Product details
Increased horn relay protection, on delay, off instantaneous, effectively solving the impact of switching sound, needs an ex relay power supply, external 110V/220V AC can beThe board needs to be dual DC powered (3 wires)Single power supply will not work!Supply voltage ±45V ~ ± 70V, too low to work, too high to the board.The maximum effective power of the board is 500W (in the case of ± 65V 4- load input 1V rms)According to the power formula P = U * U / R = voltage * voltage / load can be seen, power by the voltage and load decision, high voltage, small load, the greater the power, the board for voltage range means that the voltage in this range board can work normally, not all voltage and load power is marked so high power output, for example, 12V power supply 4 Europe load, power maximum 15W, 8 Europe when the power maximum 7.5W; 24 V power supply 4 Europe, power maximum 50W, 8 Europe when the maximum 25W; at any time, the power supply power must be greater than the power of the amplifier, otherwise the loud volume can not carry, the power will be reduced and broken sound, can not reach the corresponding power output.Main technical s:1. Power supply voltage: dual DC power supply ±45--±70V (recommended +-65V power supply can be)2. Rated output power: 500W (±65V supply 4 load, distortion degree 1%)3. Efficiency: >= 90%4. Signal to noise ratio: 90dB5. Total harmonic distortion: 380W (±70 supply 4 speaker, distortion
