Technical Specifications

The DM2025-2K600 dynamic microphone capsule is specifically designed for wind instruments—especially saxophones—featuring a durable construction and focused acoustic performance. Its 20.4 mm cylindrical frame houses a robust coil and diaphragm system that delivers warm lows and well-defined mids, making it ideal for live sound reinforcement.

With a frequency response spanning 100Hz to 15kHz and a stable 600Ω output impedance, this capsule integrates seamlessly into clip-on instrument microphones designed for saxophones, with additional compatibility for handheld microphone applications in versatile live and studio settings. It provides clear and precise pickup of vocals and instruments while maintaining excellent feedback resistance.

Engineered to withstand demanding environments, the DM2025-2K600 is an excellent choice for manufacturers seeking rugged, purpose-built dynamic microphone elements tailored for both performance and communication applications.

Reliability Tests

High Temperature Test: Microphone subjected to +60℃ ±3℃ for 96 hours with 20-50% humidity, followed by 6 hours of normal temperature lay.

Low Temperature Test: Microphone subjected to -25℃ ±3℃ for 96 hours with 20-50% humidity, followed by 6 hours of normal temperature lay.

Humidity Test: Microphone exposed to 40℃ and 90-95% relative humidity for 96 hours, followed by 6 hours of normal temperature lay.

Temperature Cycle Test: Microphone subjected to rapid temperature changes from normal temperature to +60℃ ±3℃ for 1 hour (normal temperature lay for 3 hours) and then to -25℃ ±3℃ for 1 hour (normal temperature lay for 3 hours).

Sensitivity Stability: Sensitivity remains within ±3dB of the initial sensitivity after each environmental test.
