Links to electronic circuits,
electronic schematics, designs for engineers, hobbyists, students & inventors:
|
|
|
|
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) |
|
Single Ended Class A2 SV811 10 Stereo Amp - (circuit /
schematic design added 6/06) |
|
Stereo amplifier IC's outputs drive multiple loads -
21-Nov-05 Issue of EDN Reference provides constant bias voltage
regardless of supply-voltage variations.... [Design Idea by
Jean-Jacques Avenel, Maxim Integrated Products, Lesigny, France;
Edited by Brad Thompson and Fran Granville] |
|
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.... (added 10/05) |
|
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,… (added 10/05) |
|
Stereo Coder Multiplexer - With BA1404 and 15 KHz low pass filters.
….(electronic schematic added 11/08) |
|
Stereo compressor - (circuit added 6/070 |
|
Stereo Ducker - (electronic circuit added 7/03) |
|
Stereo Electret Microphone PreAmplifier - (circuit / schematic design added
6/06) |
|
Stereo FM Transmitter - AN-543-StereoFMTransmitter-Analog Device Application
Notes (app note added 6/06) |
|
Stereo Headphone Amplifier - This is an improved version of headphone amplifier
I've built many years ago. I wanted so much to share it with you because this simple
circuit has done a great service.... (circuit added 08/07/06) |
|
Stereo Line Driver - Power Amp Stereo Line Driver,This preamplifier has a low
output impedance, and is designed to drive long cables, allowing you to listen to a remote
music source without having to buy expensive screened cables. The very low output… [from
Andy Collison's website] |
|
Stereo Mixer - With this circuit you can mix four separate audio inputs. Each
input will accept high or low impedance microphones, phonograph, tape or aux signals. You
can adjust the gain of each input by adjusting each respective pot. With the Stereo/Mono
switch you.... [Randy Linscott] |
|
Stereo PreAmplifier - Simple circuitry suitable for moving-magnet cartridges.
Passive high-frequency equalization. (added 9/04) |
|
Stereo Preamplifier with Bass-boost Circuit - ….(design added 08/08)
|
|
Stereo Synthesizer - different frequency ranges appear at the two outputs,
depending on the setting of the controls and create a stereo effect (added 4/02)
|
|
Stereo Test Tone Generator - The purpose of this circuit is to create a pair of
sine waves for testing stereo equipment. While it is useful for many types of audio test
tone generation, the circuit is specialized for the purpose of aligning
an[[../fmst/index.html|FM Stereo Modulator]], like the type used in low power FM stereo
transmitters. Two tone outputs are available, the low tone has a secondary output that is
180 degrees out of phase with the primary output. The circuit is also handy for testing
computer sound card inputs. [G. Forrest Cook] |
|
Stereo Tube Amplifier (Aaron Cake) - The circuit is simple, yet is capable of
excellent performance. I designed it specifically for use as an amplifier for the digital
sound card in my computer. Audio input can be from any two-channel line level device such
as a television, CD player....(circuit / schematic design added 7/02) |
|
Stereo Width Controllers - 2 to choose from. Expand or contract the stereo sound
stage(circuit / schematic design added 6/06) |
|
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.... [(C) G. Forrest Cook January 1, 2005] |
|
Two Line Output Combiner - Convert consumer equipment stereo signal to mono or
combine audio signal from two different equipments to1-input (added 4/02) |
|
Voltage Controlled Panner Circuit - pans audio left and right [G. Forrest Cook] |
|
VU Stereo Meter - This project will indicate the volume level of the audio going
to your speakers by lighting up LEDS. The LEDS can be any color so mix them up and really
make it look good. The input of the circuit is connected to the speaker ….(added 05/02)
|
|
Wireless PLL Stereo FM TX with LCD - Now you can use your MP3 Player to listen
your favorite tunes through any FM stereo receiver. Wireless FM transmitter wirelessly
connects portable music players to your car or home stereo quickly and easily. Just plug
the FM Transmitter into the headphone jack of your MP3 or any audio source including iPOD,
PDA, CD Player, Cassette player or connect it to your PC or laptop computer. Tune your
card stereo or receiver to the clearest FM frequency, and enjoy your digital music with
full sound and convenience. |
