Like all Zoom recorders, the H1s onboard microphones are configured in an X/Y pattern for stunning stereo imaging. Because both microphones are arranged on the same axis, they are equidistant from the sound source for perfect localization & no phase shifting. The result is great stereo recordings with natural depth & accurate imaging. The H1s built-in directional microphones focus on the sound being recorded. Unlike omnidirectional microphones, which pick up sound all around indiscriminately, the H1 microphones ignore the unwanted noise behind them. The compact, lightweight H1 is perfect for use on a video or DSLR camera. The remarkable depth & clarity of sound achieved by the stereo X/Y microphone design brings additional realism & depth to HD video. By combining the H1 with a DSLR video camera, you can create a professional video system with high-quality sound.
