad Channel Diversity Receiver with 4 Body Pack Transmitters:
Enhanced RF circuitry greatly reduces interference and intermodulation.

MIPRO’s 3rd generation advanced RF and IF circuitry to improve anti-interference characteristics and

increase the number of interference-free channels available.

Auto Scan function allows quick search for an interference-free working channel from 104 preset

channels under 10 groups.

World’s first ACT™ function provides precise and rapid frequency sync to the transmitters.

True diversity receiving for best reception quality. Dual “PiloTone & NoiseLock” circuits minimize

interference.

Industry’s only full-color VFD screen delivers a bright, clear viewing in day or night environments with

automatic bright (working) and dim (standby) displays during performance.

All controls are intuitive and easily set up via a single rotary knob.

Industry’s only RF interference warning indicator for proper adjustments of the SQ level. Increase

sensitivity to extend receiving range; decrease the sensitivity to reduce interference.

Single channel or mixed output, switchable between three output levels for the best sound quality

options.

High dynamic range and high fidelity characteristics for transparent audio performance.

Receiver provides bias voltage for MIPRO antenna systems to enhance reception range and signal

stability.

MIPRO RCS.Net software allows real-time computer setup, control and monitoring.

Built-in 100 – 240V AC switching power supply ensures system safety and stability

72T

Ultra slim bodypack transmitter with sturdy magnesium alloy housing.

Innovatively designed battery cover allows easy access to operate buttons and prevents accidental operation.

Mute button with remote-control jack for easy activation of mute function.

On the top features mute switch, mini-XLR connector and antenna.

Backlit LCD displays all operational parameter information.

Stable PLL circuits. Automatically synchronized with the receiver’s frequency by MIPRO’s patented ACT™ function.

Can directly match to high-low input impedance for microphone or guitar without switching.

The input sensitivity is adjustable with six selectable gain settings.

Mini-XLR input with secure screw lock connector for lavaliere / headworn mics and guitar.

Adjustable belt clip allows wearing transmitter in up or down position.

High-efficiency circuitry design provides 12 ~ 14 hours of operation from 2 AA batteries (depending on the battery quality).
