The MCE 494 is a cardioid condenser microphone intended for direct connection to notebooks, mobile DAT- and MD-recorders. The microphone is powered from the microphone input of the connected device.

Due to its cardioid polar pattern, the MCE 494 has high gain-before-feedback (PC loudspeaker) and rejects background sounds such as drive noise.

The wide frequency response gives clear and precise voice reproduction with high intelligibility.
