H2 Audio Recorders: Start to finish

January 25, 2010 by Sue Weier

You’ve checked out an H2 audio recorder. The case contains the following items, needed for using the recorder:

  • Recorder

  • Power supply
  • SD card – 4 GB, should already be in the recorder
  • Usb cable – to connect to a computer to transfer saved audio files, or to use as a microphone on the computer.
  • Desk stand – this is a 3-footed stand which screws into the bottom of the recorder.
  • Microphone stand adapter – this stand also screws into the bottom of the recorder, and is used when a conventional microphone stand or clip is available.
  • Ear buds – patron may prefer to use your own headphones/earbuds

  • Audio cable –to connect the H2 to a stereo system
  • Wind screen – for outdoor use, to screen the background sounds when recording outside.

The recorder can use two AA alkaline batteries in place of the power supply. The batteries are not supplied with the camera, but must be purchased by the patron.

Basic recording with the H2

  1. Turn the H2 on using the Power switch on the side.
  2. If you see a message saying "No Card", locate the SD card included with the H2 and insert it into the SD card slot in the bottom of the unit.
  3. Configure the mic pattern and input levels, if you are not using the default settings.  For more explanation of the configuration possibilities visit or open the H2 user manual attached to this page.  Adjusting microphone patterns and recording levels can provide better clarity in your final recording.
