Passive Crossover Circuit Schematics (2-Way and 3-Way Examples)

Many speaker crossover schematics are available in PDF format from Aaron Audio’s archive page. Passive crossover circuits are filter circuits that separate the audio signal coming from an amplifier into..

Audio Limiter Sound Level Limiter Circuit

Sudden increases in sound level can sometimes be not only disturbing, but also risky for speakers and connected audio equipment. The Audio Limiter is a practical analog sound limiter solution..

Stereo Three-Band Tone Control Circuit with TL084 (Hi-Fi 1995)

This HiFi stereo 3-band tone control circuit, prepared with the TL084 opamp, is used to adjust bass, midrange, and treble frequencies separately. It operates with a single supply between 12V-35V,..

Tweeter (Treble Speaker) Protection Circuit

The circuit effectively protects the sensitive tweeter within a speaker cabinet from overload. It was specifically designed to prevent damage to tweeters, particularly at high volume levels and under faulty..

SMD Resistor Potentiometer PCB for Volume Control

This is a project to repair a faulty volume control potentiometer on an Odyssey-U-010 amplifier. In the original setup, large resistors were soldered to the top. Instead of using a..

Phase Corrected Active Crossover High, Mid, Low NE5532

Active crossover is an improved solution for loudspeakers compared to traditional passive crossover circuits. It provides excellent flat system frequency response and reduced distortion. Phase-corrected active crossover: An active crossover..

Guitar Headphone Amplifier with Tone Control

“Mastery is gained through practice.” This saying is especially true for guitarists. However, loud guitar practice often leads to problems with neighbors. That’s where a compact and convenient guitar headset..

Loudness 10-Band Equalizer with Sliding Potentiometer

This 10-channel equalizer with loudness feature operates with a ±12V DC symmetrical voltage. Current consumption is approximately 40mA. The slider potentiometers are rated at 100 kOhm with a 30mm stroke…

Professional Electric Guitar Combo Amplifier

Combo amplifier system is designed to amplify and modify the signal from electric guitars. The signal is processed in two channels that produce clean or edited sound. The channels can..

Audio Echo, Repeat Effect Circuit PT2399

PT2399 circuit Heavy filtering allows for useful delay times and typical analog-like sound. The delay line starts just after 100n (after J112 JFET transistor). This capacitor is just a coupling..
