[QUOTE="Ivan Beaver, post: 24875, member: 30"] Re: Help me understand system limiting- setting it When doing the calculations remember that the "amplifier" is a voltage amplifier-NOT a power amplifier. This is important when you think of it this way. At any point below the max output capability the following is true. It starts to be a bit "untrue" win a dB or 2 of full output. Let's say you put in 1 volt and the amplifier "puts out" 100 watts into 8 ohms. Now apply the same 1 volt input-but hook up a 2 ohm loudspeaker. The "power" being applied across that load is 400 watts. The voltage across the load is the same-irregardless of the impedance load (again below max outputs), so the voltage gain is the same, but the power output would be different. So you need to be careful to take the impedance of the loudspeaker into account when figuring out the applied signal. The more you think in terms of voltage-the better off you will be. [/QUOTE]
