M-008 TDA7850 High Performance Portable Mini 4-Channel Power Amplifier 50Wx4 Output with 24V/6.6A Power Adapter

Description:
- TDA7850 is a high-performance four channel amplifier with low output impedance that can drive 2Ω speakers and has good control over most speakers on the market. At the same time, its output power is also high, capable of outputting a maximum power of 50W per channel on a 4-ohm load. This chip also has relatively low distortion. The specification sheet shows that under a 2 Ω load and 4W output power, its distortion can be as low as 0.006% or more, which ensures that TDA7850 can drive most speakers that are not very "power consuming", as well as many more "difficult to push" speakers.
- From a design perspective, this amplifier is equipped with a high current secondary voltage regulator module to supply power to TDA7850. The current output capability of this secondary regulated power module can reach up to 10A, which is used to drive TDA7850. The sound background is black, with many details and thick sound background. The two can be described as a perfect combination, fully utilizing the characteristics of TDA7850.
- This product requires a DC 24V adapter to work. We will not be responsible for free after-sales service for amplifier damage caused by improper adapter selection by users. Please understand.
- Both the two-stage linear regulator module and the power amplifier module generate a certain amount of heat during operation. When operating continuously with a certain output power, the aluminum alloy casing will generate heat, which is greater than that of a typical power amplifier. This is a normal phenomenon. According to the TDA7850 specification, the 7850 chip is allowed to have a junction temperature of 150 ℃. Based on actual test results, when the power amplifier operates continuously under high load on an indoor desktop and reaches thermal equilibrium (at room temperature of 30 ℃), the chassis temperature will remain stable within 75 ℃. At this temperature, the amplifier can operate continuously and stably. Everyone just needs to pay attention to maintaining a safe distance. If necessary, you can also add your own cooling measures.
