A very serious production of 2030 effect - an underestimated classic

The 2030 amplifier I made this time was carefully considered. During the entire production process, I was extremely serious! (The line I chose was the 1875, which is said to be 103dB , and the signal-to-noise ratio is extremely high)

I think many friends have misunderstandings about 2030, mainly for two reasons: 1. This integrated circuit is widely used in copycat amplifiers; 2. It is cheap, which also leads to doubts about its performance.

Through careful production, I think 2030 is definitely a good integrated block, its advantages are:

1. Each frequency band is very balanced;

2. The bass is particularly mellow, even better than that of 1875;

3. It adapts to the low-carbon era, has low energy consumption and is worth promoting.

However, 2030 also has its shortcomings. The biggest one is that it is a little bit powerless when driving a larger-caliber speaker , and it will be obviously distorted when the volume is slightly higher. Therefore, my 2030 is mainly used to drive a two-way 4-inch bass speaker . When listening to music at night , it feels good!

I didn't use the standard circuit , but the final effect is much better than the standard circuit!

I think the final sound effect depends on the overall equipment combination. When measuring the quality of an amplifier, it is best to compare different amplifiers in the same system , so that a more correct conclusion can be drawn! Therefore, it cannot be simply said to be good or bad without considering other matching equipment.
