What it does Active inline microphone preamplifier that provides up to +28 dB of clean gain to boost lowsensitivity microphones without adding audible noise. Designed to be inserted between a passive ribbon or dynamic microphone and the downstream preamp or mixer, improving signal level and drive. Key benefits (why you need it) Solves low microphone volume: +28 dB of gain raises weak signals from passive ribbon and dynamic mics to usable levels for mixers, recorders, and interfaces. Lownoise amplification: the amplifier circuit is engineered for low noise, preserving detail and clarity while increasing level. Stronger downstream drive: the Class‑A amplifier and MP5+ transistor deliver lower output impedance and higher load capacity for reliable performance into a wide range of preamps and inputs. Simple setup: true plugandplay operation — connect the unit to the microphone's XLR output and route to your preamp, console, or recorder. Technical highlights Gain: +28 dB Circuit topology: CLASS‑A amplifier design for linear, lowdistortion performance Output stage: MP5+ transistor providing low output impedance and robust load capability Noise performance: lownoise design suitable for preserving microphone detail Compatibility and function Built for passive ribbon and dynamic microphones with standard XLR outputs. Works inline with existing preamps, mixers, audio interfaces, and field recorders — no internal power or complex wiring required beyond standard XLR connections. Functions as an active preamplifier to raise mic level before the downstream preamp, reducing the need for extreme gain settings on consoles or interfaces. Practical applications Studio recording: Boost a passive ribbon or lowoutput dynamic mic to achieve levels into a channel strip or audio interface without increasing noise. Live sound: Improve onstage clarity for lowsensitivity microphones so house preamps don't have to add excessive gain, reducing hiss and instability. Location and field recording: Use inline gain to feed portable recorders or wireless transmitters from lowoutput microphones while maintaining signal integrity. What makes it stand out Combines a clean +28 dB gain boost with a Class‑A amplifier topology and MP5+ transistor output stage for a balance of low noise, low output impedance, and strong loading capability. Straightforward XLR plugandplay connection minimizes setup time and technical complexity. Notes for users Intended for passive ribbon and dynamic microphones; connect to the microphone's XLR output and then to your preamp, mixer, or recorder input. Designed to improve usable level and drive without altering the microphone's tonal character beyond the natural benefits of a Class‑A amplifier and solid transistor output stage.
