Abstract

The low frequency device is a great instrument to use at the jungle and other places to detect the wild life. This instrument make human easier to find the animal by detect its sound. Beside that a fire fighter or rescue team to save human in building collapse. At the same time, army can also be using this equipment in their operation in forest to detect enemy. This devices was constructed by using application of the amplifier to make it can detect the distant sound which is can be hear by human ear. Typical low frequency device are monophonic, but this unit has a stereo audio path that helps produce more realistic sounding audio. This device can be used with headphones or as an audio source for a stereo tape recorder or a PC sound card. This circuit also works nicely as a remote stereo audio receiver for accompanying a video surveillance system. It is capable of operating on the end of a four wire shielded cable that is more than 100 feet long. For remote operation, a set of inexpensive amplified PC speakers can be connected to the output for monitoring the sound.
