12V Power Amplifier Subwoofer using TDA7388 IC

Elcircuit will share the scheme along with the PCB layout for the power amplifier subwoofer that operates on a single 12V DC voltage or can use a 12V DC battery. The circuit and PCB layout were designed by Barlex Respectaizer. The following schematic and PCB layout, you can also download it at the end of the post.

The circuit use TDA7388 as the power amplifier and it upgradeable to TDA7560. For the Active Lowpass filter, I use a NE5532 IC. I design this project suitable for car subwoofer, motorbikes audio modification event, home, and everything that comes with 12V battery or transformer. The circuit is made as simple as possible with standard through-hole Components that easily found in the store. There are 2 potentiometer settings: -Frequency cross over -Subwoofer Volume It needs single supply 12Volt/10-15A If use with transformer, you may need external bridge diode to make DC voltage.

Discrete Power Amplifier Class-D UcD Superlite - Single Layer PCB

I have often posted this Discrete Class-D UcD Superlite because this power amplifier has quite an impressive sound quality, clear sound, and has a wide frequency response, mid and high sounds can be clear. And has a bass sound character that tends to be soft and deep. So this high-efficiency amplifier can be used for high-quality audio classes. Can be used for professionals or for home audio.
The UcD Superlite amplifier circuit was designed by Mr.Kartino Surodipo, a class-D Amplifier master who often designs class-d power amplifiers that are distributed free of charge, on Facebook Groups and on diyaudio.com forums.
And in this post elcircuit shares this PCB Layout Power AMplifier D-class UcD Superlite with a Single-layer PCB design. This PCB layout was designed by Mr. Ruzzel Rotao from the Philippines. The following PCB Layout Pictures, you can download this layout with PDF format below, and the amplifier also works 100% please try, good luck

TDA2030 Stereo Amplifier + Tone Control

TDA2030 Power Amplifier is a power amplifier based on chip or integrated circuit (IC), where the IC also has the similarity of TDA2050 and LM1875, both gainclone amplifier categories. This power amplifier is in great demand by various groups, because the price is relatively cheap, and many components that are used in the market, and amplifier assembly is not difficult. In this post, there is a series of TDA2030 Stereo Power Amplifier and also equipped with Tone Control, the use of stereo amplifiers can be used for home audio, with the low-cost category. The following circuit diagram Stereo TDA2030 + Tone Control:

5.1 Surround Sound Decoder

The circuit of 5.1 surround sound decoder (audio  5.1/ Dolby Prologic), this circuit serves to convert analog signals stereo or 2-channel, into 5.1 ch. By using the non-digital decoder method, so this circuit processes analog signals with the IC Op-Amp 4558, so that signals that were stereo can change to 5.1 or 6 channels, namely Left, Right, Center, Rear Left, Rear Right, and Subwoofer. This circuit works with a 12V symmetrical voltage (12VDC CT). The following PCB Layout (Electro India) and its component list,

TDA2030 2.1 Power Amplifier Circuit
Hello friend, in this post I will share the schematic and PCB Layout for power amplifier 2.1 channel system, using the TDA2030 Chip Amplifier, because of the many requests with the TDA2030 amplifier chip intended for home audio especially 2.1 Power amplifier (Stereo amplifier + Subwoofer Amplifier), I make a circuit and PCB layout that can be downloaded as a PDF file and PCB layout in a Gerber file, which makes it easier to buy PCBs at the PCB manufacturing fabrication. And no less important for list the components I also include in the form of a BoM file so that it's easy to buy the components, you can download the file at the end of the post.

200W HiFi Discrete UcD Class-D Amplifier

HiFi Discrete Class-D UcD Pleci is a D-class power amplifier with UcD topology, a topology that previously elcircuit had posted the Class-D UcD superlite amplifier and UcD X-Lite Fullbridge is an amplifier family designed by Mr. Kartino Surodipo, Class-D master amplifier from Indonesia. Here is a picture of the finished power amplifier from UcD Pleci amplifier. This amplifier at a glance like icepower250a 250W, but the design is not at all similar.
