420W x 2 AC 24V TDA8954TH Dual-core Digital Audio Amplifier Board With CPU Fan Hifi Two Channel Amplifier

Note: The power amplifier board should be connected to the speaker first, and then the power supply can be turned on. The no-load power supply will cause the output stage to burn out. Specifications: Input voltage: AC24V4V Input current:>5A & 300VA Input impedance: 1k Input signal: 1.8V Channel: Two-channel Magnification: 33 times Output power: 420W * 2 Output impedance: 4-8 Type: AD class Size: 133*105*28MM Product weight: 495g Feature: - This power amplifier board adopts the new original imported TDA8954TH chip, which is produced by NXP. The chip is in the working state of AD class, which has the round sound quality of analog power amplifier and the high efficiency of digital power amplifier. - Designed for each channel with independent BTL mode output, power up to 420W, and the use of industrial graphics card-level fan heatsink, long-term operation can also effectively control the temperature within a reasonable range. Used to push 8 inch 12 inch speakers. 4 ohms can up to 420W per channel, 8 ohms can up to 210W per sound. Can be used as a pure final stage or as an independent amplifier is a good choice. Package Included: 1 x 420*2 TDA8954TH Digital Audio Amplifier Board
