1) Each channel provides individually considered extremely high, load stableperformance at nominal impedances down to 2 ohms. The total power of all four channels is at practical burst signals typically 20 kW (40 kW for a short time). Will be permanently accessed more power than the power supply (mains and supply) can provide, so the hardware limiter will reduce the output levels. The hardware limiter should not be used as a signal compressor. It is up to the user to properly deal with the available power pool.
