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 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… (added 4/02) |
|
Stereo Mixer (Randy Linscott) - 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...(electronic schematic / circuit added 2/05) |

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….(electronic design added 6/07) |
|
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.... (added 10/05) |

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 - This circuit is used to convert a mono audio signal
into a stereo signal that can be panned between the left and right channel by a 0-10V
control signal, it is intended for analog synthesizer systems….(electronic design
added 6/07) |
|
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) |
