Sony ECM-88BPT Electret Condenser Microphone
The ECM-88BPT 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-88BPT offers extremely low handling noise with unparalleled high sound quality. The ECM-88BPT is supplied without a connector (pigtail) with a cable length of 8.2 feet. Other ECM-88 Series models include: the ECM-88B, supplied with a DC-78 power supply and optimized for wired mic use (cable length 8.2 feet); the ECM-88BC; supplied with a 4-pin connector (SMC9-4P) optimized for wireless mic use (cable length 3.9 feet); and the ECM-88FPT beige-colored pigtail version (without connector).
- 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-88BPT 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-88BPT 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. |
