The rugged, water resistant Lectrosonics MM400C is based on Digital Hybrid Wireless™ technology, a revolutionary new design that combines 24-bit digital audio with an analog FM radio link. The result is outstanding audio quality plus the extended operating range of the best analog wireless systems in a package that can withstand the most extreme moisture and temperature environments. The MM400C is conveniently powered by a single AA battery, with internal switching power supplies providing constant voltages to the transmitter circuits from the beginning (1.5 volts) to the end (0.85 volts) of battery life. The 100 mW output with an RF circulator/isolator in the output stage provides excellent operating range while virtually eliminating intermodulation problems common in multichannel environments. The 4.5 hour battery life (lithium) is comparable to standard transmitter models operating on 9 V batteries.
