Amplifier board information: Supply voltage: DC ± 20V to ± 95V It is recommended to use in ± 40 to 80V, the transformer output is the AC voltage, AC voltage needs to be rectified through the filter input to the power amplifier board. Speaker protection power AC9V-15V (AC single voltage), the transformer output directly input. Effective output power: 500W / 8? (± 95V power supply) 1000W / 4? (± 95V power supply) 1000W / 2? (± 65V power supply), the power amplifier board voltage 80v, for a higher supply voltage, need to replace the pressure Higher capacitance. 2? load is not recommended to exceed ± 65V, the power supply output power is basically determined by the supply voltage and speaker impedance, the lower the voltage, the smaller the power. Class A power: 100W (rms) ± 45V power supply, load 8?, total quiescent current 2.5A Total Harmonic Distortion: <0.01 10W / 8Ω Frequency response: 0Hz-160KHz (-3dB) Conversion rate: 25V / uS Signal to noise ratio:> 95dB Gain: 40 times Amplifier board size: 245mm × 65mm × 30mm × 2 (single PCB size) With radiator size: 260mm × 120mm × 80mm × 2 (block) Package Included: 2 Amplifier Board with 2 heatsink
