Portable Digital Pocket Receiver
The 2.4 GHz frequency band (2.4 – 2.4835 GHz) was one of the first free frequency bands worldwide and is very well suited for spatially limited applications or applications with low transmission power. Based on the long experience in the development of professional digital wireless microphones, MIPRO has now developed its own digital technology for wireless microphones in the 2.4 GHz range, which minimizes interference from other devices and at the same time ensures high transmission quality of the microphone signal.
The ACT-2400 series from MIPRO is thus an interference-free and stable working digital but nevertheless inexpensive wireless microphone system. The system works with a double antenna true diversity technology with FSK modulation and achieves ranges of up to 100 meters without interference and dropouts. By using the FHSS frequency hopping method, each channel can select one of 4 different frequencies. The algorithm programmed into the system continuously searches the frequency band for interference-free frequencies and adjusts them accordingly.
FSK: Frequency Shift Key Modulation
FHSS: Frequency Hopping Spread Spectrum
