Simple
Stereo Electret Microphone PreAmplifier: (circuit / schematic design added 6/06) |
|
Simple Two Line Output Combiner: Sometimes there is need to combine the output
of two line level audio sources to be fed to one input. A standard way in professional audio is to use a mixing desk, but on home audio system
you might want to look for a simpler and less expensive alternative.... (added 11/05) |

Stereo Audio Isolator: This circuit is useful for removing
ground loop hum on a remote line level audio signal line. It can be used to to connect a computer sound card to a stereo amplifier's line
input. Other uses include tapping into a line level signal for powering a remote amplifier, and removing common mode ground interference on 12
Volt audio equipment such as a car stereo. The circuit can be used in mono applications by simply ignoring the second channel.... (added 6/06) |

Stereo Broadcast Limiter: Circuit for the Ramsey FM10a/FM25 Transmitter (added 6/06) |
|
Stereo Channel Selector: The add-on circuit presented here is useful for
stereo systems. This circuit has provision for connecting stereo outputs from four different sources/channels as inputs and only one of them
is selected/connected to the output at any one time. When power supply is turned on, channel A (AR and AL) is selected. If no audio is
present in channel A,

The Big-E Stereo Parabolic Microphone: This device is a
stereo amplifier for a high sensitivity stereo parabolic microphone. It can be used for listening to distant sounds. Typical parabolic
microphones are monophonic, this unit has a stereo audio path that helps produce more realistic sounding audio. The Big-E 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 outputs for monitoring the sound....
