The Extron MP 101 is a compact, single-channel microphone preamplifier designed to provide clean gain and flexible connectivity for professional audio systems. Its primary function is to boost the low-level signal from a dynamic or condenser microphone to a line-level signal suitable for input into a mixer, digital signal processor, recording interface, or other audio equipment. This device is particularly valuable in installed AV systems, conference rooms, and classrooms where a dedicated, high-quality preamp stage is needed close to the microphone source to maintain signal integrity over long cable runs before further processing or distribution. It addresses common challenges such as insufficient gain, impedance mismatch, and the need for phantom power in a simple, reliable unit.

The preamplifier features a robust, metal enclosure and offers both XLR and 3.5mm input jacks to accommodate a wide range of microphone types, including lavalier and headset mics. For condenser microphones, it provides standard 48-volt phantom power, switchable via a front-panel button with a clear LED indicator. Gain control is achieved through a recessed potentiometer, allowing precise adjustment from minimal to significant amplification while maintaining a low-noise floor. The output is provided on both a balanced XLR and an unbalanced RCA connector, offering maximum flexibility for integration into different types of audio systems. This combination of features makes the MP 101 an ideal interface point between a single critical microphone and the core audio infrastructure.

Designed for simplicity and reliability, the MP 101 operates on external 12-volt DC power, which can be supplied by an Extron power supply or another compatible source. Its small form factor allows for discreet mounting under a table, inside a lectern, or in an equipment rack. By providing localized, high-quality gain and conversion, the Extron MP 101 ensures that microphone signals are strong, clean, and free from hum or interference before they enter the main system, which is essential for achieving clear, intelligible audio in speech reinforcement and conferencing applications.
