ACT-311B
The MIPRO ACT-311B is an analog diversity wireless microphone receiver (1-channel receiver system).
Frequency ranges: 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 single-channel as well as the dual-channel receiver come in the rugged 1 / 2U EIA standard 19" metal housing.
With a backlit LCD display instead of a conventional LED version, the ACT-311B and ACT-312B make 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.
