ACT-747
The MIPRO ACT-747 is a Professional analog 4-channel true diversity broadband receiver, 19" metal housing, VFD display, ACT function, internal switching power supply, 400 preset frequencies.
Frequency area: 482-554 MHz (5UA), 554-626 MHz (5UB).
The ACT 700 series is robust and can be flexibly and professionally used in a variety of applications.
The 2-channel receiver comes in a rugged 1U EIA standard 19" metal case.
The industry's only bright color VFD (Vacuum Fluorescent Display) offers a wide viewing angle to the high-contrast, crystal-clear display of all parameters.
With further improved 3rd generation RF and IF circuitry, the receivers provide excellent and superior audio and radio quality.
The ACT-700 series combines professional features, user-friendly operation and excellent quality at an affordable price.
The two- and four-channel receivers can also be equipped with the optional digital Dante TM interface
