Input Balance Power Amplifier 4558 - SMD

Input Balance Power Amplifier 4558 - SMD

Input Balance Power Amplifier is a circuit which will filter the original signal with a shadow signal so it will get a low noise input and a clear signal that will be forwarded to the power amplifier. There is a shadow signal or weakened signal from various interference on long cable input, so expect to use long cable at input either microphone cable or output cable mixer and other audio accessories.

This Input Balance circuit is suitable for installation on Yiroshi Amplifier, SOCL 504, or another power amplifier with no input balance.
This input balance circuit is highly recommended, and it is recommended to use long cable accessories. Do not underestimate the use of long cables, therefore long cable usage is often disrupted by wild signal either from radio frequency, wireless, or other signals. Besides being used for field audio, this input balance circuit can also be used for car audio that already uses a power amplifier, which can filter out wild signals into the car's power amplifier. Usually called audio storing, where the output power amplifier will issue noise that will be louder if RPM up. This input balance circuit can overcome these constraints.

Yiroshi Power Amplifier - SMD

This is my third project for Yiroshi Power Amplifier Circuit, the power amplifier circuit is very super quality, many have tested the power of this Yiroshi power amplifier. Power amplifier Yiroshi suitable for outdoor or indoor or used for the bass amplifier (subwoofer amplifier). Previously I have made this Yiroshi amp circuit in a stereo version of Yiroshi amplifier, which I have tested and worked well. 

But in this post, I make this Yiroshi power amplifier circuit by using some component of SMD (Surface Mount Device) in buffer circuit and its driver. Some components that I change to SMD eg 2N5401 transistors with mmbt5401, 2N5551 and mmbt5551 and some capacitors and resistors. And for transistor driver still use the same transistor as Yiroshi previous amplifier, as well as on the final part of the transistor which still uses 2SC5200 and 2SA1943. Here's the circuit scheme:

Power amplifier Yyiroshi SMD has a PCB design is smaller because it uses some SMD part and with double layer PCB design so that the path and components can be arranged as neatly as possible and as small as possible. This is the first design of Yiroshi Power Amplifier that uses SMD part, allows for future I will update again with PCB smaller and can be more quality again. Here's PCB Layout design:

6 reasons PCBWay is the best PCB manufacturer

There is an increasing number of online PCB prototype companies in recent years, and the price is getting lower and lower, which is definitely good news for an electronic enthusiast. So which company offer the most cost-effective service?

Here I recommend the highly acclaimed PCB manufacturer- PCBWay
Their high-quality PCB and perfect service win wide reputation from all over word engineers. Here are 6 reasons why we recommend PCBWay.

1. PCB prototype as low as $5/10 pcs

The goal of PCBWay is "Better, Faster, Cheaper". In order to help more electronic enthusiasts build projects at a lower price, they are the first manufacturer to announce PCB prototype price will drop to $5/10pcs. The actual PCB prototype price is $ 0 after using the coupon for new registrants. What’s more, the stencil only needs $10. And the same price for different solder mask color. Generally speaking, the delivery time of PCBWay is only 2-3 days.

PCB prototype as low as $5/10 pcs

High-quality Raw Material of PCBWay

2. High-quality Raw Material of PCBWay 

Compared with other PCB manufacturers who use low-quality conductive adhesive materials, PCBWay always insists on quality first, using high-quality raw materials. For detailed reference to “Refuse conductive adhesive technology in PCB manufacture” 

Different raw materials can cause a huge gap in quality. Professional evaluation agencies ever detected PCB copper thickness and raw materials flame resistance that from PCBWay are better than other manufacturers.

3. You can track PCB production progress in PCBWay background

Are you curious about your PCB production statue after place order? Many companies don't support such services, but in the PCBWay background system, you can see the progress of the PCB production and track the express number after shipment.

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.
