Omnidirectional electret condenser, ultra-mini 3.5mm size, 20Hz"20kHz response, 125dB SPL max, low noise, 3.9ft cable, shielded for digital wireless.
The Sony ECM-90BC is an ultra-miniature, omni-directional electret condenser lavalier microphone engineered for demanding audio applications such as ENG (Electronic News Gathering), studio work, EFP (Electronic Field Production), and location sound. Its dual-diaphragm design boosts sensitivity, widens the dynamic range, and significantly lowers self-noise. The microphone's advanced diaphragm mounting structure is crafted to minimize handling and cable noise-making it especially suited for mobile setups where movement is constant.
This model is praised for its natural sound reproduction, achieved through a flat and wide frequency response of 20 Hz to 20 kHz. Its water-resistant construction ensures it performs reliably in various environments, from studio interiors to unpredictable outdoor conditions. Additionally, the ECM-90BC is shielded for compatibility with digital wireless transmitters, making it a flexible and robust solution for professional broadcast and film production scenarios.
Despite its technical prowess, the ECM-90BC remains incredibly discreet. Measuring just 3.5 x 3.5 x 20.5 mm and weighing only about 1 gram, it can be easily hidden in costumes or attached subtly to clothing, perfect for visual media where microphone visibility must be minimized. It connects via a Sony 4-pin (SMC9-4P) connector and operates with a DC input of 1.1V to 10.0V, making it compatible with a variety of professional wireless systems. The package includes essential accessories like a windscreen and tie clips to facilitate immediate use across different setups.
