Professional Beyerdynamic M500 Restoration Services
The Beyerdynamic M500 stands as a groundbreaking achievement in ribbon microphone design, representing the first successful handheld ribbon microphone when it debuted in 1969. This innovative hypercardioid ribbon microphone broke new ground with its compact single-ribbon design and revolutionary four-stage integral blast filter system, making it uniquely suited for close-proximity vocal applications while maintaining the warm character ribbon microphones are known for.
Revolutionary M500 Design Features
The M500 introduced several pioneering technologies that set it apart from other ribbon microphones of its era. Unlike traditional ribbon microphones with flat frequency response, the M500 features a deliberately shaped high-frequency response that enhances modern music applications. Its compact ribbon element measures only 0.85 inches in length and weighs just 0.00034 grams, representing a major technological breakthrough in ribbon design.
Technical Specifications:
- Element Type: Single Dynamic Ribbon
- Polar Pattern: Hypercardioid
- Frequency Response: 40 Hz – 18,000 Hz (rising high-frequency response)
- Impedance: 200 Ohms (low-impedance version available)
- Operating Principle: Pressure Gradient
- Ribbon Dimensions: 0.85 inch length, 0.00034 grams weight
- Built-in Filter: Four-stage integral blast filter system
Common M500 Restoration Issues
Typical problems affecting vintage M500 microphones:
- Ribbon element failure – Age-related deterioration, tearing, or complete breakage of the ultra-lightweight ribbon
- Magnetic gap debris – Accumulated contaminants, deteriorated adhesive materials, or metallic particles blocking ribbon movement
- Frequency response deviation – Loss of the characteristic high-frequency enhancement
- Complete signal failure – Total loss of audio output
