ACT-828AVB
The MIPRO ACT828AVB is a Digital True Diversity Broadband Wireless Dual-Receiver (2-Channel Receiver System).
Frequency area: 482-554 MHz (5UA), 554-626 MHz (5UB).
MIPRO's new ACT-800 series digital wireless systems have a superb sound quality which can handle with any wired microphone. With up to 224 preprogrammed channels plus 16 freely programmable channels, the ACT-818 and ACT-828/848 receivers with 72 MHz bandwidth ensure optimum flexibility even for larger setups.
The single-channel as well as the dual-channel receiver come in a rugged 1U EIA standard 19" metal housing.
Due to the digital signal, the audio quality of the system is independent of the transmission distance and the transmission power. The digitization (24-bit / 44.1kHz) is higher than that of a CD.
A digital 256-bit key ensures a tap-proof radio transmission. Via a digital AES EBU interface, the signal can be transmitted loss-free over long distances via a wired connection (for example, to a digital mixer).
All in all, the ACT-800 series offers crystal-clear sound for highest demands at an affordable price.
OPTIONALLY: With DANTE Interface (version: ACT-828DNT - sold separately).
