True stereo imaging:
Stereo recording is often accomplished by using two microphones in a V-shaped set up that faces the performer. While this method will result in good stereo separation, responsiveness for the area directly in front of the mics will be low, causing problems with depth perception and imaging. The Zoom H4 uses an X/Y configuration where the two microphones point inward at a crossing angle. This allows the recorder to cover a wide area, and at the same time capture sound sources in the center with perfect clarity and definition. Phase differences between left and right channels are also eliminated because sound is picked up simultaneously by both microphones.
Absence of phase differences ensures natural stereo imaging
24-bit/96 kHz linear PCM format and MP3 recording:
The H4 allows 24-bit/96 kHz linear PCM recording in WAV format, resulting in excellent transparency and definition that exceeds the sound quality of CDs. This is great for capturing the nuances of an acoustic instrument while preserving the ambience of the recording location. Or record directly as MP3 files for longer recordings that still provide excellent sound quality.
Secure Digital (SD) Media
The H4 records on Secure Digital (SD) Media cards. These widely available cards boast an amazing amount of recording time in a small package. And unlike tape or disc media, mechanical vibrations do not affect recording quality. With a 2GB SD memory card, the H4 can provide up to 190 minutes of stereo WAV file recording in 44.1 kHz/16-bit mode or as many as 34 hours when recording at 128 kbps in MP3 stereo mode.
Combination XLR-1/4" Inputs
The H4, with its two phantom powered XLR-1/4" input jacks that support direct connection of external microphones, is the solution to an infinite number of recording situations. You can also use the H4's Hi-Z rated phone inputs for direct connection of guitars, bass, or any other line-input device.
