Notes:

1. Rated power supply voltage for double ±70V, voltage in ±55-- ±80V can work normally (overvoltage burn out is not included!) If it is a ring bull, the voltage will fluctuate with the power grid because it does not have the stabilizing function. Please use the margin. Do not connect the positive and negative terminals of the power supply wrong so as not to burn out the board

2. The power supply is recommended to be the dc double power supply ±70V filter good power supply

3. 10-18 inch 4-euro 8 speakers are recommended for speakers

4. Although the audio output is protected by short circuit, try not to short circuit

5. Please check carefully before power on and make sure the wiring is correct before power on.

7. The voltage magnification of this plate is fixed at 50 times. If the output power is not enough, add the front stage magnification by yourself according to the specific situation.

8. The board to double DC power supply (3 lines of the kind, do not understand please baidu) single power not! No way! No way! Supply voltage ±55V ~ ± 80V, too low to work, too high easy to burn plate. The maximum effective power of the board is 500W (when the RMS value of 1V is input for ±75V 4ohm load)

9. According to the formula of power P = U * * voltage/U/R = voltage load, the power is determined by the voltage and the load, high voltage, small load, the greater the power, the board power supply voltage range refers to the voltage in this range board can work normally, not all the voltage and the load power is marked as high power output, for example, 12 v power supply 4 load, maximum 15 W, 8 when the largest power 7.5 W; 24V power supply 4 ohms, maximum power 50W, maximum power 25W 8 ohms; At any time, the power of the power supply must be greater than the power of the power amplifier, otherwise the high volume will not move, the power will be reduced and broken, unable to reach the corresponding power output.

Note:New parts and in original factory package!
