1 Pair TTA1943+TTC5200 PR-800 Class A/AB 1000W Stage Power Amplifier Board
Power amplifier board information:
Supply voltage: DC ±20V to ±80V use (on-board filter capacitor voltage 100V capacitor, the power supply voltage can be increased by ± 95V), the transformer output is AC voltage, AC voltage needs to be input to the power amplifier through rectification and filtering board. Horn protection power AC9V-15V (AC single voltage), transformer output direct input.
Effective output power: 500W/8Ω (±95V power supply) 1000W/4Ω (±95V power supply) 1000W/2Ω (±65V power supply), the capacity of the power amplifier board is 80v, if higher voltage is needed, the withstand voltage needs to be replaced Higher capacitance. 2Ω load is recommended not to exceed ± 65V, power supply output power is basically determined by the supply voltage and speaker impedance, the lower the use of voltage, the smaller the power.
