1600W Power Amplifier + Speaker Protector

1600W Power Amplifier + Speaker Protector
Power amplifier with high power output that is greatly needed by many audiophiles. Especially for field or concert, and in addition to the SPL car audio designation. Eg for controlling the use of extreme subwoofer speakers. So it takes a lot of power.
And the following is a power amplifier circuit that can generate output power up to 1600Watt at 4Ohm speaker load. In addition to having a large power, the power amplifier is already equipped with the protection of speakers. The function of the protection speakers is that the speakers are protected by DC voltage which can damage the speakers. It also can cut off the output current when the circuit occurs, so the power amplifier circuit remains safe.

Back to the discussion of this power amplifier. This power amplifier uses 4 final sets of 2SC3264 and 2SA1295 transistors. Where each transistor can flow current up to 18A and has power 200W.

To get a large power, the role of power supply amplifier is very important. Power supply for this amplifier at least 20A with max voltage 100V.

Why PCBWay is the best PCB Assembly Manufacturer?

As an electronic engineer, we often run into a situation: you have a new idea and designed the circuit schematic, but feel overwhelmed if prototype, purchase components and assembly by yourself.

Considering everyone’s needs, here we recommend you the most suitable PCB Assembly Company ---PCBWay

PCBWay is a Chinese manufacturer with over 10 years' experience in PCB prototype and assembly service. They have helped so many electronics engineers assemble projects. Their excellent service wins wide reputation from all over word engineers. The following are a few reasons why we recommend PCBWay Assembly Service.

1. PCB Assembly service only $88/10 pcs and Free Shipping
To help more electronic enthusiasts build projects at a lower price, PCBWay decided assembly price dropped to $88/10 pcs and the free stencils (usually frameless is $10). What is more, they added a production line last month to upgrade their assembly service, it helps reduce delivery time significantly.

HiFi Class-D Discrete Power Amplifier

HiFi Class-D Discrete Power Amplifier
Hello, friends this time I will share the scheme of class-d power amplifier circuit using discrete components (transistors, resistors, capacitors) without using IC. The power amplifier can produce output power 200 Watt to 500W RMS, which only use final transistor Mosfet N-channel as much as 2 pieces. In this circuit, I use 2 pieces of final transistor IRF540. This IRF540 MOSFET transistor can control voltage up to 100V with maximum current 28A continuously. So I just use the transistor for the final amplifier (switching PWM). Power amplifier class-d super HiFi can be supplied up to 45V DC CT. and for circuit schematics also PCB Layout design I can see below:

Subwoofer Filter 4558 complete Regulated Power Supply

Subwoofer Filter 4558 circuit

Hello friends, this time I will share the 4558 filter subwoofer circuit which is similar to the previous filter subwoofer. Why is a subwoofer filter needed for a power amplifier circuit? For the important problem of whether or not it depends on the usefulness of the power amplifier itself, whether the power amplifier is devoted to subwoofer speakers or not. If so, then this subwoofer circuit is very important.

Usefulness is very good, but it also can clarify the low tone and eliminate the middle tone and high tone, so that bass issued by subwoofer speakers getting kicked. Back to the topic of this subwoofer circuit, this circuit I design and I modify it by adding a regulated power supply circuit by IC 7815 and 7915.

Class-D Power Amplifier Circuit D1K5

On this occasion, I will share the power amplifier circuit, power amplifier circuit with the class-d system. The power amplifier is very good used for large power. This power amplifier can be supplied from 65V to 95V DC with a minimum current of 10A or better. And can generate power up to 1500Watt RMS, so big is not it?

The D-class amplifier is an electronic amplifier that uses transistor switching as the primary method for power, unlike class A, class B, or AB-class linear amplifier that uses the active resistance of the transistor. Therefore, this amplifier has a higher benefit, with additional results for the required heat sink. Filter the LC pass under smoothing the pulses.

The efficiency of a high D-class amplifier stems from the fact that the output stage never operates in a linear or active state. The output of the D-class amplifier consists only of ON or OFF. When the appliance is alive, the current that flows is maximum, but the voltage that runs it is ideally zero, and when the appliance dies, the voltage that stretches it is maximized, but the current that flows is zero.

Power SOCL504 2.1 Channel Amplifier

Power Amplifier SOCL 504 for stereo + subwoofer speakers
This is my project about Power Amplifier SOCL504, which I applied for the use of 2.1 (stereo + subwoofer) speaker system. Why am I using this SOCL504 driver for the use of 2.1 speaker channels? Yes, because the power amplifier driver is very suitable for use in various places, both in the homeroom and outdoors. And for the sound produced is also very satisfactory. Adopted from a variety of modifications SOCL504 power amplifier, this circuit highly recommends for you who like to make audio power amplifier.

And below for the SOCL504 power amplifier circuit that I combine to get a power amplifier with a 2.1 channel speaker system.

Power SOCL504 2.1 Channel Amplifier Circuit Schematic
Circuit Description
There are 3 sets of power amplifier SOCL 504, in the blue and green line is using for stereo (satellite speaker's) and the red line is using for subwoofer speaker. The 3 power amplifier SOCL504 I have prepared for its preamplifier you can see here: 2.1 Channel Preamplifier.
The difference between the stereo and the subwoofer amplifier is found in the capacitor of the A1837 and C4793 driver transistors. For stereo power amplifier I use 220pF and my subwoofer uses 100pF. What is the purpose?
The goal is to place high-frequency output. The higher pico size of the capacitor, the high tone gets bigger so the treble sound will get out but its make more noise also. And the right value is 220pF and the subwoofer amplifier uses 100pF.
In addition to capacitors, the final transistor is also different. Only in number, for stereo amplifiers use 1 set 2SC5200 2SA11943 and subwoofer amp using 2 final sets of transistors. It aims to distinguish the output power and power amplifier power to control the small or large power speakers. And obviously for subwoofer speakers will need more power so that I put 2 pieces of the final transistor for the subwoofer amplifier.
The power supply uses a bridge diode that I give the capacitor to filter and coupling AC to DC circuit. and my capacitors bank and filters use 24 x 680uF - 1000uF / 100V and 4 x 100N / 275V. The input AC voltage is very wide, starting from 20V AC - 75V AC CT.

Speaker impedance: 4-8ohm
Supply voltage: AC 20-75V CT MIN 10A 
Final Transistor: Toshiba 2SC5200 NPN, 2SA1943 PNP
Channel: 3 channel (left, right, subwoofer) using this 2.1 Preamplifier Circuit
Total Output power: 200W * 2 + 600W * 1 subwoofer (Upgradable)
Output matching: 4-8 ohm
Frequency response range: 14-100khz
