2x30W (stereo) Amplifier with STK465 - A amplifier of acoustic frequencies can
be manufactured with discernible materials, despite is known so much the difficulties
of finding of materials, what the problem of regulations. These difficulties are
overcome relatively easily if we find amplifier in form completed….(design added

4 Channel Stereo Audio 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....(circuit added 8/06) |

A Soundfield Simulator for Stereo Headphones - An adaptation of the Linkwitz
acoustic simulator (see An Acoustic Simulator for Headphone Amplifiers by Chu Moy
above) as a front-end for headphone amplifiers with very high input impedance, such as
the author's own headphone amp project (see A DC-Coupled, Selectable-Gain Headphone
Amplifier). This circuit features a continuously adjustable Soundfield control.

Big Ear 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 6/06)

FM Stereo Transmitter - You'll find that this is a very easy project to build. It
will transmit good quality sound in the FM band ( 88, 108 mhz ). One inportant item is
that the IC chip operates on 3 volts DC. The chip will get destroyed if it is operated
on any voltage higher than 3.5 volts….(added 08/08/08) |
