Balanced NE5532 Mic Preamplifier

Compact 1-channel balanced microphone preamplifier built around the audiophile-grade NE5532 operational amplifier. Dimensions: not specified (per source); weight: not specified; input impedance: 10 kΩ via XLR female socket; output impedance: 100 Ω via XLR male socket; gain: 20 dB (unbalanced), 26–27 dB (balanced); frequency response: 20 Hz – 20 kHz; operating voltage: DC 5–12 V; power consumption: 0.5 W; enclosure material: metal; colour: black. The circuit is fully balanced and optimised for dynamic microphone signal amplification with low noise and high fidelity. Designed for clean, transparent gain staging in home studios, podcast setups, or field recording chains where XLR-level signal integrity matters. Ideal for connecting dynamic mics (e.g., SM58, RØDE M1) to line-level inputs on audio interfaces, mixers, or recorders lacking sufficient mic preamp gain — especially when long cable runs demand balanced transmission to reject interference.
