Precision-audio-waveform-generator
This circuit generates sinusoidal, square, and triangle waveforms simultaneously. The frequency can be set to a specific value or varied as indicated. An operational amplifier can be added for enhanced drive capability and simplified amplitude adjustment. Additionally, a simple comparator...
stereo
This audio amplifier design utilizes two LM3886 chips per channel in a parallel configuration, based on the PA100 parallel amplifier detailed in National Semiconductor's application note AN1192. The amplifier can deliver approximately 50W into an 8-ohm speaker and 100W into...
Audio Booster circuit
The amplifier's gain is nominally 20 dB. Its frequency response is primarily influenced by the values of a few components, mainly C1 and R1. The schematic diagram's component values yield a frequency response of ±3.0 dB from approximately 120 Hz...
Audio Odd Block KT88 Series 1 Tube Amp-Power Supply
A schematic of the ability accumulation is presented below. Similar to the amplifier schematic, the ability accumulation design is © OddWatt Audio, and permission to host the schematic on this platform has been granted by OddWatt Audio. The schematic may...
Simple Audio Amplifier Circuit Using LM386 PCB
This is a simple low-power audio amplifier circuit capable of producing a power output of 1W. The mono amplifier circuit is built around the LM386 integrated circuit, which operates effectively at low voltages, even below 9V. This low-voltage amplifier is...
Car active subwoofer
The loudspeaker is designed to fit within a fixed enclosure, with its outer diameter matching the diameter of the paper tube for proper installation. The speaker is mounted on wood, with a wooden brush applied to the upper chamber, which...
Audio Oscillators
The discussion has focused on oscillators that utilize L-C tuned circuits, which create a 180° phase shift due to inductive or capacitive coupling, in addition to another 180° phase shift produced by the transistor itself. These L-C oscillators are widely...
New Phono amp
Very interesting points Chris and Thorsten, but I would like to take a moment to revisit my latest design, which is represented in the attached schematic.
The attached schematic represents a recent design that integrates various electronic components to achieve a...
Universal Audio Line Amplifier
A line amplifier is a valuable component for matching line signals or increasing their levels. This functionality is essential during recording sessions or in public-address systems. Additionally, multiple line amplifiers can be combined to create a line mixer. The amplifier's...
