ACT-343
The MIPRO ACT-343 is an analog diversity wireless microphone receiver (4-channel receiver system).
Frequency range: 518-542 MHz, 620-644 MHz, 644-668 MHz, 823-832 MHz registration-free (center gap).
The innovative wireless microphone systems of the ACT-300 series are the result of years of extensive experience in the design and manufacture of microphone and radio systems. The four-channel receiver comes in a rugged 1U EIA standard 19" metal housing.
The ACT-343 four-channel receiver also has a practical volume control per channel for individually controlling the individual channel volume.
With a backlit LCD display instead of a conventional LED version, the ACT-343 makes for a more user-friendly and professional appearance.
Thanks to the PLL synthesized technology, the radio systems impress with excellent RF stability between transmitter and receiver.
The ACT-300 series combines professional features, user-friendly operation and excellent quality at an affordable price.
