[QUOTE="Brad Weber, post: 116280, member: 114"] Re: Labgruppen C-series power output rating confusion Amplifiers have both a maximum voltage and a maximum current thay can provide for the output and the output for lower impedance loads may be limited by the maximum current supported. In the case of the C 48:4 those limits are apparently 141V and 17.5A respectively. By Ohm's law, P=I**2 X R and P=V**2/R and thus for 2 Ohms that is 17.5**2 X 2 = 612.5W for the maximum current and 141**2/2 or 9940.5W for the maximum voltage, so while the voltage could support a much greater output it is apparently current limited to approximately 600W into a 2 Ohm load.
