Product details:
TDA7294 is a high-power integrated circuit with field tube output, which was created by the famous European SGS-THOMSON STMicroelectronics in the 1990s. It has completely changed the raw, cold and hard sound of previous integrated amplifiers, and is widely used in the HI-FI field. The design of the chip focuses on timbre, with high pressure resistance, low noise, low distortion, soft and audible timbre.
n Adopt new laser dark word TDA7294
n This board adopts 1.6 mm double-sided design, 2.0 oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents. The resistor is a metal film with a 1% error high-precision resistor, the small capacitor adopts the original Taiwan capacitor, and the coupling adopts the genuine German WIMA 2.2UF fever capacitor.
The wave adopts NOVER 10000UF/50V gold capacitors, and the rectification adopts 25A and rectifier flat bridge to ensure strong and continuous power support.
n The material of this board is exquisite, the circuit design is reasonable, the high sex-to-noise ratio, the sound quality is pure and sweet, and the details are outstanding. It is a cost-effective HIFI amplifier, suitable for speakers above 8 inches.
Basic parameters:
Output power: 160W+80W*7
Output impedance: 1-7 to 4-8Ω, bass can only be connected to 8Ω
Input voltage: +35V -0- -35V
Board Dimensions: 27.5 X 7.63 (cm)
Note: The output power of this power amplifier board is large, please install a large enough radiator! It is recommended that the radiator above 3KG, the IC metal part is negatively charged and cannot be grounded! When connecting the power supply of the power amplifier board, please discharge the filter board and then connect it to the power amplifier board, otherwise it will cause the TDA7294 chip to burn out asymmetrically.
