The Super Ear is an ultra high gain stereo audio amplifier! And when we say high gain, we mean it! It boosts audio 50 times and you can listen to it in stereo besides! Miniature high sensitivity microphones are placed at 45 degree angles to give you maximum separation. This little kit also includes an […]
This is a simple and low cost desktop headphone amplifier for the office. The amplifier concept is simple and follows a typical single-ended class A circuit utilizing an active constant current source (CCS) in place of a passive resistor. A CCS doubles the efficiency of the circuit over that where a passive load resistor is […]
This circuit is for detecting any audio signal with justable noise offset. It could be used to generate a radio mute signal eg. from a PDA. The circuit is consisting of:
