With an optimized acoustic design, discrete class-A circuitry and a transformerless output, this mic delivers clear, natural sound quality at all frequencies, without suffering from fizzy highs or a lack of low-frequency punch. The discrete electronics and the switchable attenuation pad ensure a high dynamic range, with high sound pressure level (SPL) handling capability and extremely low-noise components. The switchable low-cut filter helps eliminate rumble or footfall noise, and can also compensate for an excess of bass frequencies caused by the proximity effect. This enables the sE7 to close-mic many instruments, including electric guitar speaker cabinets, brass instruments and drums. Reliable operation (even in demanding on-stage applications in difficult environments) is ensured by the roadworthy all-metal design, robust construction, and high-quality manufacturing standards.
