1. Board overall nice, reasonable layout, with the blue and yellow chemical capacitor large radiator, very beautiful
2. Green Oxidation large radiator, good heat dissipation
3. High-frequency low-impedance capacitors, stable and reliable performance, output distortion is smaller, powerful bass, midrange and treble clarity, sound sweet
1 Rated power supply voltage for dual ± 50V, the voltage at ± 42 --- ± 58V can work, because this amp has undervoltage and overvoltage protection, it is recommended not to lead nearly voltage supply voltage protection point, because if the power at high power voltage fluctuations, if the voltage is lower or higher than the scope of protection of the moment, was closed to protect the amplifier output, while the staccato, do not reverse the positive and negative power supply
2 power supply is recommended to ± 50V DC dual power supply filtering better
3 speakers recommended 6-10 inch 4 ohm or 8 ohm trumpet
4 Although the audio output short circuit protection, but try not to short-circuit
5 Check carefully before energized, make sure the wiring is correct before pass.
6 This panel voltage is fixed at 36 times magnification, if the output power is not enough, as the case may add their own pre-amplification

|Other Features||1. Supply Voltage: Dual DC power supply ± 42 --- ± 58V 2. Rated output power: 250W (± 50V power 4 ohms speakers, THD <= 0.05%) 3. Maximum output power: 300W (± 50V power 4 ohms speakers, THD <= 2%), for working at maximum power Please enhance heat dissipation, the board is rated at 250W) 4. Efficiency:> = 90% 5. SNR: 90dB 6. Total harmonic distortion: 250W (± 50 Power 4 ohm speakers, THD <= 0.05%) 250W (± 50 power 8 ohm speakers, THD <= 0.01%) 7. Frequency range: 20Hz-20KHz 8. Speaker: 4-8 ohms 9. Voltage Gain: 36 times 10. Output short circuit protection:Yes 11. That trumpet output DC bias protection protection:Yes 12. Voltage protection: Yes, 39V, 39V supply voltage drops below will protect the amplifier, turn off output 13. Voltage protection: Yes, 68V, 68V supply voltage is higher than the amplifier will protect, turn off the output 14 Over-temperature protection: Yes, radiators FET temperature higher than 100 ° C, turn off the output|
