Earfonia PBA
(Pseudo Balanced Amplifier)

2 channels, 3 channels, or 4 channels amplifier (balanced), how much improvement will we get by having more channels? I started a proof of concept project last year to test it. This project is not about making an amp to be compared with other amp, but a...

วงจรออโต้วอลลุ่ม เนื่องจากปี2546
ผมได้ไปสถานีวิทยุ
ผมได้ไปดูเขาจัดรายการครับ
ผมเห็นเขาพูดแล้วลดวอลลุ่มลง
พอพูดเสร็จก็เร่งเสียงเพลงขึ้น
เร่งขึ้นเร่งลง เห็นแล้วผมสงสาร วอลลุ่มมากครับ
ผมจึงได้แนวคิดมาทำเป็นวงจรออโต้วอลลุ่มครับ
เวลาพูด เสียงเพลงจะลดลงเองครับ

Sound Activated Automatic Amplifier Mute Circuit

The following article presents a simple sound operated/activated amplifier muting circuit which enables the amplifier to silence itself as soon a voice or an external sound occurs across the detector MIC. The circuit was requested by Mr. Seok...

Introduction: Class-A 2SK1058 MOSFET Amplifier
I wanted to construct an amp that had zero negative feed back (0NFB), was pure Class-A and definitely single-ended. Nelson Pass has done a lot of work in this area with his Zen builds, but I wanted to go beyond Zen. I wanted to build a Zero Component...

DIY Class-A Headphone Amplifier
Not thrilled with how a computer soundcard drove my 32 ohm Grado SR80 headphones, I decided to build myself a desktop headphone amplifier for the office. In this instance I had plenty of voltage gain, but the sound card just runs out of gas with good headphones. This...

This 200 Watt high quality power audio amplifier will give you top class quality for loudspeaker 4 – 8 ohm. Frequency range 20-20000Hz, Voltage 24-36V with current max 5A. You need heatsink to keep the transistor from overheating.
Itu use dual polarity power supply to work, then...

In the electrical sector, a schematic diagram is usually used to describe the design or model of equipment. Schematic diagrams are usually utilized for the maintenance and repair of electronic and electromechanical devices / units. Original schematics were made by hand, using standardized templates...

stereo_tone_control_board.jpg
If you have an audio preamplifier whose "tone control" does not fully satisfy you, you may replace the existing stage with this stylish 3-way stereo tone control circuit which can act not only on treble and bass, but also on mid tones. The circuit is able to...

This topic continues the coverage of audio tone controls. The first entry started with a Passive Tone Control circuit using different RC filter configurations and introduced an active filter. The second entry showed a fully designed 2-Band Active Tone Control circuit, and now this third section...

Description
The circuit constitutes a natural extension of Mic-Line balance unit, but can be adapted to any other audio circuit. It is made up of two units in the series : A) A classic unit bass/ Treble and B) a parametric unit of mid frequencies. Both units can also be used autonomously or each...

Subwoofer booster circuit is used to enanching or boosting or increase the subwoofer amplifier, but it also can improve the quality of the bass sound on an amplifier or High Power Amplifier. Subwoofer booster circuit / bass enhancer circuit based on the IC 4558 and TL074 or commonly known as IC...

Το EQ-2 είναι ένα κύκλωμα γραφικού ισοσταθμιστή 6 περιοχών ρύθμισης . Κάθε περιοχή ρυθμίζεται από τα ποτεσόμετρα RV1-6, τα οποία είναι ,για καλύτερη οπτική ένδειξη των ρυθμίσεων, συρόμενα. Αυτό δεν σημαίνει ότι δεν μπορούμε να τα αντικαταστήσουμε με απλά ποτεσόμετρα. Στο κέντρο της...

As opposed to the widespread Baxandall circuit (dating back to 1952!) a ‘paraphrase’ tone control supplies a straight frequency response as long as the bass and treble controls are in the same position. This unique property makes the ‘paraphase’ configuration of interest if only treble or bass...

Overview

The circuit was designed to create a classic electronic crossover circuit that will provide a 3-way output on all loudspeakers.

Terminology Electronic Crossover – an external electronic signal processor that functions as a filter by limiting or blocking some range of...

22 Watt Car Subwoofer Amplifier
22W into 4 Ohm power amplifier, Variable Low Pass Frequency: 70 - 150Hz

This unit is intended to be connected to an existing car stereo amplifier, adding the often required extra "punch" to the music by driving a subwoofer. As very low frequencies are...
