ACT-818
The MIPRO ACT-818 is a Digital True Diversity Broadband Wireless Receiver (1-Channel Receiver System).
Frequency area: 5UA (482-554 MHz), 5UB (554-626 MHz).
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 come in a rugged 1 / 2U 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 the digital SPDIF output, the signal can be transmitted loss-free over long distances (for example to a digital mixer).
All in all, the ACT-800 series offers crystal-clear sound for highest demands at an affordable price.
