ECM-2001 STUDIO ELECTRET A studio quality back electret cardioid microphone with a keen price. The ECM-2001 produces a smooth response extending from 25Hz to 18kHz and is held within close limits. This pre polarized small capsule design yields an excellent high frequency response as the diaphragm is so light that distortions fall in the ultrasonic and not the audio band. In addition, the output voltage from this design produces around 10dB more output thus reducing any mixer`s front end noise by a corresponding amount. Aside from traditional recording the 2001 is popular for sampling work. Powering by a standard AA type battery which should give over 1000 hours of use. An on-off switch is provided. Supplied complete with a 5m XLR-Jack lead.
