cable and power adapter. The H2's microphones, functionality, and use of standard USB and SD interfaces make it suitable both for recording high-quality sound and in many speech applications. The H2 has been cited by various oral history associations, such as
Oral History Association The Oral History Association (OHA) is a professional association for oral historians and others interested in advancing the practice and use of oral history.Vermont Folklife Center as an affordable option for recording narrator interviews. The H2's rate of data transfer via the USB 2.0 port is "full speed" of up to 12 Mbit/s, the same as USB 1.1 and much slower than the widely available USB 2.0 Hi-Speed of 60 Mbit/s. The H2 can be powered either by two standard AA batteries or a power adapter. Recording time with low self-discharge 2000 mAh NiMH batteries is about 6 hours for mp3 bitrate set to 128 kbit/s.


Recorder features

The H2 can record in WAV format (at 96, 48, or 44.1 kHz in either 16 or 24 bit depth). Recording to compressed MP3 format at up to 320 kbit/s or VBR is supported in the 2-channel recording mode. Officially the H2 supports SD

cards, but some SDHC cards of up to 32 GB capacity have been confirmed by Zoom to work. The H2 has a three-way gain input switch, with settings for low (useful for loud sounds, such as a live rock band), medium, and high (useful for speech, such as one or two people podcasting in a quiet room.) Other features of the recorder are:
LCD Display
Four internal microphones
2-Channel Stereo recording up to 24bit/96 kHz
4-Channel Stereo recording up to 24bit/48 kHz (Creates two sound files)
W-XY mic patterns with 4 mic capsules and signal processing allows Front 90° cardioid, Rear 120° cardioid and 360° polar patterns
Time Stamp and Track Marker functions in Broadcast WAV Format (BWF)

Comparison with Zoom H4 recorder

Unlike the larger H4 Handy Recorder which succeeded it, the H2 does not include ports to accept XLR or 1/4-inch connectors, but has standard 1/8-inch (3.5mm) external microphone and line level inputs. The input jack for external stereo microphones supports plug-in power. The H2 has built-in microphones, but allows external ones to be used if different characteristics are required. Unlike the H4, the H2 makes no provision for

Design changes and delays

The H2 began shipping on August 21, 2007. This was delayed from the original May 2007 shipping date as an additional microphone was added; the original three-microphone Mid-Side design was lacking in some respects, and was abandoned in favor of the four-microphone W-X/Y design. The built-in high-fidelity electret condenser microphone capsules are arranged to allow stereo recording and have user-selectable parameters to allow for either a 90- or 120-degree pickup angle. The H2 can also be used to record a 360-degree soundfield.
