Overview

The ECM-88FPT is suitable for a wide range of applications in TV and live performance. Based on the experience of having produced over five million professional ECM microphones, the ECM-88FPT delivers exceptional audio performance in a tiny package. The ECM-88FPT is a beige-coloured model supplied without a connector (pigtail), enabling users to choose connectors according to their transmitter.
Versatile applications
The ECM-88's minute size means it can be used in a wide range of applications, including as an 'on camera, lapel mic' which can be sewn into a theatrical costume. Apart from voice amplification, the ECM-88 can be used for many other applications where space is limited or the microphone has to be concealed.
Superb sound quality and low handling noise
The ECM-88's 'dual rectangular diaphragm' structure delivers excellent sensitivity, low noise and a flat frequency response. This structure also minimises cable handling noise, improving its performance in challenging conditions, for example a windy outside broadcast.
Convenient packaging
The ECM-88 model is supplied in a robust carry case with 'tie-clip' and 'Dracula' type holders and space for the DC-78 power supply unit. (ECM-88PT is not supplied with the holders).
Resilient construction
The ECM-88 has been designed for 'real life' environments, for example the microphone is water resistant so providing protection from sweat ingression.

Features

Miniature ECM capsule (3.5 x 3.5 x 16.8mm)
The ECM-88 capsule is approx 50% of the volume of the current Sony ECM-77 microphone.
Unique dual rectangular diaphragms
This structure allows the microphone to deliver impressive sound and noise handling performance.
Flat frequency response
The microphone has a flat frequency response and can therefore be used for voice and musical instrument recording.
Compatible with Sony wireless microphone systems
The ECM-88 model is terminated with a 4-pin connector that is compatible with certain Sony wireless transmitters (for example WRT-8B or WRT-822).
Ready for use as a wired microphone
Using the combination of the ECM-88 with the DC-78 power supply, allows the microphone to be configured as a wired microphone (with an XLR connector).
