The response and cardioid pattern of the Sennheiser e 604 drum microphone is optimized for use on drum sets, while also producing exceptional results on brass and woodwinds. Sennheiser e 604 mics handle very high SPLs, with clear, balanced, low-distortion signals similar to high-end studio condenser mics. Lightweight voice coils provide extended high frequency and rapid transient response. Tough reinforced fiberglass bodies take knocks and shocks and suppress impact noise.
