The sE1a from soe Electronics is a professional, front-firing, small-diaphragm condenser microphone designed for recording and sound-reinforcement applications. Accurate sonic reproduction and high-SPL response make the sE1a ideal for percussion, electric guitar, keyboard cabinets, piano and most acoustic instruments.

High gain and quiet-output electronics result in a high-output signal and low noise floor. The front-firing design and cardioid polar pattern provide great attenuation of off-axis (side) ambiance and noise, resulting in maximum pickup of the desired signal. The sleek yet rugged design of the sE1a results in easy placement and positioning.
