Sony ECM88B Miniature Omni-Directional Lavalier Microphone and DC-78 Power Supply

Add To Wishlist  |  Share This  |  Tell a Friend  
The 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. Other ECM-88 Series models include: the ECM-88BC; supplied with a 4-pin connector (SMC9-4P) optimized for wireless mic use (cable length 3.9 feet); the ECM-88BPT pigtail version (without connector), and the ECM-88FPT beige-colored pigtail version (without conector).
Price Options
  • Ideal for Broadcast, theater, field production and music applications
  • Omni directional dual-diaphragm design with unparalleled sound quality
  • Ultra-compact microphone capsule with a flat-and-wide frequency response
  • Extremely low cable handling noise
  • Water-resistant design
Feature Benefit Low handling noise Moving around while wearing a lavalier mic can often cause lav mic cables to rub against a users clothing. In many existing lavalier mic designs, this (frequently unavoidable) body movement can cause loud undesirable handling noise. The ECM-88B radically reduces this handling noise making it ideal for use in applications where users are moving. Flat-and-wide frequency response Many lavalier microphones are specifically optimized for speech reproduction and have limited use in other applications. The ECM-88B extends it's frequency response beyond the range of speech reproduction, and can be used for many high quality sound applications requiring a miniature mic that can easily be concealed.
