Version 2 is now available with a new case design and soft rubber hand grips. Originally made popular by the “Inspire” project, atmospheric listening has become an accessible pass-time. Built on the research of these early receivers, the AR1 offers superior noise cancellation for trouble free listening even in electromagnetically noisy areas such as urban homes. A high quality audio chip set gives the best sound experience possible. The revolutionary loop antenna allows the unit to be truly portable for field work, or for instant listening pleasure in the home. Discover the magic of the Earth’s natural sounds.
Outdoor enthusiasts will find the AR1 just as friendly as those who wish to use computer recording and capture. Separate controls for receiver power and audio volume allow for optimal adjustment to any application. An audio output jack allows for the use of headphones, connection to a computer audio line-in or sophisticated recording devices such as oscilloscopes and data acquisition systems. For long term recording, an external power adaptor connection is provided. External antennas can also be used for special applications or research work.
The AR1 output head phone jack can connect directly to the line input of most laptop or desktop computers using an extension cable. Free capture software such as Audacity or your favourite sound software can be used to record and display events from the AR1. In this way, distant atmospheric events or local phenomena can be recorded for playback or analysis. Real time graphing is available using the Audacity interface.
