SONY / ECM-100U

A small diaphragm condenser microphone that supports high-resolution sound collection. It faithfully collects the original sound of the instrument without coloring it.

The newly developed microphone capsule achieves high reproducibility up to 50kHz by reducing the thickness and weight of the diaphragm and reducing the acoustic impedance of the back electrode plate. In addition, polyetherimide (PEI), which has high strength and high insulation properties, is used as the insulating structural material after being processed with high-precision resin cutting. The capsule case and back electrode are made of brass cut with high precision. High-precision assembly processing achieves high-precision sound pickup with little distortion. Furthermore, by using a diaphragm vapor-deposited with 24K gold, high-purity sound quality is achieved. The ECM-100U achieves a frequency characteristic that extends flatly up to 50kHz. It is possible to pick up the original characteristics of the instrument without coloring it.

Inherits the ""resonance-proof housing structure"" adopted in the C-800G
The chassis is made of zinc die-cast with a high specific gravity to ensure vibration resistance and vibration control. The microphone housing is made of brass cut with a structure combining different metals, eliminating the muddy sound caused by unnecessary resonance and achieving clear sound.

Commitment to reliable products produced domestically
Professional audio products, such as the C-38B and C-800G condenser microphones and the MDR-CD900ST monitor headphones, are used in many recording studios. These are manufactured by Sony Taiyo, a Japanese factory that has been producing these products for many years. Each product is carefully assembled by hand by skilled workers under the strict quality control cultivated in the production of professional products.
