BulletPoint1 : J162/K1058 Field effect transistor amplifier board MJE15032/MJE15033,MJE340/MJE350 is adopted. The capacitance between coupling stages is 2.2UF, so the sound is natural and the sound field is wide.
BulletPoint2 : The five-ring metal resistor is selected as the resistance, and the five-ring metal film resistance with an accuracy of ±1% is used in the main circuit to ensure a good signal-to-noise ratio of the whole machine.
BulletPoint3 : PCB adopts 1.6mm thick double-sided plate, 2.0oz copper thickness, tin spraying whole process to ensure the good flow of large and small current.
BulletPoint4 : This board adopts the current advanced C1237 horn protection circuit, which can effectively eliminate the impact sound of on and off and DC output protection function, making your horn safer.
BulletPoint5 : The wiring layout of the whole circuit board is quite rigorous and reasonable, and the overall PCB wiring adopts one-point grounding mode. This power amplifier board has the advantages of stable and reliable operation, high output power, beautiful and round sound and open sound field. Strong three-dimensional sense, steady and powerful low frequency, excellent signal-to-noise ratio, wide dynamic range; clear details, excellent transient response, can play all kinds of music well.

ProductDescription :

Basic parameter requirements:
1. Power supply parameters: one set: DC +-40V (AC: transformer 300W dual 28V, need to add rectifier board).
Another group: single AC15V (Note: each board is powered independently by a single AC15V power supply, that is, a board is powered by a single AC15V power supply).
2. The power amplifier board can use master-slave integrated power supply, each channel uses 26-28V voltage, 6-8A current, officially recommended as DC 70V, so we do not exceed 80V, that is, plus or minus 40V working voltage. That is, the transformer output AC 26-28V. When the master and slave are supplied separately, the current amplifier is 26-28V, and the voltage amplification is 26-30V transformer voltage.
3. Class A 80W under 4 European load.
4. Horn impedance: 4-8 ohms.
5. This circuit is easy to debug, only need to adjust the static current, string the multimeter on the positive pole, set the multimeter to the 10A or 20A gear, adjust the potentiometer VR1 clockwise to 1.5A, this board has no temperature drift, there is no need to adjust repeatedly, this debugging is according to the recommended size of the radiator debugging parameters. If the radiator is too large or too small, the debugging will be changed, if the radiator is relatively large, the static current does not exceed 2A. If the radiator is too small, the temperature of the radiator does not exceed 60 degrees. When any point is reached, the static current should be reduced to ensure safety.
6. Radiator requirements: 350 X 150 X 50 (long. Wide. Tooth height) above 2KG is recommended.
7. Dimensions of plate including radiator: 328*120MM.
8. Weight: 0.65KG+0.65KG.
Packaging: a pair of KSA80 FETs Class A power amplifier board J162 K1058
