The Sony ECM-66B Lavalier Condenser Microphone is a compact professional mic crafted for accurate, natural sound reproduction of instruments and voices in both live and studio environments. Unlike standard lavaliers, it employs a cardioid polar pattern specifically designed to isolate the source and reject unwanted noise, helping minimize feedback in demanding audio setups. With an electret condenser capsule, the ECM-66B achieves excellent transient response, capturing subtle details with tonal accuracy and improved clarity. Its internal DC to DC converter elevates capsule voltage, allowing the microphone to handle sound pressure levels as high as 130 dB SPL without distortion, making it ideal for louder sources such as brass, amplified instruments, or powerful vocalists. For versatility, the ECM-66B supports dual powering methods, running from either standard 48V phantom power or a single AA battery, ensuring adaptability across portable and fixed installations. The included in-line power unit incorporates an on/off switch to extend battery life and an LED indicator for quick power confirmation. With its discreet black finish, lightweight design, and robust performance, the ECM-66B is a reliable option for presenters, musicians, and sound engineers. Complete with its battery power supply module, the microphone provides a flexible and durable solution tailored for professional audio production and live performance.Manufacturer Items Include:Sony ECM-66B Unidirectional Lavalier Condenser Microphone2 x Holder ClipsWindscreenProtective Carrying CaseBundle Items Include:Sony ECM-66B Compact Lavalier Condenser Microphone – Unidirectional XLR Lapel MicMicrofiber Cloth4x AA w/ ChargerMicrophone CleanerCable TiesXLR to 1/4 TRS
