TAS5630B 300W Class D Amplifier Circuit

| 2019/07/09

The core of the whole amplifier circuit is the TAS5630B one connection is based on modified the recommended BTL mode stereo input, which is listed by the manufacturer in Selection of the final chip involvement consisted of four different modes, of the optional input pins M1 to M3: TAS5630B 2 x BTL – two separate…

20W Stereo Amplifier With TDA2003 Tone Control

| 2019/06/14

Many times we have been asked about an amplifier that can be powered with the computer source to amplify this. We have also seen the need for an amplifier that can be transportable everywhere and that provides an acceptable power service. Thinking about filling these expectations, we present a 20W stereo amplifier (10W per channel)…

Build a Frequency Divider (crossover)

| 2019/06/12

To reproduce the audible bandwidth, three speakers must be used to complete the audible spectrum, since a single speaker can not emit the frequencies; Between 20 hertz and 20,000 hertz, this audible band is divided into three speakers, like this: Woofer – Responds to low frequencies. Medium (MidRange) – responds to mid frequencies. Tweeter –…

18dB 20Hz 200Hz Subwoofer Crossover Circuit

| 2018/05/18

Electronic Active Crossover Circuit Subwoofer Crossover NE5532 The audible band is in the frequency range 20 Hz to 20 kHz. Signal loud speakers are used, but they are not capable of transferring the entire audible band. Speakers are also used broadband that transmits most of the band but not whole. They still have a problem…

Reverb Effect Circuit PT2399 Guitar effects

| 2017/10/01

The way to create the “Reverb” effect can be divided into two types: mechanical and electronic, depending on the operation principle. The first and at the same time the oldest solution is the spring arrangement. In the second solution, analogue or digital delay lines are used. Effects built with springs give old-fashioned color, but the…

400W Claas D Subwoofer Amplifier Circuit IRS2092

| 2016/06/19

IRS2092 Subwoofer 400W Claas D Amplifier Circuit.The main part of this protection circuit is a transistor FET which is connected in the power supply branch amplifier integrated circuit IRS2092. When applying a positive voltage to the control electrode of the transistor, the ground power supply voltage and the comparator halts the modulation process. The transistor…

Audio Input Selector Circuit

| 2016/06/06

The main parts of the switch inputs is the decimal counter CD4017. Resistors R5 and R6 serves to limit the input current to the counters and, together with capacitor C1 form the RC divider. His task is to prevent multiple switch, when pressing a button, the influence of mechanical oscillations of the contacts of the…

TDA1524 Preamp Tone Control Circuit

| 2016/06/06

Preamp circuit is TDA1524 from the company Philips. His involvement This circuit can with a minimum of external components to change the volume, balance, treble and bass. Its advantage is that all settings adjustment is performed by changing the voltage on the corresponding pins of the circuit and that for both channels at the same…

MAX5406 Audio Processor Preamplifier Projects

| 2016/06/05

MAX5406 The proposed preamplifier is imposing several requirements. The preamp must allow volume control and balance (distribution of volume between channels), then it must allow the correction of the frequency characteristics. These requirements are satisfied by a number of integrated circuits intended for realization of the lna. These circuits, in all cases using to control…
