Operational Notes Transformers The isolation characteristics of transformers are superior to other balancing techniques for the adverse and uncontrolled environments of field production. Transformers provide complete galvanic isolation from the driving source, meaning there is no direct electrical connection. Signals are “transformed” magnetically.
MP-1 Microphone Preamplifier User Guide and Technical Documentation Batteries The MP-1 is designed to operate on two AA alkaline cells for approximately 26 hours with typical signals (without phantom power). The audio performance of the MP-1 does not vary throughout the life of the batteries. Many factors affect battery life including—battery chemistry, ambient temperature of operation, phantom voltage, microphone current draw, and output drive level.
