The Sony ECM-88B is a miniature omni-directional electret-condenser microphone ideally suited for quality-critical applications in broadcasting, theater and field production. This lavalier mic achieves high-sensitivity and has a flat-and-wide frequency response. The ECM-88B offers extremely low handling noise with unparalleled high sound quality.
The ECM-88B comes with a DC-78 power supply and it has a cable length of 8.2 feet. This model is best suited for wired lav mic applications. However; with the DC-78 power supply disconnected, the ECM-88B's 4-pin (SMC9-4P) connector can also be used with Sony WRT-822B and WRT-8B wireless mic body-pack transmitters.
