The E303 directional boundary microphone is designed
for flat surface placement. The miniature condenser
capsule provides wide frequency response and reduces
reflections to minimize phasing distortion. Its clean and
high sensitivity signal results in clear sound without
coloration. It features a built-in pre-amplifier that doesn’t
need an external power adapter.
