Tweeter's delicate 120W power amplifier circuit diagram
The biggest advantage of the power amplifier introduced in this article is that the treble is delicate. The subtle sounds of various musical instruments can be reproduced without using the microphone, but the bass is powerful and soothing. During the interval between the tracks, the cough is almost silent. It is more suitable for amateur production because it is easy to obtain materials and has good performance.
It is believed that most electronics enthusiasts have used TDA2030A, TDA1514 and other excellent circuits to assemble simple amplifiers. However, even if they form high-power BTL circuits to connect VCDs and recorders, they still cannot make enough sound from the speakers. Caused by the front push level. If there is no front push, the BTL power amplifier composed of TDA2030A can only have a power output of about 10W. But after installing the front push, the maximum output power can be fully exerted, that is, the TDA2030A can also output shocking audio power.
Circuit principle:
Component selection and production:
Feature
B.Water resistance:It is made of high performance insulating resin. It has excellent air tightness and water tightness.The protection grade is up tp IP68.The IP68 is the highest protection grade, which prevents dust from entering and can operate reliably for a long time in the case of continuous flooding.
C.Fire resistance: Insulating resin is self-extinguishing insulating material, and fire resistance is class A;It can work in 950-1000 ºC fire more than 90 minutes, and keep the lines do not be interrupted.And the insulating resin contains no halogens and will not release harmful gases at high temperatures.
D.Corrosion resistance: Epoxy resin castable in Pouring Waterproof Busbar has excellent corrosion resistance and can effectively resist the corrosion of various chemicals.
E.Mechanical properties:It can withstand mechanical impact of 6 joules to ensure the safety of use and has good explosion-proof performance.
F.All-weather product:Using product is not restricted by altitude;Can work long time in the environment of the -40 ºC .Insulating resin will not crack.It can be used for a long time in the environment with the highest pollution level (level 4) both indoor and outdoor.
