POWER METER SCHEMATIC For AUDIO AMPLIFIER CIRCUIT DIAGRAM
When the speaker resistance is 4O, then, make R1=10kO, if the resistance of speaker is 8O, make R1=8kO, and if the resistance of speaker is 16O, make R1=30kO.
The absence of peak detector or the detector will of averages give the circuit a fast reading of instantenous power, and this Gives us insight of both average and peak condition. For more readable peak or average mesurement, you cans use peak or average detector circuit.
