    3.4. D12 power amplifiers the two power amplifiers fitted to the d12 can deliver 2 x 750 w continuous sine wave power into an 8 ohms load, increasing to 2 x 1200 w continuous sine wave power into a 4 ohms load. These maximum output ratings measured with sine wave are valid for minutes only until the...

    3.6. Power supply the d12 utilizes an autosensing switch mode power supply for mains voltages 115/230 v, 50 – 60 hz (optional 100/200 v) and overvoltage protection. Where voltages outside of this range are present, a self-resetting protective circuit responds quickly to isolate the internal amplifie...

    3.6.1. Inrush current limiter a mains inrush current limiter provides a "soft start" and enables several d12s to be powered up at the same time without overloading the mains power supply. The maximum current drawn during the power up phase is dependent on the mains voltage, however nominal values ar...
