sE Electronics sE7 SideFire Small-Diaphragm Condenser Microphone

The sE Electronics sE7 SideFire (SE7-SF-U) is a compact, side-address small-diaphragm condenser microphone designed for precision recording in tight or unconventional spaces. Its unique 90° capsule orientation facilitates unobtrusive placement, making it ideal for close-miking instruments like acoustic guitars, brass, and drum kits, as well as for creative overhead or underhead configurations.

Built upon the trusted sE7 platform, the SideFire variant retains the high-quality back-electret condenser capsule, delivering natural, balanced sound with excellent transient response. The cardioid polar pattern ensures focused capture with minimal background noise, while the all-metal chassis provides durability and efficient rejection of electrical interference. With its transformerless design and state-of-the-art electronics, the sE7 SideFire offers pristine sound quality across a wide frequency range.
